Greenhouse effect

Paragraph for class seven. 

Greenhouse effect

Greenhouse effect is a natural process that keeps the Earth warm. It happens when the sun’s heat enters the Earth’s atmosphere and some of it is trapped by gases like carbon dioxide, methane, and water vapor. These gases are called greenhouse gases. Without the greenhouse effect, our planet would be too cold for living things. But today, because of pollution and cutting down trees, too many greenhouse gases are being produced. This makes the Earth hotter than before, causing global warming. As a result, ice is melting, sea levels are rising, and the weather is changing. To reduce the greenhouse effect, we should plant more trees, use less fuel, and keep our environment clean.
