Answer:
Earth takes in thermal energy from the Sun in a process called THERMAL RADIATION.
Sunlight strikes Earth's surface at different angles. This angle is called the angle of INCIDENCE.
Step-by-step explanation:
It is thermal radiation because thermal radiation refer to process where electromagnetic waves are emitted from a body or matter whose temperature is higher than zero. The Earth take in thermal energy from the sun as a result of thermal radiation.
Angle of incidence is the angle between a ray of light and the surface of it's perpendicular direction. The sunlight strike the Earth surface at an angle called angle of incidence.
