ES 5 - Rocks - Bradshaw

Which process forms igneous rock?

• Compaction and cementation

• Cooling and solidification of magma

• Heat and pressure

• Weathering and erosion

What is the primary difference between intrusive and extrusive igneous rocks?

• Intrusive rocks cool faster than extrusive rocks

• Extrusive rocks contain larger crystals than intrusive rocks

• Intrusive rocks cool beneath Earth's surface, while extrusive rocks cool on the surface

• Intrusive rocks contain fossils, while extrusive rocks do not

What is the primary process that leads to the formation of sedimentary rocks?

• Melting and cooling

• Weathering, erosion, and deposition

• Heat and pressure

• Volcanic activity

Which of the following is an example of a foliated metamorphic rock?

• Marble

• Quartzite

• Slate

• Limestone

Which rock type is formed by heat and pressure?

• Igneous

• Sedimentary

• Metamorphic

• Fossiliferous

What happens during the process of deposition?

• Rocks are broken down by wind and water

• Sediments are carried away by water or wind

• Sediments settle out and are left in a new location

• Rock is melted by underground magma

Which type of sedimentary rock is formed from rock fragments?

• Clastic

• Chemical

• Organic

• Biochemical

What is the role of plate tectonics in the rock cycle?

• It prevents rocks from transforming

• It plays no role in the rock cycle

• It moves rocks, exposing them to conditions that lead to transformation

• It turns all rocks into metamorphic rock

How does cooling rate affect crystal size in igneous rocks?

• Slower cooling results in smaller crystals

• Faster cooling results in larger crystals

• Faster cooling results in smaller crystals

• Cooling rate does not affect crystal size

What are the three major types of rocks?

• Volcanic, sedimentary, clastic

• Igneous, sedimentary, metamorphic

• Fossiliferous, intrusive, extrusive

• Organic, crystalline, foliated
