Earth-Sun-and Moon Unit TEST

What are the two movements of the Earth

• Twist & Revolution

• Rotation & Revolution

• Revolution & Orbiting

• The Earth only has one motion

Why do stars appear to move from east to west in the night sky?

• Because the stars are moving

• Because the Earth revolves around the sun

• Because the Earth rotates on its axis from west to east

• They do not appear to move

Planets appear to move in the sky against the backdrop of

• other planets

• the sun

• the moon

• The stars

The geocentric model says what object is at the center of our solar system?

• the Earth

• The sun

• The stars

• The constellations

The heliocentric model says what is at the center of the solar system?

• The Earth

• The planets

• the Sun

• The stars

The imaginary line that runs through Earth's poles is its

• revolution

• rotation

• axis

• orbit

Which of the following is responsible for the pattern of day and night on Earth?

• the tilt of the Earth's axis

• the rotation of Earth on its axis

• Earth's revolution around the sun

• the revolution of the moon around the Earth

Earth has seasons because

• The moon exerts a gravitational force on it

• the relative positions of Earth, sun and the moon do not change

• its axis is tilted as it revolves around the sun

• it rotates on its axis as it revolves

How does the distance between two objects affect the force of gravity between them?

• The closer the two objects are to each other, the greater the force of gravity

• The farther apart the two objects are, the greater the gravity

• the distance between them doesn't affect the force of gravity between two objects

• The force of gravity is the same for all object regardless the distance between them

We weigh less on the moon because

• the moon is bigger and therefore the gravitational force is greater

• The mass of the moon is less therefore the gravitational force is less on the moon

• The moon and Earth have the same force of gravity
