Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Weathering, erosion, deposition, compaction, and cementations creates which type of rock?
A
Igneous
B
Sedimentary
C
Metamorphic
D
None of the above
Explanation: 

Detailed explanation-1: -Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock.

Detailed explanation-2: -Clastic Sedimentary Rocks: Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped.

Detailed explanation-3: -Sedimentary rocks that form from sediments are called “clastic rocks. “ Clastic rocks are rock fragments that are compacted and cemented together (Figure below).

Detailed explanation-4: -Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth’s surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place.

Detailed explanation-5: -Igneous rocks can become sedimentary rocks by weathering, erosion, deposition, and compaction. Igneous rock at Earth’s surface breaks down into sediments by weathering. Erosion carries the sediments and deposits them in layers. Over time, these layers become buried and compacted to form sedimentary rock.
