The orcas expand their mouths almost 90 degrees and suck down some seawater. Then, when their neck pouch deflates, they force the saltwater out of the mouth while capturing krill and microscopic fish in their baleen.
The whale seems like a swollen tadpole as water flows into its mouth and stretches the pouch in its neck. The neck pouch deflates after roughly a minute when the majority of the water exits the whale's mouth and is discharged into the ocean.
When feeding, an adult blue whale may ingest up to 10,000 gallons of fresh water at once. But the whale forces the majority of the water out of her mouth and filters the food through her baleen, so she doesn't consume all of it.

What push factors do you think force many people from Syria to flee?
Violence: Since the start of the civil conflict, about 13,000 children have died or suffered injuries.
Infrastructure that has collapsed includes hospitals, clinics, schools, utilities, and water and sewage systems.
Who are Syrians?Generally, People often leave conflict in the hopes of quickly returning. So they relocate close by—possibly to relatives or friends in a neighboring town or just over the border—so they can continue to monitor their properties and sources of income.
But many Syrians have given up on that optimism in the wake of the more than five-year battle. There is little hope for peace since their houses have been destroyed and their families ripped apart.
Thousands of individuals are now prepared to go far further in search of the protection they so urgently need since they have nothing left and their exile locations are becoming more overcrowded.
The situation within Syria has only become worse, with war escalating in every area and the country's services and economy essentially in ruins. This not only encourages new individuals to emigrate but also has a significant influence on those who have already fled to nearby nations.

over the past decade there has been a lack of interest in sustainable agriculture. true false
Answer:
TRUE
Explanation:
Over the past decade, there has been a lack of interest in sustainable agriculture due to a variety of factors. One of the most significant factors is the relatively low cost of conventional farming practices, which make it difficult for farmers to justify the extra cost associated with sustainable agriculture. Additionally, the technological advancements in conventional farming have made it easier and more efficient for farmers to produce high yields, leading to a decrease in the need for sustainable agriculture practices. Furthermore, consumer demand for cheaper food has caused many farmers to prioritize quantity over quality, further decreasing the likelihood of sustainable agricultural practices being implemented. Finally, many governments have not offered the necessary incentives and support for sustainable agriculture, making it less attractive to farmers.

describe the transformation from snow to ice by arranging the following steps in order.
1. Pressure melts snow 2. Refreezing forms ice 3. Tightly packed fin forms. 4. Snow packs together.
The order of transformation from snow to ice is : Initially the Snow accumulates, then snow melts under pressure and forms Closely clustered firn and finally Ice is created by refreezing.
The correct order is 4-1-3-2.
When snowflakes are shaped into grains, they grab and crush air. Together, snowflakes take on new forms. Air bubbles between snow grains contract, and firn is produced. Snow turns into firn, which eventually solidifies into ice due to the weight of the ice.
The zone of accumulation is the region where glacial ice is formed. In this region, the amount of snow that accumulates each winter exceeds the amount that melts throughout the summer. Snow accumulations that have been buried transform into firn and then re-crystallize into glacial ice.

What happens to rocks beneath the Earth's surface?
Rocks are frequently pulled beneath the earth's surface by movements in the crust, where temperatures rise dramatically as they descend. Temperatures between 100 and 200 kilometers (62 and 124 miles) below the earth's surface are hot enough to melt most rocks.
Hot rocks from below can intrude into the cooler plate above as the denser tectonic plate subducts, or sinks below, or the less dense tectonic plate. This process involves the transfer of heat and the formation of magma. The magma in this subduction zone has the potential to form a series of active volcanoes known as a volcanic arc over millions of years.

How long can a killer whale be out of the water?
Naturally, whales are sea creatures and can live the best in the ocean. But if they ever are on land, they can survive only a couple of hours. If there is a way of cooling down the whale when it is on land, it can survive for a couple of hours longer.
After only a few minutes on land, the whale's own body weight would crush its organs without the ocean's buoyancy and weightlessness to hold it up. Also, due to the thick layer of blubber and lack of water, the whale would quickly overheat, get dehydrated, and dry out.
Whales lack any appendages that would allow them to move on land, hunt for food, navigate the land, or travel back to the ocean if they were to end up on land.

True. Tsunamis begin when some kind of trigger, such as an earthquake, landslide, or volcano, causes a large part of the surface of the water to rise or fall. After this sudden displacement of water, gravity acts to balance the water levels back, resulting in a tsunami.
In most cases, tsunamis are a result of very huge and long waves that arise from the sudden change and displacement of water in the ocean. One major characteristic of Tsunamis is that they cause displacement of water from the bottom to the top of the ocean, which makes them disastrous.
Earthquakes are the most common cause of Tsunamis. Due to the nature of the forces acting on the bottom of the ocean, the Tsunami travels as fast as a jet plane.
Apart from earthquakes and underwater volcanic eruptions, Tsunamis can result from tectonic disorders that cause huge displacements of the ocean.

what is the zone of wastage? what is the zone of wastage? the part of a glacier where water freezing exceeds snow melting the part of a glacier where snow accumulation exceeds snow melting the part of a glacier where snow melting exceeds water freezing the part of a glacier where snow melting exceeds snow accumulation
The zone of accumulation refers to the higher elevations of a glacier that are permanently covered in snow. The zone of wastage refers to the lowest part of the glacier where the ice is lost. Option (4) is correct.
A glacier with a negative budget is receding because it loses more volume than it gains. A retreating glacier may occasionally continue to advance downslope, but it will never be able to catch up to the melting glacier's much rapid rate of upward retreat. When the budget is balanced, a glacier does not advance or retreat. There is an accumulation zone and a waste zone.
The zone of accumulation refers to the higher elevations of a glacier that are permanently covered in snow. The zone of wastage refers to the lowest part of the glacier where the ice is lost. The erratically drawn line between these two areas is known as the snow line. The budget of the glacier and climate fluctuations influence where the snow line is located. A moving snow line down the glacier shows a positive budget, whereas a moving snow line up the glacier shows a negative budget.

