118. layers of the atmosphere
[image] |
|
Definition
layers of the atmosphere is divided into five layers. The lowest level to the top is in this order:troposphere,stratosphere,mesosphere, and thermosphere.
All life is in the troposphere while planes planes fly in the stratosphere to be above all weather.

119. changing states of water
[image] |
|
Definition
Changing states if water is the transformation of any matter from one form to another, as in solid to liquid,liquid to gas,solid to gas,liquid to solid, and gas to liquid. Or also known as melting,evaporation,sublimation,freezing,and condensation.
Water easily makes a change of state at O.
