  1. How is Earth’s Surface Shaped and Reshaped By : Carina Sanchez

  2. Chemical Weathering • During chemical weathering ,chemicals cause rocks to change into different materials and break down • Water and warm temperatures are important for chemical weathering • Acid rain weathers rock material on rock’s surface Ravine Cleopatra’s needle was weathered by acid rain.

  3. Physical Weathering • In physical weathering , rocks are broken down into smaller pieces • Plants can also crack rocks • Glaciers are also an example of physical weathering Plants breaking through earth’s surface Glacier

  4. Erosion • Erosion is the movement of weathered materials Land slide

  5. Volcanoes • A volcano = a cone shaped land that forms at a weak spot In Earth’s crust where magma reaches the surface • Sometimes the pressure builds so much gas it explodes Volcanic eruption

  6. Earthquakes • Earth’s outer layer, or crust, is on top of another layer called the upper mantel • Fault=a break or crack where earth’s crust can move • Earthquake is the sudden movement that causes earth’s crust to shake A fault in the earth’s surface
