Landforms and bodies of water

  1. 1. Landforms and Bodies of Water Pages 17 – 18
  2. 2. What is Topography?• The physical feature of a place or a region.• Can be natural or man – made.
  3. 3. What causes Topography? • Volcanic eruption • Soil erosions – Water – Wind
  4. 4. What causes Topography?WATER – The sun heats water, and itevaporates into the atmosphere. This waterthen falls back to the ground in the form ofrain. When it rains at any elevation abovesea level, the water then flows from highelevation down to sea level. The water thengroups together and forms rivers (or anybody of water) which cut the ground andwash loose dirt down.
  5. 5. What causes Topography?WIND – In areas where there is no water (thedesert) the wind is the primary erosionfactor. The wind picks up small particles ofsand and hurls it through the air and smacksit into rock, which breaks off small particles.
  6. 6. Landforms• Natural shapes or features of the earth.• There are many different types of landforms found on the earth.
  7. 7. Landforms1.Mountain 5. Plain 6. Valley2.Hills 7. Canyon3.Island 8. Plateau4.Desert
  8. 8. MOUNTAIN• A mountain is a place on Earth’s surface that is much higher than the land around it.• A mountain is the highest kind of land.• Taller than a hill.
