What is a volcanic eruption?

Back

A volcanic eruption is a rapid change in the Earth's surface caused by the release of magma, gases, and ash from a volcano, which can create new land and destroy existing ecosystems.

Front

How are sand dunes formed?

Back

Sand dunes are formed through wind erosion and deposition, where wind moves sand particles and deposits them in mounds.

Front

What causes a U-shaped valley to form?

Back

A U-shaped valley is formed by the massive weight of glaciers scraping and moving through the valley, eroding the landscape.

Front

What is a landslide?

Back

A landslide is a rapid change in the Earth's surface where land on the side of a mountain erodes and moves downwards, often destroying everything in its path.

Front

How are deltas formed?

Back

Deltas are formed by sediment deposition at the mouth of a river, where the river slows down and drops its sediment load.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass, often occurring in areas where the energy of the transporting medium decreases.

Front

What role do glaciers play in shaping the landscape?

Back

Glaciers shape the landscape by eroding land as they move, creating features like U-shaped valleys and fjords.

Front

What is sediment?

Back

Sediment is small particles of rock, soil, and organic material that are transported by wind, water, or ice.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks and minerals at the Earth's surface, while erosion is the movement of those materials from one location to another.
