Answer:
B. convection because warm air rises and cool air sinks.
Explanation:
The processes that enables birds to fly to higher altitudes without flapping their winds while riding air thermals is called convection.
Convection is one of the forms of heat transfer usually found in gases and liquids.
- In convection density differences due to temperature changes causes the circulation.
- Warm air is less dense and it is hotter.
- It rises up from the surface where it is warmed
- Cold air sinks to replace the warm air. Cold air form when the air loses its energy to the surrounding.
- By virtue of this, birds are able to take advantage of it for their flight.
Actual Resources: are those which have been surveyed, their quantity and quality determined and are being used in present times.
Potential Resources: <span>They can exist in a region and can be used in the future.</span>
It is the first option bc if it absorbed heat it it will pressurize and could explode.
