Essential Question:
Change is in everything. How does geology demonstrate the changes that Earth goes through in its history?

CALLING ALL MASTER GEOLOGISTS!
You are transported into the future of Planet Earth! There is a team of astronauts who are assigned a special mission to bring colonies onto planets so they can settle in other worlds. The team is searching for one geologist to take with them for every planet they settle. They need someone who is an expert on weathering and erosion because some of the planets that are targeted for settlement have elements that suggest dramatic weathering and erosion. There are steep cliffs, chemical rains, harsh weather, and many glaciers.
If you can accomplish this web quest, you will be one of the lucky ones chosen to go into space and help colonize other worlds.
Good Luck!
Change is everywhere around us. You can't stop change. The earth turns away from the sun every day. Seasons bring colder weather, then warmer. Puppies grow into adult dogs. Right now, you are growing too. Unlike you and your dog, sometimes things get smaller the older they get. When grapes rot on the vine then fall off to fertilize the soil, they get smaller as they get older. Changes in the landscape can either grow or become smaller. When a volcano under the sea makes an island by throwing lava out into the air, it falls down and piles up until it gets so tall, it begins to stick out of the water. This is an island.
Mountains can build this way or they can be broken down by the elements. Water is a powerful force that causes mountains and land forms to shrink away from weathering and erosion. Wind can have an effect also. Between wind and water, water is the strongest. What is the difference between weathering and erosion? This webquest will leave you with the answers.

Task 3
Weathering is simply erosion that doesn't move anywhere. Erosion is the movement of materials from their original place of rest. Look at these examples of erosion and weathering in this film as you follow the process through different events that happen to the land we live on.

Task 4
You will notice on the following web site, the land has been taken away; either downstream or onto another part of the land nowhere near where it started. This is called EROSION. When a rock, boulder or large land mass breaks off where it stands and the part that leaves, just stays where it fell, it is called WEATHERING. When the particles or larger parts are carried away from where they broke off, it is called EROSION.
