jacob described two layers of earth's atmosphere.

layer a: contains the air we breathe
layer b: absorbs x-rays

which statement is most likely true?

layer a is the troposphere and layer b is thermosphere.
layer a is the thermosphere and layer b is troposphere.
layer a is the exosphere and layer b is the thermosphere.
layer a is the thermosphere and layer b is the exosphere.

A. Layer A is the troposphere and Layer B is thermosphere

Explanation:

The troposphere is the lowest layer of the atmosphere. THis is where all life life resides and where weather occurs as well. It contains the air we breathe. As we go higher in the troposphere, the temperature goes down.

The thermosphere is part of our atmosphere but it is very high up and considered to be part of outerspace as well. It is heated up by the UV rays and X-rays that it absorbs.

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.

a. an idea which cannot be disproven!
