Some Earth Science used by Geography, made it go with World Geography and Cultures book unit 1

1. By Jack Garrity

3.  Physical processes shape Earth’s surface.
Understanding that Earth is part of a larger
physical system called the solar system helps
us understand how life on our planet is
possible.
 Earth’s physical systems are affected by
natural forces such as earthquakes and
volcanoes that can influence human activities
on the planet.

4. Earth is part of a larger neighborhood that has other
planets, moons, stars, asteroids, comets, and stars.

5. All objects that revolve around the Sun are part of our Solar System

6.  Revolve to move in a circular or curving course
or orbit.

7.  Girar

8. Our huge Sun’s (a star) mass (amount of matter) creates
gravity.

9. Gravity of the Sun keeps the Earth and other objects
revolving in an orbit around the Sun.

10. 8 planets revolve in an orbit around the Sun.

11. The 4 closest to the Sun are called Inner Planets.

12. The 4 farthest away are called outer planets.

13. The Asteroid Belt orbits between the two groups.

14. Jupiter is the biggest, 1321 Earths would fit inside Jupiter.

15. Mercury is the smallest, you could fit 16 Mercury's inside
Earth.

16. All the planets have moons, except Mercury and Venus.

19. Pluto was once a planet, but now called a Dwarf Planet,
along with Ceres.

20. The inner planets are called terrestrial planets, their
surface (crust) are solid and rocky.

21. The Outer Planets are Gas Giants, less dense.

22. The Outer Planets are Gas Giants, less dense.

23. The Outer Planets have Ring Systems.

25. The Outer Planets are like a miniature Solar System
with orbiting rings and many moons.

26. Saturn has at least 61 moons.

27. Thousands of asteroids, comets and meteoroids revolve
around the sun.

28. Asteroids are small, irregularly shaped, planet like objects
found between Mars and Jupiter in the asteroid belt.

29. Asteroids are small, irregularly shaped, planet like objects
found between Mars and Jupiter in the asteroid belt.

30. Comets, made of icy dust particles and frozen gases,
look like bright balls of fire with long tails.

32. Meteoroids are chunks or rock and iron that sometime
hit the Earth’s atmosphere.

33. Meteoroids are chunks or rock and iron that sometime
hit the Earth’s atmosphere.

34. Meteoroids usually burn up as they enter the Earths
atmosphere .

35. Sometimes they don’t and hit the Earth.

37. In 1908, a meteorite hit Siberia in Russia, flattening and
burning a huge forest.

38. The 1908 meteorite was 197 to 623 feet wide and
flattened 770 sq mi of forest.

39.  Las Vegas is 135.9 mi², so the meteor flattened a
forest 7 times bigger.

40.  Las Vegas is 135.9 mi², so the meteor flattened a
forest 7 times bigger.

42. The Earth’s surface is a complex mix of landforms and
water systems.

43. The Earth is not a perfect circle, it is more oval.

44. It is 24,900 miles wide at the Equator, and 7,930 wide
from pole to pole.

45. The surface of the Earth is classified into 4 big groups
called spheres.

46. 70 percent of our planet’s surface is water.

47. Oceans, lakes and rivers make up the hydrosphere.

48.  hydrosphere

49. 30 percent is land called the lithosphere.

50. The air that we breath makes up the atmosphere.

51. The atmosphere is 78 percent nitrogen, 21 percent
oxygen, with small amounts of argon and other
gases.

52. The biosphere is all places where bacteria, plants,
animals, or fish live on the planet.

53. The 7 Continents are the biggest landforms.

54. Mountains, plains and other landforms cover the
continents.

55. Mountains, and plains continue underwater as well.

57. Land under the Oceans is called the Continental shelf.

58. We measure how tall or deep something is by the
distance above or below the Oceans.

59. We measure how tall or deep something is by the
distance above or below the Oceans.

60. How tall or deep something is measured by the
distance above or below Sea Level.

61. Tallest landform?

62. Tallest landform? Mount Everest 29,028 feet above Sea
Level.

63. Lowest dry landform?

64. Lowest dry landform? Shore of the Dead Sea 1,349 feet
below Sea Level.

65. Lowest point on Earth?

66. Lowest part? Mariana Trench 35,827 feet below Sea
Level.

67. Lowest part? Mariana Trench 35,827 feet below Sea
Level.
