Convection is the movement of heat because of the movement of warm matter.. For example, atmospheric circulation moves warm air to cool places, causing wind.Wind, in turn, can enter and cool a room if the window is open. The movement of the clouds, the ocean currents and many types of heaters are examples of convection.4 days ago · 2. Thunderstorm: A thunderstorm can be the best example of convection currents. The warm water in the air rises upwards and turns into saturated water drops which form the clouds. In this process, the smaller clouds run into each other and hence the bigger clouds are formed. A water particle in the convection cycle can take 1600 years to complete the cycle. More dense water masses will sink towards the ocean floor. Just like convection in air, when denser water sinks, its space is filled by less dense water moving in. This creates convection currents that move enormous amounts of water in the depths of the ocean. What causes the convection currents in the mantle? It is caused by the difference in temperature and density. Heating and cooling of the fluid, changes in the fluid density, and the force of gravity, combine to set convection currents in motion.

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.The differences in the temperature at the Earth’s interior and surface cause convection currents to occur within the mantle. Lithospheric plates are the parts of the uppermost layer of the Earth, and they are flowing in an area called the asthenosphere. The asthenosphere is a soft, less rigid upper part of the mantle where the lithospheric plates float and move …Just like a hot-air balloon lifting off the ground, blobs or "parcels" of hot air rise from the ground, carrying hot air skyward. This transfer of heat energy away from the ground by the vertical movement of air is called "free convection" or "natural convection." A hot air balloon rises because warmer air is less dense than cool air. A current is the steady flow of a fluid (such as air or water) within a larger body of that fluid. Prevailing winds are air currents that blow mainly in one direction. The global pattern of …Natural convection is when heat transfer is not generated by an external source.

These plates move slowly over the asthenosphere, a layer of softer rock below the lithosphere. On average, tectonic plates move a few centimeters per year. The place where two plates meet is called a plate boundary.Cold, salty water is heavy and sinks to great depths. This causes the circulation of millions of cubic metres of water in the ocean. This powerful phenomenon, which primarily occurs in a few polar regions of the ocean, is called convection. The surface water in the North Atlantic region sinks to a depth of around 2000 metres due to convection.The Earth's crust is broken up into pieces called plates. These plates move due to convection currents in the mantle . Heat from the core makes magma in the mantle rise …Large convection currents in the aesthenosphere transfer heat to the surface, where plumes of less dense magma break apart the plates at the spreading centers, creating divergent plate boundaries.

Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth’s crust.
An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. In California there are two …. Seafood restaurants in plymouth ma
Convection current movements create a push and pull effect, creating the volcanic trenches, which are formed when two plates collide. The friction between the plates cause one to melt, forcing the other to move downward and leaving a gap. If the magma continues to rise towards the surface of the gap, the formation of another volcano may …Convection takes place in the atmosphere, in the oceans, and in Earth’s molten subcrustal asthenosphere. Convective currents of air in the atmosphere are referred to as updrafts and downdrafts. In addition to heat transfer, convention can be driven by other properties (e.g., salinity, density, etc).The friction of these plates rubbing against each other causes melting of the oceanic plate and can cause earthquakes. Magma from deep in the Earth's mantle ...This heat transfer process occurs via convection, which creates currents within the mantle that ultimately cause the plates to move. Page 2. Overview of ...Explanation: A diagram may help here: This effect causes the equatorial regions to be heated considerably more, in turn heating the air masses above them which rise accordingly.

Surface currents are caused by wind, and affected by the rotation of the Earth and the gravity of the moon (tides).Convection is the rising motion of warmer areas of a liquid or gas, and the sinking motion of cooler areas of liquid or gas, sometimes forming a complete cycle. However, it is often difficult to see, particularly within the air. Nevertheless, if convective clouds form during a sunny day, they can often be observed growing in size and getting ... When liquids or gases get heated, their volume increases, making them less dense. Thus, the less desne region rises up, and makes way for the cooler and denser part of the liquid to take its place. This process is called convection. Thus, convection currents in air are caused by the heat on the earth's surface.Convection is heat transfer via the movement of a fluid, such as air or water.
