To Start With

Listen to the dialogue. Can you answer the questions?

Bella: I think a drought has set in. It hasn’t rained a drop for months.Arik: I think so, too, but didn’t it rain last month? Bella: It did rain last month, but the rainfall was only half the monthly average. Arik: Oh. That bad?! Bella: That’s right. It’s really bad. I’m really concerned though not panicked yet.Arik: I don’t blame you. The pastures have browned out even before the dry season hasn’t arrived. Bella: Yeah, and the soil has been baked so hard that the plow can’t even break the soil. Arik: Looks like it’s going to be an ongoing thing that would get worse

each day.Bella: Yeah. If it doesn’t rain, it’s going to get critical.Itcan devastate crops and livestock. Arik: Faced with such hardship, many farmers may sell up and move to cities.

Expressing Cause and Effect

Here are some sentences you hear in the dialogue.• That’sbecause you can’t open a newspaper or watch television these days

without seeing report after report about threats to the environment.• Millionscouldbedrivenfromtheirhomesbecause of rising sea levels.When we talk about an effect resulting from a certain cause, we use expressions such

as: because, since, as, for,owing to, due to...

Examples:• Localflightsintheareaweredelayedbecause of the storm.• Wehavebeenlivingundertheopenskysincethefloodinundatedourvillage.• As the hurricane gained speed and intensity, residents of the coastal areas began

to prepare for the storm.• Thefarmersighedfor the drought had killed the corn.• Owing to the bad weather, we cancelled our holiday.• Everyonewasaskedtovacatetheareadue to the landslide warning.

You can also express cause and effect as follows:• Thecauseof…is…• …iscausedby/isdueto…• Thanksto...

Examples:• The cause of global warming is the increase of greenhouse gas in

the environment.• Globalwarmingis caused by the increase of greenhouse gas in

the environment.• Globalwarmingis due to the increase of greenhouse gas in the environment.• Thanks to the good weather, the vines developed well throughout the year.

Things to remember about cause and effect:• Due to, because of, owing to and thanks to are followed by a noun.• Because, since, as and for are followed by a subject + verb.• Peopletendtousethankstoinpositivesituations.

Understanding the Water Cycle

Source:parablesforkids.blogspot.comHave you ever thought about where

the water in your glass may have come from? Can you guess how old it is? Have you ever thought that you might be drinking dinosaur water?

The water you drink today could be the same water Tyrannosaurus rex drank millions of years ago. Yes, the water in your glass may have fallen to the ground the last time it rained, but that water could be as oldastheEarthitself.Infact,theamountof water on the planet today is the same amount that was here when dinosaurs roamedtheEarth.

The water that helped the first living things survive in theEarth’s seas,oceans,lakes, and rivers is available to us through the water cycle, the movement of water from the planet’s surface to the sky and back again. The water cycle is made up of a few steps that are always at work and happen over and over again.

The first step in the water cycle is precipitation. Precipitation happenswhenwatervapour(waterasagas;steam)comes together. Energy from the sunprovidesthe fuel for this process. When so much water has formed in the air that cloudscannot hold it anymore, the clouds become heavy, and the water they contain

fallsto the ground as snow, sleet, rain, or hail. Precipitation fills the Earth’s lakes,rivers,streams, seas, and oceans with water.

The water that falls to the ground because of precipitation does more than just fillthe planet’s waterways (oceans,rivers,etc.); italsohelpsshapetheEarth’ssurface.Think about rivers and streams, forinstance:Theyneverflowinastraightlinebecause the force of water creates their curvy paths.

But there’s much more to water than what appears on the planet’s surface.This valuableresource,whichfallstotheEarthas precipitation, is also soakedup and stored underground in collection areas called aquifers, which supply groundwater, or water which is stored in the ground.This underground water is pumped straight from the aquifers and is oftenused as drinking water.

PeoplearenottheonlyspeciesonEarththatneedwatertolive,however.Plantsalsodepend on this vital resource. Some plants get their water through a process called transpiration, or the loss of water from the leaves of plants.

This vapour then travels back into the atmosphere(themassofairthatsurroundstheEarth)throughaheatingprocesscalledevaporation, or the change of water from


a liquid to a vapour. Transpiration and evaporation work hand in hand to return water vapour to the air.

