Sediments derived primarily from the products of weathering on the continents are called a. terrigenous sediment b. hydrogenous sediment c. biogenous sediment d. calcareous ooze

The correct answer is - a. terrigenous sediment.

The terrigenous sediments are sediments that are derived from the land masses, the continents. The name terrigenous itself suggests that, as terra means land/Earth.

The source of the terrigeous sediments are numerous, including the volcanoes, sediments carried by icebergs, glacial grinding, the weathering of the rocks, as well as the wind blow dust.

Most of these sediments end up dispersed and deposited on the continental land masses and on the coastlines, though parts of them also end up in the water bodies.
