The most common volcanic emission even from dormant volcanoes?
There are several causes of volcanic eruptions. Some of the most common are the buoyancy of the magma, pressure form the gases in the magma, and a new batch of magma entering an already filled chamber.
What affect provided by water aerobics helps make the exercise beneficial?
Buoyancy
Why might molten rock rise and sink beneath the earths surface?
changes in buoyancy due to changes in density differences between the magma and surrounding rock.
How a volcano erupts and forms a volcanic mountain?
It seems like a pretty simple question when you first pose it, so let's look into the answer, shall we. The simplest answer would seem to be that magma, being less dense than the rock surrounding it, tries to float to the surface. If the magma contains water and dissolved gasses, when the magma reaches the surface the water and dissolved gasses will suddenly expand into steam and gas, causing a violent eruption. There are several factors that will trigger a volcanic eruption, but three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber. When rock inside the Earth melts, its mass remains the same, but its volume increases, producing magma that is less dense than the surrounding rock. This lighter magma rises toward the surface because of its buoyancy. When the density of the magma between the zone of its generation and the surface is less than that of the surrounding and overlying rocks, the will magma reach the surface and erupt.
What were the causes of eruption from the volcano in Iceland?
From Scientific American:"When a part of the earth's upper mantle or lower crust melts, magma forms. A volcano is essentially an opening or a vent through which this magma and the dissolved gases it contains are discharged. Although there are several factors triggering a volcanic eruption, three predominate:the buoyancy of the magma,the pressure from the exsolved gases in the magma andthe injection of a new batch of magma into an already filled magma chamber."You can read more about the process, below.
What kind of buoyancy do submarines have when they are resting on the surfce of the ocean?
Positive Buoyancy. When submarine submerges, it initially uses negative buoyancy to submerge, and then levels out to neutral buoyancy.
What does buoyancy help with?
High buoyancy=easy to float
Does freshwater have buoyancy?
Yes, all fluids have buoyancy.
Was buoyancy always called buoyancy?
yes, it is the same.
Could you find a scientific sentence with the word buoyancy?
We are merely testing the buoyancy of several types of ping pong balls.
When was buoyancy found?
The phenomena of buoyancy was first discovered by Archimedes.
How can buoyancy be demonstrated?
buoyancy can be demonstrated if you float something because buoyancy is when something floats for example a boat floating in water
