How does does gas behave at different depths in a magma and how does it influence eruptive style?

At most depths, gas is dissolved in the magma under pressure. When the magma gets close to the surface the gas comes out of solution, forming bubbles which expand rapidly. If enough gas is present in the magma, this expansion results in eruptions that take the form of violent explosions and generate large clouds of ash.

Why arent marine algae found at depths below 200 meters how does this influence life these depths?
because it is too cold
Where Does the squid live?
Squids live in all of the oceans of the world. Different types of squids live at different depths of whichever ocean they inhabit.
Is olivine in the mantle?
There is olivine within the mantle, but it typically occurs at shallower depths (less than 400 km) as at greater depths than this the pressure causes olivine to become unstable forming what are known as high pressure poly-morphs! These have the same chemical composition but a different crystal structure.
What is the major environment factor limiting the numbers of autotrophs at great depths in the ocean?
The major environmental factor limiting the numbers of autotrophs at great depths in the ocean is the amount of light reaching those depths
Does light affects cellular respiration in algae?
Yes, actually. Algae at different depths below sea level have adapted over time to use the available light for cell respiration.

Where do fish breed in the sea?
Different species breed in different areas and at different depths.
Why is it necessary to be able to focus a specimen at different depths on the microscope?
because the subject may have different charactreistics at different depths
How does a fish swim to different depths?
with the lateral fins
What would i find on a contor map?
different heights and depths
How do oceanographers measure the different densities out in the open ocean?
By Bringing up samples at different depths.
What is bit depth?
There are a number of different depths for a number of different bits. The depth needed depends on the project.
What is water temperature at different depths?
hot because when its cold it turn hot
Is soil different at different depths below the surface?
Yes. That is so because of the: color materials (minerals) and organisms.
What is the job outlook for an oceanographer?
going on a dive to collect different samples of ocean water at different depths
How does inflating and deflating help a fish?
It helps so the fish can stay at different depths.....
How deep is the inky depth?
There is no exact depth to the inky deep water. This is because different oceans and seas have different depths.
