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.
It 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.
my qustion was that how was the uneven heating of earth cause convention currents
Yes. Temperature differential causes the molten rock to rise when heated, and when they cool they sink until they heat up again.
No, but shove a lamp up to your penishole will help
its gets crazy
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.
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.
currents caused by the motion of heated molecules
Study Island answer: Wind
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.
mantle
If it is a result of temperature differences, it is called convection.
Magma is propelled to the surface by temperature differences, which cause convection currents. The temperature differences result from radioactive elements within the mantle.
No. Convection currents are the result of a temperature difference between one depth and another in fluid.
differences in temperature and salinity.

Study Island answer: Wind
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.
