Each planet moves around the sun in a- a path the shape of a circle b- a path the shape of an ellipse c- a path the shape of a spiral d- similar sized orbits
What is a path the shape of an ellipse
100
The time required for the Earth to rotate once on its axis is called a- day b- night c- revolution d- eclipse
What is a day
100
Why do we always see the same side of the moon from Earth a- because its phases are constantly changing b- because its period of rotation equals its period of revolution c- because half of the moon is always in sunlight d- because the moon changes its position relative to Earth
What is because its period of rotation equals its period of revolution
100
The time when the sun is directly above the equator is called a- axis b- rotation c- equinox d- hemisphere
What is equinox
100
Spring tides and neap tides occur in patterns governed by a- changes in the force of the Earth's gravity b- the type of ocean currents near where the tides occur c- whether the gravity of the sun or moon exerts a stronger pull d- the relative positions of the Earth, moon, and sun (phases of the moon)
What is the relative positions of the earth, moon, and sun
200
The closer a planet is to the sun, a- the slower it travels around the sun b- the faster it travels around the sun c- the smaller the angle of its axis d- the greater the angle of its axis
What is the faster it travels around the sun
200
The Earth's rotation is a direct cause of a- lunar eclipses b- winter weather c- daylight and night d- the June Solstice
What is daylight and night
200
What happens when the moon is waxing a- the sunlit part we see appears to get larger b- the sunlit part we see appears to get smaller c- the sunlit part we see appears to stay the same d- the sunlit part we see appears to go away
What is the sunlit part we see appears to get larger
200
The time when the sun is farthest north or south of the equator is called a- tilt b- solstice c- season d- helisphere
What is solstice
200
When do the greatest tidal ranges occur a- spring tides b- neap tides c- high tides d- low tides
What is spring tides
300
The gravitational attraction between two objects increases if a- their volumes increase b- their volumes decrease c- the distance between them increases d- the distance between them decreases
What is the distance between them decreases
300
What happens in the seasons' yearly cycle on December 22 a- the beginning of winter in the Northern Hemisphere b- the beginning of spring in the Northern Hemisphere c- the beginning of summer in the Northern Hemisphere d- the beginning of fall in the Northern Hemisphere
What is the beginning of winter in the Northern Hemisphere
300
What happens when the moon is waning a- the sunlit part we see appears to get larger b- the sunlit part we see appears to go away c- the sunlit part we see appears to get smaller d- the sunlit part we see appears to stay the same
What is the sunlit part we see appears to get smaller
300
What happens during a total solar eclipse a- the shadow of Earth falls on the moon b- a thin ring of the sun shows through c- the moon completely covers the sun d- the moon is about the same size as the sun
What is the moon completely covers the sun
300
What is the daily change in the level of ocean water called a- a storm surge b- a tide c- a bulge d- a tidal bore
What is a tide
400
The gravitational attraction between two objects decreases if a- their masses decreases b- their masses increases c- their total area decreases d- their total area increases
What is their masses decreases
400
Seasonal changes depend on which of the following a- weather b- wind patterns c- equinoxes d- latitude
What is latitude
400
Why don't solar and lunar eclipses occur every month a- the moon's orbit is an ellipse b- the moon's distance from Earth changes c- the shadows do not line up correctly d- the moon's orbit is tilted
What is the moon's orbit is tilted
400
Annular solar eclipses occur because a- the moon reflects more sunlight than the Earth does b- the Earth's shadow is too small to completely cover the moon c- the moon is too far away from the Earth to completely hide the sun d- the moon, sun, and Earth are not lined up in a straight line
What is the moon is too far away from the Earth to completely hide the sun
400
What is the difference between levels of ocean water at high tide and low tide called a- a tidal range b- a neap tide c- a spring tide d- a tidal bore
What is a tidal range
500
What is an object's resistance in speed or direction a- gravity b- kinetic energy c- pressure d- inertia
What is inertia
500
Which of the following is a direct cause of daylight and night a- Earth's tilt b- Earth's sunrise c- Earth's seasons d- Earth's rotation
What is Earth's rotation
500
What causes the phases of the moon a- the relative positions of the moon, Earth, and the sun b- the tilted orbit of the moon c- the moons period of revolution just equals its period of rotation d- sunlight reflecting off Earth's surface
What is the relative positions of the moon, Earth, and the sun
500
How do planets move if they are closer to the sun a- smoother b- rougher c- slower d- faster
What is faster
500
Which statement explains why the moon's gravity is able to create high and low tides a- the moon is revolving more quickly than the Earth is rotating b- the moon is revolving more slowly than the Earth is rotating c- some parts of the Earth never face directly on the sun and moon d- the moon is revolving at the same speed that the Earth is rotating
What is the moon is revolving more slowly than the Earth is rotating
