The Moon
The Moon takes approximately this many days to orbit Earth.
What is 27.3 days?
During this phase, the Moon’s visible side appears completely illuminated.
What is the Full Moon?
During this eclipse, the Moon moves between the Sun and Earth.
What is a solar eclipse?
This force pulls objects toward one another and helps keep the Moon in orbit around Earth.
What is gravity?
Our solar system is located inside this galaxy.
What is the Milky Way?
This term describes the point in the Moon’s orbit when it is closest to Earth.
What is perigee?
This word means that the visible illuminated portion of the Moon is increasing.
What is waxing?
During this eclipse, Earth moves between the Sun and Moon.
What is a lunar eclipse?
The gravitational pull of this object is primarily responsible for Earth’s ocean tides.
What is the Moon?
Spiral, elliptical, and irregular are three major types of these enormous collections of stars, gas, and dust.
What are galaxies?
This term describes the point when the Moon is farthest from Earth.
What is apogee?
This word means that the visible illuminated portion is decreasing.
What is waning?
A solar eclipse can occur during this Moon phase. (Hint it’s my favorite Twilight book #2)
What is a New Moon?
These tides occur when the Sun, Earth, and Moon are aligned and their gravitational effects combine.
What are spring tides?
When a small rocky object enters Earth’s atmosphere and produces a streak of light, it is called this.
What is a meteor?
The Moon’s orbit around Earth has this shape rather than being a perfect circle.
What is elliptical?
This phase comes immediately after First Quarter.
What is Waxing Gibbous?
During a total solar eclipse, this outer part of the Sun can become visible.
What is the corona?
These tides occur when the Sun and Moon pull Earth’s oceans from different directions, approximately at right angles.
What are neap tides?
If part of that object survives the atmosphere and reaches Earth’s surface, it receives this new name.
What is a meteorite?
We always see approximately the same face of the Moon because its rotation period matches this motion.
What is its revolution/orbit
Moon phases occur because, as the Moon orbits Earth, we see different amounts of this.
What is the Moon’s illuminated half?
Give the correct alignment for a lunar eclipse.
What is Sun → Earth → Moon?
Explain why Earth’s oceans usually have two tidal bulges rather than only one.
One bulge occurs on the side facing the Moon due to its gravitational attraction, while another occurs on the opposite side as part of the Earth-Moon system’s motion.
The observation that distant galaxies’ light is shifted toward longer, redder wavelengths provides evidence that the universe is doing this.
What is expanding?
