How do convection currents help form underwater mountains?

The convection currents are the ones that create the force that breaks up and moves the crustal plates on the surface of the planet. By moving the crustal plates, the convection currents contribute to the formation of different types of plate boundaries, including the divergent plate boundaries.

The divergent plate boundaries are the boundaries where two plates are moving away from one another because the convection currents are dictating that kind of movement from bellow them. As they move away from each other, they leave a gap between them, and the convection currents push up a lot of magma towards the surface. The magma cools of very quickly in the water, thus forming rocks constantly, rocks that little by little start to make a big mas, that eventually turns into an underwater mountain, or rather a mid-ocean ridge.

<h2>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 ( $90\º$ ), being the gravity attraction on the masses of water the minimum. This happens in the crescent and wanning phases.
