Earth's Tilt
What is the angle of tilt of the Earth?
23.5 degrees
What are the four seasons?
Spring, summer, fall (autumn), and winter.
What are tides?
The rising and falling of the sea level.
What is gravity?
The force that pulls objects toward each other.
What is Earth's rotation? How long does it take for the Earth to complete one full rotation?
The spinning of the Earth on its axis. 24 hours (1 day).
How does the tilt of the Earth affect the amount of sunlight received?
It causes different areas to receive varying amounts of sunlight, leading to seasons.
How does the Earth's position affect weather in summer?
The Earth receives more direct sunlight, making it warmer.
What causes ocean tides?
The gravitational pull of the Moon and the Sun.
How does gravity affect the Moon’s orbit around the Earth?
Gravity keeps the Moon in orbit around the Earth.
What is Earth's revolution? How long does it take for the Earth to complete one full revolution?
The movement of the Earth around the Sun. 365 days (1 year).
What season occurs in the Northern Hemisphere when the North Pole is tilted toward the Sun?
Summer.
What happens during the equinoxes?
Day and night are equal in length.
What are the two types of daily tides that occur?
High tides and low tides.
Why does the Sun have a stronger gravitational pull on the Earth than the Moon?
Because the Sun is much larger and has more mass.
Is spinning a basketball on your finger an example of rotation or revolution?
Rotation
How does the tilt of the Earth affect day length in different seasons?
Days are longer in summer and shorter in winter.
What happens during solstices?
The longest or shortest day(s) of the year.
What type of tide occurs during full and new moons?
Spring tides.
How does the gravitational pull of the Moon create tides?
It pulls water towards it, creating a bulge that leads to high and low tides.
Is a horse running around a track an example of rotation or revolution?
Revolution.
Why is the Earth generally warmer at the equator than at the poles?
The equator receives the most amount of direct sunlight year-round.
Why do we have different seasons in the Northern and Southern Hemispheres at the same time?
Earth's tilt causes different amounts of sunlight to hit the hemispheres.
What type of tides occur during a first or third quarter?
Neap tides.
Describe how the positions of the Earth, Moon, and Sun can predict tidal patterns.
The arrangement of the Earth, Moon, and Sun will cause spring or neap tides based on their positions.
Before clocks were invented, people used shadows to tell the time. How was this possible?
As Earth rotates on its axis, it causes day and night. When the Sun rises and as it sets, shadows move according to the position of the Sun.
