Vocabulary Week 20

Erosion

• The process by which wind, water, ice, or gravity transports soil and sediment from one location to another.

• The process of breaking down rocks into smaller pieces.

• The movement of tectonic plates beneath the Earth's surface.

• The formation of new soil from organic matter.

Sedimentary Rock

• A type of rock that forms from volcanic activity.

• A type of rock that forms when particles from other rocks or the remains of plants and animals are pressed and cemented together.

• A type of rock that is formed under extreme heat and pressure.

• A type of rock that is formed from the cooling and solidification of magma.

Uplift

• The process of erosion of the Earth's surface.

• The rising of regions of the Earth's crust to higher elevations.

• The movement of tectonic plates causing earthquakes.

• The formation of valleys and lowlands.

rift zone

• An area where tectonic plates collide and create mountains.

• An area of deep cracks that forms between two tectonic plates that are pulling away from each other.

• A region where tectonic plates slide past each other without significant vertical movement.

• An area of volcanic activity caused by tectonic plate movement.

deposition

• The process in which sediment is laid down in new locations.

• The process of eroding rocks and soil.

• The process of water evaporating from the surface.

• The process of plants absorbing nutrients from the soil.

Igneous Rock

• Rock that forms when magma cools and solidifies.

• Rock formed from the compression of sediments.

• Rock that forms from the alteration of existing rocks due to heat and pressure.

• Rock that forms from the evaporation of water in lakes and seas.

Metamorphic Rock

• Rock formed from cooling magma.

• Rock altered by pressure and heat.

• Rock made from compressed sediments.

• Rock that has undergone weathering.

Subsidence

• The rising of regions of the Earth's crust to higher elevations.

• The sinking of regions of the Earth's crust to lower elevations.

• The lateral movement of tectonic plates.

• The process of soil erosion due to water flow.

Rock Cycle

• The process of erosion and sedimentation.

• The series of processes that change one type of rock into another type of rock.

• The formation of igneous rocks from magma.

• The breakdown of rocks into smaller particles.

Composition

• The process of rock formation

• The chemical makeup of a rock; describes either the minerals or other materials in the rock.

• The age of a rock

• The texture and color of a rock
