river tees - landforms

Question 1

important facts

Answer 1

• north east of england
• its source is high in the pennine hills

Question 2

upper course

Answer 2

• has a high force waterfall
• A resistant band of igneous rock (dolerite) cuts across the valley. Its resistance has led to the development of a waterfall. Underlying weaker rock (limestone) is undercut. Waterfall retreats upstream to form a gorge

Question 3

middle course

Answer 3

• it has meanders and Oxbow lakes
• As the River Tees starts to erode sideways (lateral erosion), it forms meanders. These can be identified in the middle course near Barnard Castle

Question 4

lower course

Answer 4

• it has meanders, levees and estuary
• The meanders in the lower course are much larger, and oxbow lakes have formed. In this area there are also levees which have formed when the river has flooded
• The River Tees has a very large estuary with mudflats and sandbanks which supports wildlife in the area. Sites such as Seal Sands are protected areas
