Earth rotates on its axis once every ...
24 hours
True or False:
High Tide and low Tides happen in a relatively even flow daily.
True
Earth is tilted toward the sun, receives direct sunlight and there are more hours of daylight. What season is it?
Summer
What would happen if we didn't have tilt to the Earth?
Without the Earth's tilt, there would be no variation in the angle at which sunlight reaches different parts of the Earth throughout the year, resulting in a lack of seasonal changes in temperature and weather pattern
Explain the phase 'waxing crescent'
A waxing crescent moon occurs after the new moon phase when the illuminated portion of the moon is increasing but less than half, and it is followed by the first quarter moon phase.
The Earth's rotation causes _______ and ______.
day and night
How many tides each day and what are the intervals of high and low tides?
4 tide highs/lows per day, occuring every 6 hours or so.
Winter is colder because ________________.
The earth (specific hemisphere) is tilted away from the suns direct rays
How many days does it take to see all of the phases of the moon?
What is 29.5 days (or about a month)
Define orbit
An orbit refers to the curved path followed by an object, such as a planet, moon, or satellite, as it revolves around another object, typically due to gravitational attraction.
Define planet rotation
Planet rotation, or just rotation, is the circular motion of a celestial object around its own axis.
High tide and low tide happen how many times per day?
What is 2x or twice (2) per day?
The Earth's revolution around the Sun causes _______ because...
Seasons, because the earth's tilt and orbital position alters the intensity of the sun's rays changing the temperature and length of day
This diagram represents the four seasons. Name them in counter-Clockwise order based upon the location of the southern hemisphere (bottom ofearth)
Spring, Summer, Autumn, Winter
Which direction does the earth and moon orbit in?
Counterclockwise direction around the sun and earth respectively
Tides are at their peak highest and lowest during these moon phases because the pull of gravity is the strongest due to the combination of the moon and sun.
Full moon and new moon
What are the 8 phases of the moon?
New moon; First Quarter; Full moon; Last Quarter; Waxing gibbous; Waxing Crescent; Waning Gibbous; Waning Cresent
In this diagram, North America is experiencing winter because?
North America is on the side of the Earth not facing the Sun directly in this orbital position
Explain the main reasons for the seasons.
The main reasons for the seasons are the tilt of the Earth's axis relative to its orbit around the Sun, which causes varying angles of sunlight to reach different parts of the Earth throughout the year, resulting in changes in temperature and daylight duration.
Explain a total solar eclipse.
A total solar eclipse happens when the Moon passes directly between the Sun and the Earth, blocking the Sun's light and casting a shadow on certain regions of the Earth. Order is SME.
Explain what happens during a total lunar eclipse.
During a total lunar eclipse, the Earth comes between the Sun and the Moon and the moon falls into the Earth's umbral shadow, resulting in a darkening or reddening of the Moon as it passes through the Earth's shadow. Order is SEM.
During the first quarter moon, and the last (third) quarter moon the high tides aren't quite so high because of this?
What is the pull of gravity from the moon and the sun are working against each other.
Draw a labelled diagram of the earth, moon and sun and include:
- direction of orbit
- length of orbit

The make believe point at which the Earth rotates is called the ___.
What is an axis?
Explain if you could get another total lunar eclipse one week after a total lunar eclipse? Why/Why not?
A total lunar eclipse occurs when the Earth, positioned directly between the Sun and the Moon, casts its shadow on the Moon during a full moon phase. This alignment is possible only when the Moon is at or near the ecliptic plane (the plane of Earth's orbit around the Sun), which happens approximately every 29.5 days. Since this cycle is longer than two weeks, it's not feasible to have two total lunar eclipses consecutively within such a short timeframe. Next moon phase is third quarter and approximately 90deg further around the moon. No longer in the umbral/penumbral shadow.
