The picture shows a diagram of Earth's layers.

What is happening at point W?

A. Magma in the mantle is being heated by the hot core, causing it to rise toward the crust, then sink as it cools, the convection circuit pulling the tectonic plates.

B. Water in the mantle is being heated by the hot crust, which causes it to sink toward the core where it cools, the convection circuit pulling the tectonic plates.

C. Energy from the Sun heats the crust, which conducts heat into the mantle, causing the magma to warm and sink toward the core, pulling the tectonic plates.

D. Energy from the Sun heats the crust, causing it to shift and pull the tectonic plates, which uses friction to heat the magma in the mantle.

Answer:

It is A. Magma in the mantle is being heated by the hot core, causing it to rise toward the crust, then sink as it cools, the convection circuit pulling the tectonic plates.

Why does the Earth spin faster at the equator than the poles?

a
Due to the temperature differences on Earth, the land/sea near the equator goes at a faster rate. The Earth spins faster there only during the summer months.
b
The Earth is much wider at the equator than at the poles. It must cover a larger distance in the same amount of time (24 hours).
c
Due to the tilt of the Earth on its axis, the equator gets more sunlight -- therefore making it spin faster.
