The Greenhouse effect is a known cause of global warming but what is it, what can it cause and how exactly does it work?
The Greenhouse effect is a cause of global warming when sunlight enters the earths atmosphere but is not allowed to leave with all the gasses we let out of multiple gasses out of cars, power plants, factories and many more.
One of the layers of atmosphere around the earth is commonly known as the Ozone Layer and this is where the Greenhouse effect takes place. As the gasses rise, they are trapped inside the Ozone Layer, thickening the stratosphere.
This then also traps all the heat, some manage to leave the atmosphere and bounce back into space, but some dont, which then heats the earth twice as much.
That then melts ice by heating water around it. It also melts the ice by shining on it, like putting a block of ice under a warm lamp. Now imagine a cup with one block of ice in it, the ice melts but the water stays in the same place. Although if you put many blocks in the water then overflows dripping out of the cup. This is the same with the earth. Think that all this is caused by us polluting the air so heat is trapped.
Another well written explanation Kieran. Have you looked at the success criteria for the learning intention? Are you achieving it?
ReplyDeleteI like your analogy of the ice cubes.
very good paragraphing too.
