There is something in the water...

This last term we have been studing water and its relasted diseases. Here is a chart of an activitie we have done in class looking for information of the next diseases.

What is Malaria?

We created presentations talking about the different types of water-related diseases. My presentation is about Malaria.

Let's talk about dams...

Dams...

Advanteges:

• Produces energy
• Prevents Floods
• Stores water(supply)
• Improve Irrigation

Disadvanteges:

• Loss of habitats
• People forced to move 
• Expensive
• Less fertile downstream
• Danger of accidents
• Increase of water-related diseases

The Itaipu Dam...

The itaipu dam is located in the Paraná river next to Brazil. It's a hydroelectric dam with 12600 Mw. It was built as a result of the treaty signed the 26th of April 1973 when they decided the elctricity will be devided between the two countries.

Water over the world

In this video we can see two different types of lifes. The one of the girl, showing the life of lot of people who is living in these conditions due to their poor accessibility to clean and fresh water. On the other hand, the boy’s life is completely different as he has quick access to clean water. The boy tries to help the girl by changing her dirty water to clean one. This shows that in the world there is so much people in the position of the girl that need help and there is really few people with attitudes as the ones of the boy. Also this is trying to show that we should appreciate what we have as there is a person all around the world that dreams with having what you have.

Tropical Cyclons

A Tropical Cyclon is a localized, very intense low-pressure wind system, forming over tropical oceans and with winds of hurricane force. Depending to where this cyclons are form they will resive diferent names.If the cyclon is form in the Philipines in the North Pacific it will be called "Typhoons". If it's form in the Atlantic/ Pacific eastern ocean it will be called "Hurricane" an if it's located over the Indian/ South Pacific Ocean they will be called "Cyclones". The word Hurricane's origin is Taino Hurakán that means "god of the storm". This are named in an alfabetical order and one female name and male name.

Hurricanes are form when warm air rises, causing an area of lower air pressure bellow. Air from surrounding areas with higher air pressure pushes in to the low pressure area. Then that "new" air becomes warm and moist and arises, too. As the warm air continous ro rise, the surrounding air swirls in to take its place. As the warmes, moist air raises and cools off, the water in the air forms clouds. The whole system of clouds and wind spins and grows, fed by the ocean's heat and water evaporating from the surface. For a hurricane tu occure the weather  conditons  are that  warm, humid wind of tropycal water (80°F) warm water meets wind from west Africa, causes water to vaporize. Water vapor rises to atmosphere were it liquifies, this creates deuds(cumulonimbus), tall colums that makes thunderstorms as the clouds from them creates a spiral over ocean surface. Rain from thunderstorm falls to the ocean where is reheated and sent back to atmosphere. 

The Hurricane's wind speed and strengh is messure by scales from 1 to 5. This scale prevent possible damages.Hurricanes reaching category 3 and higher are considered major huricanes because of their potential of significan loss of life and damage. Category 1 and 2 storm are still dangerous, however, and requiere preventative messures. Depending on the scale of the hurricane thir will be effects and this effects will be grouped into 2, weather and economic. The weather effects are storm surge, floods and winds. The impacts on the economic are that anytime there is a disaster caused by a natural phenomenon there is extensive damage to property. People's livelihoods are wiped away and may take many years to get things together again. In many cases, there are fatalities and entire communities are severaly affected. This effects can be reduce by warmings such as drills, boards on doors and windows and supplies(food, radios, water).

What happen when plates move?

Mount Saint Helens

In the class of EM we study different natural desasters, in my case Mount sait helens

Earth movements

1rst video: The first video talks about how volcanos are made.

The hot rocks moves the plates, 1 plate beggins to lose hits, the other plate enter to the rocks, gas get´s hot and melt the rock and excape. When it´s goes out of the plate the melt rock get cold and form a volcano that have a hole that is conected with the magma but can't exape because when the magma gets hot it makes rock.

2nd video:The second video talks about ''PANGEA''

• Before the countries  separate they were together forming one only country name ''PANGEA''.Pangea was the only land in all the world. Pangea desapear when the plate tectonics start to move  and tanformed pangea in the countries we know now. That's why a part of Africa match with South America. Think of this Brazil next to Nigeria, Buenos Aires next to Africa, Chile next to New York, California next to Sitney. That would be interesant for me.
• It was very interesant the video and I learned a lot of it.
