Five examples total of events causing weathering and erosion ( explain)

1. One event that can cause weathering and erosion is rain. This causes erosion through the process of washing dirt and small rocks off of hills, mountains, and other surfaces.

2. The next event that can cause weathering is wind. This causes erosion because it picks up small materials from the earth and transports them somewhere else.

3. The third event capable of erosion is human interference. Throughout the years that humans have been on Earth, the land has changed incredibly. People cause erosion and weathering through walking, building, and moving things like trees or flowers.

4. The fourth event that causes erosion is a tsunami. Tsunamis are huge waves of water that crash over beaches and places near ocean shores. When this happens, it often washes away vast amounts of land and possibly buildings with it.

5. The final thing that causes weathering is glacial ice. Glacial ice is known as a large amount of frozen water grouped up together, forming a glacier. When these glaciers melt or move, the land under or around it is changed as well. Land is pushed forward or moved backward due to the movements.

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
