Which position must the moon be in to produce a solar eclipse?
Earth must be between the moon and the sun.
The moon must be in a direct line between Earth and the sun.
The moon must be in the first quarter, with Earth tilted on its axis.
Earth and the moon must both be tilted on their axes in the same direction.
Which is affected by how far an area of land is from the equator?
the frequency of tides
the number of daylight hours
the strength of gravitational pull
the side of the moon viewed from Earth
Where do Earth’s oceans bulge to produce tides?
only on the side facing the moon
only on the side opposite the moon
on both sides of Earth at right angles to the moon
on the sides of Earth directly facing and directly opposite the moon
Which event is most likely to happen?
neap tide
solar eclipse
lunar eclipse
summer solstice
When does a lunar eclipse occur?
when the shadow of the sun falls on the moon
when the sun’s light shows red on the moon
when the shadow of the moon falls on Earth
when the shadow of Earth falls on the moon
Which best describes how the ocean changes due to tides?
Strong winds move water horizontally to change ocean levels
throughout a day.
Air pressure changes over the ocean causing the water level to
change throughout a day.
Gravity causes water levels within the ocean to change at regular intervals throughout a day.
A dome of water from the deep ocean moves to shore, changing ocean levels throughout a day.
Which statement best explains the difference in climates at the equator, the middle latitudes, and the poles?
The tilt of Earth’s axis affects the amount of sunlight each region gets during all four seasons.
Magnetic fields determine how much iron is in layers of Earth’s crust in each region.
Gravitational pull changes the patterns of plant growth and falling leaves in each area throughout the year.
Weather patterns heat and cool the soil, water, and air differently in every aquatic and terrestrial biome on Earth.
Which is Earth’s path around the sun?
Earth’s revolution
Earth’s rotation
Earth’s spin
Earth’s tilt
When it is winter in the Northern Hemisphere, which season is it in the Southern Hemisphere?
fall
spring
summer
winter
How does the Earth′s atmosphere make it different from Mars?
It helps Earth sustain life.
It causes the seasons on Earth.
It helps people on Earth see solar and lunar eclipses.
It causes people on Earth to see phases of the moon.
An astronomer discovers a new planet that she thinks could support life similar to that found on Earth. Which conditions would most likely support life on this planet?
a moderate temperature, liquid water, and the presence of an
atmosphere
a warm temperature, liquid water, and the absence of an atmosphere
a cold temperature, liquid water, and the absence of an atmosphere
a moderate temperature, ice, and the presence of an atmosphere
How does the atmosphere contribute to Earth’s ability to sustain life?
The atmosphere blocks harmful ultraviolet radiation from the sun.
The atmosphere allows heat to freely leave, ensuring water remains on the planet.
The atmosphere creates a gravitational pull that keeps Earth within the sun’s orbit.
The atmosphere keeps harmful gases such as oxygen and carbon dioxide away from Earth’s surface.
What is the main reason Earth is the only planet in our solar system capable of sustaining life as we know it?
Earth has a liquid core.
Earth has an atmosphere.
Earth has magnetic poles.
Earth has liquid water on its surface.
Which is a difference between Earth and the outer planets?
Earth has a rocky solid surface, while the outer planets are mostly gas.
Earth has a moon, while none of the outer planets have one.
Earth is tilted on its axis, while the outer planets are not.
Earth has an atmosphere, while the outer planets do not.
Which statement demonstrates how space exploration has most benefited humans?
The components of lunar rock samples have been analyzed and documented.
Satellite images taken from space have allowed people to test the chemical components of the oceans.
Freeze-dried foods developed to feed astronauts in space have been mass-produced to be sold in supermarkets.
Technologies developed for the space station have allowed people to provide advanced water filtration and purification systems to at-risk communities.
Which explanation best explains why exploring other galaxies may be difficult?
Scientists are unsure of their locations.
They would take thousands of years to reach.
Spacecrafts would collapse under the air pressure.
Instruments would be unable to function because of the low
temperature.
Which celestial object is a natural satellite of Earth?
Apollo
Mars
Moon
Sun
What have scientists discovered by using technology such as the Hubble Space Telescope?
The Milky Way is the largest galaxy in the universe.
The universe has millions of galaxies that each contain solar
systems.
There are very few galaxies in the universe, and none contain solar systems like ours.
There are millions of galaxies in the universe, but none contain a solar system like ours.
Which discovery would most likely result from studies conducted on the International Space Station?
new uses for microwaves
new uses for radio waves
effects on the human body while living in space
understanding of changing weather patterns in space
Which is most likely responsible for the planets′ predictable patterns of movement in the solar system?
solar eclipses
Earth spinning on its axis
the sun′s gravitational pull
the moon′s gravitational pull
