A Texas scientist is researching climate in Buenos Aires, Argentina, which is located in the Southern Hemisphere. On the first day of their research, the scientist observes that the sun rises at 8:00 am and sets at 5:50 pm. There is daylight for less than 10 hours. On which of the following dates did the scientist most likely begin their research?
March 21
June 21
September 21
December 21
The sun is rising later because Earth is entering the part of its orbit where the tilt of its axis keeps the Northern hemisphere pointing _________ the sun. This causes the amount of daylight each day to _______, so the days will be ____________.
towards; increase; longer
towards; decrease; shorter
away from; increase; longer
away from; decrease; shorter
How soon will Kenny be able to ride his bike to school again in full daylight and be on time?
By January 1, when the new year starts.
By March 21, when the spring equinox occurs.
By June 21, when the summer solstice occurs.
Not until the following September when the new school year starts.
The gravitational pull of the moon has a ________ impact on Earth's ocean tides than the gravitational pull of the sun because the sun is ________ Earth.
greater; farther from
greater; closer to
lesser; larger than
lesser; smaller than
The effect of gravitational force on tides in Earth's oceans is stronger when the ________ are ________. The result is referred to as ________.
moon and Earth; not aligned; a spring tide
sun and Earth; aligned; a spring tide
sun and moon; aligned; a spring tide
sun and moon; not aligned; a neap tide
Suppose that Earth keeps rotating and revolving just as it does now, but the moon takes twice as long to revolve around Earth. Predict how this would affect the frequency of Earth's tides.
Daily tides would occur twice per day, but spring and neap tides would not occur.
Daily tides would not occur, but spring and neap tides would occur half as frequently.
Daily tides would occur twice per day, but spring and neap tides would occur half as frequently.
Daily, spring, and neap tides would not occur.
You and your friend visit a beach on the California coastline. At 6 am, it is high tide, with the moon directly overhead. Your friend wants to come back to see if they can find any sea stars or crabs in the tide pools that form during low tide. You know there are 2 high and 2 low tides every 24 hours along this coastline. When do you tell your friend to come back?
12 hours later
4 hours later
8 hours later
6 hours later
In order to be certain your ship and passengers will safely clear the bridge, it will be best to time the cruise, so your ship arrives during the ________. This is because the low tide will be much ______ when the sun and moon are ______.
crescent moon; higher; lined up
full moon; lower; lined up
full moon; lower; not lined up
quarter moon; higher; lined up
You planned to arrive at the port during the morning’s low tide, but you were delayed by a few hours. When will the next low tide occur?
About 6 hours after your originally scheduled arrival time
About 8 hours after your originally scheduled arrival time
About 12 hours after your originally scheduled arrival time
About 18 hours after your originally scheduled arrival time
Examine the tide predictions chart for February. Which of the following statements provides the best explanation for the tides occurring on February 12?
The sun and moon are directly aligned with Earth and are exerting a stronger gravitational force on the ocean.
The sun and moon are not aligned with Earth, and the forces they exert on the ocean are perpendicular to each other.
The sun and moon are moving out of alignment, so the combined gravitational force they exert on the ocean is decreasing.
The sun and moon are moving into alignment, so the combined gravitational force they exert on the ocean is increasing.
Cameron and Soli want to dock their boat along a rocky shore at about noon near La Jolla, California. They will camp for the night, and leave at noon the next day. They do not want to be stranded when the water level gets low during low tide. They are reviewing the tide predictions chart for February. Based on the patterns of tides, which dates would be ideal for the camping trip? Select all that apply.
February 1
February 7
February 15
February 19
February 21

Based on the diagram, ________ will experience the longest amount of daylight because it is closest to the _______.
Location 1; North Pole
Location 2; equator
Location 3; sun
Location 4; South Pole
Which statements describe a neap tide? Select all that apply.
Tide with the greatest difference between high and low tide
Earth, sun, and moon aligned
Tide with the smallest difference between high and low tide
Gravitational forces of the sun and moon on Earth are perpendicular to each other
Which of the following does not affect the seasons on Earth?
