How does the force of gravity from a massive object change as the distance from its center increases?

• It becomes stronger.

• It becomes weaker.

• It remains constant.

• It depends on the object's temperature.

What is the overall effect of a tidal force on an object?

• It causes the object to spin faster.

• It compresses the object.

• It stretches the object.

• It makes the object lighter.

Why does Earth experience two high tides and two low tides approximately every 24 hours?

• The Earth's rotation causes different parts of the Earth to pass through two bulges of water created by the Moon's gravity.

• The Sun's gravity is stronger than the Moon's gravity, creating multiple tidal effects.

• Earth's magnetic field interacts with the Moon's gravitational pull.

• Ocean currents and wind patterns cause the water levels to fluctuate.

What phenomenon causes the Moon to always show the same face to Earth?

• Earth's magnetic field

• The Moon's elliptical orbit

• Tidal locking

• Solar wind pressure

When do spring tides occur on Earth?

• During the first and third quarter moon phases.

• When the Moon is at its closest point to Earth.

• When the Earth, Moon, and Sun are aligned.

• When the Moon is at its farthest point from Earth.
