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.
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.
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.
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 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.

Wind

The energy from waves is usually caused by the wind; the wind is caused by temperature differences among different parts of Earth; and these temperature differences are caused by the sunlight.
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.
Density Current
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.
The word is "convection."
