Question

convertion
Write a note on conduction
currents in atmosphere.​

Answer 1

Answer:

Conduction directly affects air temperature only a few centimeters into the atmosphere. During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction. At night, the ground cools and the heat flows from the warmer air directly above to the cooler ground via conduction.

Answer 2

1. The conduction current is the largest portion of the air.

2. far outweighing the contributions made by the precipitation current and convection current, which are zero in storm-free regions.

3. Its magnitude is approximately 3 × 10-12 amperes (A) m-2, or about 1800 A for the entire earth.

Hope it helps!
