Question

When are tides lowest? What causes these tides to be lowest?

Answer 1

Neap tides, which are the lowest tides, occur when the Sun and Moon's gravitational forces are at right angles to each other, typically during the first and third quarter moon phases.

Step-by-step explanation:

The lowest tides, known as neap tides, occur approximately twice a month when the Sun is at a 90° angle to the Earth-Moon alignment. During these periods, the gravitational forces of the Sun and the Moon act at right angles to each other, which reduces the overall tidal effect. Neap tides happen during the first and third quarters of the Moon’s phase, also referred to as the half-moon. Conversely, the highest tides, called spring tides, happen when the Earth, the Moon, and the Sun are aligned, typically during a new or full moon when their gravitational forces combine to create stronger tides.

Answer 2

Tides are lowest when:

Tides are lowest when the earth, sun and moon come’s in a right angle. It occurs when the greatest pint in the wave or can called the crest arrives at the coast, the coast can feel the high tide, but when the smallest point i.e. trough arrives at the coast feels the low tide. The tidal force present makes the earth also the water to swell out of side which is often nearer to moon and the side farthest to that of moon, when no swelling can be seen low tides occurs.
