State whether true or false.
1. Mountains are formed within a short period of time.
2. Mountains are a habitat for wildlife.
3. Rift valleys have a U-shaped structure.
4. The Great Plains of the USA is a type of erosional plain.
5. About 80% of the world's population lives on plateaus.
Answer (2)
Mountains take millions of years to form and provide wildlife habitats. Rift valleys have a V-shaped structure, while the Great Plains are a depositional plain. Most of the world’s population does not live on plateaus, but rather in lowland areas.

Let's evaluate each statement individually to determine if they are true or false.
Mountains are formed within a short period of time. False — Mountains are formed through geological processes such as tectonic plate movements, which occur very slowly over millions of years. These processes include the collision of land masses and volcanic activity, both of which take a very long time.
Mountains are a habitat for wildlife. True — Mountains support a variety of ecosystems and are home to diverse species of plants and animals. These habitats vary with elevation and climate, supporting unique wildlife adapted to their environments.
Rift valleys have a U-shaped structure. False — Rift valleys are typically V-shaped or have steep sides. They are formed by the movement of tectonic plates pulling apart, leading to a central depression or valley.
The Great Plains of the USA is a type of erosional plain. False — The Great Plains are primarily classified as depositional plains. They have been shaped by sediment deposits from rivers and wind, rather than being formed primarily through erosion.
About 80% of the world's population lives on plateaus. False — While plateaus can be densely populated areas due to their flat lands suitable for agriculture and settlement, the claim that 80% of the world's population lives on plateaus is exaggerated. Most of the world's population lives in coastal and lowland regions where resources and trade are more accessible.
