Plate Tectonics

Question 0

Convergent

Answer 0

Colliding tectonic plates

They create mountains & trenches

Question 1

Plate tectonic theory

Answer 1

The earths lithosphere is broken up into sections or pieces called plates-also called lithosphere plates or tectonic plates. The movement produces major changes in atmosphere

Question 2

Transform

Answer 2

Collide by sliding past each other.

They create earthquakes and faults

Question 3

Divergent

Answer 3

Seperate from each other.

Creates ridges & , volcanoes

Question 4

Convection cells

Answer 4

When the mantle rocks rise towards the crust, they cool off and become denser than the rocks below. Therefore they sink towards earths hot center and the cycle of convection continues

Question 5

Convection cells

Answer 5

A convection cell is a system in which a fluid is warmed, loses density and is forced into a region of greater density

Question 6

Volcanoes

Answer 6

Volcanoes can occur along both convergent and divergent plate boundaries. Along convergent ones, they occur as the two plates collide together and one subducts under the other. They can also happen along divergent plate boundaries

Question 7

Hotspots

Answer 7

An area of intense heat, radiation, or activity

Volcanoes are on hotspots
