WebConvection currents also stress the lithosphere above, and the cracking that often results manifests as earthquakes. According to. asthenosphere, zone of Earth’s mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere. The asthenosphere extends from about 100 km (60 miles) to about 700 km (450 ... WebConvection currents occur when a reservoir of fluid is heated at the bottom, and allowed to cool at the top.. Heat causes the fluid to expand, decreasing its density. If there is cooler material on top, it will be more compact and therefore, will sink to the bottom. The heated material will rise to the top.

Convection Currents and How They Work - ThoughtCo

WebConvection is the exchange of heat energy by the development of a liquid (fluid or gas) between regions of various temperatures. Warm air is less thick than cold air, thus convection flows are created within the sight of a temperature angle. At the point when flows are created distinctly by temperature-inferred density contrasts in the liquid ... WebThis occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. This lateral flow causes the plate material above to be dragged along in the direction of flow. At the crest of the uplift, the overlying plate is stretched thin, breaks and pulls apart. WebConduction occurs more readily in solids and liquids, where the particles are closer together than in gases, where particles are further apart. The rate of energy transfer by conduction … fischer ds1102vdyybkyy00d0544

What happens is that the cold water at the bottom heats up from the energy from the burner, and rises up. As the hot water rises, the cold water rushes in to replace it, which results in motion in the circular fashion. 3.
