Layers of Earth

Continents

Tectonic boundary

Tectonic plates

The movement of the tectonic plates is called plate tectonics. 

Places where two plates meet are called plate boundaries. 

What isn't a direct consequence of plate tectonics?

1. Tsunami
2. Earthquake
3. Hurricane
4. Volcanic eruption

What is the driving force behind plate tectonics?

1. Convectioncurrents
2. Sea
3. Mantle
4. Lava

Convection current

=  the flow of molten rock under the earths crust.

Put the descriptions in the right place

Mantle

Magma

Plates

Core

Convection current

Lava

Thick layer under the earth's crust, consisting of hot rock.

Hot, liquid rock in the Earth's mantle. The same as lava, but underground.

Pieces of crust on which the continents and oceans lie.

Earth's interior: a large iron ball of more than five thousand degrees Celsius.

The driving force behind plate tectonics: warm magma rises, hits the earth's crust and flows sideways.

Liquid rock that comes out of the earth.

How do we call this type of tectonic movement?

1. Subduction
2. Divergent
3. Convergent
4. Transform
