The moon
Outer Space
Earth's Center
Earth's Surface
Which of these is caused by gravitational attraction?
Earth's tilt on its axis

In the Northern Hemisphere, which month has the longest hours of daylight?
December
June
March
September
Which of these is a force that is directed down toward the center of the object?

Which statement describes what is happening in the picture?
Earth's gravity pulls down on skydivers A and B, and also on the plane.
Earth's gravity is only at work on Skydiver A, because she is closer to the ground.
Earth's gravity acts o the falling skydivers but not on the plane as it moves forward.
Earth's gravity pushes up on the skydivers, preventing them from falling too quickly.
What keeps Earth moving around the sun?
The gravitational force of the sun alone.
The gravitational force of Earth alone.
The gravitational force of the moon and Earth.
The gravitational force of the sun and Earth.

January
April
July
October
The graph shows the average hours of daylight in Seattle, Washington, for the months of January, April, July, and October. Use the graph to answer this question: Which of the following patterns does the graph show?
There are more hours of daylight in winter than in summer.
There are more hours of daylight in summer than in winter.

Why are most stars only visible at night?
They are only out at night.
The sun's brightness blocks their light.
They are visible, but only on cloudy days.
Earth rotates too fast in the daytime to see them.
Eric observed the moon each night for four weeks. He took pictures of how the moon appeared each night. Below are two of Eric's pictures. Why does the moon appear different in the pictures?
Over the course of a month, different parts of the moon give off light.
Over the course of a month, the same side of the moon gives off light.
Over the course of a month, all sides of the moon are visible from Earth.
Over the course of a month, different parts of the same side of the moon are visible from Earth.
Why do the moon and the sun appear to be nearly the same size in the sky?
The moon is closer to Earth than the sun is.
The sun is closer to Earth than the moon is.
The moon and the sun have the same mass.
The moon and the sun have the same brightness.
Why do the Northern Hemisphere and the Southern Hemisphere have opposite seasons?
Earth's revolution around the sun brings certain parts of Earth closer to the sun.
Earth's rotation around the sun changes the amount of sunlight that reaches Earth.
Earth's tilt on its axis as it rotates in place causes sunlight to miss certain parts of Earth during different seasons.
Earth's tilt on its axis as it revolves causes sunlight to strike one hemisphere more or less directly than the other.
Which statement about the sun and other stars is true?
The sun is much larger than other stars, so it blocks our view of other stars during the day.
The sun is about as bright as other stars, but Earth rotates away from other stars during the day.
The sun is about as close to Earth as other stars, but the other stars do not produce as much light during the day.
The sun is much closer to Earth than other stars, so its brightness blocks the light from other stars during the day.
Suppose Earth were farther from the sun What would happen to the gravitational pull between Earth and the sun?
It would increase.
It would decrease.
It would disappear.
It would stay the same.
Kelly can see the constellation Gemini in the winter sky. By summer, it is no longer visible. Which statement explains why?
