Energy and Earthquakes etc.

Where does the energy come from that creates earthquakes and causes volcanoes to erupt?  Is this energy similar to the energy of a meteor impact?

Erosional Forces, Weathering, and Rock Cycle

How do erosional forces relate to the rock cycle and weathering? 

Erosional Forces At Home

We have been discussing three major erosional forces. Which force do you think had the most impact on Maine in the past? Which force do you think has the greatest impact currently? Finally which erosional force do you think will have the greatest impact on Maine's future?

Erosion on the beach

This is a sand fence on Nantucket Island Mass. What does this fence tell you about wind erosion and the dunes? Why do you think there is more sand on one side of the fence? Why do you think the fence was put there? Feel free to do some web research to help answer these questions. Also post any additional questions that this picture brings to you. 

Racing Rocks of Death Valley

You may have notice animal tracks in sand but, have you ever seen boulder tracks? If you ever go to the racetrack in Death Valley this is exactly what you will see. Rocks at the race track seem to move without any help. 

1. No one has ever seen a rock move at the race track. What evidence is there that these rocks are moving with or without human interference? 

2. Develop and post a theory that explains the mysterious movement at the racetrack. 

Erosional Forces

Name three erosional forces and explain if you think they cause small scale changes to the surface of the earth or large scale changes.
