The Carbon Cycle and Water Cycle

Unlock the full lesson!

In this video, learn about how materials are cycled on Earth. We start with a look at decay and decomposers and how they help recycle materials through an ecosystem. We then look at the water cycle and the main processes of evaporation and precipitation before tackling some practise questions. We then look at the carbon cycle and the main processes of photosynthesis, respiration and combustion and how they affect CO2 concentrations in the atmosphere. We finally look at how humans influence the carbon cycle before tackling some past paper questions. The workbook is full of practise / revision material to help you master this topic!
