Planets, planet earth and landscapes

  1. 1. PLANETS PLANET EARTHLANDSCAPES ON EARTH
  2. 2. Origin of our solar system Our solar system was a mass of stelar dust that started to turn around, and when it concentrates, it turns into a very hot ball that is the sun, a star. The matter that is outside forms small balls that are our planets.
  3. 3. In our solar system, nine planets circle around our Sun. The Sun is in the middle while the planets travel in circular paths (called orbits) around it
  4. 4. Inner Planets: Closest to the Sun and made of rock. The are: Mercury, Venus, Earth and Mars.Mercury is the smallest and nearest planet to the Sun, so it´s veryhot.Venus is almost the same size as the Earth. It is the hottest planet.Earth is our planet and is the largest of all the four inner planets.
  5. 5. Outer Planets.They are the farthest away from theSun planets, made up of gases.They are very large. Jupiter is the largest planet. Saturn is surrounded by a ring made up of rock and dust. Uranus is surrounded by a small ring. Neptune The farthest away and the coldest. planet
  6. 6. If we compare the size of the Sun with the sizes ofthe Planets, we can see that the Sun is much bigger.
  7. 7. Asteroids are pieces of rock in the space.They have no ice and the Comets do have ice.
  8. 8. Comets are celestial bodies made of rock and ice that move around the space and the tail means that the ice is melting while they travel.
  9. 9. Galaxy and Milky Way. A galaxy is made up of million of stars. One of them is the Sun and many others have their own system.
  10. 10. The Earth is the planet where we live. Most of Thesurface is covered by water this is why is called: “ the Blue Planet” The land is made up with continents and islands. The water can be found in the seas, Oceans, rivers, lakes, ponds… The Earth is surrounded by a layer of air called the Atmosphere.
  11. 11. THE MOON The Moon is a satellite of the Earth. The Moon is much smaller than the Earth. There are many holes on its surface called craters. It does not give off light. It looks bright because it reflets light from the Sun.
  12. 12. DAY AND NIGHT The Earth rotation causes the changes from day to night. The sun does not move. The Earth moves around the Sun and on its axis. This is called rotation and it takes 24 hours, one day.
  13. 13. One completeThe Earth Rotation. The Earth orbits orbit takes the Sun. 365 days. This is called an Earth revolution or a year. Earth revolution causes the four seasons.To see the Earth rotation: www.youtube.com/watch?v=8Vmmv0gOfWw
  14. 14. The Sun is a star. Stars are like giant balls of fire.Life on Earth is possible thanks to the light and heat from the Sun
  15. 15. The Moon orbits the Earth. It takes28 days. This is called “lunar month” Full First Crescent Crescent Moon Moon Last quarter Moon quarterNew Moon New Moon
  16. 16. LANDSCAPES ON EARTH•
  17. 17. Inland landscapes: mountains and lakes
  18. 18. Inland landscape: a valley. It´s a plain land between mountains
  19. 19. Island: piece of land surrounded by water
