Geology

-Layering determined by the differences in both chemical composition and physical properties

-On basis of chemical composition: earth has three layers:

  • core (dense inner sphere)

    • Radius 3500 km, 95% iron+ 5% nickel

    • Inner core (solid) we know it’s solid because both p-waves and s-waves pass through it

    • Outer core (liquid) we know it’s liquid because p-waves pass through it but s-waves cannot

  • Mantle (less dense) 2900 km made of rock-peridotite

    • Lower mantle 2400 km (solid)(bottom)

    • Asthenosphere 400 km (weak/

Nada especial

  • Hydroelectric: Water is held behind a dam forming a reservoir, then, the falling water released turns a giant turbine, that moves a generator producing electricity. China, Brazil, and Canada. Three Gorges Dam in Yangtze river, China.
  • Wind: Second most used renewable energy. It has two main drawbacks: The impact of the wind farm on the landscape and the birds killed by the turbines. China, the USA, Germany, and Spain.
  • Solar: We use the sun’s heat and light to produce electricity. Germany, Italy,

Teoria Geo

Traditional societies: similar to rural societies (in political, economic and cultural ways to those that existed before the industrial revolution. Also called pre-industrial.

– Most of them work in agricultural and livestock farming activities.

– Their production is based on survival.

– They manufacture the things artisanaly.

– A very stable and controlled behaviour (by religious and modal codes).

– Comunication between them and villages is very limited. Only few have the opportunity to travel or hear

RENEWABLE RESOURCES

Renewable resources, together with inexhaustible resources (sunlight, wind, salty water…) are fundamental because their existence and renewal depend on rational use. Examples are land and forests.

Fertile soil is one of the most important because agriculture and livestock form the basis of the global food supply, and overexploitation can use it up. Excessive use of pesticides, fertilisers and inappropriate crops make the soil less fertile, or make land disappear altogether (desertification,
