Answer:

B.in a controlled way

Explanation:

Fuels are all chemicals that, when reacting with oxygen (O2), undergo a chemical phenomenon called combustion, releasing a certain amount of energy in the form of heat. This energy must be released in a controlled manner, avoiding accidents and waste.

Every burning of a fuel is an exothermic (heat-releasing) chemical reaction, but the products that originate always vary according to the fuel used. Fuels can generally come from a variety of sources, such as animal, vegetable, water hydrolysis or waste. Regardless of origin, for fuel to be useful, energy must be released in a controlled manner.

How do ocean currents influence the climate of a place?
sveticcg [70]

<u>ANSWER:</u>

The correct option is A: They transport heat over long distances affecting the wind that blows over the land.

<u>EXPLANATION:</u>

  • Ocean currents carry cool or warm water or currents over long distances thereby affecting the wind that blows over the place bringing about a change in the climate.
  • When the ocean currents carry cool air, the warm wind gets displaced by the cool air and therefore the climate of the place becomes cold.
