How does water get up to the atmosphere, and how does it get back down to earth surface
IrinaK [193]

Answer:

Water gets up to the Earth's atmosphere by evaporating from a body of water, which is then they become water vapor. It returns back to the surface by returning back to its water state and falling back down (as rain). The water vapor turns into clouds (clouds are really just water droplets), and when it cannot hold anymore waters, it disperses all the water (by raining).

A substance is known to reflect red and blue light. What color would it have when it is illuminated by green light?
oksian1 [2.3K]

Answer:

A substance known to reflect red and blue light, and illuminated by green light, will have all the three primary light colors. The color it would reflect is white.

Explanation:

In visible light spectrum, a combination of red light and blue light gives magenta. Also a combination of red and green lights gives yellow light. and when green and blue lights mix the resulting light color is cyan.

However, if these three primary colors mix in equal proportion, we will have a neural color or white color and in the absence of these primary colors we will have black.

Thus, a substance known to reflect red and blue light, and illuminated by green light, will have all the three primary light colors. The color it would reflect is white.
