Question

3 where is the earths crust the thickest?
a
b
c
d

Explanation:

The Earth's continental crust is thicker than oceanic crust, and thickest beneath large mountain ranges due to isostasy—where the crust "floats" on the mantle, building thicker crust under heavy, elevated landforms. Option A shows ocean (thin oceanic crust), Option C points to polar regions (thinner crust than mountains), Option D points to a low-latitude continental area (thinner than mountain zones). Option B depicts a large mountain range, where the crust is thickest.
