Land Changes When two massive plates meet at a convergent boundary, the impact buckles one or both edges of the plates, shifting them upwards to create mountains and sometimes volcanoes – or it can bend one of the plates to create a deep marine trench on the seabed. In divergent boundaries...
Why do earthquakes happen at convergent plate boundaries? Convergent plate boundaries The plates move towards one another and this movement can cause earthquakes. ... This happens becausethe oceanic plate is denser (heavier) than the continental plate. When the plate sinks into the mantle it melts...

In the future, scientists will be able to predict eactly when and where earthquakes will take place. Then they will be able to tell people to take precautionary measures. Thus lives can he saved and damage can be lessened. 地震可能发生在地球表面的任何地方。在所有的地震中,振动使地球表面颤抖...
Scientists subsequently found that during a slow earthquake,the risk of regular earthquakes can increase, particularly in subduction zones. The locked part of the fault that produces earthquakes is basically being stressed both by regular plate motion and by the irregular periodic backward mo...
aGeodynamics is a subfield of geophysics dealing with dynamics of the Earth. It applies physics, chemistry and mathematics to the understanding of how mantle convection leads to plate tectonics and geologic phenomena such as seafloor spreading, mountain building, volcanoes, earthquakes, faulting and so...
To reiterate, we’re interested in the depth of earthquake focus specifically on destructive plate boundaries. Knowing the depth helps us estimate the potential severity of earthquakes. We need to find the average event depth within each UTM zone...
Tectonic earthquakes are a common cause of tsunamis. They often occur in areas where two crustal plates are pushing against each other, forcing one plate to slide under the other. These earthquakes shift the crust of the earth, leading to a rapid drop or rise of sea floor. When this happen...
Earthquakes may happen anywhere on the earth. The surface of the earth has many plate pieces (板块). These plates are always moving. When two plates move past each other, there is an earthquake. Many earthquakes begin under the sea. They often happen near the moun...
