each line joins an area of an equal height.
the closer the lines, the steeper the slope
how can you determine height with colour?
green represents low-land.
brown represents high-land
what are four types of slopes
- Even Slope
- Concave Slope
- Convex Slope
- Compound Slope
how can you tell if its an even slope?
the contour lines are evenly spaced out
what is the formation of a convex slope?
the contour lines are close together(steep) at the base and spaced out(gentle) at the top
what is the formation of a concave slope?
the contour lines are spaced out(gentle) at the base and close togther(steep) at the top
what is the formation of a compound slope?
a compound slope has features of a concave and a convex slope
how are rural houses represented on a map?
they are represented be black squares
what are 3 types of settlement patterns?
- Linear
- Dispersed
- Clustered or Nucleated
what is a linear settlement?
multiple houses built along a road.It is often found on the approach into towns.
what is a clustered or nucleated settelement?
several house togther at a junction or bridging point. This was historically known as a ‘clachan’ (not built to a plan).
what is a dispersed settlement?
isolated houses, usually located in an agricultural area.
what three reasons are subjective to absense of settlement?
