  1. Constructive and Destructive Processes

  2. Constructive Process • Things that happen to the Earth that build it up or make positive changes.

  3. Destructive Process • Things that happen to the Earth that destroy or break down part of it.

  4. Erosion • A destructive process where materials are removed from the surface of the Earth and then deposited elsewhere.

  5. Weathering • A destructive process where rocks, soil, and minerals are broken down through contact with atmospheric conditions. (physical and chemical weathering) • Physical Chemical

  6. Deposition • A constructive process where sediments are added to land and build it up from previously eroded sediments

  7. Floodplains • Flat land beside a river or stream that stretches to a valley or mountain wall causing flooding during high periods of rain. Which Landform is a floodplain? 1 2 3 4

  8. Deltas • A landform that is formed at the mouth of a river where it flows into another body of water and sediments are deposited there. Which Landform is delta? 1 2 3 4

  9. Moraines • An accumulation of soil and rock that is formed by moving glaciers Which Landform is a moraine? 1 2 3 4

  10. Earthquakes • A constructive process that results in a sudden release of energy in the Earth’s crust where plates slip and move and displacement of land occurs. • Before: After: The earthquake that hit Japan in 2011 moved the coast line.

  11. Volcanoes • A constructive process where an opening in the Earth’s surface ruptures and allows magma, ash, and gases to escape.
