Answer:
Wor Alluvium means to wash against, is a loose unconsolidated soil reshaped by water in soemfrom and redeposited in an non marine setting.
Explanation:
- Being typically made up of a variety of minerals like silt and clay. And larger particles of sand and gravel. When this loose material s being deposited and being cemented and lithified, its ten called as alluvial deposits.
- An alluvial fan is also the deposit left by the river like in lake sediments glacier sdimantand and river sediments. Belonging from the quaternary ages these are often referred to as "covers" as the sediments obscure the underlying sedimentary rocks.
- Alluvium contains ores of gold and platinum and a wide variety of gemstones. Such as the concentration of valuable ores and placer deposits. The marine sandstone, shale, and semi consolidated material occupy the major parts of the uplands.
Wind, density difference in water masses which is caused by temp and salinity variations, gravity and an event like an earthquake.
Answer:
Options (A), (D) and (E)
Explanation:
Mass wasting refers to the downward motion of sediments and rock particles along the slope of the area under the influence of gravity.
There are different types of mass wasting processes such as mudflow, slump, rockfall, debris flow and many more. This classification of mass wasting types are based on the 3 criteria namely-
- the type of motion of the materials
- the type of materials present in the flow
- the rate of movement of these sediments and materials.
For example, in the case of rockfall, the materials present in it are large fragments of rocks, the motion is vertical or nearly vertical and the particles fall at a rate of 10s of m/sec.
Thus, the correct answers are options (A), (D) and (E).
