Land Use PlanningLand use planning is an essential tool

for pollution control and prevention. Land use categories refer to the different socioeconomic activities in a certain area, the human behaviors they create and their effect on the environment. These activities take place at a local level but contribute to global processes, such as climate change.

Geological Relief (topology)

• Relief refers to the shape of the land and it is caused by many geological and geophysical phenomena:

The retreat of a glacier causes the formation of a plane.

Erosion can cause canyons and valleys.

Plates colliding cause mountains.

Plain

Glacial Retreat

Mountain Formation

1. Movement of the earth’s plates

2. Volcanoes

Mountain Formation - Orogenesis

Over time mountains change because of erosion.

Himalayas

Appalachians

Canadian Shield

Valleys are formed from erosion by rivers

Humans Contribute to the Transformation of Relief

• Construct roads

• Dig mines

• Build cities and towns

Terrestrial relief has a huge influence on human activities

• Sports – mountain climbing, skiiing

• River plains are very fertile soil for agriculture.

• Volcano bases are very fertile for agriculture.

• Rivers provide an excellent source of transport from the oceans into the interior of the country.

• Building and road construction must plan carefully around the shape of the land.

• Canyons, mountains and valleys are often very valuable tourist sites.
