Prior to the mid 20th century, the Colorado River flowed continuously from the Rocky Mountains to the Gulf of California. Since this time, several major projects have taken water away from the river's natural course One of these projects has been the
Colorado River Aqueduct
, which takes water from the Colorado river and transports it to the Los Angeles area for drinking water
Today, dunng many times of year, the Colorado River no longer reaches the Gulf of California
The dam pictured
below takes water from the Colorado River so it can be transported along the aqueduct On the night, a dried. up portion of the river in Baja California is shown
This example illustrates that
OA. human activities can vastly change how water flows along the Earth's surface.
ОВ.
humans are helpless to change the way that water flows along the Earth's surface.
OC. water flows in unpredictable ways and cannot be used for human purposes.
OD. a changing climate can bring floods to some areas and droughts to others

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.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
