What is the movement of material in a sinking zone?

Answer and explanation

Correct answer: From the surface downward, towards Earth's interior

In a sinking zone, cooler and relatively denser material moves downward from the surface towards Earth’s interior as part of a convection current. Therefore, option A is correct. Option B describes an ascending convection current, which is the opposite of a sinking zone. Exam tip: in a convection cell, cool dense material sinks, whereas warm lighter material rises.
