What are the main causes of convection currents in the atmosphere

Answers

Density and temperature

Option (A) is correct. The main cause of the convection currents in the asthenosphere is density and temperature.

Further Explanation:

The convection current in any medium is the shifting of the less denselayer upward and bringing the denser layers of the medium downward.

In other words, the convection current is set up when there is a significant variation in the density and the temperature of the different layers of the medium. The continuous movement of the warm layer up and the cold layer down leads to the convection current in the medium.

From the above explanation, it is clear that the convection current set up in any layer is due to the variation in the density and in the varying temperature range. The weight and the pressure of the layer do not play any significant role in setting the convection current.

Thus, Option (A) is correct. The main cause of the convection currents in the asthenosphere is density and temperature.

Keywords:  Asthenosphere, convection currents, density, temperature, warm layer, cold layer, dense, less dense, density and temperature.

The correct answer is a) Density and temperature.  

Explanation:

The earth has a mantle between the nucleus and the crust that is divided into the inner mantle that is solid and elastic, and the outer mantle that is fluid and viscous.

In the mantle of the earth, the asthenosphere is identified, it is located below the lithosphere, which is characterized by its solid region and when influenced by high temperature, it becomes a moldable element, also by being closer to the surface of the earth's temperature can be 300 to 500 degrees Celsius.

Therefore, the density and temperature characteristics are the main cause of convection currents in the asthenosphere. Convection currents are distinguished by heat transfers from one site to another through moving fluids.

The convection currents in the asthenosphere are significant because through them, the movements of technical plates that have the function of the formation of mountains and the new life through the changes produced by the convection currents are produced.

I hope this information can help you.

Hey there!

What are the main causes of convection currents in the asthenosphere?


. Density and temperature

Hope this helps! (:

The answer is A) Density and temperature. Hope it helps and I am 99% sure it is right.
The main causes of convection currents in the asthenosphere is A. density and temperature. Convection currents are formed from gradients such as concentration and temperature gradients. Density is the one closely related to concentration gradient. Answer hence is A>

A. Density and temperature

Explanation:

The correct answer would be density and temperature.

Explanation:

C) Density and Temperature
In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath.
