Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, characterized by the deposition of sediment carried by the river as the flow velocity decreases.

Front

What process occurs when water freezes in the cracks of rocks?

Back

The process is called freeze-thaw weathering, where water expands when it freezes, causing the rock to break apart over time into smaller sediments.

Front

What natural event is most likely to cause sudden changes to the Earth's surface?

Back

An earthquake is a natural event that causes sudden shaking and changes to the Earth's surface due to the movement of tectonic plates.

Front

What is a volcano?

Back

A volcano is a hole in Earth's surface through which melted rock (magma), gases, and ash erupt, often forming a mountain or hill.

Front

What is an earthquake?

Back

An earthquake is a rapid shaking of the Earth's surface caused by the movement and grinding of tectonic plates.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries, causing geological activity such as earthquakes and volcanic eruptions.

Front

How do earthquakes affect the Earth's surface?

Back

Earthquakes can cause ground shaking, surface rupture, landslides, and tsunamis, leading to significant changes in the landscape.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through physical, chemical, or biological means.

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, water, or ice.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living organisms, often transported by water, wind, or ice.
