Question

Which best describes how fluids change as they travel through different portions of the convection currents? They change to solids at the outer portion of the convection currents. They change to solids at the inner portion of the convection currents. They become more dense at the outer portion of the convection currents. They become more dense at the inner portion of the convection currents

Answer 1

Answer:

Fluids become more dense at the inner portion of the convection currents

Explanation:

Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air.

Convection currents form because when a fluid is heated, it expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, the cooler fluid is pulled down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid. This cycle continues and establishes a circular current that stops only when heat is evenly distributed throughout the fluid.
