Multiple choice

  2. Stopping of oceanic currents

  3. Rise of the sea level

  4. Increase in the height of oceanic tides

D Correct answer
Explanation

If the Moon came closer to Earth, the gravitational pull on oceanic water would increase, causing higher tides. Tidal force is inversely proportional to the cube of distance, so a smaller distance means significantly stronger tidal effects. The temperature change (A), stopping of currents (B), and general sea level rise (C) are not direct consequences of the Moon's distance.
