Space
Force that keeps a planet moving in orbit.
Gravity
This covers 70% of Earth's surface.
Water
Name the planets in order from the sun.
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
This used to be considered a planet, but is now categorized as a dwarf planet.
What is Pluto?
This band of rocks and dust travel in between the inner and outer solar system's planets.
Astroid Belt
This part of the Earth's interior has a liquid metal outer part and a solid metal inner part.
Core
The differences between terrestrial and gaseous planets.
Terrestrial planets are made up of rock (Mercury, Venus, Earth, Mars) and gaseous are made mostly of gas (Jupiter, Saturn, Uranus, Neptune).
What are the three things a celestial body needs in order to be called a planet?
1. It must orbit a star (the Sun)
2. It must have sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a nearly round shape
3. It must be big enough that its gravity cleared away any other objects of a similar size near its orbit around the Sun - This means that the planet has become gravitationally dominant — there are no other bodies of comparable size other than its own satellites or those otherwise under its gravitational influence, and Pluto shares its orbital neighborhood with Kuiper belt objects such as the plutinos
Layer of gas that surrounds a planet.
Atmosphere
Name three things that make Earth an inhabitable planet unlike the others.
1. Water
2. Oxygen
3. Atmosphere
4. Distance from the sun - seasons
This chemical makes Uranus and Neptune blue.
Methane
Which planet's axis is almost parallel to its orbital plane, making it spin nearly on its side?
What is Uranus?
Our solar system is part of this galaxy.
Milky Way
This part of the Earth's interior flows slowly but is mad of solid rock.
Mantle
This planet is 10 times the size of Earth.
Jupiter
This planet has the most moons at 82.
Name 4 other items in our solar system besides the planets.
2. Astroids
3. Comets
4. Moons
5. Rings
6. Dwarf Planets
How many tectonic plates are there on Earth and what happens when they collide or separate?
15
Magma rises and volcanos erupt forming new land forms like islands, earthquakes, large mountain ranges or trenches
This planet is named after the god of agriculture.
All planets are named after what type of gods?
What is the one exception?
