For the next few weeks we will be spending time learning about ROCKS! One of my favorite subjects, studying rocks is one of the ways that we can understand and uncover the history of the Earth. This is a picture of one of my favorite rocks. Half-Dome, as it is called, is a massive rock in Yosemite National Park. The rock was formed deep under the surface of the Earth as the molten rock slowly cooled. After a long period of time the ground above the rock eroded away, leaving this beautiful rocky valley behind. At some point, a glacier moved through this valley and you can almost see the path it took as it sliced Half-Dome apart. Half-Dome is one of the greatest rock climbing destinations of the world.


Go to the following website:

Choose an igneous rock to read about. Click on the link to the rock of your choice.

Write 7-10 facts about the rock and post them (in your own words, complete sentences).
