Rock Cycle Quiz

What are the three main types of rocks involved in the rock cycle?

• Sedimentary, Metamorphic, Volcanic

• Igneous, Volcanic, Sedimentary

• Igneous, Sedimentary, Metamorphic

• Metamorphic, Igneous, Fossil

How are igneous rocks formed?

• By the accumulation of sediments

• By the evaporation of seawater

• By the cooling and solidification of magma or lava

• By the transformation of existing rocks under pressure

What process turns igneous rocks into sediments?

• Metamorphism

• Cementation

• Weathering

• Melting

What distinguishes intrusive igneous rocks from extrusive ones?

• Intrusive rocks form on the Earth's surface, extrusive rocks form underground

• Intrusive rocks have large crystals, extrusive rocks have small crystals

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

• Intrusive rocks are glassy, extrusive rocks are grainy

Which of the following is an example of an extrusive igneous rock?

• Granite

• Diorite

• Basalt

• Gabbro

How are sedimentary rocks typically formed?

• By the cooling of magma

• By the accumulation and cementation of sediments

• By the recrystallization of minerals

• By the melting of existing rocks

Which type of sedimentary rock is formed from the remains of plants and animals?

• Plastic

• Organic

• Chemical

• Igneous

What causes metamorphic rocks to form?

• Accumulation of sediments

• Cooling of lava

• Evaporation of seawater

• Heat and pressure

Which of the following is a foliated metamorphic rock?

• Obsidian

• Slate

• Limestone

• Marble

What is the main difference between foliated and non-foliated metamorphic rocks?

• Foliated rocks have a banded appearance, non-foliated rocks have a uniform texture

• Foliated rocks are glassy, non-foliated rocks are grainy

• Foliated rocks are formed from lava, non-foliated rocks from magma

• Foliated rocks have a uniform texture, non-foliated rocks have a banded texture
