order the following times of year for the Northern Hemisphere from the hottest on the top to the coldest on the bottom.
1 six weeks after the summer solstice 2 the summer solstice 3 the Spring Equinox 4 the winter solstice 5 six weeks after the winter solstice
arrange the times of year based on the position of sunset, from farthest north on top to the farthest South on the bottom.
1 summer solstice 2 a week before the autumnal Equinox 3 a week before the spring equinox 4 winter solstice
what are the events by the length of time each take a, which the longest at the top and the shortest at the bottom.
1 the Earth orbit the sun once. 2 the Sun move through one constellation. 3 the Earth rotates once. 4 the sun rises and later sets.
how long does it take for the dates of eclipses to repeat?
18.6 years
what time will the waning gibbous moon day 19 be highest in the sky?
3am
foot on the following constellations that are considered part of the zodiac
Aries, sagittarius, virgo
on the Vernal and autumnal equinox, the sun rises due
East
select all the sources that correctly describes the equinoxes or solstices.
Northern hemisphere's summer solstice occurs when the sun is at its northernmost point on the celestial sphere, during the equinoxes, the Earth experiences daytime and night-time of equal length, equinoxes occur when the sun crosses the celestial equator.
magical Knox and Solstice to their descriptions.
The Equinox occurs in March and September in daytime and night-time of equal length, the solstice occurs in June and December there the longest or shortest nights.
what is a constellation?
a group of stars that form a fixed pattern in the sky, and an area of the sky for conveniently locating objects
as viewed from Earth, how did the stars appear to move relative to the north Celestial Pole?
counterclockwise around the Pole
select all the observations of the sky you might make over a course of a year.
different style or blocked out by the sun, the sun travels around the ecliptic once, the sun passes through all the signs of the zodiac
why would an astronomer living 5000 years ago probably recognized constellations visible in our night sky? The patterns
do not change appreciably over 5000 years
what are the choices that correctly describe equinoxes or solstices
during equinoxes the Earth experience daytime and night-time of equal length, the northern hemisphere summer solstice occurs when the sun is at its northernmost point on the celestial sphere, equinoxes occur when the sun crosses the celestial equator
select the statements that apply to a lunar eclipse
eclipses only occur when the moon is within 1% of crossing the ecliptic, the Earth's Shadow falls on the moon
the Sun appears to move along the celestial sphere on a line called the
ecliptic
the ecliptic is aligned on the celestial sphere. It
is the projection of the Earth orbit and the celestial sphere, and traces the path of the sun over a year
which part of Earth receives 24 hours of daylight for part of the year?
latitudes above 66.5 degrees north the Arctic Circle and latitude below 66.5 degrees the Antarctic Circle
which part of the earth receives 24 hours of daylight for part of the year?
latitudes below 66.5 degrees south the Antarctic Circle and, latitudes above 66.5 degrees north of the Arctic Circle.
the celestial sphere describes the position of stars in a way which makes the universe easier to comprehend. This is a good example of a scientific
model
what time of day will you see the first quarter moon rise across the horizon?
noon
select all choices that correctly describe the equinoxes or solstices.
on a solstice, the sun is the farthest it gets from the celestial equator. on the Spring Equinox, the sun is moving from below to above the celestial equator.
select all that describe the path of the sun in the sky if you are at a Latitude between 23.5 degrees north and 23.5 degrees south.
on some days, the sun can reach a point directly overhead., the Twilight. Is shorter than at other latitudes.
the sun rises due east and sets Due West
only on an equinox
the tilt of the moon's orbit shifts a little bit each year, which changes the dates of eclipses occur each year. This shift in the orientation of the plane of an orbit is called?
precession
the longest day day time of the year occurs on the summer
solstice
the light we see from phases of the moon comes from
sunlight reflected by the moon
select all the reasons why we do not have eclipses every month.
the Earth and the moon have orbits that are tilted compared to each other, the moon bypass above or below the Earth's shadow, the moon's orbit is tilted 5 degrees from the epliptic
usually the entire night side of Earth can see a lunar eclipse, but solar eclipse is our only seen in small areas and have been much faster. This is mostly because
the Earth's Shadow is much bigger than the moons
why is the moon teen as a waning crescent at the location labeled a and not a waxing crescent?
the Moon is moving counter-clockwise as seen in the diagram, and as it gets closer to the sun, the sun that portion is turning away from us.
the Earth still is responsible for which of the following?
the North Pole experiences daylight for 6 months, the Sun appears to move north and south on the celestial sphere over a year
the Earth still is responsible for which of the following?
the Sun appears to move north and south on the celestial sphere over a year. the North Pole Experience is daylight for 6 months
which celestial objects rise in the east and set in the west as seen from Earth?
the Sun, the moon, stars near the celestial equator
stars appear as points on the sky, some brighter than others. Why?
the brightness depends strongly on both how much light a star produces and how far away it is
why is the new moon more difficult to see from Earth than the full moon?
the illuminated hemisphere of the moon is facing completely away from us., it rises at the same time as the sun.
which of the following can happen during a total lunar eclipse?
the moon may appear dark red
every month, the moon passes between the Earth and the Sun new moon and on the opposite side of the Earth the Sun full moon. Why don't we see eclipses every month?
the moon's orbit is tilted.
stars appear as points on the sky, some better than others. Why?
the rightness depends strongly in both how much light a star produces and how far away it is
sponge all the statements that apply to the sun's path in the winter solstice in the northern hemisphere.
the sun rises in the Southeast, the sun's path across the sky is the shortest all year
select all the statements about the seasons that are correct
the sun warms the grandma directly in the summer, there are more daylight hours in the summer than in winter.
select all statements that apply to the sun's path on the winter solstice in the northern hemisphere.
the sun's path across the sky is the shortest all year. the sun rises in the southeast.
select the statements that apply to solar eclipses
they can be annular eclipses, partial eclipses occur more often than total eclipses, the moon's Shadow falls on Earth.
select all that apply to a total solar eclipse
this guy may become dark as night, the moon completely covers the Sun.
scientific models are
used to predict Behavior or outcomes, typically only useful over specific ranges of sizes or conditions, representations of nature
if the moon enters is waxing crescent phase tonight, then what lunar phase will you see in approximately two weeks?
waning gibbous
which of the following is not a complete name of a lunar phase?
waxing
which of the following are names of phases of the Moon?
waxing crescent, waning gibbous moon, full moon, new moon
of winter, spring, summer, and fall, if you are in Phoenix, Arizona, you would expect that a stick would cast the longest Shadow at noon during
winter
