what are the types of tides ? define each of them
Answers
There are two main tides that are higher or lower than average. They occur twice monthly and are called neap and spring tides.
Neap tides
When there is a low tide, the Moon faces the Earth at a right angle to the Sun so the gravitational force of the Moon and Sun work against each other. These tides are referred to as neap tides; a low tide or one that is lower than average. A neap tide happens between two spring tides and occurs twice a month when the first and last quarter Moon appears.
Spring tides
When there is a high tide, the Sun, Moon and Earth are in alignment and the gravitational force is strong. These tides are known as spring tides and occur twice a month. In this case the Moon can appear in between the Earth and Sun resulting in a solar eclipse, or at the furthest point away from the Sun resulting in a full Moon. When in alignment, the Moon and Sun combine in gravitational forces to bring the highest and lowest tides of the month.
Answer:
High tide and low tide. Average level of water
We will use two classifications to define the tide types. The first of them is the value awarded to the height of the tide and is the one reflected in the tide tables. The second is the lunar phase and is directly related to the average activity of fish in the solunar charts.
According to the height of the tide
High tide: when the sea water reaches its greatest height within the tide cycle. They are shown in blue on the tide tables.
Low tide: when the sea water reaches its lowest height within the tide cycle. They are shown in red on the tide tables.
Normally there are two high tides and two low tides for every lunar day as, at the same time as the Moon lifts the water over the Earth on the side facing it, it also separates the Earth from the water on the opposite side.
The result is that the water lifts over the terrestrial surface on the two diametrically opposite sides of the planet.
