Answer

Brief Explanations:

  1. The passage focuses on how the gravitational force between the Moon and Earth affects the tides. The text details how the ocean water moves in response to the Moon's position relative to Earth, causing high and low tides.
  2. The central idea is stated. The first - sentence sets up the concept of something off - planet (the Moon) causing daily environmental changes, and subsequent sentences explain how this occurs with the tides.
  3. Details such as "the oceans are not fixed in place, they move in predictable directions as the moon changes its position relative to the Earth", "water to bunch up during one part of the day (high tide)" and "flatten out during other times (low tide)" support the central idea.

Answer:

  1. The gravitational force between the Moon and Earth causes the tides, with ocean water moving in response to the Moon's position relative to Earth.
  2. Stated. The first sentence sets up the concept and subsequent sentences explain it.
  3. The oceans' non - fixed nature, water bunching up for high tide and flattening out for low tide.
