When the temperature of a fluid or gas is increased then the molecules of which it is composed vibrate more and take up more room. The part nearest the heat source therefore becomes less dense than the parts of the substance further away. The less dense parts are therefore buoyant and float upwards and are replaced by colder parts which sink - this movement is called convection.

∙ 13y agoIt causes convection currents because there is hot air and cold air.The hot air will will rise and the cold air will sink. then the cold ari will rise and the hot air will sink. it all changes.For instance, the hot air after it rises will sink down adn become cold air. The cold air after it sinks, it will become hot air and rise.

∙ 10y agomy qustion was that how was the uneven heating of earth cause convention currents
Wiki User
∙ 14y agoYes. Temperature differential causes the molten rock to rise when heated, and when they cool they sink until they heat up again.

warm air goes up then cold air fills the void warming up then the warm air comes back down to cool and then it repeats over and over

warm air goes up then air follows to get warm then the warm air goes down to cool then it repeats.

What are convection currents in a mantle?
The asthenosphere is the layer of the Earth directly below the brittle lithosphere, made of solid rock with a small percentage of melt, which is under tremendous pressure and temperature conditions. It performs and moves in a ductile fashion (highly viscous) even though it is considered rock, and does not break while under stress, but can move due to convection currents of heat arising from Earth's interior.
What occurs as result of convection currents?
currents caused by the motion of heated molecules
The Sun heats Earth's atmosphere unevenly This causes convection currents to move in large circles in the atmosphere What is the result of convection currents in the atmosphere?
Study Island answer: Wind
Describe the convection currents that occur inside Earth?
Convection currents are the movement of fluid as a result of differential heating or convection. In the case of the Earth, convection currents refer to the motion of molten rock in the mantle as radioactive decay heats up magma, causing it to rise and driving the global scale flow of magma.
Which layer of earth are the convection currents that directly result in tectonic plate motion found?
mantle
What are circulating currents in a fluid called?
If it is a result of temperature differences, it is called convection.
What provides the force that causes magma to the surface?
Magma is propelled to the surface by temperature differences, which cause convection currents. The temperature differences result from radioactive elements within the mantle.
Do convection currents create heat?
No. Convection currents are the result of a temperature difference between one depth and another in fluid.
What are currents that are caused by differences in water density most often the result of?
differences in temperature and salinity.
The type of energy called convection happens as a result of?
Convection currents
What is convection result of?
currents caused by the motion of heated molecules

What things cause ocean currents?
Ocean currents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement- a process known as convection. Convection occurs because the oceanic waters heat up becoming less dense. Winds have the most important influence on the flow of currents, but tides, precipitation, evaporation rates, shape of the ocean floor, and inflow from rivers and adjacent seas are also important.
What provides the force that causes magma to erupt to the surface?
Magma is propelled to the surface by temperature differences, which cause convection currents. The temperature differences result from radioactive elements within the mantle.
