In the troposphere, air temperatures: decrease with decreasing altitude. decrease with increasing altitude. increase with increasing altitude. increase with decreasing altitude. none of the above is correct.

In troposphere air temperature decreases with increase in altitude.

Explanation:

When the sun rays hit the surface of earth it absorbs the energy of sunlight and after some time the heated surface of earth emits heat which increases the temperature in the lower regions of the troposphere while the top layer of the troposphere is cooler than the regions below hence the variation.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
