1. What layers of Earth make up the lithosphere?

Jobisdone [24]

<span>Answer 1: The correct answer is the crust and the upper mantle.

The lithosphere refers to a solid, rocky part of the Earth, that is the Earth's outermost layer. It is comprised of the crust and upper mantle (refer to attached image). The lithosphere is around 100 km deep.

Answer 2: The correct answer is its crust.

The Earth's crust refers to the outermost rocky shell of the Earth where organisms live (refer to second image). The crust is made of solid rocks, including igneous, sedimentary and metamorphic rocks. The Earth's crust is around 30 km deep.

Answer 3: The correct answer is iron and nickel.<span>

The Earth's core refers to the innermost or central part of the Earth. It lies around 2900 km beneath the Earth's surface and is spherical in shape. The Earth's core is comprised of an alloy (mixture) of the metals iron and zinc.It is made of two layers: the outer core and the inner core. </span></span>

Choose the most correct scenario for a sunny summer afternoon at a parking lot.

vitfil [10]

Answer:

D. Solar radiation heats the asphalt; the air immediately above is heated through conduction; the warm air rises in free convection.

Explanation:

As the parking lot is exposed to the sun, on a sunny afternoon, we can consider that the sun is radiating with high intensity in this environment, causing the asphalt to be strongly heated. In this case, the air that comes in contact with the asphalt ends up being heated, because the heat of the asphalt is transmitted by the air through the process called conduction, which is the heat transmitted by the agitation of the molecules.

The heated air becomes less dense, that is, it becomes lighter and this causes it to rise, while the cold air is more dense and descends, coming into contact with hot asphalt and also heating up. In that case, a heat transfer called convection occurred.

Knox County is able to draw fresh water from the Lewis and Clark Lake over and over. Describe the possible interactions of Earth

Naddika [18.5K]

Answer:

Erosion has exposed limestone, shale and sandstone geology of the area in the scenic cliffs along the shore of Lewis and Clark Lake SRA, a reservoir on the Missouri River in Knox and Cedar counties.

Environmental science studies the interactions between the physical, chemical, and biological components of the environment, including their effects on all types of organisms. Earth science (also known as geoscience), is an inclusive term for all sciences related to Earth (geology, meteorology, oceanography, etc). Although environmental and earth science cover essentially the same material, environmental science places greater emphasis on the biological realm, while earth science places greater emphasis on the physical realm.

The four spheres are the geosphere (all the rock on Earth), hydrosphere (all the water on Earth), atmosphere (all the gases surrounding Earth), and biosphere (all the living things on Earth).

The spheres interact to effect Earth’s systems and processes, and they are constantly changing each other.

For example, ocean currents (hydrosphere) affect air temperature (atmosphere): The Gulf Stream is a powerful water current in the Atlantic Ocean. It’s warm water moderates the temperatures on the east coast of the USA.

Another example of how the spheres affect each other is through erosion. Erosion happens in the desert when wind (atmosphere) shapes the sand in the geosphere. Water (hydrosphere) can also shape land, such as in the formation of the Grand Canyon.

Explanation:

Lakes and wetlands also have distinctive biogeochemical characteristics with respect to their interaction with ground water. The chemistry of ground water and the direction and magnitude of exchange with surface water significantly affect the input of dissolved chemicals to lakes and wetlands. In general, if lakes and wetlands have little interaction with streams or with ground water, input of dissolved chemicals is mostly from precipitation; therefore, the input of chemicals is minimal. Lakes and wetlands that have a considerable amount of ground-water inflow generally have large inputs of dissolved chemicals. In cases where the input of dissolved nutrients such as phosphorus and nitrogen exceeds the output, primary production by algae and wetland plants is large. When this large amount of plant material dies, oxygen is used in the process of decomposition. In some cases the loss of oxygen from lake water can be large enough to kill fish and other aquatic organisms.

The magnitude of surface-water inflow and outflow also affects the retention of nutrients in wetlands. If lakes or wetlands have no stream outflow, retention of chemicals is high. The tendency to retain nutrients usually is less in wetlands that are flushed substantially by throughflow of surface water. In general, as surface-water inputs increase, wetlands vary from those that strongly retain nutrients to those that both import and export large amounts of nutrients. Furthermore, wetlands commonly have a significant role in altering the chemical form of dissolved constituents. For example, wetlands that have throughflow of surface water tend to retain the chemically oxidized forms and release the chemically reduced forms of metals and nutrients

Which of the following lithospheric plates is not included among the seven largest

kompoz [17]

Answer:

Yes? The Philippine plate is not included among the seven largest lithospheric plates.

Explanation:

It is not included, but it is a very large lithospheric plate. (I don't understand how this is a question, but, it's correct)
