Why does the Earth warm up?

Why the Earth becomes warmer

Because the Sun heats our planet. Sunlight passes through the atmosphere and warms the surface of the Earth.

The ground and oceans absorb this heat and become warmer. Some of this heat goes back into space, but part of it stays in the atmosphere.

Gases like carbon dioxide and water vapor trap heat and keep the Earth warm. This is called the greenhouse effect.

Warm air becomes lighter and rises, while cooler air stays lower. This helps spread heat around the planet.

When too much heat is trapped, the Earth’s temperature slowly increases. This is known as global warming.
