What is downward displacement of air?
Downward displacement of air refers to the movement of air particles in a downward direction, usually caused by the sinking motion of air masses or the influence of gravity. This can result in increased air pressure at the surface and can be associated with stable weather conditions.
What is happening to create convection currents in the mantle?
in the asthenosphere, which is in the lower part of the mantle, magma churns in a convection current which is like a cycle. Tectonic plates sit above this movement in the lithosphere. This is what causes continents to move little by little. Hot magma rises and at the lithosphere, it cools and falls because it is now denser. This is like a circular movement, or convection current.
What causes the global convection current between the equator and the polls?
The difference in temperatures between the Equator and the north and south poles, plus the rotation of the earth, causes the air currents.

During convection hot material do what?
During convection, hot material rises due to its lower density, creating a current that transfers heat from the hot material to cooler material. This process then causes the cooler material to sink and cycle back towards the heat source, creating a continuous convection current.
What is the nae of the prossoe of warm air rising asnd cool air sinking?
The process you are referring to is called convection. Warm air rises because it is less dense than cool air, which causes it to displace the cooler, denser air and sink. This cycle creates a convection current that plays a key role in atmospheric circulation and weather patterns.
The downward part of a convection current causes a sinking force that?
pulls the denser, cooler material downwards due to its higher density compared to the surrounding fluid. This sinking force is driven by gravity and the natural tendency of denser materials to settle at the bottom of a fluid.
What causes the convection cell to turn down at point c?
The convection cell turns down at point c due to cooling of the air parcel at that elevation. As the air cools, it becomes denser and starts to sink. This sinking motion creates a downward convection flow in the cell.
How do plates move where convection currents are sinking?
When convection currents sink near the mantle, they create drag on the lithospheric plates above. This drag causes the plates to move in the direction of the sinking current. As the plates move, they can interact with other plates, leading to processes like subduction or mountain formation.
What make fluids rise and sink in a convection current?
Fluids rise and sink in a convection current due to differences in temperature and density. When a fluid is heated, it becomes less dense and rises, creating an upward flow. As it cools, it becomes more dense and sinks, creating a downward flow. This continuous cycle of heating and cooling drives the convection current.
Which process causes transfer of energy by air current within earth atmosphere?
convection
What do you need for convection to occur?
Convection occurs when there is a difference in temperature that causes a fluid (liquid or gas) to move. This movement is driven by the warmer, less dense fluid rising and the cooler, denser fluid sinking. The presence of gravity is also essential for convection to occur.
What causes the global air convection current between the equators and the poles?
earths tilt (apex)
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
An increase in wind causes this current to increase What type of current is it?
Convection is the process that causes warm air to rise and cold air to sink. As such, the winds caused by this process are called convection currents.
Density causes hot plastic-like rock to be forced upward towards the surface to cool and then sink. This cycle is called a current?
