Unit 2: Space Systems Test Review

Seasons are caused by the tilt of the earth's axis, and:

• tides
• the earth revolving around the sun
• the moon's gravity
• wind

It is summer in New York. That means:

• The northern hemisphere is tilted towards the sun
• The southern hemisphere is tilted towards the sun
• The eastern hemisphere is facing towards the sun
• The western hemisphere is facing towards the sun

Shadows have different lengths throughout the day because:

• The earth is rotating
• The sun is revolving around the earth
• The earth is revolving around the sun

• axis
• rotation

• satellite

The __________ has planets, moons, comets, and asteroids.

Why does Earth have different seasons? 

• because of the distance between Earth and the sun 
• because of the speed of Earth as it rotates on its axis 
• because of the amount of light blocked by the moon on its axis 
• because of the tilt of Earth on its axis as it moves around the sun 

What happens when the area in which you live tilts away from the sun?

• It is summer.
• It is spring.
• It is winter.
• It is fall.

Why does a ball fall to the ground?

• Earth's force of gravity is GREATER than the ball's, so the ball gets attracted to the ground. 
• Earth's force of gravity is LESS than the ball's, so the ball gets attracted to the ground. 

What is the unit of measurement used to measure the distance of galaxies or stars?

• light year
• centimeter
• millimeter
• grams
