Solar System Formation Review

What layer of Earth is unique (only Earth has it) when compared with the other terrestrial planets?

• liquid hydrosphere

• gaseous atmosphere

• solid crust

• liquidish mantle

Why does Mercury have no atmosphere?

• gravity from the gas giants

• the chemicals on it react with gases

• high density of Venus

• higher gravitational pull of the sun

What is the correct order of the planets?

• Mars, Venus, Earth, Mercury, Saturn, Jupiter, Uranus, Neptune

• Earth, Venus, Mars, Jupiter, Neptune, Mercury, Saturn, Uranus

• Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune

• Mercury, Earth, Venus, Mars, Saturn, Jupiter, Neptune, Uranus

The most abundant (lots) elements in the Jovian planets are...

• Hydrogen and Oxygen

• Nitrogen and Oxygen

• Hydrogen and Helium

• Oxygen and Helium

Select two factors that caused the solar system to organize itself into two groups based on density - dense inner planets and the gas giants (less dense)

• Gravitational potential energy of the sun

• Planetesimals flattened into a rotating disk

• Solar wind from the sun

• Jupiter absorbed extra gas and dust from the solar system

The theory that explains the formation of the solar system is called....

• Nebulis Theory

• Nebular Theory

• Big Bang Theory

• Big Nebulon Theory

Even though we may not be able to see them, all of the ---------- planets have rings.

• Jovian

• Terrestrial

• Rocky

• Warm

Mercury has extreme temperatures between night and day because....

• it is so close to the sun.

• it has a very dense atmosphere.

• it's oceans are hotter.

• it has no atmosphere.

Select the two elements that are the lightest and least dense out of all matter.

• hydrogen

• helium

• nickel

• iron

• carbon

Located between the inner and outer planets also known as the frost line.

• Oort Clouds

• Asteroid belt

• Kuiper Belt

• Moon rings
