Sound waves consist of both compression and rarefaction. The compression is caused when something pushes air away, and it bunches up, causing a pressure increase. Rarefaction is the reverse; when you pull away, you create a low pressure area and pull the air with it. However, the overall energy expenditure moves outwards, as each successive volume of air is affected by the one before it, which was affected by the one before that, all the way back to the source.
the photons travel outward from a light source in all directions.
Photons travel outward from a light bulb in all directions
Yes!
there are two forms of energy 1. first is that which is associated with the source.. 2. this is by energy source is not visible or not at all there now .. Energy either travels at its own Or it takes help from the source .... or even one time energy stimulation is enough to propagate that through space energy like light need help from source for generation and survival other travel this way.
A tornado is a violently rotating column of air. Air in and around a tornado moves inward and upward in a spiral pattern. Unlike in a microburst, tornado damage usually follows a discrete path. A microburst is a sudden and intense downdraft within a severe thunderstorm that produces powerful winds. Unlike a tornado the winds in a microburst travel downward and outward and do not rotate.

Outward. Energy is converted in the Sun's core (center), through nuclear fusion, and producing heat; from there, it gradually moves outward.
Outward from the source.

In a low pressure system winds travel in a counterclockwise direction and inward
It could either be the time of travel of echo from reflector to source, or the round-trip from source to reflector and back to source - you'd have to make clear which in the context you are describing.
