What is the movement of material due to differences in density that are caused by differences in temperature called?

What is the movement of material due to differences in density that are caused by differences in temperature called?

convection
Heat transfer by convection is caused by differences in temperature and density within a fluid.

Is the movement of material caused by the differences in temperature?

Convection is the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature.

What is the movement of matter that results from differences in density?

Convection is the term describing the upward and downward movement of air (or liquids). The underlying cause of these movements is differences in density. Density is the amount of matter in a given amount of space. Dense air sinks, creating downdrafts, while less dense air rises, creating updrafts.

What is any movement of matter that results from differences in density may be vertical circular or cyclical?

Question	Answer
any movement of matter that results from differences in density; may be vertical, circular, or cyclical.	convection current
the energy that is transferred as electromagnetic waves, such as visible light and infrared waves	radiation

Is the movement of matter due to differences in density that are caused by temperature variations and can result in the transfer of energy as heat?

A measure of hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object. The transfer of energy as heat through a material. convection. The movement of matter due to differences in density; the transfer of energy due to the movement of matter.

What is the movement of water due to differences in density?

There currents are set in motion by variations in water density caused by differences in temperature and salinity, a process called convection. The density of a substance is defined by its mass per volume; one liter of water, for example, does not weigh the same as one liter of oil.

What is caused by the action of hot material rising and cool material sinking?

Convection currents are the result of differential heating. 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.

How does differences in water temperature resulted in the formation of a convection current?

The heat energy can be transferred by the process of convection by the difference occurring in temperature between the two parts of the fluid. Due to this temperature difference, the hot fluids tend to rise, whereas cold fluids tend to sink. This creates a current within the fluid called Convection current.

What is the circulation of material caused by differences in density?

Natural convection, or free convection, occurs due to temperature differences which affect the density, and thus relative buoyancy, of the fluid. Heavier (denser) components will fall, while lighter (less dense) components rise, leading to bulk fluid movement.

Is a convection current Any movement of matter that results from differences in density?

Which type of proposal explains the kind of movement of material due to differences in density?

“LMS Ch 22 Concept Review

Question	Answer
the movement of matter due to differences in density that are caused by temperature variations; can result in the transfer of energy as heat	convection
the curving of the path of a moving object from an otherwise straight path due to Earth’s rotation	Coriolis effect

What causes differences in density?

A density difference can exist between two fluids because of a difference in temperature, salinity, or concentration of suspended sediment. Density currents in nature are exemplified by those currents that flow along the bottom of oceans or lakes.
