Regional SpecificsThere are four types: lithogenous, hydrogenous, biogenous and cosmogenous. What are the 4 different types of marine sediments and their sources? There are four types of sediment: cosmogenous (from outer space), volcanogenous (ash from volcanic eruptions), terrigenous (continents erosion and river runoff), and biogenous (skeletons of marine creatures). Sediments are classified according to their size.

What do Stratovolcanoes look like?
Regional SpecificsStratovolcano. Stratovolcanoes have relatively steep sides and are more cone-shaped than shield volcanoes. They are formed from viscous, sticky lava that does not flow easily. The lava therefore builds up around the vent forming a volcano with steep sides. What does an eruption from a stratovolcano look like? Stratovolcanoes are composed of volcanic rock types

For this reason, the thickest parts of continental crust are at the world’s tallest mountain ranges. Why oceanic crust is thinner compared to continental? The oceanic crust is thin, relatively young and
