b) Scattering, after
c) Absorption, after
d) Reflection, after

Answer 1

Refraction is the process responsible for the Sun appearing above the horizon before it has actually risen. The correct answer is a) Refraction, before.

Step-by-step explanation:

The correct answer is a) Refraction, before.

Refraction is the process by which light bends and changes direction as it passes through a medium, such as air or water. When the sun is near the horizon, its light passes through a greater amount of Earth's atmosphere, causing the light to bend and appear above the horizon before it has actually risen.

This phenomenon is responsible for the early appearance of the sun in the morning and the prolonged presence of sunlight in the evening.
