Types of rocks

Convergence is the plate tectonic movement caused by the convection currents. Choose the options that describes the movement of the convection currents in the mantle:

• Plates move away of each other

• Plates slide past each other

• Plates move towards each other

• Plates move skipping each other.

What are the converging plate boundaries?

• Is the place where plate tectonics are thinner.

• Is the edge of collision between two tectonic plates.

Subduction refers to:

• When two tectonic plates met and then mountains are formed.

• When two tectonic plates push against each other, as they have the same density, one does not slide on top of the other instead.

• When Is one plate is denser than the other, so the denser plate slides on top of the less dense plate.

In the __________ If both plates have the same density they push and push against each other, as they have the same

density, one does not slide on top of the other instead

the sides the plates are touching move up.

TRUE OR FALSE.

The mixed of one or two minerals together, influenced by processes of heating, melting and so on, made up the rocks.

• FALSE

• TRUE

The tree types of rocks are:

• Igneous rocks

• Sedimentary rocks

• Metamorphic rocks

• Intrusive and extrusive rocks

These types of rocks are formed when magma cools down at or close to earth’s surface and forms crystals.

• Igneous rocks

• Sedimentary rocks

• Metamorphic rocks

These rocks are formed inside the Earth’s crust crystal form slowly as the magma cools down slowly over a longer period of time

• Intrusive rocks

• Extrusive rocks

• Metamorphic rocks

• Sedimentary rocks

These rocks are form on the Earth’s crust. The rock is erupted out of a volcano and cools down quickly when it comes into contact with cold air.

• Intrusive rocks

• Extrusive rocks

• Metamorphic rocks

• Sedimentary rocks

These rocks are formed by weather and erosion. The sun shines on them and they expand get bigger when it gets hot and contract get smaller when it cools down.

• Igneous rocks

• Sedimentary rocks

• Metamorphic rocks

• Intrusive and extrusive rocks
