'Mobile Earth' is the title of this year's GA Physical Geography Competition.
It's now in its eighth year with a new sponsor, the British Society for Geomorphology.
The Earth is a flowing machine with earth materials constantly on the move from one place to another. This is just as true for the sky and the sea as it is for the land. Earth mobility happens on a range of scales, from a massive landslide (a mass movement) to tiny particles one by one (soil creep and suspended sediment); and from happening in an instant to movement that takes an almost unimaginable time (plate movement).
In geography lessons you will have learned a lot about the mobile Earth when studying erosion (which is the removal of material), but you will also have studied movement in the atmosphere (e.g. water cycle) and perhaps the oceans too (e.g. ocean currents). Now you will realise why the Earth is a flowing machine!
This year’s competition is about finding and taking a photo that captures an example that demonstrates the mobile Earth and the Earth as a flowing machine. Your image needs to show or convey movement of Earth material(s), or a landform or feature produced by materials movement, or evidence of a process or an agent that causes movement of Earth materials
The photograph needs to be accompanied with its (precise) location and up to 250 words that ‘show and tell’ the physical geography, describing the focus your example and explaining what it reveals and/or demonstrates about the mobile Earth, and how the movement happened.
Examples:
- Plant or tree roots causing upheaved soil or kerbstones
- Rock folds/rock faults (tectonic movements)
- River load or sediment
- Mud deposits
- Beach
- Sand dune
- Soil creep
- Slope collapse
- Landslips
- Landslides
- Glacial moraine, till or scree
- Slope with rocky boulders
- Rock face with sedimentary structures (e.g. fossilised dunes)
- Clouds
… and many more.
