To survive, otters need clean water in relatively specific, undisturbed environments. Sea otters need clean, watery habitats with plenty of prey.
Otters are good indicators of water quality. As predators, they are high up on the food chain. Sea otters must maintain a core body temperature of 37 degrees to stay alive but live in waters where temperatures can drop to -1 degree.
On the other hand, river otters are not found in highly-polluted watersheds. Their small numbers spread across wide ranges have made them extremely vulnerable to pollution, habitat destruction, and historical, unregulated trapping.

How do you find displacement example?
Total distance travelled d = 3 m + 5 m + 6 m = 14 m. A magnitude of the displacement can be obtained by visualizing the walking. The actual path from A to B as 3 m then from B to D as 5 m and finally from D to E as 6 m. |S| =√92+52 = 10.29 m.
An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a professor moves to the right in relation to a whiteboard. Displacement describes this shift in location.
What does distance displacement mean?
Distance is the length of any path connecting any two points. When measured along the shortest path between any two points, displacement is the direct distance between them. Since it only depends on magnitude and not direction, distance is a scalar quantity.

How long can orcas stay above water?
They typically only submerge for around 20 minutes, but various orcas behave differently. Orcas can only endure a brief period of time on land. They have no problems breathing. Their fat retains too much heat, which is an issue.
Without the buoyancy and weightlessness of the ocean to support it, the orca's own body weight would destroy its organs after only a few minutes on land. Second, the orcas would quickly overheat, become dehydrated, and dry out because of the thick covering of blubber (over 1 ft. of blubber in certain species) and lack of water.
Because they are animals, whales and dolphins also breathe air into their lungs like humans do. Since they lack gills, they cannot breathe underwater like fish can. They breathe through a blowhole, which is a pair of nostrils on top of their heads. orcas breathe air via their lungs to obtain the oxygen they require (like humans). However, they breathe through their blowholes, which are placed on top of their heads and serve as noses instead of mouths.

how does snow vary with temperature? snow has a uniform moisture content, but cold snow consists of larger crystals. warm snow is often called sleet because it is mixed with rain, but cold snow is more like hail with very large solid ice crystals. warm snow is powdery and light, while cold snow is moist. cold snow is powdery and light, while warm snow is moist. snow has a uniform moisture content, but warm snow consists of larger crystals.
Snow varies with temperature because it is mixed with rain, but the cold snow is more like hail with very large solid ice crystals.
What is Snow?Individual ice crystals that make up snow grow while hanging in the atmosphere, typically within clouds, and then fall to the ground, where they accumulate and alter further. By consuming sources of atmospheric moisture and frigid air, snowstorms organize and grow. By drawing supercooled water droplets that then freeze into hexagonal-shaped crystals, snowflakes form around airborne particles. Snowflakes can take on many different shapes, but the most common ones are platelets, needles, columns, and rime. It's possible for snow to blow into drifts as it builds up into a snowpack. Snow that has built up over time changes through processes like sintering, sublimation, and freeze-thaw. A glacier may develop in areas where the environment is sufficiently chilly for yearly accumulation. Other than that, snow usually melts seasonally, causing runoff into streams and rivers and refilling groundwater.

How do whales survive in water?
Because of a layer of fat called blubber that covers their entire body beneath the skin, whales can survive in deep or icy arctic water. Compared to the fat present in other mammals, blubber is substantially thicker.
The lungs of marine mammals are substantially larger than those of humans, allowing them to breathe in more air with each breath. Additionally, each time they inhale and exhale, they exchange more air. Additionally, their red blood cells contain more oxygen. Contrary to the buoyancy supplied by water, their bodies are not built to support that amount of weight on land.
Without the buoyancy and weightlessness of the ocean to support it, the whale's own body weight would destroy its organs after only a few minutes on land. Whales are marine mammals that live best in the ocean, but they cannot survive in freshwater conditions, at least not for very long. In actuality, all species of whales that are currently understood prefer saltwater habitats to freshwater ones for a variety of reasons.

what is the difference between faults and joints? group of answer choices joints are the result of compression, whereas faults are the result of tension. joints form from external stress, and faults form from cooling. joints form in place, whereas faults form because rock has moved. joints are the result of earthquakes, and faults are the result of weathering.
Answer: Joints form in place, whereas faults form because the rock has moved.
Explanation: A fault is a break in a rock mass along which movement has occurred. A joint is a fracture formed by the movement of the rock in a direction perpendicular to the plane of fracture.
Fault forms when rock above an inclined fracture plane moves downward, sliding along the rock on the other side of the fracture. Normal faults are often found along divergent plate boundaries, such as under the ocean where new crust is forming. Long, deep valleys can also be the result of normal faulting.
A joint is a type of extension fracture formed by the movement of the rock in a direction perpendicular to the plane of fracture. Joints form in solid rock that is stretched and its brittle strength (the point at which it breaks) is exceeded. When this happens, the rock fractures

the tremblor fault has a magnitude 4 earthquake every 5 years. the shaky fault has magnitude 6 earthquakes every 150 years. both faults can have earthquakes of the same magnitude and follow gutenberg-richter. which fault is more dangerous?
Shanky fault is more dangerous. An earthquake's magnitude is a numerical scale that is used to determine how much seismic energy is released as a result of the earthquake.
The Modified Mercalli Intensity Scale is a descriptive scale that is used to determine the intensity of an earthquake's shaking. Magnitude: The size of an earthquake is a numerical indicator of the magnitude of the earthquake at its source. The Richter Magnitude Scale gauges the seismic energy that an earthquake releases. The two terms used to describe earthquake characteristics are magnitude and intensity. The energy released at the epicentre of an earthquake is measured in magnitude. Measurements made with seismographs are used to calculate magnitude. The magnitude of the shaking caused by an earthquake at a certain site is measured by intensity. The amount of energy produced by an earthquake at its focal point determines its magnitude.
