Complete then copy into your books.

Note at GCSE we say heat rather than energy

Drugi mogući odgovor:

As the Earth’s surface gets warmer, it emits more energy.

Some energy is absorbed by greenhouse gases and transferred back to the Earth’s surface.

Energy is transferred from the Sun to the Earth’s surface.

Some reflected energy is transferred to space.

Most energy is absorbed by the Earth’s surface, making it warmer.
