EES Geology RockCycle & RockVocab

What are the 3 major types of rocks?

• Igneous, Metamorphic, Sedimentary
• Metamorphic, Igneous, Cementation
• Brown, Red, Gray
• Streak, Hardness, Breakage

The three groups of rocks are classified by

• How they form
• Color
• Grain size
• Chemical Composition

A rock deep within the Earth experiences extreme temperature and pressure. After a long period of time it becomes which rock? Assume it does not melt.

• Magma

• Igneous

• Metamorphic

• Sedimentary

What must happen to a metamorphic rock before it becomes a sedimentary rock?

• It must be broken down into sediment

• It must be melted into magma

• Its minerals must dissolve in water

• It must be exposed to high temperature and pressure

What process is used to form sedimentary rocks?

• Lava cools and hardens to form a rock.
• Weathering, Erosion, Deposition, Compaction, Cementation
• Extreme heat and pressure from inside the Earth turn rocks into new rocks.
• Magma trapped under the Earth's surface cools and solidifies.

Which of the words below describe broken up rock?

• stalactites
• magmas
• metamorphs
• sediments

This rock was formed by smaller pieces of rock that settled at the bottom of a lake millions of years ago. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic

The process in which sediment are fused or glued together.

• compaction
• deposition
• organic rock
• cementation

What is deposition?

• Dropping off sediment
• Movement of sediment
• Breaking down of sediment 

The process when rocks break into smaller pieces due to exposure to natural elements is called

• erosion
• weathering
• sediments
• deposition
