convection current
Yes, that is correct. Convection currents are caused by differences in density within a fluid, leading to the movement of the fluid in response to changes in temperature or composition. This movement helps transfer heat and can be seen in various natural phenomena like the circulation of air in the atmosphere or the movement of magma in the Earth's mantle.
Convection is the movement of matter resulting from differences in density. This occurs when warmer, less dense fluids rise and cooler, more dense fluids sink. Convection plays a critical role in various natural phenomena, such as atmospheric circulation and ocean currents.
Convection is a movement in a fluid that occurs due to differences in density. Warmer, less dense fluid rises, while cooler, denser fluid sinks, creating a continuous cycle of movement. This process is observed in Earth's mantle, where hot magma rises and cooler rock sinks, driving tectonic plate movement.
Conduction is the transfer of heat through direct contact between objects, such as a pan on a stove. Convection, on the other hand, is the transfer of heat through the movement of fluids, such as air or water, which results in a circulating current.
The density of molecules affects heat transfer by determining how closely packed the molecules are. Higher density means more molecules per unit volume, leading to more efficient heat conduction. Lower density results in slower heat transfer due to fewer molecules available for heat energy to be transferred through.

radition
This is known as convection, where warmer, less dense matter rises and cooler, denser matter sinks. This process occurs in fluids like air and water, contributing to the circulation of heat and nutrients in the Earth's atmosphere and oceans.
Diffusion is the transfer of energy within a particular field from high density particles to lower density. ie. Hot air will always want to move to cold air because there is less resistance with cold air. Osmosis works the same way only with water transferring over a membrane towards less resistance. From high water potential towards low water potential. Good question.
Convection is an energy transfer process that occurs only in fluids like liquids and gases. It involves the transfer of heat through the movement of the fluid itself, which results in the circulation of the fluid and the transfer of heat from one place to another.
It plays a number of roles. First, the tectonic plates essentially float on the asthenosphere because they are less dense. Second, since oceanic crust is denser than continental crust, it can subduct into the mantle while continental crust cannot. Plate tectonics is driven in part by mantle convection, which results from variations in density due to temperature differences.
