A plateau is a flat, elevated area of land that rises sharply above the surrounding area.

Front

How do fossil fuels form?

Back

Fossil fuels form when dead organisms are buried beneath sediment and exposed to heat and pressure over millions of years.

Front

What is cementation in geology?

Back

Cementation is the process where layers of sediment become stuck together to form sedimentary rocks.

Front

What type of rock is formed from compressed sediments?

Back

Sedimentary rock is formed from layers of compressed sediments.

Front

What causes the formation of a valley?

Back

A valley can be formed by erosion, often caused by water or glaciers.

Front

A landform is a natural feature of the Earth's surface, such as mountains, valleys, plateaus, and plains.

Front

What is the difference between igneous and sedimentary rocks?

Back

Igneous rocks are formed from cooled magma or lava, while sedimentary rocks are formed from compressed sediments.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces by natural forces.
