What are volcanic debris avalanches?

What 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

What causes plate tectonics quizlet?

convection currents are a process in which the materials inside the mantle heat up and rise to the surface whilst the cooler liquid sinks; as it sinks it then heats up and rises again. This continuous cycle is established: hot liquid rising, cold liquid descending. These currents cause the tectonic plates to move. What causes

What is the definition of forensic Taphonomy?

Forensic taphonomy has been defined simply as the study of what happens to a human body after death (5, 6). What is a forensic archaeologist? The forensic archaeologist combines knowledge of osteology and human remains with archaeological techniques to help recover finds and provide vital evidence for the investigative team. What is the best definition

Why is the continental crust thicker than oceanic crust?

At 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 are the 7 properties of minerals?

Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity. What are the 7 properties of rocks? What are the 7 characteristics of rocks? Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage.

What is the definition of earthquake fault?

What 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
