Ride the Rock Cycle

Ride the Rock Cycle STUDENT WORKSHEET ANSWER KEY Site #1: Study Jams- Watch the video to complete this section. 1. Complete: Heat and pressure melts metamorphic rock and turns it into magma. When it cools it becomes igneous rock. 2. Igneous rock can be broken down by weathering and the pieces moved around by erosion. The mix of pieces become sedimentary rock, such as limestone. 3. The weight and pressure creates heat causing the sedimentary rock to turn into metamorphic rock, such as marble. 4. Try the quiz by clicking the Test Yourself button. How did you do? ?? out of 7 correct Site #2: Learner.org - Rock Cycle - Click "Begin with Types of Rocks" to start. 1. Identify each type of rock. IGNEOUS rocks are formed when magma cools and hardens. SEDIMENTARY rocks are formed from particles of sand, shells, pebbles, & other fragments. that are often compacted or cemented together. METAMORPHIC rocks are formed under the surface of the earth from the metamorphosis (change) that occurs due to intense heat and pressure (squeezing). Sample 2. Read the descriptions of each characteristic that can help you identify and classify rocks and then click "Next: Start Your Rock Collection". Follow the directions to collect samples. 3. Read the description of each rock to complete the first column in the chart with the key characteristic you might observe in each one. 4. Click the link to "Identify Rock Types" and complete the activity. Fill in the second row of the chart as you do the activity using I for igneous, S for sedimentary, and M for metamorphic. 5.

Click the link to move to the next chapter about "How Rocks Change" and read the information to complete each statement. Click "Next" to move through the chapter. A. The changing of rocks from one type to another is called the ROCK CYCLE. Rocks can be changed by HEAT and PRESSURE, such as an igneous rock being changed into a metamorphic rock. B. Rocks can be changed by MELTING and COOLING, which creates magma or lava that cools and crystallizes. C. Rocks can be broken down by WEATHERING and EROSION into smaller pieces called sediment, which can be COMPACTED together by pressure or CEMENTED together by minerals. 7.
