DTHS: Jones' S-E-M system and Gravity

What is the best explanation for a gravity well?

• It is a well w/ water that is under the influence of gravity.

• It is a curvature of space determined by mass of the object

• It is a like a magnet pulling you down so you stay on Earth!

Which pattern causes the effect of the full, moon?

• Moon is at a 90 degree angle to the Earth and sun

• Moon is in alignment with the Earth and sun

• Moon is on the other side of the sun, away from Earth

• Moon is pulling less on large bodies of water on Earth

What position is the moon when there is a large range between high and low tides-so high tides are higher than normal and low tides are lower than normal?

• 1st Quarter moon

• Last Quarter moon

• New Moon

• Crescent moon

What causes the differences between a higher high tides and lower high tides seen in the 4 main phases of the moon ?

• The amount of water in the tide

• The mass of that body of water-ex: ocean versus a bay

• The gravity well changes b/c based on the position of the moon.

• The amount of people near that body of water

Which object has the greatest effect on tides based on the causes of gravity wells?

• The size of your car and the other cars on the road!

• Sun

• Earth

• Moon
