Earth Changes

Front

What is a constructive process in Earth changes?

Back

A constructive process is a natural process that builds up landforms, such as the formation of mountains when tectonic plates push together.

Front

What is a destructive process in Earth changes?

Back

A destructive process is a natural process that breaks down landforms, such as erosion and weathering.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform, leading to the growth of features like deltas.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind or water.

Front

What is a delta?

Back

A delta is a landform created by the deposition of sediment at the mouth of a river, where it meets a body of water.

Front

What is a flood?

Back

A flood is an overflow of water onto land that is normally dry, often caused by heavy rainfall or melting snow.

Front

What is a Geographic Information System (GIS)?

Back

GIS is a technology that captures, stores, analyzes, and manages spatial or geographic data, often used for mapping and modeling.

Front

How do humans control flooding?

Back

Humans control flooding through structures like levees, dams, and floodwalls that help manage water flow.

Front

What is the role of volcanoes in land formation?

Back

Volcanoes contribute to land formation through the process of deposition when lava cools and hardens, creating new land.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces through natural forces like wind, water, and temperature changes.
