Question

3/22
what are the effects of earth tides?
rise and fall of sea levels, changes in the shape of continents, and triggering of earthquakes and volcanic activity
shift in magnetic field, changes in the length of day, and alteration of animal migration patterns
increase in atmospheric pressure, changes in ocean currents, and formation of hurricanes
formation of tsunamis, changes in weather patterns, and disruption of satellite

Explanation:

To determine the effects of Earth tides, we analyze each option:

• The first option: Earth tides (due to gravitational forces) cause sea - level rise/fall (ocean tides are part of Earth tides), can slightly deform the Earth (including continents' shape changes), and the stress from tidal forces can trigger seismic and volcanic activity.
• The second option: Earth tides don't directly cause magnetic field shifts, day - length changes (on a significant scale related to tides) or animal migration pattern alterations.
• The third option: Earth tides are not linked to atmospheric pressure increase or hurricane formation.
• The fourth option: Tsunamis are usually caused by earthquakes/volcanic activity, not directly by Earth tides, and tides don't disrupt satellites or directly change weather patterns in that way.

So the first option is correct.

Answer:

A. Rise and fall of sea levels, changes in the shape of continents, and triggering of earthquakes and volcanic activity
