primary- PV valves; secondary - PV breaker
Yes, Mt. Erebus does have secondary vents. There are many of them, and they are located close to its inner crater.
Lolo
fumaroles
hydrogen sulfide
The main vent is called, variously, the Primary or Fundamental. Lesser vents are called secondary or lesser. The science of volcano and more recently its co-science of geothermal energy study is Vulcanology. _________________________________________________________________ the main vent is where the volcanic ash and lava escape.
the water most likely is condensate from a clogged condensate drain if you had a secondary drain, you would see water drip from the secondary likely you have no secondary, and you are getting water out the vents if you have some of the a/c in the attic you better get the clog fixed right away, or water may seep through the ceilings note the more humid it is, the more condensation is created--hence, the correlation of your problem with rain
Magma or lava vents and gas vents. Also fumarole.
The Sun is the primary source of all energy in nearly all food chains. However, some deep-sea ecosystems utilize heat from underwater thermal vents as their primary energy sources since sunlight is virtually nonexistent.
Return air vents.........
With either gable vents, soffit vents or ridge vents. The more the better
IF BLOWER MOTER IS RUNNING CHECK FOR PLUGGED: FILTER BLOWER WHEEL OR MOST LIKELY (IF A 90+ FURNACE) THE SECONDARY HEAT EXCHANGER lc
Chemotrophs are also known as bacteria or archaea that live in hostile environments such as deep sea vents and they are the primary producers in these ecosystems only! Hope this helps! :) xxx
