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.

Container used to collect water samples from different depths?
A Niskin bottle is commonly used to collect water samples from different depths in bodies of water. It is a cylindrical, free-flowing tube that can be triggered to close at specific depths, capturing the water sample within the container for analysis.
What is the relation between alternate depths in rectangular open channels?
In rectangular open channels, alternate depths refer to two different water depths that the flow can take within the channel. These depths are symmetrically positioned about the channel bottom and are a result of the conservation of energy in the flow. The alternate depths occur when the flow transitions between supercritical and subcritical flow conditions within the channel.
When does brittle deformation occur?
Brittle deformation occurs when rocks break or fracture due to stress rather than bending or folding. It typically occurs at shallower depths in the Earth's crust where temperatures and pressures are lower, causing rocks to behave in a more brittle manner.
Is the salinity uniform throughout?
No, salinity is not uniform throughout the ocean. It can vary due to factors such as evaporation, precipitation, input of freshwater from rivers, and mixing of water masses. Salinity levels can be different in different regions and at different depths within the ocean.
Why arent marine algae found at depths below 200 meters how does this influence life these depths?
Marine algae require sunlight for photosynthesis, which is the process that provides them with energy. Light penetration decreases with depth, leading to insufficient light for photosynthesis beyond 200 meters. This absence of marine algae at depths below 200 meters can limit the availability of food and oxygen for other marine organisms, impacting the overall biodiversity and food web dynamics in these deep-sea ecosystems.
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?
Focusing at different depths allows you to visualize different layers within a specimen, providing a 3D view. This can help to identify specific structures or features within the specimen that may be located at different depths. Focusing at different depths is crucial for obtaining clear and detailed images of the entire specimen.
How does a fish swim to different depths?
with the lateral fins
Why do not all density currents reach the same depths?
Density currents can have different depths due to variations in the initial density contrast, the amount of mixing with surrounding fluids, and differences in temperature and salinity gradients. These factors can influence the speed and penetration depth of the current as it moves through a fluid with varying densities.
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.
Container used to collect water samples from different depths?
A Niskin bottle is commonly used to collect water samples from different depths in bodies of water. It is a cylindrical, free-flowing tube that can be triggered to close at specific depths, capturing the water sample within the container for analysis.
Impossible to observe object clearly at different depths at the same time?
This is due to the principle of accommodation in the human eye, where the lens adjusts to focus on objects at different distances. Therefore, the eye cannot simultaneously focus on objects 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
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.....
