What is a convection current?
Convection currents are vertical movements of fluids driven by heat. Hot fluids rise because they are less dense than cold fluids which sink. The best example would be soup boiling - stuff in the soup comes to the surface over the flame and sinks back towards the edges of the pot.
Current caused by the expansion of a liquid, solid, or gas as its temperature rises. The expanded material, being less dense, rises, while colder, denser material sinks. Material of neutral buoyancy moves laterally. Convection currents arise in the atmosphere above warm land masses or seas, giving rise to sea breezes and land breezes, respectively. In some heating systems, convection currents are used to carry hot water upwards in pipes. Convection currents in the hot, solid rock of the Earth's mantle help to drive the movement of the rigid plates making up the Earth's surface.
Yes. Convection is a type of energy and a convection current is, well, the phrase for its currents. So yeah, convection and convection current are the same.
Convection current is a stream of fluid propelled by thermal convection. Convection is mostly around gas and liquid
there is no synonyms or antonyms for convection current
Convection current Convection current
The Gulf Stream is an example of convection current.
no an example of a convection current is a blow drier
A convection current is not a technological term; it is a term used in Science for talking about air current. A convection current is the cycle of hot air going up, and cold air going down.
By remembering the process of convection and convection current rainfall we can relate both. Land breeze and sea breeze are due to convection current and humidity also occur there due to this.
Warmer material in a convection current rises upwards.
It turns because of density changing. You see, the convection current goes up and then it doesn't have anywhere else to turn do then the density cools too and then the convection current goes down.
a convection current transfers heat within a fluid.
What do you think will happen to the convection current in the mantle if the interior of earth eventually cools down?
The convection current will stop.
probably the convection currents in the troposphere that connects the troposhere and the stratosphere.
cooler air sinks,pushing warmer air upwards. the result is a circulating current of air called convection current
For an example if the question was what is a convection current you would say: I think a convection current is. And then you would tell your answer.
It turns because a convection cell is one big loop of a convection current
Waves is the part of convection current. This is the mantle and is related to plate motions.
The convection current occurs in the asthenosphere.
Convection current ------> moves tectonic plate -----> plate movement causes quake along boundary.
a convection current occurs when a potato picked by a farmer falls off the wagon and is eaten by a donkey ps: your welcome
Dig a hole to the mantle and ask it.
Actually, there are many ways for a convection current to form. So, if you asked this question, here is one way: A convection current forms when Hot air and Cold air form a cycle and mix. . . That's one way! Toodles Byee
convection current is what causes tectonic plates to move.
yes boiling water is an examole of convection........... or is it????????? :) :( hahahahahahahahahahahahahahhahahaahahahhahahahahahahahahahaha!!!!!!!!!!!!
A convection current is when hot air rises, and cool air fall, creating convection. ~Britney, 7th
The convection is a current caused by warmer liquid rising and cooler liquid sinking.
Convection currents in the mantle drag the plates like a conveyor belt.
convection currents are the force behind plate movement.
Convection causes the Global weather to change in the tropics. Because of the expansion of the heat during the process of convection, it causes a convection current.
The fluid nearest to the heat source warms and expands, becoming less dense. It rises and cools, becoming denser again, so it sinks and the cycle is repeated.
a convection current is the flow that transfers heat withen a fulid.
the convection currents of lava underneath the earth's crust move the earth's crust. convection current is magma being heated, and is pushed to the crust, it then cools and sinks to the bottom, where it is to be heated again.
Because the cold goes down and pushes the heat up make a convection current
In geology, the Earth's convection currents are caused by the motion of heat from the Earth's interior.
the convection currents will stop
a convection current
Solids are rigid.
Convection current is the flow of hot fluid in a circular pattern. A convection current is a form of transfer of energy. It occurs mainly in liquids, but it can also occur in gases. In a convection current, the particles with greater energy (the particles that are hotter) rise because they become less dense. As they rise, particles with less energy (cooler particles) rush in to replace the particles that rose as they are more… Read More
warmer material will move upward were it cools then fall back to the bottom so it can start the cycle (convection current) once again
He won't complete many push-ups on that hot deck due to a little thing I like to call "the convection current effect".
Yes, because otherwise, the plates, moved by the convection currents, won't move at all.
As the flask is closed air tight, no convection current is possible.
The current is reversed from the morning's cycle
temperature differences in the mantle
The ocean ridges push the old crust into a convergent boundary where it goes into a mantle convection current. The crust then melts in the convection current and is pushed out of the ocean ridge to restart the process again.
