The arrows in convection represent the direction of the flow of fluids, such as air or water, as they transfer heat energy from one location to another through the movement of particles. In convection, warmer fluids rise while cooler fluids sink, creating a circular motion that aids in distributing heat evenly in a space.
Forces can be shown in a diagram using arrows. The length and direction of the arrows represent the magnitude and direction of the force, respectively. You can label the arrows with the type of force and its value if known.
In one dimension, the length of the arrows represents the magnitude or size of the vectors. Longer arrows indicate larger magnitudes, while shorter arrows indicate smaller magnitudes. The direction of the arrows indicates the direction of the vectors.
In chemical formulas, the arrows represent the way of the reaction. Two opposing arrows mean that the reaction will go in both directions, until its specific equilibrum is reached.
You can use arrows to show the direction of a force in a diagram. Arrows pointing in the direction the force is acting help to visually represent the force's impact.
The double-headed arrows on polarizers and analyzers represent the direction of polarization that they allow to pass through their material. It indicates that light with polarization parallel to the arrow direction can pass through, while light with perpendicular polarization is blocked.
Scientists believe that forces in the Earth's mantle move the Earth's crustal plates due to convection currents. The arrows in the diagram typically represent the direction and movement of these convection currents, which drive the motion of the tectonic plates. This movement is responsible for phenomena such as earthquakes, volcanic activity, and the shifting of continents over geologic time scales.
The arrows represent the flow of energy.
The arrows in the mantle represent the movement of material within the Earth's mantle due to convection currents. These currents are driven by heat from the Earth's core, causing material to rise, cool, and sink in a continuous cycle that helps drive plate tectonics.
The arrows shown in the asthenosphere represent the inferred slow circulation of the plastic mantle by a process called mantle convection. This process involves the movement of heat from the Earth's core towards the surface, creating a pattern of circulation that drives plate tectonics and other geologic phenomena.
Vectors
The length of the arrows could represent either the magnitude or the direction of the vectors. If the length represents magnitude, longer arrows would represent larger magnitudes of the vectors. If the length represents direction, the arrows would be all the same length, but pointing in different directions to represent different vectors.
The 13 arrows represent the original 13 colonies and the willingness of the country to fight when it is necessary.
The 13 arrows on the great seal symbolize the 13 colonies and how they were forged out of war
Cupid is a Roman god, and his mother is Venus: the arrows represent being "struck" by love.
How energy moves from organism to organism.

This also applies to a food chain - The arrows in a food web represent the flow of energy through the web, further along the arrows/web means that less energy is moving along. The energy flows through arrow to the next consumer, the energy moving through the arrows have less and less energy as the web moves on. To put it in (much) simpler terms, the thing its pointing to eats the other thing.
