Radiant heating from the Sun warms the surface of the Earth. … In addition the Earth’s rotation moves warm water from the equator toward the poles resulting in ocean currents that move heat from the equator to the poles and pushes cold water from the poles toward the equator.

What are the 3 convection currents?
- the geosphere – plate tectonics. - the atmosphere - wind. - the hydrosphere - ocean currents.
What are convection currents where are they located?
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.
Why are convection currents important to weather?
Convection is the circulation (and mixing) of gases or liquid. On earth, this happens in air (which causes our weather), and in ocean currents. If for some reason convection stopped, air would not circulate, and weather would stop. Air wouldn't flow over the waters, suck up moisture and then rain it out on land.
How Do Ocean Currents Work? - Jennifer Verduin
What causes the global convection currents?
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.
What are convection currents called?
A convection current is a process that involves the movement of energy from one place to another. It is also called convection heat transfer.
What causes convection to form?
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.

What are the convection currents near the equator called?
Hadley Cells In the modern-day, the Hadley Cell is a term used to describe the rising of air near the equator, which then proceeds toward the poles at high altitude, returns to Earth around 30 degrees latitude, and moves back toward the equator at Earth's surface.
How do convection currents influence the climate?
Some currents are caused by convection, while others, called surface currents, are driven by wind. These currents move water all around the earth, bringing warm water to cooler areas and vice versa. This redistributes thermal energy and causes changes in the weather.
Convection Currents And The Coriolis Effect
What causes convection energy?
How does convection work? Convection works by areas of a liquid or gas heating or cooling greater than their surroundings, causing differences in temperature. These temperature differences then cause the areas to move as the hotter, less dense areas rise, and the cooler, more dense areas sink.
How is convection important in weather?
Importance of convection Convection is the rising of plumes of moist air in response to instability in the atmosphere. “The instability can be caused by cooling at the top or heating at the bottom. Either process creates deviations from stable conditions in the vertical temperature profile,” Peter explains.
