When a whale dies it float over the ocean surface due to the gas build up and eventually they sink. It is called as whale fall.
When whale dies the body will float to the bottom . Once the body comes to rest biologists refer to this as a whale fall. other fish and sea animals initially eat the meat off the carcass. Bacteria that overtake a whale skeleton feed off the bones. The bacteria then produce hydrogen sulfide. Those thousands of chemoautotrophic sea creatures convert the hydrogen sulfide into usable energy to thrive and reproduce. Once a whale dies it may float at or near the ocean's surface for a few days due to gas buildup but eventually the carcass sinks, carried by ocean currents and often landing in the deep sea. These whale falls are rare but are most often seen along the migratory routes of living whales.

How a teacher can enhance the physical classroom environment to enhance learning and motivate learners better?
Teachers could use lighting & sound to create a relaxing atmosphere suitable to the various activities that take place during the day.
An atmosphere is a coating of gas several layers of gasses that envelops a planet and is kept in place by the planetary body's gravity. When the gravity is high and the temperature of the atmosphere is low, a planet preserves its atmosphere. A stellar atmosphere is the outer portion of a star that encompasses the layers above the transparent photosphere; low-temperature stars may have outer atmospheres including complex molecules. The stratified makeup of the atmosphere reduces the destructive effects of sunlight, UV radiation, solar wind, and cosmic rays, protecting organisms against genetic damage. The current makeup of the Earth's atmosphere is the result of millions of years of chemical change of the atmosphere through living beings.

What is the displacement of a fault?
Displacement, the separation between the offset marker's two ends, measured along the fault surface in the slip direction.
Over geologic time, most faults cause repeated displacements. The rock on one side of the fault abruptly slips in relation to the other during an earthquake. The fault surface may be vertical, horizontal, or at any other arbitrary angle.
The cumulative motion of the hanging wall over the footwall causes displacement even though slip along the fault changes instantly at the fault bend.
Extensional faults, regardless of their orientation with respect to the horizontal, cause the layers they cut to extend as a result of their displacement. Normal faults are dip-slip faults where the footwall and hanging wall have both descended relative to one another.
There are two types of displacement reactions namely Single displacement reaction and Double displacement reaction.

What can rival a orca?
Because orcas are apex predators, they are the dominant species in the food chain and have no rival. No competition can stand a chance against killer whales because they are among the biggest and most powerful marine creatures.
The term "rival" most frequently refers to an individual or group that seeks to dethrone or outperform another individual or group; hence, rivals frequently appear in pairs. According to Selbmann, in the vast majority of interactions observed near Iceland, killer whales appear to avoid pilot whales.
When things get heated, the pilot whales will occasionally pursue the killer whales at great speed, with both whales porpoising out of the water. Despite its reputation as a formidable opponent, the orca is superior to the great white shark in a direct confrontation. Orcas are smarter than dolphins and bigger. Orcas still have substantially greater metabolic rates than great whites because they breathe air, even though it is now recognized that they are warm-blooded.

The energy transfer occurring at each lettered area is:
A. Conduction B. Radiation C. Convection What are types of energy transfers?Heat energy is transferred through the mechanism of conduction when nearby atoms or molecules collide. In solids and liquids, where particles are more closely spaced, conduction happens more easily than in gases, where particles are more widely spaced. This is why A is conduction.
Heat waves are created during the radiation heat transfer process and may be absorbed, reflected, or transmitted through a cooler substance which is why the transfer of heat by fire is radiation.
Convection is the movement of fluid that allows heat to move from one location to another. Convective heat transfer combines the processes of conduction and advection, although being frequently mentioned as a separate type of heat transfer. This is why C is convection because the liquid in the kettle is moving around and heating the colder portions.

Whales use to sleep but as they are mammals they also have lungs and they use to breathe under the surface of the water. But when they don't have enough CO2 concentration they use to have sleep.
They don't start breathing until the CO2 levels are significantly greater than what humans can take, according to their brains. These processes, which are a component of the marine mammal diving response and aid in the sleeping process, are adaptations to living in an underwater environment.
Our involuntary respiratory system allows us to breathe even while our conscious mind is asleep. If an Orca were to fall asleep in the same way we do, it would be at risk of drowning.

The term Laurasia was used to describe the northernmost of two large landmasses/ continents produced by the breakup of Pangea.
Laurasia and Gondwana were the two continents which were formed part of the Pangaea supercontinent from around 335 to 175 million years ago. Laurasia was made of the present day continents of North America (Greenland), Europe, and Asia. The formation of these two continents by split of Pangea was described by Alfred Wegner in his continental drift theory. The rifting event was remarked by a huge outpouring of basaltic lava flows.

Do sea urchins like clean water?
In public aquariums, sea urchins are used as indicator organisms to determine if the system is working properly. This is due to their "pickiness" about water quality. If the water becomes contaminated, sea urchins will be the first to exhibit signs of stress, such as spines laying down or falling off.
Aristotle's lantern is a structure used by sea urchins to eat. It is made up of five hard plates that form a beak shape. They scrape algae off rocks with their beak-like mouth. Because scraping can wear down the plates, sea urchin teeth grow to replace them. Their mouth is on the underside of their body, and any waste is expelled through the anus at the top of the animal.
Sea urchins tend to congregate in colder, offshore waters, but they will occasionally venture into shallower waters in search of food.

what term describes continental drift? flora radiometric dating laurasia fauna gondwana plate tectonics pangaea
The concept of continental drift has been incorporated into the science of plate tectonics, which examines how continents move while riding on lithosphere plates. Abraham Ortelius initially proposed the idea that continents might have "drifted" in 1596.
One of the earliest hypotheses put up by geologists for how continents might migrate through time is called continental drift. The science of plate tectonics has now supplanted the theory of continental drift. The scientist Alfred Wegener is most closely connected with the concept of continental drift. Plate tectonics over millions of years produced continental drift. Additionally, plate tectonics clarified how the movement of the plates causes earthquakes and volcanoes, as well as how the collision of continents produced vast mountain ranges. According to the idea of plate tectonics, the land masses of the Earth are constantly shifting. Alfred Wegener was the first to recognize that Earth's land masses are in motion; he dubbed this continental drift. Here, he is seen in Greenland.

Adaptive radiation is used to describe a period characterized by very high rates of speciation.
A rapid growth in the number of species sharing a common ancestor that is characterized by high ecological and morphological variety is known as adaptive radiation. It is driven by organisms' ability to adapt to novel ecological situations.
Adaptive radiation is responsible for the diversity of Galapagos finches. Their beaks have altered in size and form during evolution, allowing them to adapt to a variety of diets: some species primarily consume animals, while others prefer seeds or plants; some forage in trees, while others do it on the ground. The variety of settings and food choices are what drove the quick differentiation of these finch species.
