What caused the 36,160 ft deep Marianas Trench to form?

excessive boat traffic, two tectonic plates creating a subduction zone

What does Pangaea mean?

It is the name of an ancient supercontinent.

Why is the Earth's inner core solid even thought it is much hotter than the liquid outer core?

The pressure from Earth's layers keeps it in a solid state.

Which of the following does not support the theory of continental drift?

The North Pole and Antarctica are covered in ice.

The cycle of hot material rising to the top of the mantle, cooling, sinking, and repeating is

is known as convection currents.
