Which term describes the movement of sediment from one place to another?

• Deposition

• Erosion

• Cementation

• Crystallization

What is magma?

• Solid rock found on Earth's surface

• Molten rock beneath Earth's surface

• Rock fragments carried by wind

• Layers of sediment

Which rock type is formed by the compaction and cementation of sediments?

• Igneous rock

• Sedimentary rock

• Metamorphic rock

• Obsidian

What is the main process that transforms sedimentary rock into metamorphic rock?

• Melting

• Weathering

• Heat and pressure

• Erosion

Which of the following best describes sediment?

• Molten rock

• Solidified lava

• Small pieces of rock, minerals, or organic material

• Crystals formed from cooling magma

Which process is responsible for the breakdown of rocks without changing their chemical composition?

• Chemical weathering

• Physical weathering

• Melting

• Lithification

What is the correct sequence of processes that leads to the formation of sedimentary rock?

• Melting, cooling, compaction

• Weathering, erosion, deposition, compaction, cementation

• Heat, pressure, melting

• Cooling, crystallization, weathering

How does magma contribute to the rock cycle?

• It forms sedimentary rocks directly

• It cools and solidifies to form igneous rocks

• It causes weathering of rocks

• It erodes existing rocks
