Identify the true statement.

a. since the sun is much larger than the moon, its gravity is the biggest contributing factor to the tide-generating force.
b. the tide-generating force creates two bulges in the oceans on opposite sides of earth.
c. tidal reach means the farthest inland the water goes at high tide.
d. the tide-generating force is a combination of only two forces, the gravitational attractions of the sun and moon.

B. The tide generating forces creates two bulges in the ocean on opposite sides of the earth

Explanation:

centrifugal force, causes the oceans to bulge on the opposite side facing the moon. While the moon's gravitational pull is strong enough to attract oceans into a bulge on the side of the earth facing the moon, it is not strong enough to overcome the inertia on the opposite side of the earth. As a result, the world's oceans bulge twice once when they are on the side of Earth closest to the moon, and once when they are on the side farthest from the moon.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