How do sea urchins survive?
Intertidal sea urchins will pile rocks and shells on top of themselves to protect themselves. They dig scooped-out burrows in the soft rock over generations, sometimes trapping themselves in a self-made prison. Bacteria also have an impact.
Sea urchins are spiny, globular echinoderms in the Echinoidea class. There are approximately 950 species of sea urchins that live on every ocean's seabed and inhabit every depth zone from the intertidal seashore down to 5,000 meters (16,000 ft; 2,700 fathoms).
Sea urchins' spherical, hard shells (tests) are round and spiny, ranging in diameter from 3 to 10 cm (1 to 4 in). Sea urchins crawl slowly with tube feet and propel themselves with their spines.
Although algae are the primary source of nutrition, sea urchins also consume slow-moving (sessile) animals. Fish, starfish, crabs, and marine mammals are among the predators that eat sea urchins. Sea urchins are also eaten, particularly in Japan.

Answer:

Explanation:
How do Orcas sleep without drowning?
Similar to captive orcas, all adult killer whales now housed at SeaWorld have been seen to spend excessive amounts of time laying motionless at the bottom of their tanks and pools.
Because killer whales are biologically comparable to these species, it's hypothesized that they sleep in the same way. The respiration is controlled by the other half of the killer whale's brain while the first half sleeps. Additionally, only one eye is open (the one on the "awake" side of the brain), while the other one is kept closed. If someone asks if orcas sleep underwater, the response is a resounding YES. While their bodies fall asleep, only half of their minds do, allowing them to consciously remember to breathe.
Orcas can breathe more deliberately while sleeping at the surface, suggesting that every breath is significant. Usually, adult orcas spend between five and eight hours napping each day. The neonatal killer whales and dolphins behaved very differently from the older animals. For three weeks following their birth, the killer whale and dolphin calves did not exhibit any sleep behavior.

Why whales Cannot survive out of water for more than two hours?
Whale cannot survive out of the water for more than two hours because the blubber of whale cause overheating and reduce circulation.
Whales lives in deep freezing water and are pretty big. so if they end up washing ashore their bodies are suddenly under a lot of pressure and they end up overheating, burning in the sun and being unable to move. So they can’t really survive very long out of water. they need to get back in the water as quickly as possible. Toxins build up from the reduced circulation, poisoning the animal. Out of the water, a whale's thick blubber can cause it to overheat. Like other mammals, whales breathe air, so they can drown when stranded if water enters their blowhole at high tide.

describe the phenomenon of liquefaction in earthquakes and why it occurs. what happens? how can it affect buildings? what can be done to prevent damage to buildings in areas prone to liquefaction?
When an EQ causes shaking, the ground liquefaction, turning it into quicksand. Grainy materials contract as they settle, which causes water to rise to the surface. When an EQ ends, poorly constructed structures may tilt and be struck in a titled posture.
Liquefaction occurs when waterlogged, loosely packed sediments at or near the ground's surface start to lose strength as a result of violent ground shaking. During earthquakes, liquefaction beneath buildings and other structures can result in significant damage. During an earthquake, liquefaction is the process that makes soil behave more like a liquid than a solid. Sand and silt grains in damp soil underground are rearranged by the shaking, and the water between the grains is squeezed. Liquefaction is the term for the phase transitions from solid to liquid (melting) and from gas to liquid (condensation, respectively). The temperature and pressure at which a solid transforms into a liquid is known as the melting point (sometimes referred to as the liquefaction point). Prostate-derived serine proteases in the female reproductive tract are active enzymatically during the proteolytic process of semen liquefaction, which causes a gel-like ejaculated semen to turn watery.

The Köppen climate classification classifies climates into five major climate groups, with subgroups within each group determined by seasonal patterns of temperature and precipitation. A (tropical), B (arid), C (temperate), D (continental), and E are the five major groups (polar).
Geographers acknowledge a variety of elements that determine a region's climate: latitude. elevation. proximity to big water bodies, mountains, or other surface characteristics. The world is divided into five climate zones by the Köppen-Geiger system using hues and shades, which take into account factors like temperature and allow for a variety of plant growth. Based on regional vegetation, the Köppen climate classification system divides the world's climate zones into groups. According to Lumen Learning, climatic zones are identified by looking at the variables that frequently affect the actual climate. These variables include the local climate's temperature, humidity, precipitation totals and types, and the changing of the seasons. A region's average annual conditions for temperature, precipitation, winds, and clouds are referred to as its climate. Latitude, altitude, relief, currents and winds, as well as a region's distance from the sea, are the five key elements that influence a region's climate.
