Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How do earthquakes occur?
A
When a tsunami happens
B
When birds fly
C
When two plates rub against each other
D
when a volcano erupts
Explanation: 

Detailed explanation-1: -Some plates move away from each other, and the consequence of this is that they are pushed against another plate at the other end. This push increases the stress along that fault, readying it for an earthquake.

Detailed explanation-2: -If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common at subduction zones as well.

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 transform plate boundary occurs when two plates slide past each other, horizontally. A well-known transform plate boundary is the San Andreas Fault, which is responsible for many of California’s earthquakes.
