00:00:00,000 --> 00:00:14,259
Hi, today we are going to explain you the atmosphere.

2
00:00:14,259 --> 00:00:22,649
Now we are going to talk about the greenhouse effect.

3
00:00:22,649 --> 00:00:30,339
First of all, there are two types of greenhouse effect, the natural and the anthropic.

4
00:00:30,339 --> 00:00:35,340
The natural greenhouse effect is a natural process that warms up the Earth's surface.

5
00:00:35,340 --> 00:00:39,340
It happens when the sun's energy reaches the Earth's atmosphere.

6
00:00:39,340 --> 00:00:43,939
Some of it is reflected back to space and the rest is absorbed and re-varied by greenhouse gases.

7
00:00:44,340 --> 00:00:47,460
And the anthropic can be also called caused by the man.

8
00:00:48,500 --> 00:00:55,159
The anthropic component of the greenhouse effect is caused by man's activities that emit greenhouse gases to the atmosphere.

9
00:00:55,500 --> 00:00:58,640
Now we're going to talk about the hole in the ozone layer.

10
00:00:58,979 --> 00:01:06,319
The hole in the ozone layer has shrunk thanks to the ban of CVCS.

11
00:01:06,319 --> 00:01:13,159
Yes, NASA has confirmed that after finding that chlorine levels are quickly declining in Earth's stratosphere.

12
00:01:14,000 --> 00:01:17,099
And last but not least, we're going to talk about the acid rain.

13
00:01:19,379 --> 00:01:22,879
The acid gases from the fabric rise into the atmosphere.

14
00:01:24,840 --> 00:01:31,120
And the gases carried upwards by the wind, they combine with water droplets and form acids.

15
00:01:31,959 --> 00:01:33,859
They form acid rain.

16
00:01:33,859 --> 00:01:41,719
acid rain destroys plants pollutes water sources and soil and erodes buildings

17
00:01:41,719 --> 00:01:48,370
such as the tree we just seen the end we hope you've enjoyed this video and

learned a lot with it this video was made by Sofia and Elena
