1
00:00:00,000 --> 00:00:01,604
Pojďme si trochu popovídat

2
00:00:01,604 --> 00:00:04,328
o koloběhu vody, který je
nám všem dobře známý.

3
00:00:04,328 --> 00:00:06,096
Všichni jsme totiž jeho součástí,

4
00:00:06,096 --> 00:00:07,509
každý okamžik našeho života.

5
00:00:07,509 --> 00:00:09,312
Možná že to nedostatečně oceníme.

6
00:00:09,312 --> 00:00:11,011
Tak se vrhněme na ten koloběh.

7
00:00:11,011 --> 00:00:12,706
Začnu s vypařováním.

8
00:00:12,706 --> 00:00:15,288
Mohli bychom začít zde s povrchem oceánu,

9
00:00:15,288 --> 00:00:17,695
nebo s touto řekou, nebo s tímto jezerem.

10
00:00:17,695 --> 00:00:19,066
A v každém okamžiku

11
00:00:19,066 --> 00:00:22,068
se bude voda vypařovat z povrchu.

12
00:00:22,068 --> 00:00:24,832
Molekuly vody, které
byly v kapalném stavu,

13
00:00:24,832 --> 00:00:28,644
v kapalném stavu mají dostatek
energie, aby vyrazily pryč

14
00:00:28,644 --> 00:00:30,811
a aby se přeměnily do plynného stavu.

15
00:00:32,919 --> 00:00:37,069
A vodu v plynném stavu
nazýváme pára, vodní pára.

16
00:00:37,069 --> 00:00:38,652
Vodní, vodní pára.

17
00:00:41,441 --> 00:00:45,395
Takže vodní pára bude stoupat,

18
00:00:45,395 --> 00:00:49,685
pravděpodobně se vzduchem,
který se ohřál na povrchu,

19
00:00:49,685 --> 00:00:54,304
vlivem slunce a ve hře
je mnoho další dynamiky.

20
00:00:54,304 --> 00:00:57,548
Ale jak stoupá a jak celková teplota

21
00:00:57,548 --> 00:01:01,715
klesá, vodní pára se
vysráží do malých kapiček.

22
00:01:02,646 --> 00:01:04,869
Vysráží se okolo malých,
drobných částic vzduchu,

23
00:01:04,869 --> 00:01:06,953
malých částic prachu,
které ani pouhým okem

24
00:01:06,953 --> 00:01:09,847
nevidíte a to je tím,
co vytváří oblaka.

25
00:01:09,847 --> 00:01:14,014
Takže tohle jsou malé částice

26
00:01:16,292 --> 00:01:19,323


27
00:01:19,323 --> 00:01:23,513


28
00:01:23,513 --> 00:01:26,947


29
00:01:26,947 --> 00:01:31,114


30
00:01:31,961 --> 00:01:33,422


31
00:01:33,422 --> 00:01:37,572


32
00:01:37,572 --> 00:01:40,556


33
00:01:40,556 --> 00:01:42,450


34
00:01:42,450 --> 00:01:45,841


35
00:01:45,841 --> 00:01:48,447


36
00:01:48,447 --> 00:01:51,025


37
00:01:51,025 --> 00:01:52,598


38
00:01:52,598 --> 00:01:55,964


39
00:01:55,964 --> 00:01:58,888

00:02:09,463 --> 00:02:10,968
