The atmospheric temperature decreases when snow starts melting because the snow releases thermal energy from the atmosphere to melt. answers

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.

it is b. absorbs thermal energy

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .
