The Big Bang

Dive into the wonders of our Solar System, where we'll explore the nine planets, their moons, and other celestial phenomena like asteroids, comets, and meteors. Understand how these celestial bodies orbit the Sun in elliptical paths and interact with their gaseous atmospheres—except for Mercury and Pluto. Discover Earth’s movement in space, its axial tilt, and the implications for seasons and climate. Join us in a journey through space to understand the vast dynamics of our galactic environment, including global climate patterns and biomes.

Presentation Transcript

  1. The Big Bang

  2. Galaxies

  3. The Solar System and Beyond

  4. Solar sytem • Planets • Satellites • Asteroids • Comets • Meteors

  5. Nine planets: Terrestrial, Giant, Pluto • Similarities • Move in same revolution direction around sun • Orbits move in elliptical path • Each rotates on a rotational axis (same direction except for Venus and Uranus) • Ecliptic plane close to the Sun’s equator • All have gaseous atmosphere except Mercury and Pluto • Differences • Mass/Gravity • Revolution period • Temperatures/Distance from sun • Atmospheric composition

  6. The Sun • Less-than-average sized • 5500-6100° C (10,000-11,000° F) • Nuclear fusion of H into He • Earth only intercepts 1 two-billionth of the sun’s energy release

  7. The Planets

  8. The Earth in the Solar System

  9. Relative Distance

  10. Pale Blue Dot

  11. Movement of Earth • Galactic Movement (220 mY) • 560,000 mph • Revolution (365.25 days) • 33,000 mph • Perihelion (closest point) = 3 Jan • Aphelion (furthest point) = 4 Jul • Rotation (24 hours) • 880 mph @ 33° N

  12. Plane of the Ecliptic • Inclination of Earth’s rotational axis is 23½° • Parallelism: Earth’s rotational axis remains constant with relation to the stars • Polaris (North Star)

  13. The Seasons • Solstices and Equinoxes

  14. Lines Related to Earth Revolution • Arctic Circle (66.5° N) • Tropic of Cancer (23.5° N) • Equator (0°) • Tropic of Capricorn (23.5° S) • Antarctic Circle (66.5° S)

  15. Insolation and the Seasons

  16. Sunlight Incidence Angle

  17. Global Circulation Patterns

  18. Distribution Within Latitudinal Zones • ITCZ • Wet • STHP • Dry • Westerlies • Mid-latitude cyclone • Continentality • Gulf of Mexico • Poles • Dry

  19. Global Precipitation

  20. Global Precipitation Variability

  21. Global Climates

  22. Global Biomes
