A PPT in Earth and life Science

1. SOLAR SYSTEM is the gravitationally bound system comprising the Sun and the objects that orbit around it, either directly or indirectly.

2. SOLAR SYSTEM it is in constant motion, with the planets and their moons, comets, asteroids and other space objects revolving around the Sun.

3. The masses of the planets are also concentrated in the Gas Giant planets Jupiter, Saturn, Uranus, and Neptune.

4. The large mass of these planets comes from their absolute sizes, not their densities. The inner planets are by far the most dense.

5. TERRESTRIAL (Inner Planets) made of materials with high melting points such as silicates, iron , and nickel rotate slower, have thin or no atmosphere Mercury Venus Earth Mars

6. JOVIAN (Outer Planets) gas giants rotate faster have thick atmosphere

7. PLANET BIYO is a minor planet named after a Filipino teacher, Dr. Josette Biyo Planet 13241 Found in the Main Asteroid Belt between Mars and Jupiter

8. 1) MERCURY INNERMOST AND SWIFTEST PLANET ALBEDO 0F 6% DAYLIGHT & DARKNESS BOTH LAST 88 DAYS TEMPERATURE RANGE OF -300F TO 800F VERY LITTLE ATMOSPHERE

9. 2) VENUS SIMILAR IN SIZE, DENSITY AND MASS TO EARTH THICK CLOUD OF CARBON DIOXIDE SURFACE TEMPS OF 900F DUE TO GREENHOUSE EFFECT ATMOSPHERIC PRESSURE IS 90 TIMES THAT OF EARTH IF EARTH IS HEAVEN THEN VENUS IS HELL

10. 3 ) EARTH The Earth: A unique, habitable planet in the solar system There are only two major requirements for a planet to become habitable. The star should survive long enough for its planets to develop life which means a medium-mass star, such as the sun, can survive long enough for life to develop. The planet must be located in the Goldilocks Zone – a region in the universe where water could remain liquid. Being in the Goldilocks Zone indicates that due to the distance of Earth from the sun, the amount of heat and solar energy received is just enough to make the temperature of Earth neither too hot nor too cold.

11. 4) MARS WHITE POLAR ICE CAPS HAVE GREAT RIFT VALLEY VERY DRY PLANET REDDISH ROCK, SAND AND SOIL

12. 5) JUPITER 2 1/2 TIMES LARGER THAN ALL OTHER PLANETS COMBINED 1 DAY LASTS 10 HOURS DUE TO FAST ROTATION HURRICANE-LIKE STORM SYSTEMS WITH WINDS OF 1000 MPH - GREAT RED SPOT SURFACE OF LIQUID HYDROGEN OCEAN SOME MOONS [61] AS LARGE AS MARS

13. MOONS OF JUPITER DISCOVERED BY GALILELO 61 TOTAL MOONS CALLISTO GANYMEDE IO EUROPA

14. 6) SATURN 29 1/2 YEARS TO MAKE ONE REVOLUTION SYSTEM OF RINGS HIGH WIND SPEEDS 1000+ MPH

15. 7) URANUS SURROUNDED BY POLAR CIRCLING RINGS KNOWN AS THE GREEN PLANET METHANE IN ATMOSPHERE ROTATES ON ITS SIDE

16. 8) NEPTUNE TWIN PLANET TO URANUS BY POLAR CIRCLING RINGS KNOWN AS THE GREEN PLANET METHANE IN ATMOSPHERE ROTATES ON ITS SIDE

17. 9) PLUTO MAY NOT BE A PLANET BUT A TRANSITION BETWEEN COMET AND PLANET AVERAGE TEMP OF -350F LARGE DIRTY ICEBALL 248 YEARS TO ORBIT SUN

18. Minor members of the solar system 1) COMETS 2) ASTEROIDS 3 ) METEOROIDS

19. Minor members of the solar system COMETS Often compared to large, “ dirty snowballs ” Composition: Frozen gases Rocky and metallic materials Frozen gases vaporize when near the Sun Produces a glowing head called the coma Some may develop a tail that points away from Sun due to radiation pressure and the solar wind

20. Orientation of a comet’s tail as it orbits the Sun Figure 22.27

23. Minor members of the solar system ASTEROIDS Irregular shapes AND Origin is uncertain Most lie between Mars and Jupiter Small bodies – largest (Ceres) is about 620 miles in diameter Some have very eccentric orbits Many of the recent impacts on the Moon and Earth were collisions with asteroids

24. The orbits of most asteroids lie between Mars and Jupiter Figure 22.25

25. Minor members of the solar system METEOROIDS are called meteors when they enter Earth’s atmosphere are called as meteorites when they are found on Earth A meteor shower occurs when Earth encounters a swarm of meteoroids associated with a comet’s path
