Explanation:

4th statement is incorrect because this statement is correct regarding stratosphere.
Troposphere
•    It is the lowest layer of our atmosphere.
•    We humans live in the troposphere, and nearly all weather occurs in this lowest layer.
•    Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere.
Stratosphere
•    It extends from the top of the troposphere to about 50 km (31 miles) above the ground.
•    The famous ozone layer is found within the stratosphere.
•    Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat and hence here temperature rises with height.
•    Commercial passenger jets fly in the lower stratosphere, partly because this less-turbulent layer provides a smoother ride.
•    The jet stream flows near the border between the troposphere and the stratosphere.

Mesosphere
•    It extends upward to a height of about 85 km (53 miles) above our planet.
•    Most meteors burn up in the mesosphere. Unlike the stratosphere, temperatures once again grow colder as you rise up through the mesosphere.
•    The coldest temperatures in Earth's atmosphere, about -90° C (-130° F), are found near the top of this layer.

Ionosphere
•    The ionosphere is not a distinct layer like the others mentioned above.
•    Instead, the ionosphere is a series of regions in parts of the mesosphere and thermosphere where high-energy radiation from the Sun has knocked electrons loose from their parent atoms and molecules.
•    The electrically charged atoms and molecules that are formed in this way are called ions, giving the ionosphere its name and endowing this region with some special properties.
