IX)-Read the passage carefully, and then answer the questions below.

Neptune, like the other gas giants in our solar system, doesn’t have much of a solid surface to live on. However, the planet’s largest moon, Triton, might make an interesting place to set up a space colony.

So far, only a spaceship has ever flown flew by Neptune and its system, and was able to photograph the southern hemisphere of the moon.

Images show that Triton's surface is mostly made up of rock and nitrogen ice, and there are smooth areas next to volcanos. The smooth areas are formed by clouds of dust and nitrogen gas which erupt from the volcanos.

VOCABULARY AND GRAMMAR I. Match a word in column A with its description in column B, writing the answer in each blank. Answer A B ______ 1. A thunderstorm A. It is created when the surface layer of the ground collapses. It varies in size and are found all over the world. It is an area of ground that has no natural external surface drainage. When it rains, all of the water stays inside it and typically drains into the subsurface. It can vary from a few feet to hundreds of acres and from less than 1 to more than 100 feet deep. ______ 2. A tornado B. The Earth has a crust under the oceans and the land that we live on. This crust made of massive areas of flat rock called tectonic plates, which float on the Earth’s mantle, the inside layer of the Earth. When the plates move slowly together, this movement forces energy through the crusts to the Earth’s surface. The energy causes the Earth to tremble and shake. ______ 3. A hurricane C. It is a very bright flash of electricity that happens in a thunderstorm. It is actually a spark that crosses the gap between two clouds or between a cloud and the Earth. It carries an enormous charge of electricity. Trees are burned, metal can be melted and people can be killed. ______ 4. An earthquake D. It is caused by earthquakes at sea. It forms when energy from an earthquake displace hundreds of cubic kilometers of water from the seabed. Large waves begin moving through the ocean from their epicenters. When it reaches shallow water near coastal areas, it increases in height. The sign comes before it strikes when the waterline suddenly retreats, exposing hundreds of meters of beach and seabed. ______ 5. A volcano E. It is a very violent windstorm. The air is concentrated and whirls up rapidly. It is grey in colour and looks like an elephant’s trunk swaying down from the clouds to touch the ground with its tip. ______ 6. A tsunami F.

CLIMATE CHANGE AND GLOBAL WARMING

Climate change

Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires.

The green house effect

While other planets in Earth's solar system are either scorching hot or bitterly old, Earth's surface has relatively mild, stable temperatures. Earth enjoys these temperatures because of its atmosphere, which is the thin layer of gases that cloak and protect the planet. However, 97 percent of climate scientists agree that humans have changed Earth's atmosphere in dramatic ways over the past two centuries, resulting in global warming The exchange of incoming and outgoing radiation that warms the Earth is often referred to as the greenhouse effect because a greenhouse works in much the same way. Incoming UV radiation easily passes through the glass walls of a greenhouse and is absorbed by the plants and hard surfaces inside. Weaker IR radiation, however, has difficulty passing through the glass walls and is trapped inside, thus warming the greenhouse. This effect lets tropical plants thrive inside a greenhouse, even during a cold winter.

Consequences of global warming

There are two major effects of global warming: the increase of temperature on the earth by about 30 to 50C (5.40 to 90Fahrenheit) by the year 2100 are Rise of sea levels by at least 25 meters (82 feet) by the year 2100. Other consequences are listed below:

• Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice.

• Amounts and patterns of precipitation are changing.

• The total annual power of hurricanes has already increased markedly since 1975 because their average intensity and average duration have increased.

• Changes in temperature and precipitation patterns increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts heat waves, and tornadoes.

• Higher or lower agricultural yields, further glacial retreat, reduced summer stream flows, species extinctions.

• Diseases like malaria are returning into areas where they have been extinguished earlier

Which is the world's highest, driest, coldest and windiest continent? Which is the only place on Earth not yet ruined, still untouched by the destructive hand of man? Australasia? Or "the ice", as Antarctica is referred to by its old friends? Of course, the former still has 5 large areas as yet untouched, but nothing like the huge virgin expanses of "the ice".

 Now, the virgin continent has become the source of yet another conflict between scientists and enviromentalists. The latter believe that 10 Antarctica must be maintained as such and that scientists should be careful not to leave behind anything that might damage the environment. Scientists say that limited local environmental impact has to be expected and accepted, because the continent is an important natural laboratory for estimating the effects humans have on the globe, even 15 functioning as a kind of early - warning system for the whole planet. There is a treaty designed to protect this continent which has only 8000 inhabitants and most of them not permanent, but contains 70% of the world's fresh water. Oil and minerals cannot be exploited, 20 but what controls are there on the growing number of scientists, explorers and even tourists?

1. According to the passage what is the main reason for the conflict between the scientists and the environmentalists?

A. The possible emvironmental damage 

B.  The use of Antarctica as a laboratory

C.Antarctica is becoming a tourist spot

D. Antarctica is being used as an early - warning system

2. What can be inferred from the passage?

A. Antarctica cannot be saved

B. Antarctica has too few inhabitants to worry about

C. Antarctica is worth saving

D. There is a treaty about Antarctica, so there is nothing to worry about

3. What is the synonym of " Permanent"?

A. Everlasting

B.  Unstable

C. Worthy

D. Costly

4. What is the main topic of the passage?

A. Australasia

B. Iceland

C. Antarctica

D. The Ice Continents
