Astronomy Review - Gravity, Scale, Tides

What moon phases occur with spring tides?

• New moon and first quarter
• First and third quarter
• New and full moon
• Full moon and third quarter

What type of tide is represented in the picture?

• Neap tide because of the tidal bulges
• Spring tide because the sun and moon are working together pulling on Earth.
• Spring tide because of where the Earth is in its orbit.
• Neap tide because the sun and moon provide opposite forces on the Earth.

Why do we have tides here on Earth?

• We have tides because of how the moon's gravity pulls on different parts of the Earth.
• We have tides because the Earth's oceans move.
• We have tides only because of the sun's gravity pulling on Earth.
• We have tides because of how the Earth revolves around the sun.

Which type of tide is represented in the picture?

• Neap because the sun and moon are working opposite each other.

• Neap because of the tidal bulges.

• Spring because the sun and moon are lined up and working together.

• Spring because that is where the Earth is its orbit.

• Third and full moon

• First and third quarter

The sun has more mass than Earth. Why doesn't the moon orbit the sun instead of Earth?

• The moon is closer to Earth than the sun so its gravitational pull is more.
• It does orbit the sun because of Earth's orbit around the sun.
• The Earth has a greater mass than the sun.
• Earth's magnetic field is so strong it pulls the moon close.

Which set of objects has the greatest force of gravity between them?

• The bottom pair because the spheres have a greater mass.
• The bottom pair because the spheres are closer together.
• The top pair because the spheres are further apart. 
• The top pair because the spheres have a smaller mass.

What are tides?

• Daily changes in ocean water due to the gravitational pull of the moon and sun on Earth.
• Daily push of the Earth on the ocean water.
• Daily changes in sea level due to the gravitational pull of weather patterns over Earth.
• Daily changes in ocean water due to how the planets line up in the solar system.

Both the Moon and the Sun influence the tides on Earth. The moon has a much greater influence though. Why is that?

• because the Sun is much less dense

• because the Sun is gaseous, not solid

• because the Sun is so far away from Earth

• because the Sun is less massive than the Moon

As the planets have larger orbits, what happens to their orbital speed around the sun?

• The larger planets further from the sun have greater orbital speeds.

• The orbital speeds remain the same regardless of distance from the sun.

• The orbital speeds of the planets decreases as they get further from the sun.

• The orbital speed depends on numerous factors not just distance from the sun.
