What are the four types of marine sediments?
GeologyThere 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?
GeologyStratovolcano. 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

What are volcanic debris avalanches?
GeologyWhat is debris avalanche? A debris avalanche is the sudden catastrophic collapse (landslide) from an unstable side of a volcano. Many volcanic cones are steep sided and unstable due to rapid growth of the cone. What is volcano debris? BGS Research — Volcanoes. Debris flows, also known as lahars when they involve volcanic material, are

Why is the continental crust thicker than oceanic crust?
GeologyAt convergent plate boundaries, where tectonic plates crash into each other, continental crust is thrust up in the process of orogeny, or mountain-building. 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

What is the definition of earthquake fault?
GeologyWhat is fault in earthquake? A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake – or may occur slowly, in the form of creep. What is an earthquake simple

Do stones move?
GeologyLocated on the border of California and Nevada, Death Valley National Park was designated in 1933, and is home to one of the world’s strangest phenomena: rocks that move along the desert ground with no gravitational cause. Known as “sailing stones,” the rocks vary in size from a few ounces to hundreds of pounds. Why
