Question

1. what layer of the earth is known as the thinnest layer?

c. outer core

b. mantle

a. crust

d. inner core

rewatch

Explanation:

To determine the thinnest layer of the Earth, we analyze the Earth's layers: the crust, mantle, outer core, and inner core. The crust is the outermost layer and is much thinner compared to the mantle (which is thick and makes up a large portion of the Earth's volume) and the core layers (both outer and inner core are substantial in thickness). So the thinnest layer is the crust.

Answer:

a. crust
