6. Diameter (pole to pole) 7,900 miles Diameter (equator) 7,937 miles Circumference (poles) 24,860 miles Circumference (equator) 24,902 miles Mass 5973600000000000000000000 kg 5.9736 x 10 24 Average density 5540 kg/m3 Average distance from the sun 150 million kilometers Period of ration relative to stars (1day) 24 hours Solar Day 23 hr, 56 min and 4.1 sec Period of revolution (1 year) 365.242199 days Earth’s Physical Properties

7. Earth may look perfectly spherical from space, like a giant marble, but it actually isn't! Instead, our planet is wider around the equator because matter is forced out as Earth spins (just as you feel you are pushed right when your car turns fast to the left). We call this centrifugal force. The Earth does not stay the same shape however, and scientists have been watching Earth's equator as it shrinks and grows!

8. It actually takes the Earth 365.242199 days to completely rotate around the sun, that’s why we have to have leap year every 4 years! What would happen if we did not have leap year?

13. It was!!!

36. Theories on moon formation, Learn more: http://www.universetoday.com/47996/how- was-the-moon-formed/ http://www.universetoday.com/47996/how- was-the-moon-formed/

37. Five serious theories have been proposed for the formation of the Moon (not counting the one involving the moon made out of cheese) The Fission Theory: The Moon was once part of the Earth and somehow separated from the Earth early in the history of the Solar System. The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came. The Capture Theory: The Moon was formed somewhere else, and was later captured by the gravitational field of the Earth.

38. Five serious theories have been proposed for the formation of the Moon (not counting the one involving the moon made out of cheese) The Condensation Theory: The Moon and the Earth condensed together from the original nebula that formed the Solar System. The Colliding Planetesimals Theory: The interaction of earth- orbiting and Sun-orbiting planetesimals (very large chunks of rocks like asteroids) early in the history of the Solar System led to their breakup. The Moon condensed from this debris. The Ejected Ring Theory: A planetesimal the size of Mars struck the earth, ejecting large volumes of matter. A disk of orbiting material was formed, and this matter eventually condensed to form the Moon in orbit around the Earth.

39. The Ejected Ring Theory or sometimes called the The Giant Impactor Theory

44. 5 minute check April 23, 2014 Answer the following questions 1.How many theories are there on how the moon formed? 2.What theory is most believed, explain that theory? 10.110.1 - The student will demonstrate how the sun’s energy and the earth’s tilt cause the 10.210.2 - The student will explain the relative length of days and nights in different seasons. 10.10 - The student will distinguish between rotation and revolution.10.10 10.13 - The student will describe how gravity affects relationships between celestial objects.10.13

45.  23.5°  Since we are on an angle this causes us to have seasons. If we did not have a tilt we would have the same climate year round.

46. Solstice: The longest and shortest days of the year -the days when the sun is furthest from the Equator -December 21 st is the shortest day of the year -June 21 st is the longest day of the year

47. Equinox: The two days each year when the sun is directly overhead at the equator. - The beginning of autumn and spring -Approximately March 20-21 and September 21-22.
