4 Positive effects of diffusion Negative effects of diffusion

5 What is diffusion? Positive effects of diffusion. Negative effects of diffusion. Bibliography

6 What is diffusion? It is a spontaneous intermingling of two different, bordering gases, liquids or solids, occurring due to the movements of molecules. Diffusion occurs at all temperatures.

7 Positive effects of diffusion
We can smell beautiful scents of flowers, plants and perfume. Insects, attracted by the scent, find food and at the Same time pollinate plants.

8 Plants produce oxygen which is
spread around There is the possibility of creating chemical solutions and mixtures in nature Diffusion has enabled creation of matter in the universe

9 Negative effects of diffusion
Viruses and bacteria which cause infectious diseases are spread around Harmful gases and liquids are transferred, which adversely affects the Earth’s atmosphere Ozone holes and acid rain appear

10 Surface water and groundwater
become easily contaminated owing to oil-tanker catastrophes, municipal and liquid industrial wastes Soil contamination by all kinds of dust and industrial waste, chemical fertilizers and pesticides

13 Negative physical phenomena in the environment

14 Let’s think, what we can do to prevent the negative effects of these phenomena.

15 This is the hole people talk about so much.

16 Acid rain, acid snow and such is the snowman.

17 You know, doggy, we are passive smokers.

18 They are all covered in oil. What will happen to them?

19 I deluded myself that this river might be clean.

20 Hey buddy, read the signs!

26 Niebezpieczna fala

27 Fala to zaburzenie, które się rozprzestrzenia w ośrodku wodnym lub powietrznym.

28 Fala może stanowić dla nas atrakcję…

29 Fala może także nieść śmierć…

30 Tsunami – fala portowa

31 Tsunami – fala portowa

32 Przyczyny powstawania tsunami.

33 Erupcja podwodnego wulkanu

34 Podwodny wstrząs tektoniczny
Nagłe osunięcie lub wypiętrzenie fragmentu dna

35 Asteroida uderzający w Ziemię

36 Tylko znajomość mechanizmu powstawania tsunami oraz metod wczesnego diagnozowania zjawisk powodujących tsunami, może uchronić nas od tragedii. Możliwości diagnozowania stwarza fizyka.
