Introducing Rock Cycle

Occurs when rock particles or sediments are pressed together or packed down by gravity and the pressure of overlying rock layers.

• Compaction
• Ocean trench
• Rock cycle
• Plate tectonic theory
• Earth's evolution

Occurs when compacted sediments stick together and turn into rock.

• Cementation
• Magma
• Volcanic eruption
• Metamorphic rock
• Compaction

The process by which gravity, water, wind, and ice deposit weathered and relocated sediment.

• Deposition
• Sedimentary rock
• Ocean trench
• Magma
• Erosion

The process by which water, ice, wind, and gravity remove and transport sediment from one place to another.

• Erosion

• Heat and pressure

• Igneous rock

• Mineral composition

• Sedimentary rock

Changing variables due to the weight of overlying rocks, causing changes to rock characteristics and mineral composition, thus forming metamorphic rocks.

• Heat and pressure
• Volcanic eruption
• Earth's evolution
• Compaction
• Sedimentary rock

Formed when lava or magma cools and solidifies. Lava cools quickly and forms rocks with small crystals, while magma cools more slowly and forms rocks with larger crystals.

Metamorphic rock is formed deep underground where heat and pressure cause existing rocks to be changed in both mineral composition and structural characteristics.

• Metamorphic rock
• Weathering
• Sedimentary rock
• Volcanic eruption
• Mineral composition

Earth's rocks change from one type into another over time due to various Earth processes. Changes occur in mineral compositions and physical structures.

• Rock cycle
• Igneous rock
• Mineral composition
• Sedimentary rock
• Weathering

Forms when particles of other rocks are deposited in layers and are compacted (crushed together), and cemented (binding of the sediments).

The mechanical or chemical processes that break rocks into smaller pieces, and sometimes change the chemical composition.
