Why does the physical landscape of the UK vary from place to place? (a) GapFill

The UK's physical landscape is divided into two halves by an imaginary line known as the  Scottish BorderTees-Exe LineNorth-South DivideThames-Mersey Line.  The land to the north and west of the UK is an area of uplands made from igneous rocks such as   slategranitemarbleclay.  These rocks are resistant to weathering processes such as   rockfallsglaciationfreeze-thawabrasion. 

Igneous rocks are found in places such as  the Penninesthe Holderness Coastthe Thames Basinthe Grampians.  Igneous rocks were formed as a result of  aeolian (wind) activityerosional activitytectonic activityfluvial activity which comprised processes in the UK's past.  Glaciation also affected the north of the UK. Most has led to distinctive features in the landscape, where valleys often have  steep sidesnarrow floodplainsinterlocking spursa V-shape. 

The land to the south and east is formed from less-resistant sedimentary rocks, which were formed by sediment produced in rivers or at the coast.  These rocks are more easily weathered and eroded, as unlike igneous rocks, they have  jointsbedding planesair pocketsminerals.  This means the landscape is characterised by   rockfallsbare rockrolling hillssteep valleys.  The erosion and weathering also make these landscapes suitable for human settlement and human activities for a number of reasons, including the rich deep, soils found in river valleys, known as  siltsandscreealluvium.  Rich soils leading to farming activity were also formed as a result of glaciation depositing glacial till or boulder clay in  Londonthe Isle of WightKentEast Anglia.
