Volcano is a place on the earth’s surface (or any other planet) where molten rock and gases are erupted. or hill or mountain built up by the eruption of molten rock.Volcanic eruptions are caused by magma (a mixture of liquid rock, crystals, and dissolved gas) expelled onto the Earth’s surface. Basaltic magmas tend … Read more
Interior of the earth- composition and physical conditions Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earth’s … Read more
Earthquakes and INFRASTRUCTURE, and it can also cause landslides and liquefaction. Tsunamis, which are large waves caused by earthquakes, can also cause widespread damage. Volcanoes are formed when magma, or molten rock, rises to the surface of the Earth. Magma can rise to the surface through cracks in the Earth’s crust, or it can erupt … Read more
Most of the knowledge we have about Earth’s deep interior comes from the fact that seismic waves penetrate the Earth and are recorded on the other side. Earthquake ray paths and arrival times are more complex than illustrated in the animations, because velocity in the Earth does not simply increase with depth. Velocities generally … Read more
Endogenic Processes Endogenic processes are processes that occur within the Earth’s crust. They are responsible for the formation of mountains, VolcanoesVolcanoes, and earthquakes. The following are some of the subtopics of endogenic processes: Convection currents Subduction Orogeny Volcanism: Earthquakes Plate tectonics: The theory that the Earth’s surface is made up of a number of plates … Read more
