Geologists in Egypt and Ethiopia are comparing rock samples from rocks found in the two countries. They are sharing information about the rocks to figure out whether they are the same or different types of rock. The information is as follows:

• Rock A formed from small pieces of rock.

• Rock B formed from liquid rock in a different place.

• Rocks A and B  formed at about the same time.  

Are Rocks A and B the same or different types of rock?

The rocks are:

• the same type because they both formed from rock material.

• the same type because they formed at the same time.

• different types because they formed in different ways.

• different types because they formed in different places.

What rocks are also known as 'magma rocks' ?

• Sedimentary Rocks

• Metamorphic Rocks

• Igneous Rocks

Which type of rocks have layers?

• Sedimentary Rocks
