3. what do you think happens to ir and uv light?

other sources of energy
the electromagnetic spectrum
electromagnetic spectrum: today we will work with the i2 strategy - looking at an image and identifying things you \see\ and what you think they \mean\. use the image below of the electromagnetic spectrum. draw lines to things you see and what you think that means/illustrates?

Explanation:

1. The Earth's magnetic field is important as it protects the planet from solar wind and charged - particle radiation, which can damage satellites and affect power grids. It also helps some animals with navigation.
2. Visible light is the type of radiation that reaches Earth's surface the most. The atmosphere is relatively transparent to visible light.
3. Some infrared (IR) light is absorbed by greenhouse gases in the atmosphere, which contributes to the greenhouse effect. Ultraviolet (UV) light is partially absorbed by the ozone layer, protecting life on Earth from harmful high - energy UV radiation.

Answer:

1. Protects from solar wind and charged - particle radiation, aids animal navigation.
2. Visible light.
3. IR is absorbed by greenhouse gases, UV is absorbed by the ozone layer.
