Define rotation

The spinning of the Earth on its axis

When an object rotates on it's own axis

100

Define revolution.

Revolution is the movement of the Earth around the Sun.

When an object revolves or spins around another object

100

What two factors are responsible for the creation of the seasons?

The tilt of the Earth's axis and the revolution of the Earth around the Sun.

100

Does the moon make its own light? Explain your answer.

No, the moon does not make its own light. Sunlight is reflected off of the surface of the moon to illuminate it.

100

Define Equator 

an imaginary line drawn around Earth that divides the Earth into Northern and Southern Hemispheres

100
What force keeps the Earth in orbit around the Sun and the Moon in orbit around the Earth
Gravity
200

How long does a single rotation on Earth last?

24 hours

200

How long does a single Earth revolution last?

365 days or 1 year

Look at picture #1. What is the seasons in the Northern Hemisphere at Point D.

Spring.

200

How many days does it take to go from one New Moon to another New Moon? 

On average 28-29 days. One Lunar Cycle = 29 days

200

Define Axis 

An imaginary line that runs from the North Pole to the South Pole upon which an object rotates

200

What type of Tide is occurring in the picture below? 

Spring Tide

300

Which direction does the Earth rotate.

Counter-clockwise

300

What shape is the Earth's orbit.

Elliptical (oval)

300

What season is it in the Northern Hemisphere when it is spring in the Southern Hemisphere?

Fall

300

What moon phase is at position 4?

300

Define Hemisphere

a half of the earth, usually as divided into northern and southern halves by the equator

300

Which produces warmer temperature, Direct or Indirect sunlight? 

Direct Sunlight 

400

Which hemisphere is experiencing day?

Both Northern & Southern Hemisphere


400

Describe the motion of the Moon, Earth and Sun in terms of revolution

The Moon revolves around Earth, and the Earth revolves around sun

400

During which season is there the longest days? Why are days longest then?

Day length is the longest during the summer. Days are longest then because the Earth is tilted towards the Sun.

400

Which phases are waning?

6 & 8

400

Define Equinox & Solstice

Equinox- These are the days when the Sun is exactly above the Equator, which makes day and night of equal length

Solstice- One of the two times of the year when the most amount of daylight time or the least amount of daylight time is in a single day

400

Define Spring & Neap Tides

Spring: When high tides are a little higher and low tides are a little lower than average

Neap: When high & low tides are in their "normal" depth 

500

Explain the science behind Day & Night

When the Earth rotates around it axis, the half of the Earth that is facing the Sun is in day and the half that not facing the Sun is in night.

500

Referring to the picture, which section represents the following seasons: Summer & Spring

(Top, Bottom, Left, Right)


Summer: Left

Spring: Top

500

If the Earth's axis wasn't tilted (0o tilt), how would the seasons on Earth be different?

Seasons would not exist. All areas of the Earth would have similar climates.

500

June 4th has a Waxing Gibbous Moon, what moon phase will occur on June 11th?

Waning Gibbous

500

Define Umbra & Penumbra 

Umbra- the innermost and darkest part of a shadow (cone shaped)
