1. The answer is B. the asthenosphere
Asthenosphere is a layer of the Earth situated below the lithosphere. It is a semi-fluid and ductile rock or partly molten rock. Due to semi-fluid state of asthenospheric rock, it behave like a plastic and flow gradually. Thus, causes movement of continents.
2. The answer is C. collision between tectonic plates
The Earth’s crust becomes unstable when tectonic plates meet. As the plates slide past each other and push against each other. This causes earthquakes and volcanic eruptions at the edge between the plates.
Structural, frictional, cyclical, and seasonal
Answer:
the ratio of resolution will be 
Explanation:
We have given the diameter of Telescope A is 1 meter
And diameter of telescope B is 6 meter
We know that resolution of telescope is inversely proportional to diameter of the telescope
So 
We have to find the ratio of resolution of B to A
So 
So the ratio of resolution will be
The angle of the Earth on its axis causing the sun to beam on the Northern and Southern Hemispheres differently.
A climate like a desert because, there is less water and it is too hot to live in.
