Answer: They are extra-high tides and extra-low tides.</h2>
Explanation:
Tides are periodic movements of the great masses of water on our planet as part of the gravitational attraction exerted by the moon and the sun on Earth.
In this sense, there are two very special cases: The Spring and Neap tides.
<u>Spring tides </u>
Occur when there is a full moon or new moon, which makes the <u>tides higher.</u> During these lunar phases, the Moon, the Earth and the Sun are aligned and the gravitational attraction power is greater.
<u>Neap tides </u>
Occur when the moon, the earth and the sun form a right angle (
), being the gravity attraction on the masses of water the minimum. This happens in the crescent and wanning phases.
Then it is moving towards earth

Smallpox is one of two infectious diseases to have been eradicated.
