2. MARIA (mah ree uh)
Dark ,flat areas of harden rock from huge lava flows
Lava flows occurred 3-4 billion years ago
The singular form of maria is mare

3. Craters Large round pits can be hundreds of kilometers across
Craters were caused by impacts from merorids
Chunks of rock or dust from space
Maria have relatively few craters this means the craters were formed on the moon’s early history

4. High lands
Some of the light –colored features you can see on the moon surface
The peak of the lunar highlands and the rims of the craters cast a dark shadows
The highlands cover most of the moon’s surface

5. Size & density The moon is 3,476 kilometers across
The moon’s density is only one eightienth as much as the earth surfaces
The moon’s gravity is about one sixth of earth

6. Temperature
At the moon’s equator temperature range from torrid 130C in direct sunlight to a frigid -170C at night
The poles are even colder
The temperature may vary so much because the moon does not have an atmosshpere

7. Water For years people thought the moons had no water
In 2009 scientist using data from several probes they found a thin layer of water in the moon’s soil
The total amount of water is very small

8. Origins of the moon
Scientists have suggested many possible theories of the moon’s formation
The theory most fitting the evidence is called the collision ring theory
About 4.5 billion years ago when earth was young the solar system was full of rocky debris scientists theorized that an object collided with earth
materials from the object and earth outer layer was eject to earth orbit

9. Gravity caused this materials to clump up and form the moon
