Types of Plateaux - SS1 Geography Lesson Note

Dissected Plateau:

These plateaus have been eroded over time by rivers and weathering, resulting in a series of deep valleys and ridges.

The Deccan Plateau in India is an example of a dissected plateau.

 

Volcanic Plateau:

Formed by the accumulation of volcanic lava and ash over time, creating a flat or gently sloping surface.

The Columbia Plateau in the United States is a notable volcanic plateau.

 

Tectonic Plateau:

These plateaus are uplifted due to tectonic forces, like the collision of tectonic plates or the upwelling of the Earth's mantle.

The Tibetan Plateau, also known as the "Roof of the World," is a famous tectonic plateau.

 

Lava Plateau:

Formed from repeated volcanic eruptions that cover a large area with basaltic lava flows.

The Snake River Plain in the United States is an example of a lava plateau.

 

Piedmont Plateau:

These plateaus are situated at the base of a mountain range and have a relatively flat or gently rolling surface.

The Appalachian Plateau in the eastern United States is a piedmont plateau.

 

Intercrater Plateau:

Found on the Moon and other celestial bodies, they are flat areas between impact craters.

The lunar highlands contain intercrater plateaus.

Each type of plateau is shaped by different geological processes, and they can vary in size, elevation, and geographical location. Plateaus have significant ecological and geological importance, and they are often home to unique ecosystems due to their relatively stable and flat terrain.
