4.1 Ocean Circulation

This review activity will help students familarise themselves with the effects of different types of ocean circulation - the movement of energy and matter around the earth. They need to understand the impact of oceans on climate and it helps them understand some  aspects of environmental systems which may be mentioned in resource booklets but are not explicitly in the syllabus such as the knock on effect on food production and the inter-relationship with El Nino or La Nina.

 Here is the handout to go with the presentation
