  1. LandForms and Earth’s Processes Mission 1 By Tiffany West

  2. Let’s go on an adventure of discovery!

  3. Your Task: • Destructive Processes = Destroy • Constructive Processes = Build Up To investigate Earth’s landforms and discover how they are made! You must proceed with caution! All around you things will be destroyed and built up! Rocks change shape, size and/or form due to water or ice movement, freeze and thaw, wind, plant growth, gases in the air, pollution and catastrophic events such as earthquakes, mass wasting, flooding and volcanic activity

  4. Process 1:Weathering Watch how weathering and erosion work together to wear away rock! http://studyjams.scholastic.com/studyjams/jams/science/rocks-minerals-landforms/weathering-and-erosion.htm http://www.youtube.com/watch?v=_XnCTcjNpuc Weathering is a group of processes that break down rocks and sediment into smaller particles. Some weathering processes take a long time to occur, while some weathering processes occur quickly. Weathering can be caused by water, wind, ice, or plant roots. It is a “destructive” process.

  5. Process 2: Erosion Take a look at he link below to watch erosion in action! http://www.youtube.com/watch?v=ChEHQUMEkXw http://www.youtube.com/watch?v=Vy7nQdYx1qk http://www.youtube.com/watch?v=1E2Gu8Bh_To Erosion is a process that transports rock, soil or sediment to a different location. Water, wind and ice physically remove and carry (erosion) rock, soil and sediment and deposit the material in a new location. Erosion is a “destructive process”

  6. Process 3: Deposition Watch as the sediment is deposited. http://www.youtube.com/watch?v=8kgh1Zd32-Y www.youtube.com/watch?v=V9iqas7igcY Deposition happens when erosion deposits the material in a new location. The material builds up to make new landforms. Deposition is a “constructive” process

  7. Process 4: Flooding • Watch how scientists monitor streams and rivers to determine when a flood will occur. • http://www.youtube.com/watch?v=q4mdgrRxHyk Flooding is when water rises and overflows onto dry land. Water saturates the ground and washes away eroded rocks, soil and sediment. The water expands to cover more land and recedes back to its normal banks. Flooding is a “constructive” and “destructive” process What does flooding do to the rocks, soil, and sediment? How does flooding construct and destruct the land around it?

  8. Process 5:Glacial Movement Watch the incredible glaciers as they move massive amounts of rocks and sediment! http://www.youtube.com/watch?v=AG3luuhc-5Y http://www.youtube.com/watch?v=njTjfJcAsBg http://www.youtube.com/watch?v=NqcjF5C03DI The very slow movement of glaciers Glaciers are a large body of ice moving slowly down a slope or valley or spreading outward on a land surface Glaciers erode the land and deposit the land in new places. Glaciers are a “destructive” and “constructive” processes. What would the movement of a glacier do to a mountain? LOOK at the pictures!

  9. Process 6:Earthquakes • Read about earthquakes and learn about their causes! • http://earthquake.usgs.gov/learn/kids/eqscience.php • http://www.youtube.com/watch?v=I3hJK1BoRak A shaking or trembling of the earth that is caused by volcanic or tectonic activity As plates in the earth move past each other and cause friction, they create a vibration that makes the earth shake and move. Earthquakes are a “destructive” process What causes an earthquake?

  10. Process 7:Volcanic Activity Watch the destructive and constructive force of volcanoes! http://www.youtube.com/watch?v=h8W_sGYAQlc http://www.youtube.com/watch?v=WwBVG0Si7rs www.youtube.com/watch?v=xP2dreOI8gIp://www.youtube.com/watch?v=xP2dreOI8gI http://www.youtube.com/watch?v=xP2dreOI8gI Molten or hot rock and steam coming out of a vent in the crust of the earth A hill or mountain made up of material that comes out of a whole or crack in the earth Something of explosively violent potential Volcanic activity is a “destructive” and “constructive” process. - Watch the videos and explain: How is it destructive? How is it constructive?

  11. These processes constantly build up and tear down our Earth!

  12. Creating Landforms • Proceed to the 2nd power point.
