Effects of Sun's Energy on Earth

The video explains how the sun's energy affects Earth's weather. It covers the types of solar radiation: ultraviolet, visible light, and infrared. The journey of solar energy to Earth is described, highlighting its absorption by the Earth's surface and subsequent emission. The video also discusses how the ground and oceans absorb this energy, leading to weather phenomena like clouds and storms.

What happens to the air as the ground absorbs the Sun's energy?

• It warms up and rises

• It remains unchanged

• It cools down and contracts

• It becomes heavier and sinks

What happens to the ground's temperature at night?

• It increases
