PhysicsriversGCSEAQA Created by: nimrahali12Created on: 30-10-16 17:18 The rivers long profile cross profile ? vary over its course 1 of 11 The path of a river as it flows downhill is called? a course 2 of 11 Rivers have an upper course (closest to source of river and? middle course ad lower course (closest to mouth of the river) 3 of 11 Rivers form? channels and valleys as they flow downhill 4 of 11 They erode the landscape - wear it down , then transport the material to? somewhere else where it is deposited 5 of 11 The shape of teh valley and channel changes along the river depending on ? whether erosion or deposition is having the most impact 6 of 11 The long profile of a river shows? you how the gradient changes over different courses 7 of 11 The cross profile shows? what a cross section of the river looks like 8 of 11 Vertical and lateral erosion change? The cross profile of the river 9 of 11 What does vertical erosion mean? This deepens the river valley , making it v-shaped. It's dominant in the upper course of the river 10 of 11 What does lateral erosion mean? This widens the river valley. Its dominate in the middle and lower courses 11 of 11
