eas 1.4 - Earth Subsystem

  1. Earth - Third Planet from the Sun
  2. Earth - is the largest of the terrestrial planets
  3. Earth - It is the only known planet to support life
  4. Atmosphere, Climate, Water, Light, Sun - Why Earth is the best planet in the Solar System that can support life?
  5. Atmosphere - Oxygen is constantly put by plants and trees.
  6. Atmosphere - Is thick enough to prevent poisonous rays of radiation from getting through it.
  7. Climate - There is a moderate amount of carbon dioxide in the planet's atmosphere.
  8. Climate - The temperature on Earth does not go from one extreme to the other either
  9. Water - Other liquids contain poisonous elements.
    1. Water - can be found anywhere, in its three states (solid, liquid and gas)
    2. Light - Plants need sunlight in order to grow
    3. Light - Earth spins on its axis in a span of 24 hours
    4. Sun - To allow life to be created and to support it, earth receives the perfect amount of heat and light.
    5. Sun - gravity keeps earth in its orbit.
    6. Geosphere - It is consist of three major layers: core, mantle, and crust.
    7. Outer Core - 1400 miles thick and combination of iron, alloy, and nickel.
    8. Inner Core - about 750 miles thick and made up primarily of iron.
    9. Mantle - accounts the big volume of the earth
    10. Mantle - covers the core and lies beneath the crust
    11. Outermost Mantle - is cool, strong, and hard
    12. Innermost mantle - is hot, rock is not stable, soft, plastic, and flows slowly.
    13. Crust - outermost layer
    14. Crust - a thin veneer below a layer is soil and beneath the ocean water.
    15. Crust - composed almost entirely of solid rock
    16. Hydrosphere - It is the liquid water component of the earth which circulates among oceans, continents, glaciers, and the atmosphere.
    17. Ocean - makes up 71% of Earth
    18. Glaciers - cover about 10% of Earth’s land surface today.
    19. Atmosphere - mixture of nitrogen (78%), oxygen (21%), and other gases (1%) that surrounds Earth.
    20. Atmosphere - It supports life by regulating climate by acting as a blanket and filter, retaining heat at night and shielding us from direct solar radiation during the day.
    21. Troposphere - 10 km. from the earth’s surface
    22. Troposphere - Formation of weather
    23. Jet stream - are fast flowing, narrow, meandering air currents
    24. Tropopause - border between tropopause and stratosphere
    25. Stratosphere - 30km – 50 km from Earth’s surface
    26. Stratosphere - Ozone layer
    27. Mesosphere - The “middle layer”
    28. Mesosphere - 50km – 90 km above Earth’s surface
    29. Mesosphere - Coldest region of the atmosphere
    30. Mesosphere - The layer where most meteors burn up upon atmospheric entrance
    31. Mesopause - border between mesosphere and thermosphere
    32. Thermosphere - Sun’s radiation strips off
    33. Thermosphere - “Ionosphere”
    34. Thermosphere - 90km – 400km above the Earth’s surface
    35. Thermosphere - Occasionally seen is the aurora borealis and aurora australis
    36. Thermosphere - Many satellites actually orbit the Earth within thermosphere
    37. Exosphere - Topmost part of the atmosphere
    38. Exosphere - Composes of hydrogen and helium
    39. Exosphere - Thinnest region of the atmosphere
    40. Exosphere - 400km – 500km above Earth’s surface
    41. bios - life in greek
    42. sphaira - sphere in greek
    43. Biosphere - all about life. All of the microbes, plants, and animals can be found
    44. Biosphere - extends to the upper areas of the atmosphere where birds and insects can be found. It also reaches to dark caves deep in the ground or to the bottom of the ocean at hydrothermal vents.
