Okay kiddo, let me explain Walloon coal measures to you. You know how we get coal to make electricity, right? Well, a long time ago, there were huge forests in Australia that grew in swamps. As the trees fell into the swamps, they got covered up by water and mud, and over time, this turned into coal.
The Walloon coal measures are a special type of coal found in Queensland, Australia. They're called "measures" because they're divided up into different layers – like a cake. Each layer has different types of coal, from soft to hard.
The Walloon coal measures also have a special property – they produce a lot of gas when they're heated up. This gas can be used to make electricity or other things we need, like plastics. So, companies mine the coal and extract the gas to use it in different ways.
However, mining coal can have an impact on the environment, so it's important that companies follow strict rules and regulations to make sure they're not damaging the land or polluting the air and water.
So there you have it, Walloon coal measures are special layers of coal found in Queensland, Australia that can be used to make gas for electricity and other things we need. But we need to make sure we protect the environment when we extract them.
