Identifying Fluvio-Glacial Deposits

Fluvio-glacial deposits are sediments laid down by meltwater streams flowing from glaciers or ice sheets. These deposits often form distinct landforms associated with glacial environments.

Analyzing the Options

• Pediplain: This is a landform created by extensive erosion, often forming a large, nearly flat area. It is not primarily a glacial deposit.
• Kame terrace: This is a ridge or flat area formed by meltwater streams flowing between a glacier and the valley side. It consists of sorted sand and gravel deposited by the meltwater, fitting the definition of a fluvio-glacial deposit.
• Floodplain: This is a flat area adjacent to a river, built up by sediments deposited during river floods. While it involves water deposition (fluvial), it is not necessarily linked to glacial meltwater.
• Loess plain: This landform consists of wind-deposited silt (loess). The depositional process is aeolian (wind), not fluvio-glacial.

Based on the definition, a kame terrace is the correct example of a fluvio-glacial deposit among the choices.
