Convection currents are believed to stop corneal suffocation while sleeping. The rapid movements of the eye move the viscus fluid of the eye causing it to circulate and promoting oxygen flow.
Barbecuing, depending on what specific process it is referring to, could be either radiation, convection, or conduction. Radiation is when energy is released in the form of a photon, so the flames of the barbecue (light energy) are a form of radiation. Conduction is when energy is transferred through contact, or collision, therefore, the things you are cooking on the barbecue, are being heated through conduction with the metal. Convection is when energy travels through energy-containing particles (other than photons), so the steam rising from the coals is convection currents.
Tornadoes form during thunderstorm, which are driven by convection. Thunderstorms develop, in simple terms, when warm, moist air rises because it is less dense than surrounding cooler air. Part of tornado formation may also involve air sinking after being cooled by rain.
The heat is being transferred by convection.
The thermal energy that accounts for the movement of clouds is called convection. This occurs when warm air rises due to being less dense than the surrounding cool air, creating vertical air currents that carry clouds along with them.
convection. Heat from the lower floors rises, creating warmer temperatures upstairs.
Convection currents from the stove or microwave.
No, these are completely different. Light is an electromagnetic wave that can travel even in a vacuum (like space), whilst convection means transport of heat by currents of air or other medium, the currents being produced by the differences in density of the medium.
If you thing you are being suffocated reach for help. Go in well ventilated area to get some fresh air. If dealing with harmful chemicals read the label first to avoid inhaling fumes and to prevent yourself from getting suffocated.
Yes if your being suffocated :)
The asthenosphere is the layer of the Earth directly below the brittle lithosphere, made of solid rock with a small percentage of melt, which is under tremendous pressure and temperature conditions. It performs and moves in a ductile fashion (highly viscous) even though it is considered rock, and does not break while under stress, but can move due to convection currents of heat arising from Earth's interior.
because convection currents are caused by the liquid being heated, becoming less dense due to increased kinetic energy and rising. if you are heating the top of the test tube, there is nowhere for them to 'rise' to, so no current is formed, as they do not reach a place where they cool and sink to the bottom. thus convection currents are only formed when heating the bottom of a test tube.
The inner core is solid, but the mantle is the only layer of Earth that flows in currents. These currents are caused by convection. If you don't know what convection is then you might as well look it up because I don't have a good definition.
Constructive force caused by convection currents in the Earth's mantle is when hot material rises at divergent plate boundaries, creating new crust as it cools and solidifies. This process leads to the formation of mid-ocean ridges and new oceanic crust being produced.
Currents are measured in amps being I
The spinning motion of the paper snake when held over a Bunsen burner is due to convection currents created by the heat rising from the flame. As the air above the flame gets hot, it rises creating a low-pressure area that causes the paper snake to rotate. This is a demonstration of the principle of convection.
A convection current is a cycle. The way the cycle works is when the liquid is heated the particles become less dense as it rises to the top and then it becomes more dense so it comes back down again. Then the process starts again.
convection currents an example is a heat radiator...it radiates heat which warms the air. the air rises as its heated and cooler air takes its place then being heated by the radiator...this continues until the room is heated and so is a pot is on a stove and the water is boiling and the cold water is at the top and it goes to the bottom
