Dear Mr. President:

The research team has been studying earthquakes these past few weeks and have been plotting earthquakes that happen all over the world on a map. Doing this we have discovered a few interesting things.

First of all, as you know, the sudden movement of the crust causes earthquakes. Faulting is the most common reason for earthquakes. During faulting Earths crust breaks and earthquake waves travel through Earth in all directions. The lithosphere is relatively cool rock in a solid state and bellow it is hot rock. It is so hot that it is in a liquid state. That molten rock moves slowly. When two plates meet at a fault they either move away from each other, towards each other, or past each other. When the current in the molten rock pushes the plates hard enough to break, they shift suddenly, and an earthquake is caused.

When plotting the most recent earthquakes, weave noticed certain trends. There are certain parts of the world that tend to experience earthquakes more than others. They occur most often in the Ring of Fire. Also in New Zealand, the Mediterranean, Eurasia, and the west coast of America. We have also noticed that the earthquakes have an average magnitude of 4.0 to 6.0 on the Richter scale. The stronger ones occurring of course, if not in, near the Ring of Fire. The earthquakes aren't really deep. Most of them are only 10km or 33km deep. Some do get close to 400km deep, but only very few, which again, are close to the Ring of Fire.

Having all this in mind I think you should continue funding our research team because then we could learn more about earthquakes and where they are happening the most. Also, because in this way we could see what some of the effects are on Earth’s crust. Because earthquakes cause destruction I think it is important to know about them, and also to be aware where earthquakes are happening. In this way will know what places need more precautions and help.

Earthquakes can do a lot of damage so I hope you consider continuing funding the research team.

Sincerely,

Brenda
