- outside bend of a meander.

2) Find the arc-shaped area on the inside of the meander. Colour this yellow. Label what you think this feature is.

7) Draw a red arrow -----> to show where you think the fastest flow of water would be found, both before and after the tree branch.

8) Look at the photo below. Draw round the shape of the river's course with your finger. Draw the shape of the river's course on A4 paper.

9) Look at the photo below. Draw a site diagram on A4 paper, as accurately as possible. Label the following:

- left bank
- right bank
- fallen tree
- deposited pebbles
- erosion on the right bank
- area of deposition on the right bank
- area of erosion on the left bank
- overhanging plants.

The river flows from the bottom of the picture to the top, so the bottom is closest to the source. Draw an arrow and write: from the source.
