<span>The Greenhouse Effect:
The greenhouse effect is a natural phenomenon, which, helps maintain the
relatively stable, livable, range of temperatures that we find on
earth. To better understand how this phenomenon works, scientists have
used the analogy of the greenhouse. In a greenhouse, the glass (the
atmosphere) allows the radiant energy (light) of the sun to enter. As
the radiant energy strikes various plants, gases, and objects in the
greenhouse, they heat up. Their heat is then released back into the air
of the greenhouse as infrared radiation (heat). This infrared radiation
cannot travel through the glass and remains inside the greenhouse,
increasing the temperature inside the greenhouse. Temperatures can be
controlled, or kept in balance, by allowing some of the heat to remain
inside and some to be vented to the outside. Under normal conditions,
the earth's atmosphere works in a similar manner. Solar radiation enters
the atmosphere and heats up the air molecules, the surface of the
earth, buildings, plants, and other objects. These objects in turn,
radiate infrared radiation back out into the atmosphere, where some of
this radiation is absorbed by the greenhouse gases, and some is radiated
out into space. As some of the heat stays in the atmosphere and some
escapes into spaces, a balance is maintained allowing our planet to have
a relatively stable range of temperatures. Scientists believe that as
the greenhouse gases become more abundant in the atmosphere, due mainly
to the burning of fossil fuels, they retain more and more infrared
radiation, allowing less and less to escape into space, tipping the
balance toward heating up the atmosphere, resulting in a changing and
warmer climate, planet-wide. This is the accelerated greenhouse effect.

Answer:
c. close to the Earth's surface
Explanation:
The rocks that form from the cooling magma or lava flows are the igneous rocks. When it comes to their texture they can roughly be divided into two major groups, fine-grained and coarse-grained, further having several sub-divisions as well.
The fine-grained igneous rocks are the ones that are formed either on the surface or very close to the surface. Because the temperature and pressure at this parts is much lower, the magma or the lava cool off very quickly. Because of the rapid cooling off, there is simply not enough time for the crystals to grow larger, so they are very small, often can not even be seen with naked eye.

Answer:
Glacier Deposits
Coastal Deposits
Rivers
Explanation:
These are all depositional landforms.
Glacier Deposits:
When a glacier moves over a landscape, it picks up and carries with it rocks, soil and other forms of rubble. When the glacier retreats, the rubble contained within it is left behind in the new landscape.
Coastal Deposits:
Waves transport materials such as sand, rocks, shells and dirt and drop them to form both underwater and above-surface landforms.
Beaches are made up largely of sediment deposited there by waves. These types of coastlines are an example of depositional landforms that change rapidly as existing sediment is eroded and new sediment deposited.
Waves can also deposit sediment in areas offshore, where they build up to be sandbars and sand dunes. This buildup usually occurs when waves crash in shallow waters and draw some of the sediment from the bottom back out toward the ocean.
Rivers:
Rivers can also carry sediment downstream to deposit it when the water enters into a larger body of water.
