Question
Which statement best explains how atmospheric gases affect Earth's average temperature?(1 point)
Responses
The gasses warm Earth by allowing all Sun rays to travel to Earth's surface.
The gasses warm Earth by allowing all Sun rays to travel to Earth's surface.
The gases cool Earth by allowing most of the Sun's heat to escape into space.
The gases cool Earth by allowing most of the Sun's heat to escape into space.
The gasses warm Earth by trapping heat energy in the bonds between their atoms.
The gasses warm Earth by trapping heat energy in the bonds between their atoms.
The gasses cool Earth by decreasing the precipitation formed in the atmosphere.
The gases warm Earth by trapping heat energy in the bonds between their atoms.
In the troposphere, the bottom layer of Earth's air, the temperature changes from 17°C to −51°C, getting colder as you go higher. But in the layer above, called the stratosphere, the temperature goes up to −15°C as you go higher. Why does the temperature increase with altitude in the stratosphere?(1 point)
Responses
Because ozone absorbs energy from the Sun.
Because ozone absorbs energy from the Sun.
Because ozone reflects energy from the Sun.
