Rock Types and Their Formation

What is the primary process responsible for the formation of igneous rocks?

• Stratification

• Accumulation of marine organisms

• Solidification of magma

• Erosion

Which of the following is a characteristic feature of sedimentary rocks?

• Presence of fossils

• Formation from magma

• Deformation under pressure

• High temperature formation

How is limestone primarily formed?

• From solidified lava

• By accumulation of marine organisms

• Through high pressure and temperature

• By the cooling of magma

What distinguishes metamorphic rocks from igneous rocks?

• Metamorphic rocks form from liquid material

• Metamorphic rocks form under high pressure and temperature without melting

• Metamorphic rocks contain fossils

• Metamorphic rocks are formed by erosion

What does the rock cycle illustrate?

• The immediate formation of rocks

• The transformation of rocks over geological time

• The exclusive formation of igneous rocks

• The process of fossilization
