THE SUN Presentation created by: Teresa Roe – Brandon Elementary 2010 Our star, the sun, is made of hot gases. It is the only star in our solar system. It is the major source of energy for our solar system. Sun as an Energy Source • Heat from the sun allows air to warm and rise. This is what produces wind. Sun as an Energy Source • Without energy from the sun there would be no water cycle. Sun as an Energy Source • The plants use the sun’s energy to help them make food. Without plants, there would be no animals. It produces many forms of energy including visible light. Visible Light • Our eyes use visible light in order to see the things around us. • Visible light from the sun contains all the colors of the rainbow. Ultraviolet energy being released from the sun UV Energy • The sun releases a lot of ultraviolet energy each day. This energy can cause you to have a sunburn. UV Energy • Some insects see by using the UV energy that is released from the sun. The sun releases large amounts of energy! Sunspots are cooler regions on the sun. The slightly cooler temperature makes them appear dark compared to the rest of the sun. The sun does have an atmosphere. It can only be seen during a solar eclipse. You can see it in this picture of a solar eclipse. Click on the picture to open NASA link. The earth is much smaller than the sun. The sun is the largest object in the solar system. It has the most mass. It’s gravity is stronger than anything else in our solar system. Sun’s Gravity • The Sun’s gravity pulls on all the planets. This forces the planets to continue orbiting the Sun. Our star is amazing!
