Example Question #131 : 5th Grade Science
Which of these is a direct result of Earth's rotation?
One year is 12 months long.
One week is 7 days long.
One month is 29 days long.
One day is 24 hours long.
One day is 24 hours long.
The part of Earth facing the Sun will experience day time. The opposite side will be experiencing nighttime. The Earth's rotation on its axis determines daytime and night because of its location regarding the Sun. This rotation leads to a 24 hour day on Earth.
The Victoria State Education and Training department explains why this is true, "The Earth is one of several planets that orbit the Sun, and the moon orbits the Earth. The Earth is essentially a sphere, and the Sun is a nearby star, which is an unimaginably large ball of gas that radiates light and heat as products of nuclear reactions. The Earth orbits the Sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its axis, not its orbit around the Sun. The term 'one day' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time."

Example Question #1 : Reveal Patterns In Seasonal Appearance Of Stars
If you were to watch the night sky from dusk to dawn, you would notice starts rising from the eastern horizon. They will sweep across the night sky and set beneath the western horizon at dawn. Something interesting happens over time. If you were to look outside again a few weeks later, those same stars would disappear from your view. A new group of stars would take their place. In the winter months, stargazers in the Northern Hemisphere look into the night sky and see Orion the Hunter. The same spot in the summertime revels the stars of Scorpius. In the spring, the constellation of the Sickle of Leo, the Lion, is present. Finally, in the fall, the Great Square of Pegasus comes into view. Every season this same pattern takes place, and the constellations return to the skywatcher's view.
As our Earth whirls through space around the Sun, its motions cause night and day, the four seasons, and the passage of the years. The Earth completes a single turn on its axis, not in 24 hours, but 23 hours 56 minutes. As a result, the stars appear to rise, cross the sky and set four minutes earlier each night. The Earth does not merely stand in the same spot in space and spins but is always rushing eastward along in its orbit around the Sun.
What patterns in the stars do we notice when observing the night sky?
Stars appear year-round in the same location.
Constellations are single stars that can be seen in the spring and fall.
Constellations are groups of stars that are seen in summer and winter.
Stars appear seasonally and are not all visible for the whole year in a single location.
Stars appear seasonally and are not all visible for the whole year in a single location.
The patterns of stars in the sky stay the same, although they appear to move across the sky nightly. In a single location, the same stars or constellations are not seen nightly but instead seasonally. As the Earth revolves around the Sun, a variety of stars are visible because of the Earth's location in its orbit.

Based on this information, which constellation(s) will be visible next summer in the Northern Hemisphere?
Orion the Hunter
Great Square of Pegasus
Sickle of Leo, the Lion
Scorpius
Scorpius
The Earth completes its orbit around the Sun or its revolution in about 365 days total. As the Earth revolves around the Sun, the position of the Earth changes, and this creates the different views of the night sky. Day and night are caused by the Earth's rotation or spin on its axis. This rotation is what causes daylight and nighttime. As the Earth changes its position, the stars appear to move in the sky as well. The stars are stationary but seem to move in the sky. Each day the Earth travels further in its orbit, and a different part of the night sky is visible. The stars appear seasonally, so the pattern will remain the same. Scorpius will appear each summer in the Northern Hemisphere following this pattern.
Example Question #3 : Reveal Patterns In Seasonal Appearance Of Stars
Some stars and constellations can be seen in the sky all year, while others appear only at certain times of the year.

The stars
The Sun

Will the residents of the Southern Hemisphere see the same constellations as those in the Northern Hemisphere?
No, they will see only half of each constellation that the Northern Hemisphere sees.
Yes, they will see the same constellations but during a different season.
Yes, they see the same constellations at the same time.
No, they will never see the same constellations.
Yes, they will see the same constellations but during a different season.
NASA explains why those in the different hemispheres will both see the constellations but during different seasons, "We see different views of the Universe from where we live as Earth makes its yearly trip around the solar system. That is why we have a different Star Finder for each month, as different constellations come into view. Also, as Earth rotates on its axis toward the east throughout the hours of the night, the whole sky seems to shift toward the west."
Example Question #1 : Reveal Patterns In Seasonal Appearance Of Stars
Dev looked at the night sky through his telescope on the first night of each season (spring, summer, fall, and winter). Each night he started looking at the stars at the same time and the same location. He observed the stars for five hours each night. If the sky was clear of clouds on all four nights, which of the following did he most likely observe?
The patterns of stars changed and appeared to move across the sky.
Different groups of stars remained in the same place for each of the four nights.
The same stars would be in the same place on each of the four nights.
There were no groupings or patterns of stars on the first day of the season.
The patterns of stars changed and appeared to move across the sky.
