Attempt

1 of 3

Drag and drop the boxes into the correct order.

Reorder the following stages of the enhanced greenhouse effect from first to last.

The radiation is rereleased as outgoing long-wave infrared radiation
which means that the temperature of Earth is rising
But some of that radiation is absorbed by greenhouse gases
Most of the radiation reaches the surface, where it is absorbed, causing warming
Humans are increasing the concentration of greenhouse gases in the atmosphere,
This energy is short-wave ultraviolet radiation
The greenhouse gases re-emit the energy, causing it to scatter in all directions – some back to Earth, where the warming is amplified
Solar radiation is released by the Sun
Some of the outgoing radiation is lost to space
Some of this incoming radiation is reflected back to space by the atmosphere and clouds
