Examine the 1:50 000 Ordnance Survey map extract below and the accompanying legend which is available at the back of the book and answer each of the following questions. The landscape shown on this map extract has been shaped by different physical processes, including river erosion, glacial erosion and weathering.

Carefully look at the map. A is showing an upland area, the colouring is brown and the contour lines are closely spaced and increasing by number. At B, we see a lowland area with green colouring and well-spaced contour lines. Which area is more likely to experience freeze-thaw action?
Here the action verb is ‘state’. This requires you to simply state the reason why freeze-thaw action is likely to occur at the site you selected in part (i) above.
