What might cause convection currents in a hot spring?

What might cause a convection current in a hot spring? Heat and pressure in the mantle have caused soled mantle rock to warm and flow very slowly. Geologists think plumes of mantle rock slowly rise from the bottom to the top. The hot rock then cools and sinks back through the mantle.

Where the heat that causes the convection currents comes from?

Convection Currents in the Mantle Heat in the mantle comes from the Earth’s molten outer core, decay of radioactive elements and, in the upper mantle, friction from descending tectonic plates.

What causes convection current example?

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 causes weather convection?

Convection – When warm, moist air near the surface rises to be above the heavier cool, dry air this is a form of heat transfer or convection. The rising motion typically cools the air. As the air cools, it reaches the dewpoint and all of the moisture in the air condenses– forming clouds.

How are the convection currents set in motion quizlet?

Convection currents are set in motion by the transfer of energy between Earth’s hot interior and cooler exterior. Regions of hot mantle are less dense than areas of cooler mantle and are slowly forced toward the crust. Cooler parts of the mantle sink back toward the core.

In which part of Earth’s core do convection currents occur?

The heat rising from the Earth’s core creates convection currents in the plastic layer of the mantle (asthenosphere). The convection currents slowly move the tectonic plates above them in different directions.

What is the main causes of convection currents in the atmosphere?

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 cyclones?

Convection is the transfer of heat by the movement of a gas or liquid from one position to another. When they occur in our atmosphere, convection currents cause local breezes, winds, cyclones and thunderstorms. The action of convection currents also result in smog.
