Water can catch fire but why is there still volcanic eruption in the ocean?

Listening to volcanoes in the ocean is a bit wrong, but why do volcanoes form and erupt under the sea? The answer surprised you!

The island with white sand blue sea like Hawaii is an ideal destination for those who love travel. But hidden deep in the sea there are volcanoes. So why can volcanoes form underwater?

rarer than terrestrial volcanoes but are the most positive and powerful. According to statistics, nearly 75% of the annual magma on Earth comes from undersea volcanoes.

Undersea volcanoes are rarer than terrestrial volcanoes.

It is difficult for geologists to grasp the activity and condition of these volcanoes because they are hidden thousands of meters deep in the ocean.

They must study the debris or rocks after the volcano erupted. This way helps them to know how the volcanic heat and chemicals in the sea volcano have worked.

Volcanic eruptions in the ocean.

According to geologists, the principle of marine or terrestrial volcanic formation is the same. They are formed when tectonic plates (ocean or continental plates) collide or split apart.

The impact of tectonic plates is governed by various factors such as the rotation of the Earth, tidal forces, the gravity of the Earth, the Moon and the Sun.

When focused together, the heavier tectonic plate will slide under the lighter plate, forming a channel between the two tectonic plates. The rocks stuck in this trench gradually melt, enabling lava to rise to form hot spots.

Lava accumulated to the crater and finally erupted in the water.

The second case is when two tectonic plates are separated by water pressure and convection flow. The separation of tectonic plates inadvertently creates space between them, making the lava below have a chance to move to these cracks.

Over time, lava accumulates to the crater and eventually erupts in the water. However, because the crater is surrounded by water and water pressure, right after eruption, lava will be frozen, also known as lava pillow or magma stone .

Over millions of years, these magmatic layers can form volcanic "islands".

This is a special feature of volcanoes in the ocean. Gradually, the layers of magmatic rock solidly overlapped and formed a mountain. Over millions of years, these magmatic layers can form volcanic "islands".

Large islands like Hawaii island are located in the Pacific Ocean formed by hot spots and magmatic rocks. They had to undergo strong volcanic activity to become islands like today.
