Vocab
an imaginary line passing through the center of a planet that the planets spins around
Axis
This EM wave is can be observed by the human eye, unlike other waves that are invisible to the natural eye.
Visible light
what direction does the Earth rotate and revolve around the sun?
Counterclockwise
How many moon phases are there and how long does it take the lunar cycle to complete?
8 phases. Roughly 29 days or 1 month or 4 weeks
Moon
An imaginary line forming a great circle around the Earth's surface, equidistant from the poles. It divides the earth into North/South hemispheres.
Equator
This EM wave is can be sensed by our skin in the form of thermal energy.
Infrared light
How long does it take for the Earth to complete 3 revolutions?
3 years, 36 months
What side of the moon are we able to see from earth and why ?
Nearside because the moon completes 1 full orbit around the earth and 1 full rotation at the same time.
This term is defined as the periodical rise and fall of the ocean surface due to the tidal force of the moon and sun
Tide
a natural body that orbits another body in space
natural satellite
Which EM wave has the highest wavelength
radiowaves
what seasons does an equinox occur and how does this effect the hours of sunlight/darkness?
which moon phase comes after full moon?
Waning Gibbous
How are the position of the sun and moon arranged during a spring tide and Neap tide? which tide results in a small tidal range ?
Spring tide - sun earth moon = straight line
Neap tide - sun earth moon = right angle
neap tide
one of two days in the year when hours of daylight and hours of darkness are at their greatest and least.
Solstice
what kind of lenses are used in the refracting telescope?
Convex lenses
Earth's Northern hemisphere is tilted towards the sun. Which solstice is occurring in the southern hemisphere?
Winter solstice
The position of the Earth, Moon, and Sun during a solar eclipse
The moon passes between the Sun and the earth. "Moon Sandwich"
Taylor and Jose pulled their boat onto the beach and went on a hike. When they returned, the beach was covered by water and the boat was floating offshore. What is the most likely explanation?
The water rose due to the high tide
occurs when the moon passes through Earth’s shadow
Lunar eclipse
Why are space telescopes important to space exploration?
They can capture a wider range of EM waves and avoid distortion from the Earth's atmosphere
what are the two main factors that cause seasons on Earth ?
Earths tilt on its axis and motion around the sun
Davis observes the Moon every 3 days for 15 days. During this time, he notices that the Moon appears different in the night sky. What causes these changes in the Moon’s appearance?
the position of the Moon in its orbit around Earth
high tide normally occurs during which moon phase?
Full moon and New moon
