  1. The Rock Cycle By: Baylee

  2. introduction • We have been studying the Earth and rock cycle in class. Most of what we have learned has come from our readings and class discussion, as well as a few activities. This web quest is designed to help you gain a deeper understanding of the rock cycle by using internet resources. You will be working on the tasks listed below independently.

  3. How Rocks are Formed • Short Video: http://www.watchknowlearn.org/Video.aspx?VideoID=44186&CategoryID=4761 • The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. • Igneous rock forms when magma cools and makes crystals. Magma is a hot liquid made of melted minerals. The minerals can form crystals when they cool. Igneous rock can form underground, where the magma cools slowly. Or, igneous rock can form above ground, where the magma cools quickly.

  4. Igneous • Igneous rocks are called fire rocks and are formed either underground or above ground. Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets. As these pockets of magma cool slowly underground, the magma becomes igneous rocks. • Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's surface. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground. Task: watch video http://www.youtube.com/watch?v=FnoHDRPJjkw&safe=active

  5. Sedimentary • For thousands, even millions of years, little pieces of our earth have been eroded--broken down and worn away • by wind and water. These little bits of our earth are washed downstream where they settle to the bottom of the rivers, lakes, and oceans. Layer after layer of eroded earth is deposited on top of each. These layers are pressed down more and more through time, until the bottom layers slowly turn into rock. • Task: make a poster about sedimentary rocks using publisher. http://www.fi.edu/fellows/fellow1/oct98/create/sediment.htm

  6. Metamorphic • Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks. How do sedimentary and igneous rocks change? The rocks are under tons and tons of pressure, which fosters heat build up, and this causes them to change. If you exam metamorphic rock samples closely, you'll discover how flattened some of the grains in the rock are. Task quiz: http://www.quia.com/quiz/1195085.html • Number correct here: ____
