25,000 = 2.5 x 10^4
250 = 2.5 x 10^2
0.025 = 2.5 x 10^-2
0.00025 = 2.5 x 10^-4 :D
Answer:Ozone layer
Explanation:
In the stratosphere, we find the ozone layer that protects life on Earth from ultraviolet radiations.
Most part of Ultraviolet radiaton is absorved by the earth's ozone layer. All of ultraviolet UVC is absorbed and most of UVB.
Almost all of the ultraviolet radiation received on Earth is UVA. UVA and UVB radiation can both affect health.
When a flood occurs, the stream is getting much more water, and on the parts where the angle of fall is greater and the stream is faster, because of the greater amount of water, and thus force, it managed to take with it much bigger amount of sediments, and also much bigger pieces of it.
The transportation depends on the speed and force of the water, and when there is a flood. both of those are bigger, so the stream is able to carry more sediments over a longer distance, but also over a wider area as the waters are getting out of the normal river flow and flood the valley.
