Based on the choices provided, the outermost layer of the atmosphere is called the ___.
troposphere
stratosphere
thermosphere
mesosphere
Which layer has the coldest average temperature?
Troposphere
Stratosphere
Mesosphere
Thermosphere
Which statement best describes the ozone layer of Earth?
It helps reduce the amount of ultraviolet radiation reaching the surface of earth
It prevents the formation of severe storms in the stratosphere of Earth.
It increases the amount of nitrogen in the troposphere of Earth.
It forms a magnetic field in the mesosphere of Earth.
Generally, as altitude increases, temperature ___.
Increases
Decreases
Fluctuates
Stays constant (the same)
Which layer of the atmosphere has the highest density of gas molecules?
Exosphere
Mesosphere
Stratosphere
Thermosphere
Troposphere
In the troposphere, what is true about places at higher altitudes compared to places at lower altitudes?
they have cooler temperatures
they have warmer temperatures
they have the same temperatures
they have less predictable temperatures
In which atmosphere layer of Earth do thunderstorms occur?
thermosphere
mesosphere
stratosphere
troposphere
Which is associated with an increase of chlorofluorocarbons in the environment?
an increase in health risks with UV radiation.
an increase in levels of methane gas in the atmosphere
an increase in ozone levels in the upper atmosphere
an increase in acid precipitation.
Temperature increases as altitude increases in both the stratosphere and the thermosphere. What is the main difference between these two layers?
The temperature increases in the stratosphere because of aurora borealis, and in the thermosphere because of the jet stream.
The temperature increases in the stratosphere because ozone absorbs ultraviolet radiation, and in the thermosphere because of direct exposure to the sun.
The temperature increases in the stratosphere because of direct exposure to the sun, and in the thermosphere because ozone absorbs ultraviolet radiation.
The temperature increases in the stratosphere because of the jet stream, and in the thermosphere because of aurora borealis.
