What is the relationship between a planet's period of revolution and its distance from the Sun?
The shorter the distance between a plant and the su, the longer its period of revolution
The greater the distance between a planet and the Sun, the longer its period of revolution
The period of revolution changes as a planet moves away from the Sun
The period of revolution changes as a planet moves toward the Sun
How did Galileo’s observations support Copernicus’s ideas of a heliocentric solar system and NOT the accepted geocentric model?
He used a telescope to observe moons orbiting the planet Juiter
He observed how the constellations move across the night sky
He made careful observation of solar eclipse
He accurately measured the distance from Earth to the Sun
Earth is part of the galaxy known as the
Omega Centauri

Milky Way
Andromeda galaxy
Which statement best describes the differences between the inner planets and the outer planets?
The inner planets have thick, poisonous atmospheres, while the outer planets have no atmosphere at all
The inner planets are collection of foze gas and rocky particles, while the outer planets are fragments of rock
The inner planets are large, gaseous bodles, while the outer planets are small, asoild, rocky bodies
The inner planets are small, solid, rocky bodies, while the outer planets are large, gaseous bodies
Which of the following contains billions of galaxies?
Nebula
Universe
Solar system
Star
The Milky Way was created when a cloud of gas and dust began to condense. Near the center of the Milky Way, material is just beginning to condense into new stars. This indicates that the Sun is
Near the edge of the Milky Way galaxy, close to other stars that have already formed
Outside the Milky Way galaxy, close to other stars that are traveling through space
Near the center of the Milky Way galaxy, close to other stars that are just beginning to form
At the center of the Milky Way galaxy, close to dust and gas that has not yet condensed into new stars
What was used as evidence to develop the big bang theory and the origin of the universe?
The existence of planets revolving around stars other than the Sun
The existence of planets revolving around the Sun
The observation that stars are being produced in other galaxies
The observation that galaxies are moving away from each other
What is the size of Earth compared to Venus?
Earth is about the same size as Venus
Earth is about twice the size of Venus
Earth is about one-ninth the size of Venus
Earth is about nine times larger than Venus
A spiral galaxy
Has a bulging middle and arms that coil outwards
Is perfectly round
Is flattened and elongated
Has an undefined shape that is constantly changing
The size and shape of the universe is primarily controlled by
Electricity
Gravity
Friction
Magnetism
What do the observations suggest about scientific knowledge?
It can be changed without evidence based on scient’s opinions
It is always challenging and changed quickly if a mistake is found
It is always challenged by every generation of scientists
It can be challenged and changed with new evidence

What is the main difference between asteroids and meteoroids?
Meteoroids are generally bigger than asteroids
Asteroids are only found in the asteroid belt
Asteroids are generally bigger than meteoroids
Meteoroids are asteroids that have hit Earth
Ptolemy and Coperniucus were early astronomers. Ptolemy believed that Earth was the center of the solar system and Copernicus believed that the Sun was the center of the Solar system. Which model would the astronomers most likely use to support their beliefs?
Ptoemy and Copernicus would both use the geocentric model
Ptolemy would use the geocentric model and Copernicus would use the heliocentric model.
Prolemy would use the heliocentric model and Copernicus would use the geocentric model
Ptolemy and Copernicus would both use the heliocentric model

Appear not as large as the planet Jupitier
Exerts a strong electromagnetic force on them
Exerts a strong gravitational force on them
Is not in orbit around a black hole

They see many comets in the night sky
They watch it burn up and become a shooting star
They find space rock orbiting around Earth
They see many comets in the night sky
Jupiter takes 4,332 days to orbit the Sun, while Mercury takes 88days. Why is Mercury able to orbit the sun more quickly than Jupiter?
Mercury orbits much closer than Jupiter, so it feels the Sun’s gravity more intensely
Mercury orbits much closer than Jupiter, so it feels the Sun’s magnetic field mare intensely
Mercury has more mass than Jupiter, which causes Mercury to orbit faster
Mercury has more moons than Jupiter, which causes Mercury to orbit faster
