S3 Geog Relief(U5.5)

What are the two ways of showing relief on maps?

• Colouring and contouring

• Shapes and contouring

• Shapes and graphs

• Colouring and graphs

Which colour represents lowland?

• Brown

• Yellow

• Green

• Blue

What does contour lines show?

• river

• length

• steepness

• height

What is the vertical interval?

How to determine which slope is steeper?

• Spacing of contour lines (wider is steeper)

• Vertical interval (larger is steeper)

• Spacing of contour lines (closer is steeper)

• Vertical interval (smaller is steeper)

What is/are the properties of concave slope?

• It has a gentler gradient near the lower slope

• It has a greater gradient near the lower slope

• Its contour lines are closely spaced near the tip and widely spaced near the bottom

• Its contour lines are widely spaced near the tip and closely spaced near the bottom

What is slope Y?

What feature is slope $G_1-G_2$ (e.g. cliff)? 

How can we identify a cliff on contour lines.

• The contour lines are facing outwards

• The contour lines are very widely-spaced

• The contour lines are facing inwards

• The contour lines are very closely-spaced

How to distinguish between a valley and a spur?

• A spur has a steeper slope near the top and a gentler slope near the bottom and valley is the opposite

• A spur has contour lines pointed upwards

• A spur has a gentler slope near the top and a steeper slope near the bottom and valley is the opposite

• A spur has contour lines pointed downwards
