Revolution
We use the Earth's revolution to measure what time frame?
One year
What natural event does the Earth's rotation cause?
The day/night cycle.
The Earth's tilt causes what natural event to occur?
Seasons
Name the only movement that the moon experiences.
Revolution
What is the main cause for the tides?
The moon's gravitational pull on the Earth.
Provide two examples: The _______ revolves around the ______.
Earth, Sun; Moon, Earth
How long does it take for the Earth to make one full rotation?
24 hours/ 1 day
What does it mean that the Earth has a tilt?
The Earth wobbles as it revolves and slants at an angle.
Describe a Spring tide and name the moon's position
Spring tides occur twice a month when the moon is in a straight line with the Earth and Sun (New Moon and Full Moon). The greatest differences between high tide and low tide occur during spring tides.
If the northern hemisphere (half of the Earth) is tilting towards the sun, what season is it in that part of the Earth?
Summer
How long does it take for the Earth to make one revolution?
365 Days/One year
What does the word rotation mean?
The spinning of Earth on its axis.
What is the angle in which the Earth tilts?
23.5 degrees
Describe a neap tide and name the moon's position.
Neap tides occur when the moon is perpendicular to the sun and forms a right angle (first quarter phase and last quarter phase). Neap tides have the smallest differences between high tide and low tide.
If the northern hemisphere (half) of the Earth is tilted away from the sun, what season is it in that part of the Earth?
Winter
What does the word revolution mean?
The movement of one object around the center of another object.
What is an axis?
The imaginary line through Earth that extends from the North Pole to the South Pole and is the center of Earth's rotation.
What is the term for when the Earth reaches its maximum tilt during its revolution around the sun and how many times per year does it occur?
Solstice; Twice
Name the phase and location of the moon during a lunar eclipse.
Full Moon; Sun --> Earth --> Moon
What is the Equator?
It is an imaginary line that runs around the center of the Earth; the Equator is the only place on the planet that receives 12 hours of daylight and 12 hours of darkness all year round.
How long does it take for the Moon to make one revolution?
27.3 Days (28 Days is acceptable).
Daily Double: Over time, is the Earth's rotation slowing down, speeding up, or remaining the same? Explain what will happen as a result of this phenomenon.
Slowing down; one day will last longer than 24 hours.
What is the term for when the Earth has zero tilt and how many times per year does it occur?
Equinox; Twice
Name the phase and location of the moon during a solar eclipse.
New Moon; Sun --> Moon --> Earth
Recite the order of the lunar cycle starting with the New Moon phase.
New Moon --> Waxing Crescent --> First Quarter
--> Waxing Gibbous --> Full Moon --> Waning
Gibbous --> Last Quarter --> Waning Crescent -->
New Moon.
