Why does Mount Etna emit smoke rings?
Because vents in the volcano are so thin compared to over volcanoes that when ever gas escapes it is forced up through these vents into ring-like shapes. It's also to do with the fact that the vents are very round. That's about all I can say, soz. The size of the rings though are around the size of a football pitch because that is around the same size as the vents. I don't know how these vents are considered small it's just in comparison to others :P
Types of volcanic vents?
Magma or lava vents and gas vents. Also fumarole.
Did Krakatoa's eruption have vents?
Yes. It probably did. Mostvolcanoes have vents. They let more lava escape.
What are the vents in a volcano?
Vents in the volcano are passage ways for the magma, steam, and heat to escape the earth.
How does magma inside a volcano become a lava flow outside?
The magma gushes out and then it flows every where. The volcano has vents that let air come out. When the vents open steam/ smoke comes out of those vents.
What is difference between natural and forced convection?
Natural Convection occurs when a warmer less dense fluid is pushed away by a cooler denser fluid. Forced Convection occurs when an outside force pushes a fluid, such as water of air, to make it move and transfer heat. A fan is a perfect example. Im pretty sure air, and heat vents are examples too. An air conditioner is definitely an example.

Is heating vents placed on the floor at home convection?
yes
In force-air heating systems where are warm-air vents usually located?
Near the floor. This allows natural convection currents to mix the warm air as it rises to the ceiling.
What happens at a mid ocean ridge?
The techtonic plates are pulling away from each other. Magma is forced twards the sea floor via convection currents. This results in "hot vents" where an entire ecosystem is based on chemosynthetic bacteria.
How do you take off the heat vents in a home?
Forced air vents set flush in the floor? They generally just lift straight out.
Where are warm-air vents usually located in a forced-air heating system?
Near The Floor
What are natural vents that discharge steam or water from earth?
A geyser is a natural vent that discharges steam or water from Earth.
How does a forced air heating system work?
A forced air heating system uses a furnace to heat air, which is then distributed throughout the building via ductwork and vents.
Why are there vents in compost bins?
Compost naturally emits gases as it decomposes. These vents are to prevent a build up these gases particularly methane(natural gas) as it is highly flammable.
Is sulfur manmade?
No. Sulfur is a natural element. It even occurs naturally as a native element near volcanic vents.
