Convection Cycles Give Rise to Which of the Following

All of the above By signing up. When the air is close to the ground it heats up and rises when it gets up high it cools down and therefore sinks.

Convection Currents Conduction Radiation Posters Convection Currents Convection Conduction

This cycle is a convection current.

. When droplets build up in the clouds sufficiently the result. In a convection current there is hot and cold air. Naturally two of the biggest cycles where convection currents tend to take place include the movement of the magma in Earths mantle and that of the air in the atmosphere.

As it rises it pulls cooler fluid down to replace it. When the dewpoint is below 0C which of the following is likely to form. A cycle of moving material formed by the sinking and rising of high-density material.

All of the preceding. View Answer Hide Answer. A cycle of moving material formed by the rise of denser material and the sinking of less-dense material.

Sometimes convection currents also tend to stress the lithosphere and the cracking that follows as a result takes place in the form of earthquakes. In weather it describes the vertical transport of heat and moisture in the atmosphere usually from a warmer area the surface to a cooler one aloft. Change in molecular structure of a fluid.

The wind is mainly caused when the reflected radiation of. Going by the definition of convection the molecules at a higher temperature displace the ones at a lower temperature. Convection causes the air which is closer to the land surface to heat and hence rise.

Convection currents are present in the air A good example of convection current is the warm air that rises towards the ceiling in your house. Another good example of convection current is wind. From a meteorology perspective convection is just an upward motion of air in the atmosphere.

This sounds simple enough but it can lead to severe weather in certain conditions. Change in density of a fluid. Generally natural convection occurs due to.

A form of precipitation that results from convection cycles in the clouds is. The less dense heated fluid rises away from the heat source. The initial heat transfer between the object and the fluid takes place through conduction but the bulk heat transfer happens due to the motion of the fluid.

Jet stream rivers of air. Convection is the process of heat transfer in fluids by the actual. A hot liquid or air that expands becomes less dense and rises or becomes more.

A land breeze b sea breeze c air currents d all of the preceding. Change in density of a fluid. The process happens as the warm air is said to be less dense than that of the colder air.

The Earth is made out of a number of different layers and though we live on the. Convection may also take place in soft solids or. The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise and.

A cycle of moving material formed by the rise of less-dense material and the sinking of denser material. This fluid in turn is heated rises and pulls down more cool fluid. 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.

Convection cycles give rise to which of the following. Convection explains why hot air balloons rise and also why it is often hotter in the lofts of houses than downstairs. Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids.

As heated air rises for example it pulls cooler air into its place -- where it can be heated rise and pull in more cool air. Convection currents form because a heated fluid expands becoming less dense. A more scientific definition of convection is.

Q h c A T s T f Where Q is the heat transferred per unit time. When the cause of the convection is unspecified convection due to the effects of thermal expansion and buoyancy can be assumed. For water droplets to form what must be present.

Convection is basically when a liquid gets hot rises cools down moves to the side and back to the bottom to get hot again. Mark me as Brainliest. The best example of convection is a pot of boiling water.

The water cycle takes water above below and on the surface of the earth. While the word convection is sometimes used interchangeably with thunderstorms remember that thunderstorms are only one type. None of the above.

The water cycle also known as the hydrologic cycle never ends. Buoyant masses of visible water droplets or ice crystals. Convection currents rely on the constant cyclical motion of air water and other substances to distribute heat.

Convection is a term youll hear quite often in meteorology. H c is the coefficient of convective heat transfer. As well as these examples convection is seen on a much bigger scale in our.

What is the definition of CONVECTION. A is the area of heat transfer. When heat transfers from objects that are touching.

Change in velocity of a fluid. The equation to calculate the rate of convection is as follows. Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid most commonly density and gravity.

Convection cycles give rise to which of the following. Which of the following is formed by direct freezing of water droplets. Convection currents are the movement of fluid as a result of differential heating or convection.

Convective clouds - When the air has a lot of moisture the convection currents will carry that moisture up into the sky to form convective clouds. When heat transfers through waves. T s is the surface temperature.

Similarly in the afternoon the surface of the land near the sea is warmer as compared to in the evening.