When water vapour in the atmosphere cools, it changes back to a liquid, the most common form of water, and forms clouds through a process called condensation. Condensation occurs when water vapour changes from a gas to a liquid. If the water droplets form close to the ground, that’s fog. When there is a lot of water vapour in the atmosphere, clouds get heavy with water.When that happens,precipitationfallstotheEarth,

and the water cycle begins again.Think of the water cycle like a big

recyclingprogram. To recycle is to use something overand over again—and that’s howtheEarth’swaterworks.Itneverstopsmoving;it just changes forms.

ThewatercycleisthewaytheEarthusesand recycles water. Water moves from theEarthtotheskyoverandoveragain.Andthat’s how we’re still drinking the samewater dinosaurs drank millions of years ago.

Task 12 Read the text.What is it about?

How Is Acid Rain Formed?

Rain is very important for life. All living things need water to live, even people. Rain brings us the water we need. But in many places in the world even where you live, rain has become a menace. Because of pollution in the air, acid gases from factories, cars and homes, the rain is becoming dangerous for the life of every living creature. This rain is known as ‘acid rain’.

The process begins when certain pollutants are released into the air. Once airborne, these gases react with other atmospheric constituents to form various secondary compounds, including acids.Thisprocess is dominatedbynitrogenoxides (NOx) andsulfurdioxide(SO2)gasemissions.

NOxandSO2chemicallyreactintheatmospherewithwater,oxygen, and other substances to form sulfuric acid (H2SO4),nitricacid(HNO3),sulfateparticles(SO4),andnitrateparticles(NO3).Thecompoundsarethencarriedthroughtheatmosphere,sometimes over great distances, and are deposited to the earth whenthereisrain,snow,orfog.WhenacidrainreachesEarth,itflowsacrossthesurfaceinrunoffwater,enterswatersystems,andsinks into the soil.

Acid rain has many ecological effects, but none is greater than its impact on lakes, streams, wetlands, and other aquatic environments. Acid rain makes waters acidic and causes them to absorb the aluminum that makes its way from soil into lakes and streams. This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals.

How Do Hurricanes Form?Hurricanes are the most awesome,

violentstormsonEarth.Peoplecallthesestorms by other names, such as typhoons or cyclones, depending on where they occur. The scientific term for all these storms is tropical cyclone. Only tropical cyclones that form over the Atlantic OceanoreasternPacificOceanarecalled“hurricanes.”

Whatever they are called, tropical cyclones all form the same way.

Source:spaceplace.nasa.govTropical cyclones are like giant

engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves

up and away from the surface, there is less air left near the surface. Another way to say the same thing is that the warm air rises, causing an area of lower air pressure below.

Air from surrounding areas with higher air pressure pushes in to the low pressure area. Then that “new” air becomes warm and moist and rises, too. As the warm air continues to rise, the surrounding air swirls in to take its place. As the warmed, moist air rises 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.

Storms that form north of the equator spin counterclockwise. Storms south of the equator spin clockwise. This difference is becauseofEarth’srotationonitsaxis.

As the storm system rotates faster and faster, an eye forms in the center. It is very calm and clear in the eye, with very low air pressure. Higher pressure air from above flowsdownintotheeye.


When the winds in the rotating storm reach 39 mph, the storm is called a “tropical storm.” And when the wind speeds reach 74 mph, the storm is officially a “tropical cyclone,” or hurricane.

Tropical cyclones usually weaken when they hit land, because they are no

It is common for it to happen around Christmas,which iswhy itwascalledElNiño.“ElNiño”means“theBoyChild”,referring to Baby Jesus, although it has nothing to do with little boys or girls.

TheEarthisfullofwater.Someofitevaporates.Butwheredoesitgowhenitevaporates?You already know that clouds are made of water and that they precipitate the water back to the ground. But did you know that this all is part of the water cycle?

The water cycle is made up of four main parts: evaporation and transpiration, condensation, precipitation, and accumulation.

When the sun shines on the ocean, warm air rises and forms water vapour. This process is called evaporation.


The next stage is condensation. The water vapour in the air condenses into lots of tiny drops of water, so small we cannot see them. This warm moist air rises up into the sky.As the water vapour rises high up in the sky the air gets cooler. The water vapour condenses making the tiny drops of water in the vapour a bit bigger.

They are no longer invisible and form a cloud. The clouds may be blown towards the landandprecipitationasrain,hailorsnowoccurs.Precipitationbringsthewaterbacktotheground where it originated.

The next part of the water cycle is accumulation. It is when water from precipitation is stored in a river, lake, underground, or other place until it is evaporated and goes back into the cycle.
