How does plate tectonics cause volcanism and earthquakes?
Plates sliding past each other cause friction and heat. Subducting plates melt into the mantle, and diverging plates create new crust material. Subducting plates, where one tectonic plate is being driven under another, are associated with volcanoes and earthquakes.
What does tectonic plate movement cause?
Tectonic plates move around and can cause earthquakes and volcanic eruptions. First of all, it is important to know that the Earth’s crust is broken up into large pieces called tectonic plates. Remember, tectonic plates are giant pieces of the Earth’s crust that fit together and move around on the Earth’s surface.
Which type of plate movement is most often the cause of earthquakes?
About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on.
What will happen if tectonic plates continue to move?
Plate tectonics also has an impact on longer-term climate patterns and these will change over time. It also changes ocean current patterns, heat distribution over the planet, and the evolution and speciation of animals.
How do you know an earthquake is coming?
Watch for reports of “earthquake lights.” Days, or mere seconds, before an earthquake, people have observed strange lights from the ground or hovering in the air. Though they are not fully understood, earthquake lights may be emitted from rocks that are under extreme stress.
How long will the tectonic plates continue to move?
Every so often they come together and combine into a supercontinent, which remains for a few hundred million years before breaking up. The plates then disperse or scatter and move away from each other, until they eventually – after another 400-600 million years – come back together again.
