Multiple Choice

Name the planets in order from the one closest to the Sun

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

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

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

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

The Planets of our Solar System

We have 8 planets in our Solar System. Mercury, Venus, Earth, Mars, Jupiter, Neptune, and Uranus. Each planet is so unique in its own way, but some planets have lots of characteristics that they share. Today, we will talk about the two categories (groups)that make up our planets, as well as comparing Earth with the other planets, in regards to size, their surface, and their atmospheric condition.

There are 2 planet categories in our Solar System: Inner Planets vs Our Planets

• Inner planets are also known as the "terrestrial planets" are the 4 planets closest to the Sun: Mercury, Venus, Earth, and Mars

• Outer planets are also known as the "Gas Planets" are the 4 planets away from the Sun: Jupiter, Saturn, Uranus, Neptune

• These categories are also separated by the Asteroid Belt.

Multiple Choice

• Inner planets

• Outer planets

• Both

• Venus

Multiple Choice

Terrestrial planets

• Inner planets

• Outer planets

• Both

• Asteroid belt

Multiple Choice

Located between the inner and outer planets.

• Sun
• Asteroid belt
• Uranus
• Moons

Multiple Select

Which are the inner planets? (Choose all that apply)

• Mercury

• Venus

• Earth

• Mars

• Jupiter

Multiple Select

Which are the outer planets? (Choose all that apply)

• Mars

• Jupiter

• Saturn

• Uranus

• Neptune

The inner planets have lots of similar characteristics.

• They are relatively small compared to the Gas planets.

• They are warmer planets.

• They all have rocky, solid surfaces.

• Since they have a solid surface, even though they are the smallest planets, they are the most dense.

• When it comes to atmospheric conditions, all planets have unique conditions. Below describes the inner planet's atmospheric conditions:

• -Mercury: No Atmosphere (Too close to the sun)

  -Venus: Atmosphere is mostly made up of CO2 (Venus is also the hottest surface planet)

  -Earth: Contains mainly of Nitrogen (78%) and Oxygen (21%) (Only planet known to support life)

  -Mars: Very thin atmosphere, mostly CO2

• Mercury

• Venus

• Earth

• Mars

Multiple Choice

There are how many inner planets?

• 3

• 4

• 5

• 6

Multiple Choice

Which group are the most dense planets?

• Outer Planets

• Inner Planets

The outer planets have lots of similar characteristics.

• They are relatively large compared to the Rocky, inner planets.

• They are colder planets

• They all have gaseous surfaces. (You will not be able to stand on these planets)

• Since they have a gaseous surface, even though they are the largest planets, they are the least dense.

• When it comes to atmospheric conditions, all planets have unique conditions. Below describes the outer planet's atmospheric conditions:

  -Jupiter: mostly Hydrogen (H2) and Helium (He)

  -Saturn: mostly Hydrogen (H2) and Helium (He)

  -Uranus: mostly Hydrogen (H2), Helium (He), and Methane (CH4)

  -Neptune: Methane (CH4)

• *You do not need to remember the different atmospheric conditions.
