Comparing the Sun, Earth, and Moon

The Sun What physical features do you notice? How does the Sun compare to the Earth and Moon? What does the Sun provide for the Earth? The Sun-photo courtesy of NASA https://www.youtube.com/watch?v=2HoTK_Gqi2Q

Physical Characteristics of the Sun Prominence Sunspots Solar Flare Sun’s Corona The Sun-photo courtesy of NASA Prominence- Sunspots- areas on the Sun’s surface that are cooler than the surrounding area. Sunspots fade, and new ones develop over time. Solar flare- solar storm which extends into space Corona- means “crown”, extremely hot area around the Sun’s surface.

The Sun -The Sun is the star at the center of our Solar System (only star in our solar system) -Made of Hydrogen and helium gases. -Sun could hold 1,000,000 Earths inside. -The Sun’s enormous mass creates enough gravity to pull in orbit the planets -The Sun’s mass also creates tremendous heat -The Sun has six layers: Core, - Radiative Zone, Convective Zone, Photosphere, Chromosphere, and Corona.

The Moon The moon Reflects the light of the sun It’s a satellite                      More images The Moon The moon Reflects the light of the sun It’s a satellite Revolves around the Earth every 28 hours Has little to no atmosphere Its made of rocks Has landforms such as mountains, craters and valleys No liquid water Less gravity than the Sun and the Earth Causes tides on Earth (4) Lunar landscape-photo courtesy of NASA

The Earth What physical features do you notice on the Earth? How do Earth’s physical features help support life? The Earth-photo courtesy of NASA https://www.youtube.com/watch?v=HCDVN7DCzYE

How do the Sun, Earth, and Moon compare to each other? How are they alike? How are they different? Photos courtesy of NASA. How do the Sun, Earth , and Moon compare to each other? How are they alike? How are they different?

I bet you know the answers! What causes day & night? Which one is bigger the earth or the moon? Where does the moon get its light from? What percent of the earth is always lit by the sun? How many stars are in our solar system? How many days does it take for the Earth to revolve around the sun? How many low and high tides on Earth every 24 hours? What causes your shadows to change direction during the day?
