6.10C Assessment Items

Metamorphic rocks are different from igneous and sedimentary rocks in that metamorphic rocks form–

• By magma rising from Earth’s core

• Small rocks becoming cemented together

• Solid rock changing under pressure

• By layering minerals of different sizes

Igneous rocks and Metamorphic rocks have similar formation in that they both–

• Require extreme heat

• Always form from sediments

• Cool to form distinct layers

• Often contain fossil organisms

Scientists classify igneous, metamorphic, and sedimentary rocks based on their—

• Shape

• Color

• Formation

• Usefulness

What geologic process changes pieces of rocks, minerals, and other material into sedimentary rock?

• A. Compacting and cementing

• B. Cooling

• C. Heat and pressure

• D. Melting

Identify the series of geologic processes that can transform sediment into shale, shale into slate, and slate into magma.

• Cooling; melting; heat and pressure

• Compacting and cementing; heat and pressure; melting

• Melting; heat and pressure; cooling

• Weathering and erosion; compacting and cementing; cooling

Which of the following are part of the final processes in the formation of sedimentary rock? Choose TWO that apply.

• A) Melting

• B) Cementation

• C) Heat

• D) Compaction

• E) Cooling

Drag and drop the term to match with the correct definition.

• Rocks that are formed when superheated magma or lava cools and hardens.

• Igneous Rock

• Rocks that are formed deep underground while under extreme temperature and pressure.

• Metamorphic Rock

• Rocks formed by the process deposition, compaction and cementation.

• Sedimentary Rock

What type of rock is formed from cooling and solidification of magma?

Fill in the blank: Sedimentary rocks are formed through the process of _______ and cementation.

• compaction
