Layers of the Earth
What is the thinnest layer of the Earth?
The Crust
The diagram shows the location of volcanoes all around the world. Based on the diagram describe where volcanoes are MOST LIKELY to form?
Volcanoes form where tectonic plates meet other plates
What are most rocks made of?
Minerals
Identify the thickest layer of the Earth
The Mantle
Which type of boundary dose the diagram illustrate?
Convergent Boundary
What process will change sedimentary rock into an igneous rock?
Melting and Crystallization
Which layer of the Earth has the greatest Pressure and density?
Inner Core
Plate tectonics describes movements mainly in which layer of the Earth?
Earth's Crust
Identify the layer which is solid but capable of flow
Mantle
Explain how convection currents cause the Earth's Crust To move.
The Mantle is made of hot material that rises to the top, cools, then sinks, and continually repeats the cycle
Why is the Inner Core solid?
The pressure from the Outer Core, Mantle, and Crust compresses it tremendously
Where Do most geologic events take place?
The boundary of tectonic plates
