Earth
These two things causes the Earth's seasons.
What is the tilt of the Earth and the amount of direct or indirect sunlight we receive?
When the sun is highest in the sky and the day length is longest, we call it this.
What is a (summer) "solstice"?
It takes this long for the moon to revolve completely around the Earth.
What is 29.5 days or about a month?
These two things keep the moon in its orbit around earth.
What are gravity and inertia?
The data, or what is measured in an experiment.
What is the "dependent variable"?
The Earth is always tilted this way throughout the year.
What is the "same direction (23.5 degrees)"?
This is how the Sun's rays strike the earth
What is "Direct/Indirect"?
Seeing different amounts of the sunlit side of the moon on different days causes this.
What are "moon phases"? (and a repeating pattern)
The distance the earth is from the sun means _______ when referring to the seasons (Hint: It's kind of a trick question)
What is NOTHING!?!? Distance means NOTHING when referring to seasons!!!
A group of parts working together to create a complex whole.
What is a "system"?
Why we don't have an eclipse every month.
What is "the moon's orbit is tilted 5 degrees different than earth's orbit"?
During spring and fall, the sun's rays shine LEAST here.
What are "the poles"?
During this phase of the moon, we can see no light from the moon.
What is a "new moon"?
This is the variable we can change in a study.
What is an "Independent variable"?
This term is used to describe the phase of the moon when we see all of the lit side.
What is "full moon"?
The two ways the earth moves through space and what each causes on earth
What is "rotation on its axis/24 hours" and "revolution around the sun/1 year"?
This occurs when the moon moves between the sun and the Earth, blocking at least some the the sun's light.
What is a "solar eclipse"?
During this process, the moon moves through the Earth's shadow, and cannot be seen for a short time.
What is a "lunar eclipse"? And otherwise known as what moon phase?
The sun appears higher in the sky in Iowa during this time of year because of the tilt of the earth and Iowa is receiving the most direct sunlight.
What is "summer"?
As we see less and less of the lit part of the moon, we say that it is doing this.
What is "waning"?
This occurs during full or new moons and causes the greatest difference between consecutive high and low tides
What is a spring tide?
The reason we are able to see the moon at all
What is the "sun's light reflects off it"?
The rise and fall of ocean water every 12.5 hours is called this and it's caused by.
What are "ocean tides" and the "moon's gravity"?
The two factors that affect the force of gravity and the relationship between each and gravity.
What are "mass and distance. As mass increases gravity increases. As distance increases, gravity decreases"?
These occur during 1st and 3rd quarters and see the least amount of difference between consecutive high and low tides.
What are "neap tides"?
