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.

a. Most meteorites come from asteroids. b. Iron meteorites come from the cores of larger objects. c. Some stony meteorites resemble cooled lava d. Like most meteorites, stony meteorites come from comets and asteroids.
Answer:
Based on what we know about asteroid and comet impacts on Earth, all of the statements in the list are correct.
a. Most meteorites come from asteroids. This is true because most meteorites that reach the Earth's surface are believed to come from asteroids, which are rocky objects that orbit the sun.
b. Iron meteorites come from the cores of larger objects. This is also true, as iron meteorites are thought to come from the cores of larger objects, such as asteroids or protoplanets, that have been broken apart by impacts.
c. Some stony meteorites resemble cooled lava. This is true because some stony meteorites, which are made mostly of rock and metal, can have a texture and composition that is similar to cooled lava.
d. Like most meteorites, stony meteorites come from comets and asteroids. This is also true, as stony meteorites, like most meteorites, are believed to come from comets and asteroids.

Identify whether each of the following descriptions are true or false. To sustain fossil fuel resources, alternative sources of energy should be used. Drip irrigation uses more water and is not helpful in sustaining water use. Limiting erosion, disposing of mining waste, and limiting water pollution from the mine helps sustain land use. Deforestation is helpful in sustaining trees.
Trees are felled for wood, waiting to be transported and sold. Deforestation is the clearing of forest land on purpose. Throughout history up to modern times, forests have been destroyed to make room for agriculture and animal grazing, and to obtain wood for fuel, manufacturing, and construction. Forests are one of our most valuable resources on Earth, they provide us with clean air, materials, food and much more.

Is clarity a good indicator of water quality?
Yes, clarity is a good indicator of water quality
The primary determinant of how the public perceives the quality of water is water clarity. Clear water can be a sign that the water is free of sediment and other particles that can affect its quality, but it does not necessarily mean that the water is safe to drink or use.
Clarity can be a good indicator of water quality to some extent, but it is not the only factor that should be considered. Other factors, such as the presence of harmful bacteria, chemicals, or other contaminants, can also impact the quality of the water and should be tested for in order to determine its safety. In general, it's important to use a combination of factors, including clarity, to assess the quality of water.

percentage of clay in the rock at the cretaceous/paleogene boundary differ from that found in the surrounding rocks? group of answer choices
The majority of the earth's crust has relatively little iridium, however it can be found in meteorites. 30% more iridium is present in the clay layer than in the nearby rock.
The majority of clay minerals are white or light in colour, however natural clays come in a variety of hues due to impurities, like a reddish or brownish hue brought on by trace levels of iron oxide. The first ceramic substance is clay. Although iron substitutes for aluminum and magnesium to variable degrees, and significant amounts of potassium, sodium, and calcium are frequently found, clay minerals are primarily made of silica, alumina or magnesia or both, and water. Because it contains minerals necessary for plant growth, clay is a crucial component of soil. Sculpting using clay is another method. Plasticity is one of clay's qualities. This indicates that the clay can be stretched out without tearing or breaking. Since it doesn't need a kiln, air dry clay is ideal for individuals who are just starting out in pottery making.

which seismic wave type causes the most destruction of property during an earthquake?
Both vertical and horizontal ground motions are produced by Rayleigh waves.
These waves can be the most harmful because when they pass, they elevate and lower the land as they move along. An earthquake is a quick movement of geological materials beneath the earth's surface that causes the ground to shake violently or weakly. The tectonic plate border is where earthquakes start. Earthquakes typically result from subsurface rock breaking unexpectedly and rapid movement along a fault. The seismic waves that cause the ground to tremble are brought on by this quick release of energy.

which statement describes the damage that results from earthquakes? amount of damage can be used to determine intensity. damage can be measured using the richter scale. the amount of damage increases
Amount of damage can be used to determine intensity. Intensity is the quantity of energy that kids often utilize to convey their emotions. Some kids have very strong emotional reactions to things from birth. These kids express whatever it is they are experiencing with a lot of vigour and excitement.
The amount of energy a wave transfers over a surface in a unit of time is measured as its intensity, which is also equal to the energy density times the wave speed. The formula for intensity is: intensity = power area. The amount of light that falls on a surface over a specific square foot or square meter is known as light intensity or luminous intensity. Lumens per square foot (foot-candles) or lumens per square meter are units used to measure light intensity (lux). Additionally, it's important to consider how intensely you exercise in addition to how much and what kind of movement you perform. Exercise and physical activity are typically divided into three categories: low, moderate, and high intensity (sometimes called "vigorous"). With waves like acoustic waves (sound) or electromagnetic waves like light or radio waves, intensity is most usually employed to describe the average power transfer across one period of the wave. Other situations where energy is exchanged can also be described in terms of intensity. A quick method to gauge relative intensity is the conversation test. In general, you can converse but not sing while engaging in moderate-intensity exercise. In general, you won't be able to speak for more than a few words without pausing to take a breath if you're engaging in vigorous-intensity activities.
