What processes contribute to the transformation of rocks in the rock cycle?

• Weathering and erosion

• Melting and cooling

• Compaction and cementation

• All of the above

What do all rock types have in common?

• They are all made of minerals.

• They all contain fossils.

• They are all formed by volcanic activity.

• They all have the same color.

How are igneous rocks formed?

What is the difference between intrusive and extrusive igneous rocks?

• Intrusive rocks form below the Earth's surface, while extrusive rocks form on the surface.

• Intrusive rocks are formed from lava, while extrusive rocks are formed from magma.

• Intrusive rocks are always denser than extrusive rocks.

• Intrusive rocks are lighter in color compared to extrusive rocks.

What determines the crystal size of igneous rocks?

• The rate of cooling of the magma or lava

• The color of the minerals present

• The location where the rock is found

• The type of eruption that formed the rock

Felsic and mafic igneous rocks are types of igneous rocks. How do they differ?

• Felsic rocks are rich in silica and light in color, while mafic rocks are rich in magnesium and iron and dark in color.

• Felsic rocks are rich in magnesium and iron and dark in color, while mafic rocks are rich in silica and light in color.

• Both felsic and mafic rocks are rich in silica and light in color.

• Both felsic and mafic rocks are rich in magnesium and iron and dark in color.

An example of an intrusive igneous rock is granite, and an example of an extrusive igneous rock is:

• Basalt

• Marble

• Slate

• Sandstone
