Chapter 5 Earth Moon and Sun

Any rock from space that land on Earth's surface is

• a meteorite

• a comet

• a satellite

• an asteroid

The force of gravity between two objects depends on

• mass and weight

• speed and distance

• weight and speed

• mass and distance

What happens at a spring tide?

• There is only one high tide each day.

• There is only one low tide each day.

• There is the most difference between consecutive high and low tides.

• There is the least difference between consecutive high and low tides.

The tendency of an object to resist change in motion is called

• force

• gravity

• inertia

• weight

Radios, televisions, cell phones, and wireless computer networks are examples of technologies that benefit humans. How are they beneficial?

• They transmit and receive signals with zero percentage loss.

• They use signals that do not require mediums to travel.

• They relay information without direct human interactions.

• They use low-energy radio signals.

Which force does not require contact and can act on objects from a distance?

• applied force

• friction force

• gravitational force

• tension force

What is the effect of gravity on the motions of objects in the solar system?

• Gravity keeps Earth tilted on its axis.

• Gravity helps the Moon rotate on its axis.

• Gravity helps the Moon reflect light.

• Gravity keeps Earth moving in an orbit.

A student drops four items into a magnetic field created by a magnet. The table shows the student’s observations. Which conclusion does the data support? Item | Observation ---|--- steel paper clip | attracted to magnet wood block | not attracted to magnet plastic cup | not attracted to magnet nickel key | attracted to magnet Mark only one oval. - The force acting on objects in a magnetic field is the same for all the objects. - The force on an object can be determined by the material of the object dropped into the magnetic field. - An object must be in contact with the magnet to respond to the force of the magnetic field. - An object produces a force that attracts the magnet, which changes the direction of the object.

• The force acting on objects in a magnetic field is the same for all the objects.

• The force on an object can be determined by the material of the object dropped into the magnetic field.

• An object must be in contact with the magnet to respond to the force of the magnetic field.

• An object produces a force that attracts the magnet, which changes the direction of the object.

Which force keeps the planets in their orbits?

• opposite

• normal

• magnetism

• gravity

The diagram shows the arrangement of the Sun, Earth, and Moon when the Moon is in the first quarter phase. How does the location of the Moon impact Earth?

• Neap tides will occur, causing a small difference between high and low tides of Earth's oceans.

• Neap tides will occur, causing a large difference between high and low tides of Earth's oceans.

• Spring tides will occur, causing a small difference between high and low tides of Earth's oceans.

• Spring tides will occur, causing a large difference between high and low tides of Earth's oceans.
