- Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath. Along with the turning of the Earth, this movement of air creates winds. Winds, in turn, create surface waves on the ocean. Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents.

- The warmer air cools, away from the heat source, and falls. The cooler air warms at the ground level and rises. This causes convection cycles in the atmosphere, and by extension wind (which is moving air). Written Nov 6, 2015 · View Upvotes.

How are convection currents responsible for the movement of the plates in the earth? When the current cools down more, the convection current descends again and goes to the inner earth. There the temperature increases and the current rises again. This goes on and on. The heat of the Earth's core is a mixture of two sources. The first is the. initial heat from the formation of the planet.

- Figure 4.1: Solar radiation warms the earth’s surface, triggering convection whichcarries heat vertically to the emission level from which, because the atmosphereabove this level is transparent in the IR, energy can be radiated out to space..6 Convection in the atmosphere We have seen that the atmosphere is normally stable in the absence of con-densation. Hence most convection in the atmospheric is moist convection, ac-companied by saturation and hence cloud formation.

How convection currents form? Making the world better, one answer at a time. Convection currents form in the earth's asthenosphere (the middle mantle) due to heat from the core. They can also form in any other fluid (scientifically, a fluid can be either a liquid or gas), such as boiling water, hot soup, and even the air. But let's use the asthenosphere as an example because it's a good one.

General Circulation of the Atmosphere The circulation cell closest to the equator is called the Hadley cell. Winds are light at the equator because of the weak horizontal pressure gradients located there. The warm surface conditions result in locally low pressure.The warm air rises at the equator producing clouds and causing instability in the atmosphere. This instability causes thunderstorms to develop and release large amounts of latent heat.he warm surface conditions result in locally low pressure.

General Circulation of the Atmosphere General Circulation of the Atmosphere body. The circulation of wind in the atmosphere is driven by the rotation of the earth and the incoming energy from the sun. Wind circulates in each hemisphere in three distinct cells which help transport energy and heat from the equator to the poles. The winds are driven by the energy from the sun at the surface as warm air rises and colder air sinks.

- Convection currents are identified in Earth's mantle. Heated mantle material is shown rising from deep inside the mantle, while cooler mantle material sinks, creating a convection current. It is thought that this type of current is responsible for the movements of the plates of Earth's crust.

Currents in the Earth's System Convection currents in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere. The aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the Earth that extends to 2900 km.

Convection Currents in Earth Convection Currents in Earth. In Earth’s mantle, large amounts of heat are transferred by convection currents, as shown in Figure 10. Heat from the core and the mantle itself causes convection currents in the mantle. Figure 10Mantle Convection Most geologists think that convection currents rise and sink through the mantle.

Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Currents are cohesive streams of seawater that circulate through the ocean.urrents may also be generated by density differences in water masses caused by temperature and salinity variations. These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them. Occasional events also trigger serious currents. Huge storms move water masses.

How are convection currents responsible for the movement of the plates in the earth? Convection currents are movements in (and of) the liquid part of our earth due to differences in temperature. The warm rises and the cool sinks. But the cool which has sank will be heated (the heater, the core, is at the bottom) and the warm, which has risen, will be cooled.

- Heat from the Earth's core  causes convection currents in the mantle, and these cause the  plates to move around over millions of years. This movement is  often referred to as continental drift because the relative  positions of the continents change because of it.   Earth is liquid inside.

The Earth's Layers Lesson #1 Convection currents are caused by the very hot material at the deepest part of the mantle rising, then cooling, sinking again and then heating, rising and repeating the cycle over and over. The next time you heat anything like soup or pudding in a pan you can watch the convection currents move in the liquid. When the convection currents flow in the mantle they also move the crust. The crust gets a free ride with these currents. A conveyor belt in a factory moves boxes like the convection currents in the mantle moves the plates of the Earth.

Atmospheric circulation Photo by: Hynek Kalista. Atmospheric circulation is the movement of air at all levels of the atmosphere over all parts of the planet. The driving force behind atmospheric circulation is solar energy, which heats the atmosphere with different intensities at the equator, the middle latitudes, and the poles.s air is heated at the equator, it rises in the troposphere, the lowest 10 miles (16 kilometers) of Earth's atmosphere. In the wake of the warm rising air, low pressure develops at the equator.

Earth's Interior/Plate Tectonics Convection currents in the astheosphere cause the plates to move constantly but slowly. The hotter, less dense rock rises. While rising it cools making it more dense. Once it is cool and becomes more dense, it starts to sink.

convection For example, air on a part of the Earth's surface warmed by strong sunlight will be heated by contact with the ground and will expand and flow upward, creating a region of low pressure below it; cooler surrounding air will then flow in to this low pressure region. The air thus circulates by convection, creating winds. See Note at conduction.

Geography for Kids Convection. The final way that heat is transferred from one place to another is convection. Convection takes place when heated molecules move from one place to another, taking the heat with them. Convection is common in both the atmosphere as well as in the oceans. .menuItem { font-family: verdana; font-size: 10pt; color: #990000; text-decoration: none; }. Heated air in our atmosphere expands, becoming less dense. Because it is less dense, it rises upward. Cooler air rushes in to replace the air that lifted up. As warm air rises and cool air falls, a giant circular pattern is created. Eventually the warmer air cools and begins to fall again. Convection also takes place within the Sun.

Mantle convection A superplume generated by cooling processes in the mantle. Mantle convection is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior of the Earth to the surface. The Earth's surface lithosphere, which rides atop the asthenosphere (the two components of the upper mantle), is divided into a number of plates that are continuously being created and consumed at their opposite plate boundaries.

What Causes Convection Currents? There are also convection currents in the atmosphere, which help form both weather and clouds, as well as creating wind and major air currents similar to the ocean currents.
