QuestionAnswer
ecliptic plane the plane of Earths orbit
solstice the sun is overhead at its farthest distance either north or south of the equator
equinox Earths axis is perpendicular to the suns rays and at noon the sun is directly over head at the equator. Equal nights
synchronous rotation Earths gravity slowed the moon's original spin. The state of which its orbit and rotation periods are equal.
solar eclipse occurs when the moon passed directly between the sun and Earth and blocks the sun from view
apogee Farthest point in the moons orbit to Earth
perigee The closest point in the Moon's orbit to Earth
lunar eclipse occurs when the moon passes behind Earth in relation to the sun, and through Earths shadow.
seasons are caused by earths tilted axis
how much is Earths axis tilted 23. 5 degrees
The sun rises in the East
Sets in the West
moon, planets, and stars rise in the _______________ and sets in the _____________ East, West
time period from one noon to the next is called a solar day

solstices winter and summer
equinox fall/ autumnal equinox, spring/ vernal equinox
new moon moon is between Earth and Sun, side lit up by sun cant be seen.

waxing getting larger
waning getting smaller
How long does it take the moon to go through one lunar cycle about 29.5 days
what causes ocean tides the moon
spring tides higher; moon and sun are across from each other
neap tides lower; moon and sun compete, at a 90 degree angle
what causes the moon to change phases throughout the month movement around Earth
electromagnetic spectrum all types of electromagnetic radiation arranged according to wavelength and frequency
refracting telescope telescopes that use lenses to focus visible light
reflecting telescope telescopes that uses mirrors to reflect visible light
interferometry process that links separate telescopes so they act as one telescope, producing more detailed images.
albedo percentage of sunlight that is reflected by the surface of the moon.
highlands light-colored, mountainous, heavily cratered area of the moon, composed mostly of lunar breccias.
mare dark-colored, smooth plains on the moons surface
impact crater crater formed when space material crashes into the surface of a celestial body.

ray long trail of ejecta that radiates outward from an impact crater
rille valley-like structure that meanders across some regions of the Moon's maria
regolith layer of loose, ground up rock on the lunar surface.
what is the phase of the moon when the moon is between Earth and the sun new moon
when the moon appears to be getting larger, it is waxing
when the moon appears to be getting smaller, it is waning
what cause the moon to change phases thought the month. movement around earth
Earths moon orbits further away, is the biggest in comparison to its planet, and its mostly silicates.
what is the highest point in the sky that the sun reaches on a given day zenith
_____________ explains why the same side of the moon is always visible from Earth. synchronous rotation
The far side of the moon has many more ___________ than the other side highlands
the moons __________ is the amount of sunlight that its surface reflects albedo
A(n) ____________ can take place only when the moon is in the new moon phase Solar eclipse
Linking telescopes to improve the detail in the images obtained is called _______________. Interferometry
