What is gravity?
What is an invisible force that pulls objects together that have mass?

What is a solar system?
a group of planets, moons, asteroids, and comets that all orbit around a star.

What causes the Earth to experience different seasons?
The Earth's Tilt.

How does the redshift data support the Big Bang theory?
Redshift shows galaxies are expanding from the initial explosion

Explain how mass AND distance each affect the strength of gravity.
The more mass an object has, the stronger its force of gravity. The closer two objects are, the stronger the gravitational attraction between them.

If we increase the mass of an object, will it increase or decrease the gravitational pull?
increase the gravitational pull?

When the Northern or Southern Hemisphere is titled NEITHER TOWARDS OR AWAY FROM the sun, and winter just passed, what season is it?
Spring

The abundance of which two elements in the solar system provides evidence for the Big Bang Theory?
Hydrogen and Helium

Why don’t we experience a lunar eclipse every month if the Earth is positioned between the Moon and the Sun and every month?
Because the moon does not perfectly align with the Sun and Earth. Must perfectly be inside of the Earth's shadow.

If we decrease the distance between two objects, but also decrease their mass proportionally, what will most likely happen to the gravitational pull between the two objects?
Most likely the gravitational pull between them will stay the same or similar.

What is Gravity's role in the formation of the Universe?
Gravity pulled in matter together to form the first stars and galaxies.

What TWO reasons could explain why planets that are further away from the Sun have more moons?
1) Planets that are further tend to have more mass which results in stronger gravitational pull to capture debris to form moons. 2) Being further away from the Sun decreases the likelihood of the Sun capturing their moons.

What season is the Southern Hemisphere experience according to the image below and explain why?
Winter; the S. Hemisphere is the tilted away from the Sun.
