What Are The Convection Currents (2023)

1. What Are Convection Currents? - Sciencing

  • Apr 23, 2018 · Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock.

  • Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it.

  • convection currents occur when a heated fluid expands, becoming less dense, and rises. The fluid then cools and contracts, becoming more dense, and sinks. Convection currents are an important form of heat transfer. Convection occurs when heat cannot efficiently be transferred through radiation or thermal conduction. In astronomy convection currents occur in the mantle of the Earth, and presumably some other planets, and the convection zone of the sun. Inside of the Earth, magma is heated near the core, rises toward the crust, then cools and sinks back toward the core. It is thought that this motion is responsible for the movement of the Earth's crust. In the sun, convection occurs when opaque gas absorbs energy emitted by fusion, heats up, and rises to the photosphere, where the energy is radiated into space. You can see convection cells in pictures of the Sun's surface. Convection also occurs in a pot of boiling water, or a convection oven

What are the Convectional currents? ›

Convection currents are movements of fluid caused by a temperature or density difference within a material. Convection currents are only seen in gases and liquids because particles within a solid are fixed in place. Warm air rising toward a house's ceiling or attic is a simple example of convection currents.

What are the convection currents in the Earth quizlet? ›

The continuous cycle of magma rising and falling in the Earth's mantle is called a Convection current. The movement of magma causes friction between the tectonic plates. This friction causes the plates to move. The movement of the plates causes events like volcanic erruptions, earthquakes and tsunamis.

How many convection currents are there? ›

Three major convection cells drive the prevailing weather patterns, climate, and ocean currents. The Hadley cells consist of warm, moist air rising at the equator.

What are convection currents in the Earth's oceans? ›

Convection in the ocean occurs when dense (cold and/or saline) water overlies lighter (warmer or fresher) water. Convective events occur primarily when water is cooled (or becomes more salty) at the ocean surface.

What are 7 examples of convection? ›

10 EXAMPLES OF CONVECTION
  • Boiling Water.
  • Land and Sea Breeze.
  • Air Conditioner.
  • Body blood circulation.
  • Melting of chilled drinks.
  • Convection Oven.
  • Hot-air Baloon.
  • Refrigerator.

What is a convection current for kids? ›

When the fluid molecules are heated, the fluid becomes larger and lighter. The heated molecules take up more space and rise to the top, while the cooler molecules sink to the bottom. These cooler molecules then become heated. The process is repeated. This cycle is called the convection current.
