Geomorphic systems
Stage 6 content:
Processes, cycles and circulations connecting natural systems
- the processes, cycles and circulations connecting natural systems
- geomorphic systems, e.g. processes at tectonic boundaries, volcanic eruptions, soil formation, coastal and river processes, and cycles of weathering, erosion, deposition

Geomorphology: the study of landforms, their origins, evolution, form and distribution.
The lithosphere is the outer shell of the earth, consisting of soil and geological formations. The earth is made up of different section: the core, the inner core, the outer core and the crust. Study of the lithosphere is primarily concerned with the crust.
The two sets of forces which shape the earth’s crust are tectonic forces (continental drift and plate movement at a smaller scale), and gradational forces (weathering, erosion, deposition and mass movement).
Landforms can be shaped in a number of ways:
· By water – through the processes of hydraulic action, abrasion, and corrosion
· By wind – through the processes of abrasion and deflation
· By ice – through continual erosion and deposition, abrasion.
Define the following: hydraulic action, abrasion, corrosion, deflation.

Lithosphere group work - model making
Create a 3-dimensional model which will help to teach your classmates about the lithosphere. You must work in groups of no more than 3. You should refer to your text book and handouts to revise the information on your topic. Your 3-D model will need to include detailed labels, be neat and tidy, be roughly to scale and be colourful. When your model is complete, you will need to complete a 2 minute presentation to the class explaining what your model represents. You will be given a mark out of 10 for your presentation.
