The Rock Cycle Quiz

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

• Igneous, Metamorphic, Sedimentary

• Granite, Basalt, Limestone

• Obsidian, Gneiss, Sandstone

• Marble, Coal, Pumice

How are sedimentary rocks formed?

• By chemical precipitation

• From pieces of other existing rock or organic material

• By immense heat or pressure

• By cooling and solidifying of molten material

What is the process of weathering in the formation of sedimentary rocks?

• Breaking down of exposed rock into small fragments

• Chemical precipitation of dissolved minerals

• Formation of solid rock from compacted sediment

• Transportation of sediment by wind, water, ice, or biological activity

What are the two classes of metamorphic rocks?

• Vesicular and Holey

• Intrusive and Extrusive

• Foliated and Nonfoliated

• Clastic and Organic

What happens to minerals in foliated metamorphic rocks under immense pressure?

• They align in layers, creating foliation

• They shift to all point in the same direction

• They turn into volcanic glass

• They form from chemical precipitation

How are extrusive igneous rocks formed?

• By immense heat or pressure

• Outside or on top of Earth’s crust

• By cooling and solidifying of molten material

• Inside of the earth

What is the texture of intrusive igneous rocks like granite and diorite?

• Very small grains and fine texture

• Holey texture with gas bubbles

• Coarse texture with large mineral grains

• Aligned elongated or platy minerals

What happens when magma erupts into lava and cools quickly?

• It forms chemical precipitates

• It turns into volcanic glass

• It aligns elongated or platy minerals

• It traps gas bubbles giving a bubbly texture

What is the process of erosion in the formation of sedimentary rocks?

• Breaking down of exposed rock into small fragments

• Formation of solid rock from compacted sediment

• Chemical precipitation of dissolved minerals

• Transportation of sediment by wind, water, ice, or biological activity

What are nonfoliated metamorphic rocks formed from?

• Magma coming in contact with the surrounding rock

• Long and platy minerals shifting under pressure

• Clastic and organic materials

• Bituminous coal, limestone, and sandstone
