Global warming is an increase in Earth’s global temperatures, likely caused by more greenhouse gases in the atmosphere.

Sea ice is formed, grows and melts into the oceans. Sea ice floats on the ocean surface and contains less salt than sea water as the salt is ‘pushed out’ of the ice structure.

Convection currents are the transfer of heat in a gas or liquid, caused by differences in density and temperature.

The long-term weather conditions in an area are known as the climate.

Climate engineers use technology as part of a large-scale intervention to alter the climate and limit the impacts of climate change.

Global climate change and the effects

Chemistry

In the Industrial chemistry unit, pupils will learn about chemical, industrial, environmental and economic factors of some large-scale chemical processes.

In the Carbon cycle and climate change unit, pupils learnt about the formation of sedimentary rocks and fossil fuels, and the impact of burning fossil fuels within the carbon cycle.
