=__**Ch.1.7(Earth and the Sun)-1.8(Showing a Round World On A Flat Map)**__=
 * __1.7 Geo-terms:__**
 * 1) __Revolution:__ One round trip around the sun and back again.
 * 2) __[|Axis]:__ An imaginary line that runs from the North and South poles, through the center of the Earth.
 * 3) __[|Rotation]:__ The spinning movement of the Earth. (Currently spinning at 1,038mph.)
 * 4) __[|Tropic of Cancer]:__ The major line of latitude in the northern hemisphere.
 * 5) __[|Tropic of Capricorn]:__ The major line of latitude in the southern hemisphere.
 * 6) __[|Tropical Zones]:__ The space between the tropics and the equator.
 * 7) __[|Arctic Circle]:__ The most northern line of latitude.
 * 8) __[|Antarctic Circle]:__ The most southern line of latitude.
 * 9) __[|Polar Zones]:__ The area between the circles and the poles.
 * 10) __[|Temperate Zones]:__ Between the Tropics and their respected circles. (For example, Tropic of Cancer-Arctic Circle)


 * __T____he Moving Earth:__** Earth, along with all of the other planets, is having **rotation** with the sun, caused by gravity. It takes 3651/4 days to make one complete trip around the sun. The Earth is upon its **axis**, spinning, causing the different days we have. It takes 24 hours for one complete rotation of the Earth to complete a full day.
 * __Earth's Tilt Creates the Seasons:__** While the Earth is spinning upon it's axis and going around the sun, it is tilted, therefore, when it reaches a certain point, it is tilted in such a way that some parts of the Earth are receiving more sunlight than others, creating the seasons.

Tropics are the two major lines of latitude located in the Northern and Southern hemispheres. These are the **Tropic of Cancer** and the **Tropic of Capricorn**. Zones, or the **tropical zones**, are the distances between the tropics and the equator. The circles are located at the Earth's most and southern latitude lines. The circles are called the **Arctic Circle** and the **Antarctic Circle.**
 * __Tropics,Circles,and Zones:__** Earth is divided up into different areas called tropics,circles,and zones.
 * Polar Zones** are located between the circles and the poles.

__**Questions:**__
 * 1) How long does it take to make the Earth rotate once?
 * 2) What creates the Earth's seasons?
 * 3) Where are the polar zones located?
 * 4) **__BONUS QUESTION:__** Is the Earth really tilted, or is are we crooked on the Earth? (I don't know, so email me your thoughts at matthew.hanington@gmail.com)


 * __1.8 All Flat Maps Have Distortion:__**[| Distortion] on a map is where a map does not have things accurately shown. There are 3 different types of Flat Distortion Maps. One is where **Mercator Projection Map**, which shows the continents near the equator, but distorts the continents.



The **Eckert IV Projection Map** is one where it shows an equal-area map, but distorts places near the poles.



And the last one is **Goode's Homolosine Projection Map**. It shows the continents in perfect shapes, but distorts the oceans.
