Vocab words pg 229 1-5


1. List the main reasons for water scarcity

One of the main reason is low rainfall. Land degradation because then the water cannot infiltrate into the ground.

2. What is a drought? What type of hardships do you think that a drought could cause if you were living in a village in a poor country such as Ethiopia.

A drought is like there is barely any water and the air is not so moist. Living in Ethiopia while there is a drought must suck since Ethiopia does not have much water to begin with.

3.How does land degradation affect the supply of fresh water?

Because the water that rains cannot get into the ground so it cannot store fresh water.


4.(a)What is El nino? (b)Why does El Nino often cause drought in Australia?
El nino is the air getting warmer of the coast of Peru. It makes australia have droughts since all the moist wind that makes Australia moist gets blown away therefore causing it to have droughts.

5. (a)Observe the map showing the global effects of El Nino have on the availability of fresh water.
(b)Name the countries and describe the problems that arose from decreased rainfall caused by El Nino.

Australia, Wheat exports threatened by drought conditions across grain growing areas,particularly in new south whales. Papua new guinea, Drought related failure of food crops,leading to famine conditions requiring food aid. Peru, Flooding, Fishing operators affected by lower catch as anchovy and pacific sardine move offshore to escape warm currents(5 C above normal temperature). Colombia, Fishing operators affected by lower catch (down 20%). United states, Rainfall above normal in north western states(double the historical averages). Philippines, Lower rice harvest following drought. China, Agricultural land under threat from drought in northern regions and flooding in southern regions. Indonesia, High air pollution levels, following forest fires. Africa, Reduced corn crop in sub saharan region.

Bintaro Lama trip

Hello. Today I am going to tell you about my trip in bintaro lama and the stations I went to about cleaning the water in bintaro lama.

The first station I went to was station 5 where they teach you how to make sure that water is clean. First she gives us these tubes that has a cross at the bottom and fills it up with water. We then look down and you will see the cross is blurry. This means that the water is not clean. There are also other equipment like a thermometer to measure water ph levels.

Next the second station I went to was cleaning the water for taking a bath. They use a filter called a sand filter. How the sand filter works is that water is poured into it and the sand and rocks inside trap nearly all the dirt inside and then water comes out from a pipe into the bath tub with water clean enough to take a bath in.

The final station was station 3 where they clean water to make it potable. First they take a plastic aqua bottle and scrub the whole thing with soap. Next we shake the soap out with water. Then they fill it up with water and put in somewhere where there is sunlight and leave it there for six hours before they can drink it.

That is my trip in bintaro lama.

Water treatment plant trip

Hi. My name is William and I am going to tell you about how the water treatment plan cleans water and the steps to make water potable. You see there are a total of six steps to making it clean and i am going to tell you about each one.

The 1rst is cleaning water is to get the big and small but not microscopic dirt like soda cans or candy or paper for example separated from the water. They do this by first having these bars with a big enough gap in between to take out the big junk in the water. They then scoop up the junk into the garbage can every hour. Water the goes to another filter but this time it takes out the smaller dirt.

The 2nd step is they add chemicals to create flock. The chemicals are limestone,chlorine and one more thing.

The 3rd step is getting the flock to stay on the floor so it does not flow with the water therefore separating the dirt. The reason the flock is on the ground is because more dirt gathers so it becomes heavier.

The 4th step is the water that passed the first three steps go into a sand filter one meter deep. This is used to catch the really small dirt. They also use a special type of sand where most of the grains of sand has the same size.

The 5th step is they add chemical disinfects like chlorine to get rid of all those microscopic dirt particles. They do this so it becomes drinkable.

The final step is they make sure it is clean so they test it out by doing some stuff.

Those are the six steps to make water potable. But there are different ways to make water clean.

Splinter cell fallout


Splinter cell fallout is a book about a secret agent named sam fisher and he has to solve the mystery of his dead brother that somehow connects to a big terrorist organization.

The book was a bit of a disappointment but it was not bad. I mean at the first half it was interesting but at the second half it was really boring and it used a lot of words I did not understand. The characters for me were also not so interesting. Especially the main character since he was always so serious. I would give this *** stars.
