Differentiate between Earthquakes and Volcanoes
Answers
Answer:
earthquakes:
Earthquakes are not a geological structure like volcanoes and they do not release magma. They are violent movements of the Earth's crust. However, unlike volcanoes, earthquakes are common to all types of plate boundary. Earthquakes occur as a result of friction and build up of pressure between plates./
Explanation:
volcanic eruption occurs due to excretion of magma / lava from the earth's crust
Volcanoes only occur at convergent and divergent plate boundaries. At convergent boundaries, one plate is forced below the other, forming a ridge along which mountains and volcanoes develop. Huge forces are exerted as the plates meet. This causes cracks to occur in the crust, which are filled by magma escaping from the mantle, ultimately producing a volcano, as described by BBC Bitesize. In contrast, the plates moving in opposite directions at divergent boundaries cause the crust to break apart, leaving a gap. This gap is filled by magma, forming new crust at the boundary, according to Classroom of the Future. Volcanoes are formed where this magma reaches the surface. When pressure within volcanoes builds up to a certain level, they erupt, spewing molten magma and debris over the surrounding areas.
The difference between volcano and earthquake:
•Volcano occurs at the planetary surface whereas earthquake occurs in the interior part of the earth crust.
•Volcano is always forms new rocks whereas earthquake releases seismic waves.
•Volcano can be predicted before eruption but earthquakes cannot be determined in a fixed time frame.
•Volcano is always produce the ash and debris whereas earthquake produces only debris due to the disturbance on the earth crust.
