Remember what layers the atmosphere consists of. Indicate which atmospheric layer corresponds to each of these characteristics.

Layers of the atmosphere: troposphere, stratosphere, mesosphere, thermosphere, exosphere
a) The lowest layer of the atmosphere – the troposphere
b) The composition is dominated by hydrogen – the thermosphere
c) Contains 80% of the mass of air – exosphere
d) extends to a height of 50 km – the stratosphere
e) The sky here is black – the exosphere
f) Almost all water vapor is present – the troposphere
g) Contains the ozone layer – the stratosphere
h) Very low air density – exosphere
i) Weather changes occur – the troposphere
j) Located above the troposphere – the stratosphere
