The Solar System - Earth and Life Science
- 1. THE SOLAR SYSTEM Earth and Life Science
- 2. THE SOLAR SYSTEM • The Earth is not the only PLANET to orbit the Sun. • There are other planets and there are also MOONS. • Which orbit around the planets. The Sun, the planets and their moons are all part of the SOLAR SYSTEM. • THE SOLAR SYSTEM is made up of 8 planets, with the Sun at the centre. • There are 4 inner planets, which are the planets closest to the Sun. There are Mercury, Venus, Earth and Mars. • The 4 outer planets, which are furthest from the Sun, are Jupiter, Saturn, Uranus, and Neptune
- 3. CONSTELLATION OF STAR WERE INDENTIFIED BY ANCIENT CIVILISATIONS • The seasons were measured and predicted by farmers who observed the changing night skies. They knew that certain constellation or stars could only be seen at particular times of the year.
- 4. SUN • The Sun is a giant, glowing ball of hot gases mostly made of hydrogen and helium. It is the center of the Solar System, and all the planets orbit around it.
- 5. GALAXIES Our sun is 1 of trillions of stars in the universe. Stars are found in groups held together by gravity. A huge group of stars is called a galaxy. Our entire universe is made up of thousands of galaxies.
- 6. THE MILKY WAY Our Solar System is part of the “Milky Way” galaxy. (Terrestrial Planets) • Mercury • Venus • Earth • Mars
- 7. MERCURY On Mercury you weigh only 38% of what you weigh on Earth. Fastest orbiting planetPlanet nearest to the sun. One side of the planet can be 800 degrees Fahrenheit when the other can be - 280 degree Fahrenheit at the same time.
- 8. VENUS On Venus you weigh only 91% of what you weigh on Earth. Venus has 90 times the pressure of Earth. Venus has volcanoes like Earth and rotates in the opposite direction of Earth. One time there were oceans before they boiled away.
- 9. EARTH 23 hours and 56 min=1 Earth day (rotation) and 365 days=1 Earth year (revolution) Earth is warm enough to keep most of its water from freezing and cold enough to keep it’s water from boiling. Temperature is between -13 degrees Celsius and 37 degrees Celsius
- 10. MARS Air Pressure on Mars is the same as 30 km above the Earthi’s surfaceMars is in the form of ice.Evidence that water was there at one timeVolcanic history like Earth.It has the tallest mount of the planets (Olympus Mons)3x’s size of Mt. Everest.
- 11. OUTER PLANETS (GAS PLANETS OR JOVIAL PLANETS) Jupiter, Saturn, Uranus, & Neptune
- 12. JUPITER It is the largest planet in the Solar System, it has a Great Red Spot from a storm system eftat is more than 400 years old (It is larger than Earth) 9 hours and 54 min=1 Jupiter day (shortest elity) The pressure is so great that it would crush a spaceship.
- 13. SATURN 2nd Largest planet in the Solar System95 times more massive than earth. Saturn has the largest rings of any planet, the rings are made of icy particles. Most moons of any planet.
- 14. URANUS It was discovered in 1781, Uranus appears blue- green in color. It’s axis of rotation is tilted 90 degrees. Moons are named after Shakespearean plays and formed from other broken moons
- 15. NEPTUNE It was discovered in 1846. Neptune has visual belts of clouds, Its Interior releases thermal energy to its outer layers. Neptune use to be the 8th planet after Pluto until 1999.
