Diseases, parasites, & predators are the three primary causes of mortality in orcas.
The killer whale seems to be an apex predator and is not known to have any natural predators when it pertains to prey and predator relationships. Except for people, parasites, and illnesses, which can seriously harm a killer whale's health.
It is possible that stress & boredom, two emotionally associated effects of captivity, cause the immune systems of cetaceans to be suppressed, resulting in infections, pneumonia, as well as other illnesses that cause orcas as well as other whales and dolphins to pass away.
According to new studies, humans may be a significant factor in killer whale deaths.

Apart from Earth, it is the only other body in the solar system containing liquid on its surface. Underneath Enceladus' icy surface, Cassini found that geyser-like jets discharge water vapor and ice particles from an underlying ocean. Galileo Galilei, an Italian scientist, was the first to observe Saturn with a telescope in 1610. He was surprised to see two UFOs, one on each side of the globe.

What is the speed of a point on the earth's surface located at 4/5 of the length of the arc between the equator and the pole, measured from equator? (hint: what is the radius of the circle in which the point moves?).
The speed of a point on earth's surface located at 4/5 of the length of the arc between the equator and the pol is 429 m/s.
How to calculate speed of point on earth's surface:The earth's radius is 6.37 × 10⁶ m, it rotates once every 24 hours.A point located 1/4 of the length of the arc between the equator and the pole, ([tex]\frac{4}{5}[/tex]) × 90° = 72°Since the arc angle of the line joining the equator and the pole is 90°, then the angle between the line joining the center and the given point, and the line joining center and the pole is,Φ = 90° - 72° = 18°
Sin Φ = (radius of the point ) / (radius of the earth)
Sin 18 = radius of the point / (6.37 × 10⁶)
Then we should look for the radius point by;Sin (18) = 0.3090
r = (6.37 × 10⁶) × 0,3090= 1,9683 × 10⁶ m
Speed of the point on the globe is v = 2πr / (24 hours), then2πr = 2π × 1,9683 × 10⁶ = 37095 × 10⁷ mThen we can look for the speed of the point by:v = 37095 × 10⁷/24
v = 1.545 × 10⁶ m/h
= 1545 m/h
= 429 m/s
Then the result of speed of point on earth's surface is 429 m/s.Learn more about speed of point on earth's surface here: brainly.com/question/1542471

Can orcas survive in hot water?
No, Orcas cannot be survived in hot water they prefer cold water.
These species seem to prefer cooler temperatures, even though they may be discovered in warmer waters close to the equator as compared to arctic waters. Orcas may go to semi-enclosed seas, river mouths, & ice-covered areas in addition to residing in deep ocean waters.
Whales and other marine mammals with warm blood may survive in cold water. Fat acts as an insulating material to assist whales maintain energy and warmth when they dive to freezing depths and cruise across icy seas, like those in Alaska.
Because of the increasing ocean temperatures, the killer whale is migrating further north in search of a new environment in which there are more sources of food and the water is cooler. On the other side, the ecology is negatively impacted over the long term by the movement of the dolphin species.

What is the relationship between temperature and water depth?
The temperature of ocean water varies with depth as well. Solar energy is reflected in the ocean's upper surface or rapidly absorbed with depth, which means that the deeper you go, the less sunlight there is. As a result, the water warms less.
When the upper water layers warm in the summer, a transition zone known as a thermocline separates them from deep water. The temperature drops rapidly with small increases in depth in a thermocline. Temperature stratification refers to the relationship between temperature change and depth.

How does water clarity affect sea animals?
Visibility and hence catchability are impacted by sea water clarity. If they can't see the bottom trawl net approaching, most fish species are less likely to be herded into it by peripheral equipment (sweeps and doors). When it's darker, pollock are also less likely to be at the bottom.
For instance, cleaning water enables more sunlight to penetrate aquatic vegetation below the surface. As a result, the vegetation generates oxygen, offers a home for fish and shellfish, and supplies food to ducks, fish, and animals. Clear waterways are also often regarded for their aesthetic appeal and recreational benefits. Some bodies of water have poor water clarity by nature.
The habitat and food sources of aquatic life, such as fish and aquatic birds, as well as the growth of aquatic plants, are impacted by poor clarity and excessive turbidity. Additionally, they may affect the aesthetic appeal and recreational benefits of rivers and streams. The suspended sediments, organics, and microbes present in seawater alter its transparency, and consequently the quantity of sunlight that can reach the leaves of seagrasses. Light attenuation is the term used to describe the loss in intensity of light over a specific distance as it travels through water.

watching what would be our current east coast/georgia area, during which period do the appalachian mountains first start to appear?
Cambrian period do the Appalachian mountains first start to appear. The Paleozoic Era and the Phanerozoic Eon were both preceded by the Cambrian Period.
An crucial turning point in the evolution of life on Earth occurred during the Cambrian Period, when numerous invertebrate species and the first fish-like vertebrates first appeared in the fossil record. The greatest record of Cambrian animal fossils, including soft-bodied creatures, may be found in the Burgess Shale. The Paleozoic era's Cambrian phase saw the most rapid explosion of evolution ever recorded. A staggering diversity of life, including many of the main animal groupings still extant today, emerged during the Cambrian Explosion. The chordates, which include vertebrates (animals with backbones) like humans, were among them. According to some experts, the appearance of predators was made possible by a slight, possibly transient increase in oxygen that abruptly crossed an ecological threshold. Carnivory's emergence would have sparked an evolutionary arms race that produced the explosion of various body kinds and behaviours that now populate the oceans. The team comes to the conclusion that a scarcity of oxygen and toxic hydrogen sulphide killed off a large number of Cambrian species. It is believed that similar circumstances led to the devastating Permian extinction 251 million years ago. According to Gill, there were multiple instances of fast extinction in the second half of the Cambrian.

What happens to the melting point of rock as the depth and pressure increases?
The higher the pressure at greater depth, the higher the temperature required to melt rock. If a lot of heat or pressure, the rock melts and turns into magma. This causes the formation of an igneous rock rather than a metamorphic rock.
Pressure: Pressure rises with depth, but as pressure rises, so does the melting temperature, so melting is less likely at higher pressures. Water: Adding water to rock changes its melting point. The melting point decreases as the amount of water molecules increases. Because most liquids are less dense than solids, increasing the pressure raises the melting point.

Spits form off of a headland due to decreased energy along the longshore current and deposition of sand .
What are SpitsA spit is a coastal landscape, a stretch of coastal material that projects out into the sea. It is connected to the mainland at one end. A spit thus has two ends.
The end that sticks out into the water is called the distal end, and the end that sticks out to land is called the proximal end.
How Spits Are FormedSpits are usually formed when a longshore current producing longshore drift strikes the beach at an angle. This usually occurs in the case of beaches or sheltered beaches such as bays or bays.
When the longshore current moves at an angle, and changes direction, the current spreads and loses a lot of energy.
The energy dissipation renders the waves unable to carry the full load of sediment, and thus sediment is deposited in the form of long rod-like features offshore or onshore. In this way, a spit is formed.

Water evaporates from a lake into the air, forming clouds. The clouds eventually form rain and it falls to the ground. The whole process occurs in the hydrosphere and atmosphere.
Hence, Option C is correct.
A type of vaporization called evaporation takes place on the surface of a liquid as it transitions into the gas phase. When humidity impacts the rate of evaporation of water, for example, a high concentration of the evaporating substance in the surrounding gas considerably slows down evaporation.A liquid turns into a gas during evaporation.
