While we will not be studying minerals specifically, they
are the building blocks of rocks. Rocks are made up of 1 or more
minerals. The different minerals determine the shape, color, and
other important features of a rock. Changing the minerals changes
the rock. To learn more about minerals click on the mineral to the
left to go to the Mineral Galleries website. You can also
check out mindat.org for more
information. |

Before we look at the Grand Canyon we need to study
the 3 basic types of rocks. Click on the picture of the rocks to
left if you need clarification on how the 3 types of rocks are formed. |

Rocks are constantly changing from one type to
another. This constant change is called the ROCK CYCLE. Click on the
illustration to the left to go to the NASA Classroom of the Future website
to get more information on how the rock cycle works. |

As we discussed in class, the earth is constantly moving
because we live on the crust which is made up of plates which
move. Click on the map of the plate boundaries to go to the Science
Odyssey website to read about what happens at each of the 4 types of plate
boundaries (divergent, convergent, collision, and transform). Don't
forget to click on the plate tectonics activity to see model plates
moving. |

Earthquakes are a result of plates moving and coming into
contact with one another. Click on the map to the left to go the
United States Geological Survey's website to see where earthquakes are
currently occurring. |
