An earthquake is caused by the magma/lava under the earth making the tectonic plates move by pushing together or the sides pushing and moving at the same time. We live on tectonic plates. Earthquakes change the surface on the earth by forming mountains and damage buildings and houses. The Richter Scale measures the level of the earthquake. The Richer Scale is from 1-9, with a one being very low and a nine being very high. It is important for people to learn more about earthquakes because we will be able to know how bad earthquakes can get. Also for us to tell if buildings are going to be badly damaged or not. Earthquakes last for about fifteen seconds.
Earthquakes are most likely to occur near the edge of tectonic plates. This is called a Fault Line. Fault lines are hidden under the ground, and are not visible to living things. Fault lines are usually found in the ocean and where the ocean meets the land.
Volcanoes change earth's surface by forming more land. They erupt and then after, the lava turns into rock. But if the lava hits the water around an island it turns into rock quicker than if it stays on land.

I got the idea for the Glossary and Richer Scale from Adisa's Dragon Den.

The nervous system is important because if we didn't have the nervous system we wouldn't be able to use our senses. It controls your eyes, your ears, your nose, your mouth, and your sense of touch. Your brain has a path which connects to your eye. Once one of your brain sells breaks your brain can not replace it. Your spinal cord connects to your brain. Your brain tells you what to do, both voluntary or involuntary. Your brain, your spinal cord and your nerves are the most important parts of your body. The brain receives information and messages from the outside of the body through your eyes, ears, mouth, nose and skin. For example: if someone touches you, you would feel it. You feel it because your skin has nerves in it. Your nervous system works with muscles by sending messages through your body with electricity to the muscles. The only involuntary muscles are your heart beating and your lungs breathing. "The brain sends signals to our organs to keep them working without us even thinking about it." -Discovery Education.We have lots of long stick-like things in the back of our eyes called cones. We have long ones and short ones. The short ones help you see color and the long ones help you see black and white. We have two sides of our brain. The left side of your brain surprisingly controls the right side of your body and the right side of your brain controls the left side of your body. It takes a lot of information moving through your nervous system to make your body move from one side of your body to the other side of your body. Our brain is very interesting.

I think our sample of dirt [chex-mix and skittles] is a Mixture because the objects are mixed together and can be taken apart. It is also a solid and mass. There is more healthy soil than contaminated soil. The soil is mostly healthy but it is also a little irritated.
