Where does convection occur in the earth?
mantle Convection currents are identified in Earth's mantle. Heated mantle material is shown rising from deep inside the mantle, while cooler mantle material sinks, creating a convection current. It is thought that this type of current is responsible for the movements of the plates of Earth's crust.
What is an example of convection in Earth’s system?
Wind is an example of a convection current. Sunlight or reflected light radiates heat setting up a temperature difference that causes the air to move.
How does convection occur?
Convection occurs when there is a difference in thermal energy in a liquid or a gas. The area with greater thermal energy causes an increase in temperature, or molecular kinetic energy. This causes the molecules to move faster and spread out, decreasing the density of the substance.
Does convection occur in solids?
No, convection currents are not possible in solid. Convection is heat transfer by mass motion of a fluid such as air or water. Convection does not occurs in solid because the particles within are tightly packed to facilitate the process.
What are 4 examples of convection?
In this article, we are going to discuss the real-life examples of convection which are quite interesting.

- Hot Air Balloon.
What are some examples of convection?
Everyday Examples of Convection radiator – A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea – The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting – Ice melts because heat moves to the ice from the air.
Can convection occur in liquids?
Convection happens in fluids (liquid and gases). The heat energy moves the material in liquids and gases because when they all are heated they expand and become less dense. For the formation of convection currents it is important for the particles to move freely upto a certain extent.
Does convection only occur in liquids?
Convection only happens with fluids, materials that can flow. Liquids can flow (think of water) and gases can flow (think of wind). Solids are stuck in place so they can't flow and since they can't flow, there is no convection. The way heat transfers through solids is conduction.
What are 5 examples of convection that occur in everyday life?

What are the three examples of conduction?
Some examples of heat conduction could be the following:
- A lizard warming its belly on a hot rock.
- Touching a hot seatbelt when you get into a car.
- A blacksmith heating up a sword in hot coals, and the heat transferring up through the metal.
- The heat from a stovetop transferring into a metal pot of water.

Which situation best represents convection?
Which situation best represents convection? A hot air balloon taking off.
Which of the following is an example of convection?
Convection is a form of heat transfer where a large number of molecules move from one place to another. An overhead fan works precisely by this method: it sends cooler air molecules down into a hot room, cooling the temperature of the room.
Can convection occur in gas?
Convection only happens with fluids, materials that can flow. Liquids can flow (think of water) and gases can flow (think of wind). Solids are stuck in place so they can't flow and since they can't flow, there is no convection.
Which is the best example of convection?
Everyday Examples of Convection boiling water – When water boils, the heat passes from the burner into the pot, heating the water at the bottom. This hot water rises and cooler water moves down to replace it, causing a circular motion.
Which of the following situations is an example of conduction?
Conduction: Touching a stove and being burned. Ice cooling down your hand. Boiling water by thrusting a red-hot piece of iron into it.
What are examples of convection?

Is Sweating an example of convection?
Heat from the skin is required for sweat to evaporate from the skin, but without air flow, the air becomes saturated and evaporation stops. Air flow caused by convection replaces the saturated air by dry air and evaporation continues.
