Where do Earth’s convection currents occur? the lithosphere
tectonic plates
the asthenosphere
the subduction zone

The asthenosphere

Explanation:

Heat is generated from the radioactive decay of elements in the interior of  the Earth, which creates magma in the asthenosphere. Hope this helped

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

the growth of the plants is affected by the heat of the light. what is the student doing?
