Why is sedimentary rock found in basins?
A) The whole Earth is a basin.
B) Volcanoes eject sedimentary materials into basins.
C) Clastic sediment erodes from high-standing areas and is transported primarily by water to be deposited in low areas.
D) Plate boundaries grind together at basins to form sediment.

Question

Quizplus · Accepted Answer

Sedimentary rocks are formed through the accumulation of sediment, which is typically eroded from high-standing areas and transported to be deposited in lower-lying areas, such as basins. This sediment can be carried by water, wind, or ice and can accumulate over time, eventually forming layers of sedimentary rock. Volcanic eruptions may deposit some sedimentary materials into basins, but this is not the primary mechanism for their formation. Plate boundaries that grind together would typically produce metamorphic or igneous rocks, not sedimentary rocks. While the whole Earth could be considered a basin, the term typically refers to a depression or low-lying area where sediment can accumulate over time.
