The sun moves about 1 degree to the east every (one earth) day relative to the stars. It takes the Sun one year (365.25 earth days) to make a full circle and return back to its original spot.
Gravity causes mass movement. Types of mass movement: landslides, mudslides, slump, and creep. The most destructive kind of mass movement is a landslide, which occurs when rock and soil slide quickly down a steep slope.
Answer:
Visible light range (between 400 and 800 nm).
Explanation:
The Sun emits a large range of electromagnetic waves, from gamma rays (higher frequencies) to radio waves (lower frequencies), through X-rays, ultraviolet rays, visible light, infrared radiation, microwaves. The peak of the Sun's energy output is actually in the visible light range (between 400 and 800 nm).
In the graph I annexed, you can see a simplified representation of the energy emissions of the Sun versus the wavelengths of those emissions. The y-axis shows the amount of energy emitted at a given wavelength and the x-axis represents different wavelengths of EM radiation. In this graph is observable than the major emission of radiation emitted by the Sun is in the visible range.
I hope you find this information useful and interesting! Good luck!
