Part 2 Quit © Oxford University Press 2006 Landforms and exogenetic processes What are exogenetic processes? Exogenetic processes are the processes generated by agents, such as _______, ______ and ____. riverswindice They bring down materials from mountains which fill the valleys. Let’s take rivers as an example.
Part 2 Quit © Oxford University Press 2006 Landforms and exogenetic processes What are exogenetic processes? The two main processes are: Denudation Deposition Weathering Mass wasting Erosion Transportation Deposition

The Drainage Basin System
Higher Hydrosphere Drainage Basins[Date] Today I will: - Know what a drainage basin is - Be able to explain it in terms of inputs, processes or outputs.
Before break, we discussed watersheds and what constitutes a watershed. How do you think water moves through a watershed?
HYDROSPHERE By the end of the lesson you will be able to: 1.Describe the global hydrological cycle 2.Categorise the elements of the movement of water within.
1 HYDROSPHERE1 INTRODUCTION This unit has three components, The Hydrological cycle and its features. Working with hydrographs and Studying rivers.
The Drainage Basin System The Water Cycle. What Is It? The drainage basin of a river forms an integral part of the entire hydrological cycle. The drainage.

Drainage Basin. A drainage basin is the name given to the area of land which is drained by a river. The drainage basin acts as a funnel by collecting.
