Question
[110]. Read the following passage carefully and answer the question.
Passage: Twice a day, the sea rises and falls along most coasts, a rhythm so regular that fishermen and sailors have planned their lives by it for centuries. The main cause is the moon's gravity. The moon pulls the ocean water on the side of the earth facing it into a bulge, and inertia creates a second bulge on the opposite side. As the earth rotates beneath these bulges, a coast passes through high water and then low water. The sun also pulls, strengthening tides when sun, moon and earth align and weakening them when they form a right angle. Tides are therefore not a mystery of the sea alone; they are a visible record of the earth, moon and sun moving together.
What is the main idea of the passage?
Option 1 : Tides result mainly from the moon's gravity and the earth's rotation, modified by the sun's pull.
