s=ut
s1=5.8*(12.9*60)
s1=4489.2m
s2=6.1*(7.1*60)
s2=2598.6m
so, total distance = s1+s2 =7087.8m
The folding of the Earth's crust could change the plant species that can survive in a location.
Explanation:
The movement of the tectonic plates is one of the primary factors that influence the creation and destruction of habitats. This is because this motion is able to change the landscape, create new crust, destroy old crust, lift or lower and area etc. When two plates collide, one feature that always occurs are the mountains, or highlands in general.
If an area was a lowland, and it gradually became a mountainous area, that will have big affect on the biosphere. The climate will be changed, the elevation too, the steepness of the terrain, the insulation and albedo etc. All of this will result in either adaptation of the plants to live in the changed conditions or spreading of plants that are already adapted for those kind of conditions. With the change of the plants there will be change of the species of animals, so over time the biosphere will be totally changed.
Answer:
A) sea level drops; land subsides
Explanation:
The sea is the final destination of all streams on land. All streams empty into seas which are the basins that collects all terrestrial materials.
The base level is the lowest level to which a river can erode its channel. The base level is greatly influenced by what happens to a sea.
When a river reaches its base level, erosion ceases. If a river is young and set above its base level, we see a rapid rate of erosion.
A sea, the final basin of depostion of rivers controls the base level to a very large extent. When there is a tectonic movement and a sea subsides. It becomes more deeper and lower. Sea level also falls and materials grades seaward. A river would cut rapidly along its channel and its bed to measure up to the level of the ocean.
Therefore, we see a very rapid rate of erosion of channels when sea level falls and the earth sags downward. This would lead to a lower base level.
When sea level rises and there is a tectonic uplift, rivers erode their channels less and begins to aggrade materials. The base level also rises.
Answer:
they produce little waste
