Earth's Processes Recap #1

Breaking of a mineral along a smooth flat surface

• fracture

• cleavage

• cementation

• abrasion

Circulation of particles within a material caused by differences in thermal energy and density

• convection

• radiation

• conduction

breaking of a mineral along a rough or irregular surface

• cleavage

• fracture

• compaction

• intrusion

Igneous rock that forms as magma cools underground

• intrusive

• extrusive

• foliated

• nonfoliated

Mechanical and chemical processes that change Earth's surface over time

• weathering

• erosion

• deposition

• compaction

moving of weathered material or sediment from one location to another

• Weathering

• erosion

• deposition

• compaction

Laying down, dropping, settling of eroded material

• weathering

• erosion

• deposition

• compaction

physical processes that naturally break rocks into smaller pieces

• physical weathering

• chemical weathering

• mechanical weathering

Features of the surface of the Earth such as mountains, hills, dunes, oceans, and rivers are called

• delta
• erosion
• landforms

How do glaciers change land?

• They can wear away mountains and leave behind valleys.

• They stop erosion of land by blocking rivers and streams.

• They warm up the area so that animals can live.

• They move very quickly and break everything in their path.
