Sediments derived primarily from the products of weathering on continents are called terrigenous sediments.

Here's why:

* Terrigenous comes from the Latin word "terra," meaning "earth."

* Sediments are loose, unconsolidated particles that are transported and deposited by various natural processes.

So, terrigenous sediments are essentially sediments that originated from the land, specifically through the weathering of rocks and other materials on continents.
