SEDIMENTS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Sediments are formed with the help of erosion and weathering
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The particle that helps in forming the sedimentary rock is called sediment. This sediment is formed with the help of erosion and weathering from the source area and is then transported to the deposition place by the wind, water, ice and glaciers, which are agents of denudation.

Detailed explanation-2: -Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones. Erosion and weathering transform boulders and even mountains into sediments, such as sand or mud. Dissolution is a form of weathering-chemical weathering.

Detailed explanation-3: -Erosion is the transport by wind, water and ice of soil, sediment and rock fragments produced by the weathering of geological features. Sedimentation occurs when eroded material that is being transported by water, settles out of the water column onto the surface, as the water flow slows.

Detailed explanation-4: -Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. Clastic sedimentary rocks may have particles ranging in size from microscopic clay to huge boulders.

Detailed explanation-5: -Soil is made when weathering breaks down bedrock and turns it into sediment. If erosion does not remove the sediment significantly, organisms can access the mineral content of the sediments. These organisms turn minerals, water, and atmospheric gases into organic substances that contribute to the soil.
