Question

1. match the steps with the descriptions of how sedimentary rock is formed.

______ layers of sedimentary rock form over time and under pressure.
______ eroded rock settles down in a process called deposition.
______ rocks on the earths surface get weathered.
______ weathered rocks are eroded by wind and water.

Explanation:

To solve this, we analyze the sequence of sedimentary rock formation:

1. Rocks on the earth's surface get weathered: This is the first step, as weathering breaks down rocks on the surface.
2. Weathered rocks are eroded by wind and water: After weathering, erosion transports the weathered material.
3. Eroded rock settles down in a process called deposition: Eroded material is deposited in a new location.
4. Layers of sedimentary rock form over time and under pressure: Over time, deposited layers are compacted and cemented into rock.

So the correct matching (from top to bottom, the steps correspond to the descriptions in the order 4, 3, 1, 2):

1. $\boldsymbol{4}$: Layers of sedimentary rock form over time and under pressure.
2. $\boldsymbol{3}$: Eroded rock settles down in a process called deposition.
3. $\boldsymbol{1}$: Rocks on the earth's surface get weathered.
4. $\boldsymbol{2}$: Weathered rocks are eroded by wind and water.

(Note: If the dropdowns are labeled with numbers or steps, the order of the steps in the formation process is: Weathering (step 1) → Erosion (step 2) → Deposition (step 3) → Compaction/Cementation (step 4) to form sedimentary rock.)
