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:

black holes (from collapsed, dead stars)
planets (from gas, ice and dust)
stars (from atoms creating fission together in a high pressure place)

The greater the mass, the greater the gravitational force

due to gravity.

Objects in Space

Comet
- frozen
- non spherical
- orbits a star
Star
- High density, high gravity
- OUR star, the Sun, gives us heat energy

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.

Fill in the Blanks

At the red mark, if the arrows are the sun's rays, it will be what season?

Type answer...

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.

Fill in the Blanks

If it is spring for the Northern Hemisphere, what season is it in the Southern Hemisphere?
