Earthquakes !!!!

Hey, This is Anushka here.



I wanted to talk a little bit about earthquakes. So, what is an earthquake? How does it happen? Well, I will answer all these questions and many more.



So what is a earthquake?

A earthquake is a movement of the ground caused by a sudden release of energy in the earth's crust.






What causes an  earthquake?

An earthquake is caused if plates rub beside each other, if plates move away from each other, or if plates collide into each other.




                                        




Now, what exactly is a focus and an epicenter?

The place within the crust where energy is released during an earthquake is called a focus and the point on the earth's surface directly above the focus is called epicenter.

















What is a fault?

Most earthquakes occur along a fault, or break in the earth's crust.







What is a Richter Scale?

Scientists classify earthquakes by estimating their magnitude,or amount of energy released.






That's all for today folks.  Keep reading my blog!!! and.............
