Question

Accepted Answer

The Lacustrine and Fluvial depositions in Kashmir Valley are called Karewa because:

*   **Karewa Formation:** The Karewa deposits are specifically known for being lacustrine (lake-related) and fluvial (river-related) sediments found in the Kashmir Valley. These deposits are terraced, flat-topped mounds composed of glacial till, clay, sand, and loess. The term "Karewa" itself refers to these elevated tablelands. The formation represents the sediments deposited in a large lake that once occupied the Kashmir Valley, which was subsequently drained and dissected by rivers. The alternating layers of clay and sand clearly indicate the lacustrine and fluvial origin.

Why the other options are incorrect:

*   **Khadar:** Khadar refers to the newer alluvial deposits found in floodplains of rivers, typically in the Indo-Gangetic plains. These are not specifically associated with the lacustrine and fluvial deposits of the Kashmir Valley.

*   **Chhos:** Chhos are seasonal streams or rivulets, often found in the Himalayan region. While they might contribute to fluvial processes, they are not the name given to the overall lacustrine and fluvial deposits of the Kashmir Valley.

*   **Murg:** The term "Murg" doesn't have a direct geological or geographical meaning related to lacustrine or fluvial deposits in the context of the Kashmir Valley or Indian subcontinent.
