When the sun heats the ocean's surface, the water temperature increases, causing the water to expand. This expansion leads to a decrease in water density since warmer water is less dense than cooler water. As a result, the warmer, less dense water tends to rise, while cooler, denser water sinks, creating convection currents in the ocean.
The density decreases.
Earth Plates
When an object heats up, its density typically decreases. This is because as the object's temperature increases, its particles gain energy and move more quickly, causing the object to expand. As a result, the same amount of mass now occupies a larger volume, leading to a decrease in density.
Water (the oceans).
Water is the only thing.
The sun and the earth. The earth has fire/heat/magma inside it that heats up the earth and lakes and oceans
What do you think happens when some air heats up and other air is cool?
it heats up
Air loses density when it heats up because the air molecules become more energetic and spread out, resulting in a decrease in density. Conversely, air becomes more dense when it cools down because the molecules lose energy and come closer together.
Energy from the sun heats up the Earth's surface, oceans, and atmosphere. This heat drives weather patterns, ocean currents, and the water cycle on our planet.
