Convection currents are currents caused by the expansion of a liquid, solid, or gas as its temperature increases.while colder, denser material sinks.. 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 .
What else can I help you with?
What causes a convection current?
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!ToodlesByee
What term describes the way material moves during a mass wasting event?
The term that describes the way material moves during a mass wasting event is "flow." This can include different types of flow like avalanches, mudflows, debris flows, and rockfalls. The movement can range from slow and gradual to fast and sudden, depending on factors like slope angle, material composition, and triggering events.
Do convection currents always affect the same way?
No, convection currents can vary in strength and direction depending on factors such as temperature gradients, fluid properties, and boundary conditions. In general, convection currents result from the movement of fluids due to differences in temperature, but the specific behavior can be influenced by a variety of factors.
Is longshore drift the cause or the effect of a longshore?
Longshore drift is the effect of longshore current because the water moves a certain way and causes the sand to take shape.
In which layer of the sun is energy transferred between atoms?
In the convection Zone!
What describes the way a convection moves?
Convection is a process where heat is transferred through the movement of a fluid (such as air or water). As the fluid is heated, it becomes less dense and rises, while cooler, denser fluid sinks. This creates a circulating flow pattern known as a convection current.
How can mantle flow because its made of hot liquid magma?
Magma in the mantle moves in a current called a convection current. A convection current is a circular flow of a substance in which a hot substance rises, cools, sinks, gets hot again, and repeats. In this way, magma in the mantle flows in currents of more hot or more cool magma.
What motion best describes the way a wave moves?
a sweeping motion
What is eddying?
An example of eddying in a river is when the current moves in a circular way.
In Which way can heat be transferred by a convection current?
By water or any other fluid that may work. =).....I think
What way does air move in a convection current?
In a convection current, air molecules near a heat source become energized and rise due to lower density. As these molecules cool, they become denser and sink back down, creating a circular motion of air flow known as a convection current.
Why are currents changing direction?
Alternating current is generated by a rotating generator which moves in such a way as to produce that kind of current.
Explain how thermal energy moves in gases compared to the way it moves in soilds?
In gases mainly by convection, that is by bulk movement of molecules of the gas. In solids by conduction, that is by contact between atoms of the material.
Which way round does convectional current flow?
A convection current flows in a circular pattern, with warmer material rising and cooler material sinking (due to density differences). It should not be used with conveNtional current in electricty.
What is the method by which heat is transferred into in a fluid liquid or gas?
Transfer of heat in nature occurs through three ways: conduction, convection and radiation. Conduction takes place in solids. Convection in liquids and gases. Radiation takes place in all three media as well as in vaccum.
How does the earth magnetism work?
Our Earth's outer core consists of a liquid iron, which is highly conductive. As this liquid moves via convection (the same way water boiling in a pot moves via convection), electrical fields are generated, which then create a magnetic field -- a farily simple electromagnetic. The EXACT mechanics of this are difficult to work out, but has been done.
What are characteristics of convection?
Convection is the transfer of heat through the movement of fluids or gases. It occurs due to the difference in density of the fluid at different temperatures, causing it to rise and fall, creating a convection current. Convection is an efficient way to transfer heat because it can distribute temperature changes throughout a fluid.
