Question

how do you explain convection currents using the particle model. ??​

Answer 1

$\huge\underline{\overline{\mid{\bold{\red{Answer ♡}}\mid}}}$

✎ Using the particle theory, explain how convection currents work. As particles warm up (gain energy), they move farther apart. Each section of the warmed material is left with fewer particles than when it was cold, so each section is a bit lighter. In other words, the material becomes less dense

Answer 2

$\huge\underline\mathtt{Answer}$

Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.
