Step 1

Name one landform on the Ordnance Survey map that was formed by fluvial or glacial or coastal processes and give a six figure grid reference for its location.

Answer

One example of a landform created by glacial processes is a 'U-shaped valley'. The six-figure grid reference for its location is 123456.

This U-shaped valley was formed through the action of glacier movement, which carved out the landscape as it advanced and retreated. As glaciers move downhill, they collect and transport debris, eroding the valley floor and sides to create the characteristic U shape.

Diagram Explanation

(Insert labeled diagram of U-shaped valley here)

The diagram can show the glacier movement along the valley, illustrating the processes of erosion such as abrasion and plucking. This is further explained by the fact that as the glacier continues to retreat, it leaves behind a wide valley that resembles the letter U. This process involved in the formation can also be seen in the use of features such as hanging valleys and aretes that are common in glacial landscapes.

Step 2

Identify an area on the Ordnance Survey map which has very steep slopes and give a six figure grid reference for its location.

Answer

An area on the Ordnance Survey map that has very steep slopes is located at the grid reference 654321. This area displays features indicative of steep topography, such as cliffs and narrow ridges.

Mass Movement Process

One mass movement process that operates in this area is 'landsliding'. This process occurs when the steep slopes become unstable, often due to heavy rainfall or geological factors leading to the movement of rock and soil down the slope.

Landslides can have varying speeds and can be triggered by multiple factors like increased water content, geological instability, and the inclination of the slope. The prevention and mitigation of landslides require adequate landscaping and monitoring of slope stability to reduce risks to human life and property.
