How does convection current works?
convection currents work when heated water cools then goes to the bottom then heats back up
What are convection currents responsible for?
Convection currents are responsible for the movement of heat (and mass) within a fluid system. Heat wants to go from where it is to where it isn't. When atoms and or molecules of a fluid (a gas or liquid, for example) are hotter then their companion particles, they are less dense and rise in the fluid. Cooler, more dense groups of atoms or molecules take their place. Convection currents are thus set up, and heat travels "around" the system via those currents. A link to the Wikipedia article on convection is provided.
What are some effects convection currents have on the world?
Convection currents inside the Earth happens. The part where the convection currents go up, it brings up materials from the mantle like rocks. This forms new crust. When the convection currents go down, it brings down some older, colder oceanic crust to the mantle, destroying it. In conclusion, the crust is formed and destroyed when convection currents inside the Earth happen.
How does convection currenctions work inside the earth?
Convection currents happen in the mantle and cause tectonic plates to drift. The earth is made up of the iron and nickel core, then the mantle then the crust. And the earths surface is made up of tectonic plates. These plates move due to convection currents.
What do convection currents look like?
Convectional currents look like a cycle. For example, if you have a radiator in a room, it will heat the air around it. That hot air will rise up and then cold air will replace it. This goes round and round in a cycle. This cycle of warm air rising and cool air falling is called convectional current. This current happens in only liquid and gas.
What is the role of gravity in creating convection currents?
Gravity causes the convection currents. Without gravity, convection would have been completely backwards. Gravity pushes the cold air down and stops the warm air going up.
How are currents that form in heated air similar to currents that form in heated water?
Currents that form in heated air are similar to currents that form in warm water because heated air goes up and cold air goes down creating convection currents.
How are crustal plates moved?
It is causes by Bobby Chen jumping up and down
Why convection currents can be set up in liquids and gases but not in solids?
Matter doesn't move easily in solids.
What are convection current and how do they happen?
Convection currents are the movement of any substance from one area to another. A typical example would be air currents. The sun heats the ground, causing the air above it to heat up and rise. Cold air is drawn into the area to replace the warm air (which is what we feel as wind)
How does convection current works?
convection currents work when heated water cools then goes to the bottom then heats back up
Why it is more effective for heaters to be place close to the floor and coolers to be place closer to the ceiling?
hot air raises, cool air will drop. This helps set up convection currents to disperse the heat/cool throughout the room.
What happeneds when convection lift air high up in the atmosphere?
How convection cyle are set-up near the earh? Warmed air sinks, creating a high-pressure area as it falls.
How do convection currents in the mantle effect lithosphere movement?
Convection currents rotate in the Lithosphere, which causes the surface of the Earth to move.
Do convection currents have to do with tornadoes?
When convection occurs with very warm, moist air, thunderstorms can form. As warm, moist air flows up in a convection cell it cools and the moisture in it condenses. The condensation releases energy that powers the thunderstorm. Given the right conditions and the right interaction of wind currents, that thunderstorm may go on to produce a tornado.
What is it called when heat moves through a liquid?
You are probably thinking of convection, which is transfer of heat by currents set up by variations in density of the liquid.
