What is the correct order for the following statements to explain how sedimentary rocks are formed? [A] As these layers increase, the pressure on the bottom layers increases. [B] The small pieces of rock are transported, typically by water in rivers or seas. [C] The increased pressure removes water from the layers and cements them together, forming sedimentary rock. [D] Igneous, sedimentary, and metamorphic rocks are fragmented and disintegrated. [E] More and more rock, sand, and mud is deposited on top of each other, forming layers.

What is the correct order for the following statements to explain how sedimentary rocks are formed? (A) As these layers increase, the pressure on the bottom layers increases. (B) The small pieces of rock are transported, typically by water in rivers or seas. (C) The increased pressure removes water from the layers and cements them together, forming sedimentary rock. (D) Igneous, sedimentary, and metamorphic rocks are fragmented and disintegrated. (E) More and more rock, sand, and mud is deposited on top of each other, forming layers. (F) The small pieces of rock are then deposited.

Sedimentary rocks are rocks formed when existing rocks go through a series of processes. Each of the statements given, describes one of the steps necessary for forming sedimentary rocks. We need to put these statements in the correct order. We can use this diagram to help us understand how sedimentary rocks are formed.

First, rocks on the surface are weathered and eroded. During weathering, existing igneous, sedimentary, and metamorphic rocks are fragmented and disintegrated into smaller particles of rock or sediment. This first step corresponds to statement (D).

Next, the bits of rock and sediment are transported by air or water in rivers and seas. The second step corresponds with statement (B).

The next step is deposition. This is where the sediment is deposited into a layer. This step corresponds with statement (F).

The processes of weathering, transportation, and deposition repeat, creating more and more layers of sediment. This step corresponds with statement (E).

As the layers increase, the pressure on the bottom layers increases and the sediment is compacted. This step corresponds with statement (A).

The increased pressure also removes water from the layers, cementing the layers together. This produces sedimentary rock. This final step corresponds with statement (C).

So, the correct order of the statements to explain how sedimentary rocks are formed is (D), (B), (F), (E), (A), (C).
