The Tides

What is the primary reason for the occurrence of two high tides and two low tides on Earth each day?

• The Earth's rotation causes water to oscillate back and forth.

• The Moon's gravitational pull varies across Earth's surface, creating bulges on both the near and far sides.

• The Sun's gravitational force is the dominant factor in creating daily tides.

• The combined effect of Earth's rotation and the Sun's gravity.

How does the strength of gravitational attraction between two objects typically change as the distance between them increases?

• It increases proportionally to the distance.

• It decreases, becoming weaker at greater distances.

• It remains constant, unaffected by distance.

• It increases exponentially with distance.

What is the long-term consequence of tidal forces on Earth's rotational speed?

• Earth's rotation will gradually accelerate.

• Earth's rotation will eventually cease entirely.

• Earth's rotation will gradually slow down until one side permanently faces the Moon.

• Earth's rotation will become irregular, with unpredictable changes in speed.

What would happen to the Moon if it were to get too close to Earth?

• It would be flung out of Earth's orbit into deep space.

• It would merge with Earth, forming a larger celestial body.

• Earth's tidal forces would cause the Moon to break apart into fragments.

• Its rotation would speed up significantly due to Earth's proximity.
