  1. Energy In The Rock Cycle

  2. Energy In The Rock Cycle • The rock cycle shows the possible ways in which one type of rock can slowly change to another type of rock. • The rock cycle is driven by different types of energy that slowly change rock. • The changes in the rock cycle usually take thousands to millions of years.

  3. Solar Energy • Solar Energy drives the weather. • Weather erodes rocks. • Examples: • Wind breaks down rocks and moves sediments. • Rain slowly dissolves rock and moves sediments. • Ice Wedging - Snow melts and runs into cracks, freezes, expands, and breaks rock. • Glaciers scrape rock and carry sediment as they move. • Natural Disasters • Heat from the sun causes rock to crack or buckle from pressure caused by its atoms’ increasing speed.

  4. Gravity • All objects have gravity. • Earth’s Gravity pulls all objects towards the center of the Earth. • Gravity helps move rocks and sediment from place to place. • Examples: waterfalls, rockslides, mudslides, glaciers

  5. Chemical Energy • Chemicals dissolved in water harden sediments and cement them together to form new rocks as water evaporates or moves away. • Chemical reactions within the earth’s crust change rocks from one form to another.

  6. Heat • Earth was once a molten ball of rock. • The earth’s interior still contains molten rock and metal. • Heat in the earth’s interior causes convection currents in the mantle that move the earth’s tectonic plates, causing earthquakes, mountain building, and volcanic activity. • Heat inside the earth causes rocks to melt partially or completely.

  7. Radioactive Decay • Earth’s crust and mantle contain radioactive elements that heat rocks as they decay.

  8. Pressure • As sediments pile up they put pressure on lower sediments and smash them together to make rocks. • When the earth’s tectonic plates move they push against each other. The resulting pressure changes the crystal structure and composition of rocks.
