This movement is known as convection, where warmer air or liquid rises and cooler air or liquid sinks. In cities, temperature differences can create convection currents that affect the movement of air and pollutants, leading to localized changes in temperature and air quality.
The movement of material due to differences in density caused by differences in temperature is called convection.
The movement of material due to differences in density caused by differences in temperature is called convection. Warm, less dense material rises while cooler, denser material sinks, creating a circulating flow within a fluid.
When there are differences in temperature, material moves through conduction, convection, and radiation. Conduction is the transfer of heat through a material. Convection is the movement of fluids due to temperature differences. Radiation is the transfer of heat through electromagnetic waves.
Convection. This process involves the transfer of heat through the movement of a fluid (liquid or gas) driven by variations in temperature and density.
This movement is called convection. As material is heated, it becomes less dense and rises, while cooler, denser material sinks. This creates a circular motion that helps transfer heat through a fluid or gas.

Movement of material caused by differences in temperature is known as thermal expansion. When materials are heated, they expand due to increased kinetic energy of the particles. Conversely, when materials are cooled, they contract or shrink. This phenomenon is utilized in applications like thermostats, bimetallic strips, and expansion joints.
Convection
Convection is the movement of fluid caused by temperature differences, transferring heat from one part of the fluid to another. It is an important process in heat transfer and can occur in liquids and gases.
Thermal currents are caused by temperature differences in a fluid, leading to the vertical movement of the fluid. Amp density differences can create electrical currents in a conductive medium, such as in electrolytes within batteries or in electrical circuits.
The movement of a fluid caused by differences in temperature is known as convection. Hotter regions of the fluid will rise due to lower density, while cooler regions will sink, creating a circulating flow pattern. This process helps distribute heat throughout the fluid.
Temperature differences in the mantle drive convection currents because warm material is less dense and rises, while cooler material is more dense and sinks. This movement creates a circular flow as the cooler material sinks and gets heated, while the warmer material rises and cools down. The density variations caused by the temperature differences are a key driver of convection in the mantle.
Convection is caused by temperature differences within a fluid (liquid or gas) and the resulting movement of the fluid due to these temperature variations. The two main factors that drive convection are heat energy transfer and density differences in the fluid.
