Examine the tide predictions chart for February. Which of the following statements provides the best explanation for the tides occurring on February 12?

• The sun and moon are directly aligned with Earth and are exerting a stronger gravitational force on the ocean.

• The sun and moon are not aligned with Earth, and the forces they exert on the ocean are perpendicular to each other.

• The sun and moon are moving out of alignment, so the combined gravitational force they exert on the ocean is decreasing.

• The sun and moon are moving into alignment, so the combined gravitational force they exert on the ocean is increasing.
