Types of slopes Flashcards
differentiate between endogenic and exogenic forces:
endogenic - forces which operate deep underground.
exogenic - forces operating above earths surface.
what are the different types of slope?
- primary slope
- Primary erosion slopes
- secondary erosion slopes
- Deposition slopes
How are Primary slopes developed?
they are formed from endogenic forces.
How are Primary erosion slopes developed?
They are developed from erosion of the land.
How are secondary erosion slopes developed?
developed from erosion of primary or primary erosion slopes eroding
How are deposition slopes developed?
formed from the deposition of weathered material, eg a sand dune, sand is the deposition.
slopes can also be classified by their shape, list them:
- gentle slopes
- steep slopes
- concave slopes
- convex slopes
how is a gentle slopes indicated on a topographic map?
contours lines are widely spaced.
how is a steep slopes indicated on a topographic map?
contours lines are closely drawn.
how is a concave slopes indicated on a topographic map?
contours lines are closely drawn at the top and widely spaced at the bottom.
how is a convex slopes indicated on a topographic map?
contours lines are widely spaced at the top and closely drawn at the bottom.
