The Rock Cycle

The process by which water, wind, ice, and changes in temperature break down rock into fragments called sediments.

• deposition
• erosion
• weathering
• compaction

Rock that forms when minerals form from solutions or sediment from older rocks get pressed and cemented together.

• sedimentary rock
• metamorphic rock
• igneous rock

Rock that forms when pressure, temperature, or chemical processes change existing rock.

• igneous rock
• sedimentary rock
• metamorphic rock
• Rock Cycle

The processes by which metamorphic rocks are formed are _?_.

• heat and pressure
• compaction and cementation
• melting and cooling

The processes by which igneous rocks are formed are _?_.

• heat and pressure
• melting and cooling
• compaction and cementation

A metamorphic rock can become _?_.

• igneous

The name rock is given when it is broken down into smaller pieces is _?_.

• texture
• weathering
• sediment
• erosion

What does it mean for a rock to be extrusive?

• have layers
• have rounded edges

The diagrams shows a rock with water trapped in the cracks during the day and at night. Which statement best explains why this process results in weathering?

• frozen water acts as a solute
• water expands when it freezes
