# Question: What Are Some Examples Of Convection Currents?

## How do convection currents move?

Explanation: The idea is that the heat from the earth’s interior causes convection currents in the magma.

The heat causes the some of the magma to rise toward the surface.

The convection currents in the magma moves the attached crust of the tectonic plates..

## What are 3 examples of conduction?

Everyday Examples of Heat or Thermal ConductionAfter a car is turned on, the engine becomes hot. … A radiator is a good example of conduction. … You can warm your back muscles with a heating pad.Roasting wieners over a campfire is fun until the heat from the fire is conducted up the coat hanger to your hand.More items…

## Is ice melting an example of convection?

Melting of Ice The melting of ice is yet another example of convection. The temperature of the surface or boundary of ice increases as warm air blows over the surface; or water, which is at a higher temperature as compared to the ice, flows underneath it.

## How do convection currents affect weather?

Atmospheric Pressure and Winds The heating of the Earth’s surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds.

## What are convection currents?

A convection current is a process which involves the movement of energy from one place to another. Convection currents tend to move a fluid or gas particles from one place to another. These are created as a result of the differences occurring within the densities and temperature of a specific gas or a fluid.

## How do you explain convection?

Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. Convection is a major factor in weather.

## How do ocean convection currents work?

Convection occurs because the oceanic waters heat up becoming less dense. This water moves above the cooler water, and give off its heat to the surrounding environment. As it cools, it begins to sink, and the process begins again. Convection results in the continual circulation of ocean water on a global scale.

## What layer of the Earth has convection currents?

Mantle convection is the very slow creeping motion of Earth’s solid silicate mantle caused by convection currents carrying heat from the interior to the planet’s surface. The Earth’s surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.

## Where do convection currents occur?

Answer and Explanation: Convection currents in the Earth occur in the mantle. The core of the Earth is extremely hot, and material in the mantle close to the core is heated…

## What food is cooked by convection?

When to Use the Convection SettingAny time you’re roasting: Foods that are roasted, like meats and vegetables, really benefit from convection cooking. … When baking pies and pastries: Convection heat melts fat and creates steam faster, which helps create more lift in pie doughs and pastries like croissants.More items…

## Is a fan an example of convection?

The hot air popper which is used to make popcorn also utilises the principle of convection. The hot air popper has a fan, vent, and a heating element. When the popper is turned on, the fan is employed to blow air on the heating element through the vent. The heating element, in turn, warms the air; which then rises.

## Is an ice cube melting conduction or convection?

For example, an ice cube in a glass of water eventually melts. This is because the heat from the water, which is warmer, flows to the ice cube until both are at the same temperature, and therefore no ice cube is left. There are three methods of heat transfer: conduction, convection, and radiation.

## Is boiling water convection or conduction?

Is boiling water convection or conduction? – Quora. Well, it is conduction through convection within the water. The water molecules are free to move around and thus form convection currents and try to bring the water to a uniform temperature.

## What are some examples of convection?

Everyday Examples of ConvectionBoiling water – The heat passes from the burner into the pot, heating the water at the bottom. … Radiator – Puts warm air out at the top and draws in cooler air at the bottom.Steaming cup of hot tea – The steam is showing heat being transfered into the air.More items…
