Core

Is the solid centre of the Earth

1 of 16

Continental Crust

Is made out of Granit Rock. Continental Crust is thick but light crust that has land on top of it.

2 of 16

Oceanic Crust

Is made out of Balsalt Rock. It is thin but VERY heavy crust which is under the oceans.

3 of 16

Convection Currents

Is movment of the semi molten rocks due to the high temperture in the core,

4 of 16

Lithosphere (Lower Mantle)

The Earth’s lithosphere is the rigid outer layer that is made up of the crust and the part of the mantle just below it.

5 of 16

Asthenosphere (Upper Mantle)

Is on top of the Lithosphere (Lower Mantle) closest to the crust.

6 of 16

Mantle

Is full of semi molten rock between the Core and the Crust.

7 of 16

Pangea

At one time all of the Contnents were joined together but when Convection Currents moved them around and at the Plate Boundaries Volcanoes Happened!

8 of 16

Constructive Plate Boundaries

9 of 16

Conservative Plate Boundaries

10 of 16

Destructive Plate Boundaries

11 of 16

Collision Zone

A Collision Zone is a type of Destructive Boundary. They form Mountain Ranges. Two Continental Plates of Low-Density, granite Collide, pushing Up mountains. This is where Earthquakes Happen.

12 of 16

Basalitic Lava (Cow Pat!) Shield Volcanoes, Just Lava!!

Is found on Constructive Margins. It is High Temputer and Very Low in silica, with Low Gas content. This type of lava has LITTLE Explosive Activity.

13 of 16

Andesitic Lava (Cone!) Composite Volcanoes, Layers of Ash and Lava!!

Is found on a Destructive Magins where Continental Rock are melted by rising magma.It is LOw Temperature, has More Silica and a lot of Dissolved Gas. AS a result this is much Less Fluid than Basalilic Lava. And is more likly to Explode

14 of 16

Composite Volcanoes

Is made out up of layers of Ash and Lava. And is on a Destructive Plate Boundaries.

15 of 16

Shield Volcanoes

Is made out of Sticky and runs out and is on a Constructive Plate Boundaries. And is just made out of Lava.
