In what two places do convection currents form when the Sun heats Earth?
Convection currents form in the atmosphere and oceans when the Sun heats the Earth. As the air and water near the Earth's surface warm up, they become less dense and rise, creating a circulation pattern where cooler air or water replaces them.
Why cant convection currents form if they are heated from the top?
Convection currents form when a fluid is heated from the bottom, causing it to rise and create a circulating flow. If a fluid is heated from the top, there is no temperature difference to drive the circulation, preventing convection currents from forming. Heat needs to be applied at the bottom to induce the necessary buoyancy-driven flow for convection currents to occur.
How are currents that form in heated air similar to currents that form in heated water?
Both air and water currents that form due to heating are driven by a combination of density differences and convection. As the air or water is heated, it becomes less dense and rises, causing a flow of cooler, denser fluid to move in to replace it. This sets up a continual circulation pattern as the fluid cools, sinks, gets reheated, and rises again.
What is the relationship between convection currents in the ocean and convection currents in the atmosphere?
Which best explains the relationship between ocean currents and convection currents?(1 point) Responses Convection currents join with the Coriolis effect to create the winds that drive ocean currents. Convection currents join with the Coriolis effect to create the winds that drive ocean currents. Ocean currents rely on warm convection currents to strength the Coriolis effect. Ocean currents rely on warm convection currents to strength the Coriolis effect. Ocean currents create a Coriolis effect that increases convection currents. Ocean currents create a Coriolis effect that increases convection currents. Convection currents use the Coriolis effect to generate ocean currents.
The upward movement of warm air and the downward movement of cool air form what?
The upward movement of warm air and the downward movement of cool air form convection currents. This process is a key factor in driving weather patterns and climate phenomena such as thunderstorms and ocean circulation.
What should the air temperature be for the convection currents to form?
has to be cold
Which diagram correctly indicates why convection currents form in water why water is heated?
which diagram correctly indicates why convection currents form in water when water is heated
How do difference in air density cause convection currents?
It just happens because of the differenciation in the air density which allows the so called convection currents to occur/form. Complex I know but is the closest conclusion.
What property of the air has the most influence on convection currents?
Temperature is the property of air that has the most influence on convection currents. Warm air is less dense than cold air, causing it to rise and create upward convection currents. Conversely, cold air is denser and sinks, leading to downward convection currents.

What form of energy leads to convection currents?
the form of energy would be heat. convection currents are caused by uneven heating of air or fluid. The warmer fluid is more boyant than the cooler fluid, so it floats to the top, and creates a "convection current"

How do glider use convection to stay flying?
Convection allows warmer air to rise because it is less dense than colder air. Because temperatures are greater near the ground (due to the ground's absorption of infrared radiation from the sun), the air at ground level tends to be warmer than the air at higher altitudes. Therefore, the air at ground level rises to form convection currents (currents of rising air), which, when impacting a glider's wings, generates lift, which allows them to remain in the air, or even rise to higher altitudes.
Where does water vapor go when it enters the air?
Water vapor triggers convection currents that can form clouds.
Use the word convection in a sentence?
the earth's convection currents cause continental drift.
What are facts about Convection Currents?
like air
