|
|
When a volcano erupts, releasing magma into the air, causing the convection currents in the mantle to move the tectonic plates, forming seismic waves that shake the Earth.
|
|
|
Sudden movement of land and rock underground, which leads to rubbing and collapsing on one another. This builds a lot of pressure, thus creating impacts and seismic waves that shake the Earth
|
|
|
When two tectonic plates move towards each other at very fast speeds, and the impact of the two plates colliding creates seismic waves that shake the Earth.
|
|
|
When two tectonic plates lock in place and rub against each other which builds up pressure. When the rocks break, or the tectonic plates slip past each other, the sudden release of these two plates releases all the pressure, energy and friction forming seismic waves that shake the Earth.

Detailed explanation-1: -The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel.
Detailed explanation-2: -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.
Detailed explanation-3: -Earthquakes occur along fault lines, cracks in Earth’s crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose.
Detailed explanation-4: -A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.
