Science Benchmark
The Earths surface is
constantly changing. Some changes happen very
slowly over long periods of time, such as
weathering, erosion, and uplift. Other changes
happen abruptly, such as landslides, volcanic
eruptions, and earthquakes. All around us, we see
the visible effects of the building up and
breaking down of the Earths surface.

• Standard II
• Students will understand that volcanoes,
  earthquakes, uplift,
• weathering, and erosion reshape Earths surface.
  
• Obj. 1 Describe how weathering and
  erosion change Earths surface.
• Obj. 2 Explain how volcanoes, earthquakes,
  and uplift affect Earths surface.
• Obj. 3 Relate the building up and breaking
  down of Earths surface over time
• to the various physical land
  features.

  mountains cinder cone, shield volcano, composite
  volcano.

Objective 2 Explain how volcanoes, earthquakes,
and uplift affect Earths surface.

• Volcanic eruptions can create mountains and other
  landforms.
• Earthquakes can create small to large landforms,
  including mountains and valleys.
• Uplift can result in mountains and plateaus.
