Introduction
SHAKING! EVERYTHING IS SHAKING!
You are in class when all of a sudden posters start falling off the walls. The floor is shaking and your classmates are screaming. Teachers are running around and parents begin to show up.
------------------------------------------------
As you arrive home, you notice your father stressed and tired. He announces he has to go back to work. Your father is a Seismologists. You are unsure what your father does for a living, but you now know he is trying to help out with the chaos from earlier.
You become curious and you decide to do your research on what caused the shaking. You want to be able to help your father as much as possible. Your research now begins...
------------------------------------------------
The “shaking” described in this activity is a result of an earthquake happening. In this activity, you will learn… What is an earthquake? What causes an earthquakes? And much more.
Task
What are your tasks for this WebQuest?
By using https://www.ducksters.com/science/earthquakes.php you will be able to do the following:
1. Learn what Earthquakes, Foreshocks, and Aftershocks are
2. Discover the Different Parts of an Earthquake
3. Be able to measure an Earthquake
Imagine standing in a room while everything on the walls comes crashing down to the ground and the ground beneath is shaking violently while outside the window you see a giant ocean wave. Would you not be curious why this is happening?
Why can something out of our control cause so much damage?
Process
How do earthquakes happen?
The ground is made of different and independent types of rocks which are called tectonic plates.
There are fault lines or cracks on the surface of the earth which cause movements on the earth surfaces. The movements are so violent that depending on the intensity sometimes it will reshape the earth surface.
When the two fault lines start pulling away from each other due to the underground movement create an uneven ground which is not a peaceful process.

The 1906 San Francisco earthquake measured a magnitude 7.9 and ruptured 300 miles of the San Andreas Fault, which slipped as much as 20 feet in some places.More than 3,000 people died in the earthquake and the caused fire, making it the deadliest earthquake in U.S. history.
