1. Planet Earth

2.  Hydrosphere  Lithosphere  Atmosphere  Biosphere  Continental Shelf

3.  Earth is part of our solar system, which is made up of the sun and all of the countless objects that revolve around it.  At the center is the sun- a star, or ball of burning gases. 109 times wider than Earth.

4.  The sun creates a strong pull of gravity that keeps all the planets revolving around it.

7.  Terrestrial planets- Solid, Rocky crust. -Mercury, Venus, Earth, and Mars. -Closer to the Sun Gas Giant planets- Gassy and less dense. -Jupiter, Saturn, Uranus, and Neptune. - Farther from the Sun

8.  Mercury and Venus are scalding hot.  Earth only planet that has liquid on surface.  Mars is a cold barren desert.  Jupiter, Saturn, Uranus, and Neptune are all gaseous so they are inhabitable.

9.  Asteroids- small irregularly shaped planet like objects.  Comets- icy dust particles and frozen gases that look like bright balls with long feather tails.  Meteoroids- space debris, chunks of rock and iron

10.  Hydrosphere- Water  Lithosphere- Land  Atmosphere- Air we breathe 6000 miles up  Biosphere- part of earth that supports life( people, animals, and plants)

12.  Continental Shelf- Part of the continent that extends underwater.

13.  Mount Everest- Highest point on the Earth located in South Asia. (29,035 feet)  Dead Sea- Lowest Point on dry land in South West Asia (1,349 feet below sea level).  Mariana Trench- Deepest part of Earth. Underwater Canyon located in the Pacific Ocean near Guam (35,827 feet deep).
