Question

Assertion (A): Many lakes exist in the vast lowland of the Great Plains of the USA.

Reason (R): The Great Plains were formed due to uplift of land submerged under water.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R does not explain A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is true but R is false.

Explanation:

• Assertion (A) is true because many lakes are found in the Great Plains of the USA. These lakes are often formed by glacial activity, river deposits, or geological processes.
• Reason (R) is false because the Great Plains were not formed by the uplift of land submerged under water. Instead, they were shaped primarily by erosion, sedimentation, and glacial actions. Therefore, R does not explain A.
