What is the difference between surface mining and deep mining?
GeologySurface mining can be done on the surface, such as mountain top, beaches. Underground mining is done by digging tunnels to extract minerals that are too far underground to be reached from surface mining. In alluvial mining, minerals are extracted by dredging alluvial deposits. What is the difference between surface mining and mining? Surface mining

What do you mean by Moho discontinuity?
GeologyThe Moho is the boundary between the crust and the mantle in the earth. This is a depth where seismic waves change velocity and there is also a change in chemical composition. Also termed the Mohorovicic’ discontinuity after the Croatian seismologist Andrija Mohorovicic’ (1857-1936) who discovered it. Where is the Moho discontinuity? Moho, or Mohorovičić

How are volcanoes formed at convergent plate boundaries?
GeologyIf two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. … The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.Nov 29, 2021 What convergent plate

Why are volcanoes on plate boundaries?
GeologyAt constructive plate boundaries, the tectonic plates are moving away from one another. The Earth’s crust is pulled apart to create a new pathway for rising hot magma to flow on to the surface. Volcanoes can sometimes form in these setting; one example is Iceland. Do volcanoes always occur at plate boundaries? Volcanic eruptions occur
