Science Review: Earth Layers and Volcanoes

​Layers of the Earth

• ​Crust

  • ​Continental Crust

  • ​Oceanic Crust

• ​Mantle

• ​Outer Core

• ​Inner Core

​Crust

​We live on the crust.

​

​There is the oceanic crust

​

​And continental crust

Multiple Choice

We live on the first layer of the Earth.

Multiple Choice

Which picture shows the crust where all living things on Earth Are found.

Multiple Choice

Which picture shows the Oceanic Crust

Multiple Choice

The continental crust is where the land is.

​Mantle

​The next layer is called the mantle.

​

​It is thicker than the crust.

​

​Made of many minerals.

​

​It is soft like play-doh.

​

​Tectonic Plates can be found here.

Multiple Choice

Mantle:  The layer under the crust.

​Tectonic Plates

​Tectonic plates move around slowly.

​

​When they do, big things happen on Earth

Multiple Choice

Tectonic Plates:  2 plates that floats on the mantle.

Multiple Select

When tectonic plates crash they can create:

​Fault Line

​Where 2 tectonic plates meet, is called a FAULT line.

​How are volcanoes made?

​Mantle plumes will form in super heated areas in the mantle.

​

​When it gets really hot...hot rock and magma will push their way out and cause an eruption.

​Types of Volcanoes

​Active volcano is either erupting, showing signs of eruption, or recently erupted.

​Types of Volcanoes

​Dormant volcanoes are ones that have erupted in recent history but are quiet now. Scientists believe these volcanoes may erupt again.

​Types of Volcanoes

​Extinct volcanoes have not erupted in a long time, and scientists believe they will never erupt again.

Multiple Select

There are 3 types of volcanoes:
