Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of rock is formed from smaller pieces of rocks that have been broken down?
A
Sedimentary rock
B
Metamorphic rock
C
Igneous rock
D
None of the above
Explanation: 

Detailed explanation-1: -Inorganic detrital rocks, on the other hand, are formed from broken up pieces of other rocks, not from living things. These rocks are often called clastic sedimentary rocks. One of the best-known clastic sedimentary rocks is sandstone.

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. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.

Detailed explanation-3: -Sedimentary rocks are formed from pieces of other existing rock or organic material. There are three different types of sedimentary rocks: clastic, organic (biological), and chemical. Clastic sedimentary rocks, like sandstone, form from clasts, or pieces of other rock.

Detailed explanation-4: -Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

Detailed explanation-5: -Weathering is the process of breaking down rocks and minerals into smaller pieces by water, wind, and ice. Sedimentary rocks are formed from the breaking apart of other rocks (igneous, metamorphic, or sedimentary rocks) and the cementation, compaction and recrystallization of these broken pieces of rock.
