Continents

north America, south America, europe, africa, australia, asia, antartica

oceans

• Pacific Ocean: It touches the left side of the Americas and wraps all the way around the world to touch the right side of Asia and Australia.

• Atlantic Ocean: The giant "S" shape in the middle of the map. It sits right between the Americas on one side, and Europe and Africa on the other.

• Indian Ocean: right below India. It is caught in a triangle between Africa (to its left) and Australia (to its right).

• Southern Ocean: very bottom of the map, forming a ring of ice-cold water around Antarctica.

• Arctic Ocean: The smallest one sitting at the very top of the map, covering the North Pole.

Natural resources

• renewable

• non renewable

Renewable resources

• materials that are replenished naturally more or less within the same time period when they are used

• e.g - water and solar energy

Non renewable resources

• may or may not be replenished naturally , or the natural processes occur very slowly and takes such a long time that it is beyond the period used

• e.g - crude oil

Nature - centred view

• seen as valuable itself

• environment should be preserved

• protected and retained in its original state as far as possible

• use of physical environment should be minimised and even prohibited

Human centred view

• valuable because humans can obtain materials from it for their use and benefit

• motivated to find ways to extract natural resources for money

How to use natural resources sustainably

conservation and environmental footprint

Conservation

→ reduce our consumption

→reuse a product or material

→recycling turns used materials into new and useful ones

→ recover useful materials from the waste we produce

technological developments

• influence our ability to identify and make use of resources

• lead to discovery of more efficient uses of natural resources so that our environmental footprint can be reduced

• e.g solar power
