What is Topography?
• The physical feature of a place

3.
What causes Topography?
• Volcanic eruption
• Soil erosions
– Water
– Wind

4.
What causes Topography?
WATER – The sun heats water, and it
evaporates into the atmosphere. This water
then falls back to the ground in the form of
rain. When it rains at any elevation above
sea level, the water then flows from high
elevation down to sea level. The water then
groups together and forms rivers (or any
body of water) which cut the ground and
wash loose dirt down.

5.
What causes Topography?
WIND – In areas where there is no water (the
desert) the wind is the primary erosion
factor. The wind picks up small particles of
sand and hurls it through the air and smacks
it into rock, which breaks off small particles.
