Why is earth's crust rigid? give details.
u sooo much if you answer!

(also, i put this under biology because i don't know what it goes under)

The Earth's crust really isn't rigid. The lithosphere is the rigid part of the Earth. The crust and the upper part of the mantle makes up the lithosphere(brittle rock)

Basaltic rocks of the ocean plates are much denser and heavier than the granitic rock of the continental plates. Because of this the continents ride on the denser oceanic plates. The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere .

Yes they are correct good day

3. is true i think i should be right
