Earth and the Solar System Workshop Review Game

Earth and the Solar System PFA Workshop

​The Length of a year on Earth is a little over 365 days.

​A YEAR is defined by:

• How long it takes for a planet to move around the Sun

• It moves around the Sun because of the Sun's gravitational pull.

  This action of completing a lap around the sun is called a revolution.

Multiple Choice

What is the best definition for a year on Mars?

• The amount of time it takes for Mars to revolve around the Earth

• The amount of time it takes for the moon to revolve around Mars

• The amount of time it takes for Mars to revolve around the Sun

• Mars does not have years because it does not have an axis. 

Multiple Choice

What is the correct order of planets that will complete a revolution around the Sun, from FASTEST to SLOWEST?

• Earth - Mars - Jupiter - Neptune

• Mars - Earth - Jupiter - Neptune

• Neptune - Jupiter - Earth - Mars

• Jupiter - Mars - Venus - Earth - Neptune

​Properties of the Sun

• ​The sun is a ball of gas made of Helium (He) and Hydrogen (H).

• ​These two chemicals go through constant chemical reactions to create energy (Nuclear Fusion)

  • That energy travels through space in every direction - eventually getting to us!

• The Sun's high mass creates its high gravitational force. ​

Multiple Choice

What object in our Solar System has the HIGHEST mass? How do we know this?

• Jupiter, because it is so large. 

• Mercury, because it is closest to the sun. 

• The Sun, because of its extreme mass. 

• The Sun, because of its large size. 

Multiple Choice

What force in space causes Solar Bodies to orbit?

• Strong Force

• Friction

• Neutral Force

• Gravity

​What is Gravity?

​GRAVITY is an invisible force that pulls objects towards something with high mass.

​

​Each of the following forms because of gravity:

1. ​black holes (from collapsed, dead stars)

2. planets (from gas, ice and dust)

3. stars (from atoms creating fission together in a high pressure place)​

​

​The greater the mass, the greater the gravitational force

Multiple Choice

Why do we have the various seasons on Earth?

• Earth's axis of rotation is tilted, so when a part of Earth is tilted to the sun, it has summer

• Earth's orbit is not a circle, it is an ellipse, so we are sometimes closer or farther from the sun

• The moon is a large object, and its gravity affects Earth. The effect of gravity causes seasons

• The sun may burn hot OR cold. When the sun is warmer, we have summer; when it is cold, it is winter. 

Multiple Choice

Why is the summertime warm in the Northern Hemisphere? (READ the answer choices carefully!)

• The hemisphere receives low amounts of direct light from the sun. 

• The hemisphere receives low amounts of indirect light from the sun. 

• The hemisphere receives high amounts of direct light from the sun.

• The hemisphere receives high amounts of indirect light from the sun.
