(4) A. in a straight line

C. at an acute angle measuring 23 degrees

1. Earth’s tides are affected by the gravitational pull of the Sun and the Moon, but mainly the Moon because the Moon is closer to the earth.

In spite of high pull of the Sun, the distance of moon from earth results in increased effect of moon gravitational pull than Sun.

2. Each day, each coastal region on Earth experiences two high tides and two low tides in every 24 hours time period.

The daily tides has been resulted at the coast with the moon revolution around the earth's rotation.

3. This is because the gravitational attraction of the Moon creates tidal bulges on two opposite sides of the planet.

The effect of the moon gravitational force results in the bulging or the pulling force to the sea, resulting in the diurnal tides.

4. Two spring tides occur monthly, when the Moon is in its new and full phases. During these phases, the Moon and Sun are oriented at a right angle measuring 90 degrees which gravitation pulls the water on Earth in the same direction, creating a large tidal range.
