Question

Select the statement(s) that accurately describe characteristics of sedimentary rock.


Sedimentary rock is caused by surface geological processes.

Sedimentary rock is often found near bodies of water or places that once were covered by water.

Sedimentary rock is the most common type of rock found on the Earth's surface.

Sedimentary rock is formed through heat and pressure.

Sedimentary rock is the most common type of rock found beneath the Earth's surface.

Answer 1

Correct choices: 1, 2, and 3.

- 1 (true): Sedimentary rocks form from surface geological processes (weathering, erosion, transport, deposition).
- 2 (true): They commonly form in or near bodies of water (rivers, lakes, oceans) or in places that were once underwater.
- 3 (true): Sedimentary rocks are the most common rock type covering the Earth's surface (they form a widespread surface veneer).

- 4 (false): Rocks formed by heat and pressure are metamorphic, not sedimentary.
- 5 (false): Beneath the surface, igneous and metamorphic rocks are more common; sedimentary rocks are mainly a relatively thin surface cover.
