Seasons
True or False : Colder temperatures in winter are due to the Earth being farther away from the Sun.
False
What motion of the moon around the Earth is responsible for the moon phases we see?
Revolution/Orbit
True or False: Earth experiences three types of tides: high, medium, and low.
False
True or false: The two types of eclipses are solar and celestial.
False
Follow-up: What are the two?
What force keeps the moon in orbit with Earth, and Earth in orbit with the Sun?
Gravity
Seasons are caused by two things, what are they?
1. The rotation of the Earth around the Sun.
2. The tilt of the Earth on its axis.
What is the positioning of the Earth, Moon, and Sun during a New Moon?
Write or draw.
The moon is between the Sun and the Earth, so the the lit side is facing the sun and the dark side is facing Earth.
☀️ 🌕 🌎
What are the two special tidal patterns we have on Earth, due to the interactions between the Earth, Moon, and Sun?
1. Neap Tide
2. Spring Tide
How does a lunar eclipse occur?
Explain/draw
🌕 🌎 ☀️
Moon, Earth, and Sun are in a straight line where the moon is in Earth's shadow, can't reflect sunlight.
Earth's revolution takes how long?
365.25 Days
What season is the Northern Hemisphere experiencing when the top half is tilted away from the sun?
Winter
What phase of the moon would be seen from Earth?
🌕
🌎 ☀️
First Quarter Moon
What type of tidal pattern is experienced when the Moon is at a 90 degree angle from the Sun and Earth?
What is special about these tides?
Neap Tide
Weak Tides
How does a solar eclipse occur?
🌎 🌕 ☀️
Earth, Moon, and Sun are in a straight line where the moon blocks out part of the sunlight.
What is responsible for Earth's day/night cycle?
Why does is it warmer at the equator than at the North Pole?
The equator gets more direct sunlight.
What is the positioning of the Earth, Moon, and Sun during a Waning Gibbous?
Write or Draw
Earth is roughly between the Sun and Moon, but the Moon has moved slightly ahead in its orbit, so it is no longer a full moon.
🌎 ☀️
🌕
What tidal pattern is experienced when the Moon is either between the Earth and Sun, or opposite the Sun (other side of Earth) creating a straight line?
What is special about these tides?
Spring Tide
Extreme Tides
What is the umbra of an eclipse?
The darkest part of the shadow
All light from the Sun is blocked
If you're in the umbra, you see a total eclipse (total solar or total lunar)
What is the difference between rotation and revolution?
Rotation - When an object spins around its own axis
Revolution - When an object moves around another object in an orbit.
Why does the tilt of the Earth's axis cause summer to be warmer than winter in each of the hemispheres?
The tilt of the Earth on its axis causes the hemisphere to get more direct sunlight. More direct sunlight means higher temps. Less direct sunlight means lower temps.
Explain why we see the phases we do from Earth.
We see different phases of the Moon because of how sunlight hits the Moon (half lit, half dark) and how we view that illuminated part from Earth as the Moon orbits us, due to the angle.
What causes tides to happen?
1. The Moon’s gravity pulls on Earth’s oceans, pulling water toward it, creating a bulge of water (a high tide) on the side of Earth facing the Moon.
2. A second high tide forms on the opposite side because Earth is also being pulled slightly toward the Moon, water on the far side is “left behind,” creating another high tide on the opposite side of Earth.
So there are two high tides and two low tides each day.
What is the penumbra of an eclipse?
The lighter, outer part of the shadow
Some sunlight is still visible
If you're in the penumbra, you see a partial or penumbral eclipse
Interactions between the Sun, Earth, and Moon cause what 4 things to occur?
Tides, Seasons, Moon Phases, and Eclipses
