Here is one way we can create
fresh

water
using
technology .....
The processes of taking salt out of salt

water in order to make it

fresh
water
Introduction
Now and days there is a lack of water and the amount of fresh water is decreasing by the

second
. But there are different ways that we can create
new
water from the
technology
we have today.
Another way we can create
water
using
technology
is....
How Technology Effects
Water

In this presentation you will be learning
about different ways technology effects
water. The presentation is mainly about different ways we can "create" water using technology.

Desalination Is ....
How Does it work?
There are many of taking salt out of saltwater but here is the main one:
Reverse Osmosis :
The salt water is put under high pressure and flows through a membrane. This membrane has holes in it that only allow water molecules to go through it ( therefore the salt molecules are left behind) and that makes the water fresh water.

Fresh water
Cloud Seeding

Cloud seeding is .....
When you shoot substances into clouds in order to make it rain
How does it work ?
Substances ( such as silver iodide) are shot into clouds. These substances give the cloud moisture a base to condense on and form into ice crystals . when the crystals become too heavy they fall down as rain. Usually it takes a long time for the cloud moisture to form into ice crystals , but cloud seeding makes it faster.
Connections :
This will effect countries that have no/only a little amount of fresh water, because there will be more fresh water so those countries will also get some.
This will also effect those countries economies, because they will have more fresh water, so people will be healthier. Which means more of them will have jobs, which results in a better economy
Connections:
This will effect the environment, because by doing this we can create more rain which will help plants and wildlife grow there
This will effect countries that have droughts/ desserts because then there will be more rain there, which will improve the environment (and could potentially improve there economy) .
This will also effect humans and animals that live there,because it will make it easier for them to survive ( they will have more water and plants as well).
Conclusion
To conclude Desalination and Cloud Seeding are 2 ways we can create
water
using
technology.

1. Silver Iodide is sprayed into the clouds
2. Ice crystals form around silver iodide
3. Ice crystals become too heavy and fall out as rain
