Answer 3

It is the very hot, very dense center of our planet.

Question 4

The solid, outer part of Earth.

Answer 4

Lithosphere

Question 5

Asthenosphere

Answer 5

Weaker layer beneath the lithospheric mantle.

Question 6

Uppermost layer of the oceanic portion of the tectonic plates.

Answer 6

Oceanic crust

Question 7

Is a geologican process in which the oceanic lithosphere is recycled into the earth’s mantle at convergent boundaries.

Answer 7

Subduction zone

Question 8

is a seafloor mountain system formed by plate tectonics.

Answer 8

Mid-ocean ridge

Question 9

Earth’s outer shell is divided into large slabs of solid rocks, called “plates” that glide over Earth’s mantle.
