GEOLOGY

Detailed explanation-1: -Lithogenous sediments are also commonly called “terrigenous sediments” because they are derived dominantly from terrigenous (land) sources. They are also called “clastic sediments” because they are made up of rock fragments derived from other rocks-a “clast” is a Greek word for a rock fragment.

Detailed explanation-2: -Alternate titles: clastic sediment, detrital sediment, land-derived sediment.

Detailed explanation-3: -These sediments are often referred to as terrigenous sediments, terra meaning earth. Lithigenous sediments are the most abundant type of sediment on Earth. Examples of lithogenous sediment include volcanogenic sediments, glacial marine sediments, and abyssal clays.

Detailed explanation-4: -Sand and gravel on SoCal beaches are typical lithogenous sediments. This view is of South Carlsbad State Beach, California. Lithogenous sediments are: Mostly small pieces of broken rock transported to ocean from the land (wind, rivers, glaciers, coastal erosion, turbidity currents etc.)
