moon phases
The cycle begins with this phase.
What is New Moon?
The sun rises and sets each day, but never actually moves because of this.
What is apparent motion?
Tides are caused by the gravitational force of this body.
What is the moon?
What are the two important things that work together to create seasons?
What is revolution and tilt?
This force keeps objects in orbit.
What is gravity?
The approximate length of a moon cycle.
What is 28 days or a month?
This movement causes night and day.
What is rotation?
When one side of the Earth is experiencing a high tide, the opposite side is experiencing this type of tide.
What is high tide?
When the northern hemisphere is experiencing summer, this season is occurring in the southern hemisphere.
What is winter?
This causes the apparent motion of the sun.
What is the Earth's rotation?
When the shape of the moon you can see is getting larger.
What is waxxing?
The Earth is tilted 23.4 degrees on this.
What is its axis?
If you stayed on a beach for 24 hours, you would experience this many changes in tide.
What is four? high, low, high, low
On this day, a hemisphere is tilted most towards or away from the sun.
What is the equinox?
The earliest clocks used this to tell time.
What are shadows?
When the shape of the moon you can see is getting smaller.
What is waning?
The further a planet is from the sun, the larger it has of this.
What is revolution or orbit?
This type of tide happens when the placement of the moon provides the greatest pull, therefore creating higher and lower tides than normal.
What is a spring tide?
The seasons that a planet experiences is very dependent on its tilt. This planet must experience very extreme changes in weather based on its tilt.
What is Uranus?
This determines the amount of gravitational pull an object exerts.
What is mass?
This is the reason that people on Earth never see the dark side of the moon.
What is the rotation and revolution speed of the moon is exactly the same, 28 days?
This force keeps things in orbit. Without it, all bodies would just fly off into space in a straight line.
What is gravity?
If the Earth did not rotate, how long would it take to experience the transition from a high tide to a low tide?
What is one week?
This location experiences very little change in season.
What is the equator?
The definition of cycle.
What is a series of events that are predictable and regularly repeated in the same order?
