Artic climate, very cold

Permafrost, Always frozen

Lickens small weeds moss

Around the north pole

Latitude: How far apoints from the Equator.

Depending of the human impact we can find differents types of landscapes:

-Natural landscapes. Are those without human impact

-Trasformed landscapes. Are those in whick agriculture and the use of fire have transformed the enviroment irreversibly.

-Ordered landscapes. Are theorecally create by a society actin in a rational and coherent manner.

Raw materials: everything that you can see before processing.

Primary sector comprises economic activities concerned fairly directly with raw materials.

Mining

Forestry

Cattle raising

Fishing

Agriculture

Secundary sector. Uses industrial processes to transform raw materials. Basic industry, making-machine... etc.

Basic industry (minerals)

Constumes

Goods

Industry

Terciary sectors. The terciary sector is services, isn't including another things relatied to the other 2 sectors. E.g. transports, comunication, education....
