Eruptions in the deep ocean differ from eruptions on land for several reasons. The deep ocean eruptions are often tmes and depending on cause as well as location from basaltic magma. This type of magma is not known for its explosivity. The magma is the type that build the hawaiian volcanoes and more or less when erupting flows (Although it is capable of explosive eruptions). The other major factor is for an explosive eruption to be generated the magma must be very viscous to allow the build up of gas bubbles. The second half and what actually causes the explosive eruption is the explosive release of this gas. When an eruption occurs in the deep ocean it is not explosive due to the fact that the gas cannot decompress from the magma explosively due to the extreme pressures exerted by the water at such depth. Even if it were the right type of volcano that could generate explosive eruptions with the pressure it would be unable to do such a thing.

Why does a hurricane get calmer over land?
Friction with the land helps to lower the wind speed.
What is the most common cause of tsunamis?
Tsunami are waves caused by sudden movement of the ocean due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean.
What geologic land for that occur at a convergent boundary?
At a convergent boundary, geologic features that can form include mountain ranges, deep ocean trenches, and volcanic arcs. Subduction zones are also common at convergent boundaries, where one tectonic plate is forced beneath another. These processes can lead to earthquakes, volcanic eruptions, and the formation of new rock formations.
How are new land formed?
New land can be formed through volcanic eruptions, where lava cools and solidifies on the earth's surface, or through the deposition of sediment carried by rivers, glaciers, or ocean currents. Land can also be created through processes like tectonic plate movements, which can lead to the uplifting of land or the formation of new landmasses.
What is a sea wave caused by earthquakes and volcanic eruptions?
A sea wave caused by earthquakes and volcanic eruptions is known as a tsunami. These powerful waves are generated when there is a sudden displacement of water, typically due to the movement of tectonic plates during an earthquake or the collapse of land following a volcanic eruption. Tsunamis can travel across entire ocean basins at high speeds and can cause devastating impacts when they reach coastal areas. Unlike regular ocean waves, tsunamis have a much longer wavelength and can inundate large areas of land.
What are some characteristics of a bay?
A bay is a body of water partially enclosed by land. They often have calmer waters compared to the open ocean due to protection from surrounding land formations. Bays can vary in size and shape, with some being very shallow and others deep enough to accommodate ships.
The land under the ocean is divided into the deep ocean basin and the margin?
it was big and ugly
Why is the ocean so deep?
The ocean is deep because of the Earth's crust, which is thinner under the ocean than on land. This allows more space for water to fill, creating the deep ocean basins. Additionally, the movement of tectonic plates can also create deep trenches in the ocean floor.
Why do you think that mining on land is less costly than mining in the deep ocean is?
Mining on land is less costly than mining in the deep ocean because it takes more equipment to go down to the bottom of the ocean, and all of that equipment costs more money than what they use on land.
Why does a hurricane get calmer over land?
Friction with the land helps to lower the wind speed.
Where is the Ross Sea?
The Ross Sea is a deep bay of the Southern Ocean in Antarctica between Victoria Land and Marie Byrd Land.
What are the two types of ocean currents?
deep currents streamlike movement of water that flow very slowly along the ocean floor. surface current can influence the climate of land are they flow past.
Which ocean is green land located in?
Most of Greenland is in the Arctic Ocean. Greenland is located at the northern extremities of the Atlantic Ocean extending northwards deep into the waters of the Arctic Ocean. Source Oceandot.com
Do most living things live deep in the earth?
No. Most living things live in the ocean or on the land.
What is a small area of ocean that is covered by land called?
The usual term for a coral island is an atoll. Some exist in otherwise deep ocean waters.
What make trenches in the ocean?
Deep ocean trenches can be formed by undersea earthquakes, land-slides, but also by the movement along the edges of tectonic plates.
How a tsunami wave forms in the deep part of the ocean and what happens as it approaches land?
I think their is an earthquake in the ocean and it roles up into a huge wave and when it approches land it is as biggest as it can get and boom it hits the land
