River Tees
  1. Background information
    1. Located in the Northern England . The source starts at Cross Fell in the North Pennines and flows eastwards for 85 miles to reach the North sea.
    2. Landforms
      1. Upper Course High Force Waterfall- At the top of the water fall there is a very hard rock called Whin sill , which is the cap rocj. Below this lies softer rock such as limestone, sandstone and shale. Erosional feature
        1. Low force potholes- Also located in the upper course of the river in upper Teesdale. small pebbles become trapped in hollows of the rock. The river flow has caused the pebbles to swirl around in the hollow making it deeper
          1. Meanders- located in the lower course of the river close to yarm there is lots of meander. They are formed as the flow of the river has less energy on the inside of the bend therefore the sediment is deposited. Whereas on the side bend the velocity of the river is more so lateral erosion occurs there.
