Answer:
2. from the Sun to the surface of the Earth, where it is absorbed or reflected
Step-by-step explanation:
The solar radiations come from the Sun and enter the atmosphere to hit the ground of the earth. Part of the solar radiations is absorbed by the atmosphere and other materials present on the surface of the earth. The earth surface also absorbs part of the solar radiations.
However, the surface of the earth reflects some radiations back to space at night. Hence, solar radiations are released from Sun after which they hit the surface of the earth where they are absorbed or reflected.
