Answer:
When the sun shines on earth, the sunlight warms up the earth, in the way that sunlight would warm up a greenhouse. At night, when there is no sunlight, the earth cools down, just like a greenhouse. When cooling down, the earth keeps some of the warmth trapped in the atmosphere- just like how a greenhouse would.
Answer:
<u>Yes , They are architectural structures that shape the geology of earth.</u>
Explanation:
- These geologic structures influence the shape and size of landscape development and determine the degrees to landscape hazards. Folds and faults and other geologic structures accommodate large forces/stress on earth's tectonic plates.
- Foldes are of two types such as Syncline and Anticline. Formed due to the crustal bending and wrapping of the geo sediments or rocks. The youngest at the top and the oldest at the bottom. As antiforms contain comparatively younger folded rock strata.
- Faults are a planar surface within the earth, where the rocks have slid or broken a fault may be caused due to the elastic strains on the rocks, the rocks on either side are shifted in opposite direction and the faults get induced.
- There are many types of faults and folds in the history of the earth's surface, many of these have led to the formation or shaping of mountain ranges and various mountain chains.
- Another example can be of Mount Everest which is a young folded mountain formed from the colloid of the Tethys sea when India was once a part of the Australian continent.
- Plate tectonics is thus directly related to the formation and motion of the plates which mover the entire planet and shape its orogeny

C. andesite. hope this helped!
Answer:
Density is one of the most factors that play a key role in plate tectonic activities. Some of the ways in which density is important in the field of plate tectonics are as follows-
- The convergent plate boundaries are responsible for the creation of a subduction zone, where the high-density lithospheric plate subducts below the less dense one. It is because the heavier plate is comprised of heavy minerals thereby forming heavier rocks as a result of which its density increases. Due to these differences in density, there occurs a subduction zone.
- The divergent plate boundary forms where two plates move away from one another. This type of plate motion is responsible for the eruption of magma on the seafloor. As the plates diverge, the lithosphere becomes eventually thin, and with more progressive spreading, the magma comes out to the seafloor. This is because the hot magma is less dense, and forms convection cells as they rise upward. This is how the density helps in the upwelling of magma at the mid-oceanic ridge in a divergent plate boundary.
- When there collide two plates of equal densities, then it gives rise to the formation of huge mountains, because neither of them is heavy to get sink. So it uplifts the crust, forming a sandwich-type pattern.
