The Lithosphere
Definition – The outer shell of the earth made up of the crust and the upper mantle.
Comments – The lithosphere is where human beings live!

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.

Mountain Formation
1. Movement of the earth’s plates
2. Volcanoes

Mountain Formation - Orogenesis

Over time mountains change because of erosion.

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.
