Geological Processes and Features

erosion

• is the moving away of rocks and soil by wind, water, or glaciers.

• is the process of rocks being formed from molten lava.

• is the breaking down of rocks into smaller pieces by weathering.

• is the accumulation of sediments in a riverbed.

weathering

• is the breaking down of rocks into sediment. This can be physical or chemical.

• is the process of rocks being formed from magma.

• is the movement of rocks from one place to another.

• is the process of rocks being melted into lava.

delta

• is a type of fish found in rivers.

• is a landform created by the deposition of sediment at the mouth of a river.

• is a measurement of the distance between two points.

• is a type of cloud formation.

What natural  process changes the coast of Louisiana the fastest?

• Flooding

• Erosion

• Hurricanes

• Tsunamis

deposition

• is the process of breaking down rocks into smaller pieces.

• is the laying down of sediments carried by wind, water, or ice.

• is the movement of sediments from one location to another.

• is the process of water evaporating from the surface of the earth.

levee

• A structure built to hold back water from a river.

• A ridge built up by sediment that has been deposited alongside a river.

• A type of dam used to create reservoirs.

• A natural formation of rocks along a coastline.

chemical weathering

• is when the minerals in a rock are changed, causing the rock to break down.

• is the process of rocks being worn away by wind and water.

• is the formation of new minerals in rocks due to heat and pressure.

• is the movement of rocks from one place to another by natural forces.

An example of a slow land change to the Earth’s surface is 

• Volcanoes

• Earthquakes

• Mountains

• Floods

physical weathering

• is when bigger rocks are broken down into smaller pieces.

• is the process of rocks melting due to heat.

• is the formation of new minerals from existing rocks.

• is the movement of rocks from one place to another.

sediment

• is bits of broken rock that are carried by wind, water, or glaciers.

• is a type of soil that is rich in nutrients.

• is a form of liquid rock found in volcanoes.

• is a mineral that forms in the ocean.
