Question

multiple choice question
lithogenous sediments, those that are derived from preexisting rocks, are often also described as terrigenous, meaning that they are derived from ______

plant materials
seawater
space
land

Explanation:

The term "terrigenous" comes from the Latin "terra" meaning "land". Terrigenous sediments (a type of lithogenous sediments) are derived from land - based sources like weathered rocks on land, transported by agents like rivers to other areas (like oceans). Plant materials would relate more to biogenous sediments, seawater to hydrogenous sediments, and space to cosmogenous sediments. So the correct source for terrigenous (lithogenous) sediments is land.

Answer:

D. land
