What is the source of energy for the life in deep sea ocean trenches where sunlight does not reach?
Answer: Instead of sunlight, vent life relies on hydrogen sulfide – more commonly known as rotten egg gas and toxic to most land-based life. In a process called chemosynthesis, specialized bacteria create energy from the hydrogen sulfide present in the mineral-rich water pouring out of the vents.
How hot is the water as it comes out of a hydrothermal vent?
Hydrothermal fluid temperatures can reach 400°C (750°F) or more, but they do not boil under the extreme pressure of the deep ocean. As they pour out of a vent, the fluids encounter cold, oxygenated seawater, causing another, more rapid series of chemical reactions to occur.
How hot are deep sea vents?
700° Fahrenheit
Why won’t deep sea water boil if its temperature is 400 degrees C?
The boiling point of water varies with atmospheric pressure. At lower pressure or higher altitudes, the boiling point is lower. In the deep oceans, under immense pressure, water remains liquid at temperatures of 750°F (400°C) around hydrothermal vents.
Why doesn’t water boil at the bottom of the ocean?
High pressure does not in any way equal higher temperatures. In fact, water temperature at the bottom of the ocean is generally very cold — way too cold for water to boil. Generally high pressure significantly elevates the temperature at which liquid boils.
What happens when the oceans boil?
Pretty much all living things other than some extremophile bacteria would die as a result. You would probably see temperatures high enough to break down carbonate minerals, releasing CO2, and raising atmospheric pressure and temperature even more.
How can I cook without electricity or gas?

- Rocket Stoves.
- Open Fire.
- Folding Steel Stove.

Will a gas water heater work during a power outage?
Gas water heaters don’t use electricity as a fuel, and many homeowners assume they will work in a power outage. If your gas water heater uses a continuous gas pilot light, it is likely that your gas water heater will continue to function normally in the event of a power outage.
Will a tankless water heater work without electricity?
Tankless water heaters do not work without electricity. Even natural gas and propane-powered tankless water heaters need an electrical supply to function, as they depend on a digital remote or PC board to sense the flow rate of the water. Thankfully, many tankless water heaters use a standard power outlet.
Will gas still work without electricity?
Obviously, your electric range or induction stove top will not work in a blackout, but gas stoves are more complicated, as they use both gas and electricity. In general, most gas appliances will still work, including the water heater, but gas stove burners are typically lit by electric ignition systems.
How long will food keep in fridge without power?
