The amount of solar energy that reaches Earth is nearly constant. Why are different parts of Earth warmer than others?
The tilt of the Earth's axis influences how much solar energy reaches parts of the NH and SH.

500
The part of the electromagnetic Spectrum has the smallest or lowest frequency.
What is radio waves?

Explain red shift and blue shift
Red shift is a measure of stars moving away from an object causing the wavelengths to lengthen. Blue shift is when a star is moving closer to an object causing the wavelengths to shorten
