Air pollution can be visible or invisible. Carbon dioxide is an invisible pollutant that is released into the atmosphere from combustion of fossil fuels.
Complete the pie chart from the table of data showing carbon dioxide emissions.
Water is constantly circulating around the Earth in a massive planet wide “water system” called the water cycle.

Use the words below to complete the paragraph to explain how clouds are formed. You will not need to use all words.
Evaporate, solid, gaseous, vapour, condense, liquid, sub-microscopic.
Water vapour in the air can
We call all the water on or near the Earth’s surface the hydrosphere.
Where are the five main stores of water on Earth?
About 0.65% of the water on earth is stored as groundwater. Some of the groundwater is stored in rocks.
Draw on the picture where ground water in rocks is stored.
Where does all ground water flow slowly towards?
In many places ground water is an important resource because it is a source of potable water.
What is potable water?
Human activities can contaminate groundwater stores. Sometimes contamination is caused by the sewage and waste from homes, which is managed by water companies.
The graph below shows the sewage and waste pollution in the UK by different water companies.
Which water company had 65 incidents per 10,000 km2?
How many incidents per 10,000 km2 did United Utilities have?
Some groundwater is stored in rocks. A student was interested in the permeability of different rocks and how this can affect the amount of water that they can store.
The graph below shows the mass of rocks before and after being put in a beaker of water.
Calculate the percentage change in mass of rock B.
Percentage change in mass = (change in mass ÷ initial mass) x 100
