As planets revolve around distant stars, they block some of the light from reaching the Kepler space telescope. The telescope measures changes in the brightness of stars as planets move in front of them. How has the Kepler telescope improved our understanding of the universe?
It has aided in the discovery of planets outside the solar system.
It has aided in the discovery of planets inside the solar system.
It has aided in the discovery of life outside the solar system.
It has aided in the discovery of life inside the solar system.
What causes the summer to be the warmest season?
The Earth’s tilt causes the shortest days with the most intense sunlight.
The Earth’s tilt causes the longest days with the most intense sunlight.
The Earth’s tilt causes the longest days with the least intense sunlight.
The Earth’s tilt causes the shortest days with the least intense sunlight.
What effect does this arrangement have on the tidal range?
The tide is larger than normal because the gravitational forces of the sun and moon pull in the same direction.
The tide is larger than normal because the gravitational forces of the sun and moon pull in opposite directions.
The tide is smaller than normal because the gravitational forces of the sun and moon pull in the same direction.
The tide is smaller than normal because the gravitational forces of the sun and moon pull in opposite directions.
Why are greenhouse gases important for sustaining life on Earth?
They keep the air clean.
They help keep Earth warm.
They help keep water moving on Earth.
They keep the wind from blowing too strongly.
Which force keeps the planets in orbit around the sun?
gravitational force
electrical force
magnetic force
wind force
Which best explains how Earth and the sun cause the seasons?
Earth’s continuous rotation on its axis creates the seasons.
The sun’s gravitational pull upon Earth creates the seasons.
The sun’s tilt as Earth rotates around it creates the seasons.
Earth’s tilt and revolution around the sun create the seasons.
Which describes the revolution of the moon, Earth, and the sun?
The moon and the sun revolve around Earth.
The sun revolves around Earth; both the sun and Earth revolve around the moon.
The moon revolves around Earth; both the moon and Earth revolve around the sun.
Earth revolves around the moon; both Earth and the moon revolve around the sun.
What would most likely happen to Earth if it were not tilted on its axis?
Most of Earth would experience winter all year long.
Most of Earth would experience summer all year long.
Most of Earth would still experience the change in seasons.
Most of Earth’s temperatures would be constant everywhere.
Which best explains why the Northern Hemisphere’s temperature is cooler in winter and warmer in summer?
The sun causes more evaporation in summer and less in winter.
The sun is lower in the sky in summer and higher in the sky in winter.
Earth is closer to the sun during summer and farther away during winter.
Earth is tilted on its axis causing some areas to receive more direct sunlight during summer and less during winter.
Which is most likely the cause of tides on Earth?
gravity
magnetism
solar storms
asteroid belt
How do the sun, Earth, and moon most likely affect tides?
Earth’s gravitational pull on the sun creates tides.
Earth’s gravitational pull on the moon creates tides.
The sun and moon’s gravitational pull on Earth creates tides.
The sun’s gravitational pull upon the moon creates tides on Earth.
Which gives the Hubble Space Telescope an advantage over telescopes on Earth?
its location
its being a natural satellite
its low cost of construction
its ease of accessibility for repairs
The illustration below shows the sunrays reaching Earth’s surface.
fall
spring
summer
winter
Earth’s distance from the Sun helps the planet sustain life. If the Sun were larger, what would MOST likely also have to be true for Earth to sustain life?
Earth would have to be further from the Sun.
Earth would have to be closer to the Sun.
Earth would have to be smaller.
Earth would have to be larger.
The National Aeronautics and Space Administration (NASA) is the agency responsible for the space program in the United States. What was the goal of NASA’s Apollo program?
to search for life on planets other than Earth
to land on a planet in another solar system
to determine the composition of the Sun
to send a human to land on the Moon
There are some towns located in the valley of the Alpine mountains. During part of the year, these towns stay dark all day because the mountains block the Sun. During which season would the Sun be low enough in the sky that the village stays in the shadows?
fall
spring
summer
winter
Which of the following is visible through a reflecting telescope?
planets around other stars
black holes in deep space
moons around Jupiter
surface of Saturn
Which characteristic is shared by Earth and the Moon?
glaciers
flowing water
an atmosphere that contains oxygen
an orbit created by the force of gravity
How does gravity support life on Earth?
by forcing Earth to continuously spin on its axis, which contributes to day and night
by causing changes in the distance between Earth and the sun, which contributes to the seasons
by keeping water and gases in the atmosphere close to Earth’s surface, which contributes to life processes
by preventing meteors and comets from hitting Earth’s surface, which protects living organisms from space fragments
Which contributes to Earth’s ability to sustain life?
The atmosphere allows all of the sun’s radiation to enter due to Earth’s distance from the sun.
The atmosphere prevents all space debris from reaching the surface due to the ozone layer.
The atmosphere is extremely thin due to the temperatures of the sun.
The atmosphere is breathable due to the unique mixture of gases.
Why are there high and low tides on Earth?
They are due to changes in the moon’s tilt on its axis.
They are due to the gravitational pull between Earth and the moon.
They are due to the magnetic force between Earth and the moon.
They are due to changes in the moon’s speed every month.
