question 27 of 32
during high tide in the bay of fundy, canada, the tide rises more than an inch per minute. which description best explains this difference?
a. as earth rotates, the moons gravity pulls on different parts of the planet.
b. variations in salinity and temperature transmit waves across the ocean.
c. underwater disturbances displace large amounts of water.
d. ocean water is driven by differences in water density.

Explanation:

Tides are primarily caused by the gravitational pull of the moon on the Earth's oceans as the Earth rotates. This gravitational interaction creates high - and low - tide patterns. Options B, C, and D do not describe the main cause of tides. Variations in salinity and temperature (B) relate more to ocean circulation patterns rather than tides. Underwater disturbances (C) can cause tsunamis or other water displacements but not regular tides. Differences in water density (D) are related to thermohaline circulation, not tides.

Answer:

A. As Earth rotates, the moon's gravity pulls on different parts of the planet.
