Rivers 0.0 / 5 ? GeographyWater and riversGCSEWJEC Created by: Joseph15Created on: 14-12-15 11:46 93217568410 Across 1. a series of interlocking hills either side of a river, formed when it is forced to wind around hard rock which it lacks the energy to erode (due to low discharge). (12, 5) 4. a river’s load is thrown, sometimes at high velocity, against the bed and banks, wearing them down. (8) 5. raised banks each side of the river channel. (6) 6. a relatively shallow section of a river where the gradient steepens and water is fast and turbulent. (6) 7. a winding bend in a river that causes lateral erosion. (7) 10. Boulders and pebbles are rolled along the river bed at times of high discharge. (8) Down 2. The banks and bed of a river are worn away. The key type of erosion at this stage is abrasion and its dominant direction is lateral. (7) 3. Greater discharge at this stage means more energy, so the river can carry material including rocks, sands, silts and clay (the river’s load). (9) 8. a series of beds formed at the mouth of a river where the decrease in current causes deposition. The coarsest load is dropped first forming a flat topset bed, while silt and clay is carried further out to sea, forming foreset and bottomset beds. (5) 9. the low-lying ground adjacent to a river that is subject to flooding. (5, 5)
