Because the water molecules which are far inside the liquid experience an outward force, and has no maximum potential energy.
It begins to get warmer from the sun's radiation.
Probably because it is warmer and hence lighter.
In a convection current, air molecules near a heat source become energized and rise due to lower density. As these molecules cool, they become denser and sink back down, creating a circular motion of air flow known as a convection current.
A warmer world is least likely to result in lower energy consumption. Increased temperatures may lead to more frequent use of air conditioning, causing energy usage to potentially rise.
Warmer Air does this.
Warmer air rises because it is less dense than cooler air. As air is heated, its molecules move faster and spread out, causing the air to become lighter and rise above the cooler, denser air. This process is known as convection.
No. Currents in the air and oceans are caused by the heat from the sun.
Warmer
Molecules in cold substances move more slowly compared to molecules in warmer substances because lower temperatures reduce the energy of the molecules, causing them to move less and at a slower pace.
When molecules are heated, they increase in kinetic energy and tend to rise due to decreased density. This is because as a substance is heated, its molecules spread out and become less dense, causing them to rise in a fluid medium such as air or water.
move faster.
move faster.
Cold air rises because it is denser than warm air. When air is cold, its molecules are closer together, making it heavier and causing it to sink. As a result, the warmer, less dense air around it pushes the cold air upward, causing it to rise.
Buoyant air will rise until it reaches warmer air that is the same density as itself.

Probably because it is warmer and hence lighter.
