How are structural plains formed?

Structural plains: These are the extensive lowlands of the earth bordering all the continents. These plains are mainly formed by the up liftment of a part of the sea-floor or continental shelf. The south eastern plains of the United States formed by the up liftment of a part of the Gulf of Mexico are an example of this type of plains. The structural plains may also be formed by the subsidence of areas. One such example is the central low-lands of Australia.

How were the soil of Gangetic plains formed?

The soil of the Gangetic plains was primarily formed from the deposition of sediment carried by the Ganges and its tributaries over thousands of years. The fertile alluvial soil is composed of silt, clay, sand, and organic matter, making it highly productive for agriculture. This process continues as the rivers continue to deposit sediment during the monsoon season.


How are glacial plains formed?

Glacial plains are formed by the deposition of sediments carried by glaciers as they advance and retreat. When glaciers move, they pick up rocks, soil, and other materials, which are then deposited when the glacier melts. Over time, these deposited materials accumulate to create flat, wide expanses of land known as glacial plains.
