I. Read the following text and answer the questions below.

        Mars is a planet. It is the fourth planet from the sun. It is the next planet beyond Earth. Mars is more than 142 million miles from the sun. The planet is about one-sixth the size of Earth. Mars is known as the Red Planet. It gets its red colour from the iron in its soil. Mars has two small moons. Their names are Phobos and Deimos.

        Mars is very cold. The average temperature on Mars is minus 80 degrees Fahrenheit - way below freezing!

        Mars is rocky with canyons, volcanoes and craters all over it. Red dust covers almost all of Mars. It has clouds and wind, just as Earth does. Sometimes the wind blows the red dust into a dust storm. Tiny dust storms can look like tornados, and large ones can cover the whole planet!

        Mars has about one-third the gravity of Earth. A rock dropped on Mars would fall slower than a rock dropped on Earth. Things weigh less on Mars than they weigh on Earth. A person who weighs 100 pounds on Earth would only weigh about 37 pounds on Mars because of less gravity.

The ancient Egyptians named the planet Her Descher meaning the red one.

Before space exploration, Mars was considered the best candidate for harboring extraterrestrial life. Astronomers thought they saw straight lines crisscrossing its surface. This led to the popular belief that irrigation canals on the planet had been constructed by intelligent beings. In 1938, when Orson Welles broadcasted a radio drama based on the science fiction classic War of the Worlds by H.G. Wells, enough people believed in the tale of invading Martians to cause a near panic.

Another reason for scientists to expect life on Mars had to do with the apparent seasonal color changes on the planet's surface. This phenomenon led to speculation that conditions might support a bloom of Martian vegetation during the warmer months and cause plant life to become dormant during colder periods.

Otherwise Pluto will become too far from Earth and it will be more difficult to get near the planet. The New Horizons mission is important because no spacecraft has ever been sent that far before. The information collected during this mission will help to explain what the outer edges of the solar system look like and how the solar system was formed 4.5 billion years ago. * NASA: National Aeronautics and Space Administration * the Solar System: the Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, IJranus, Neptune, Pluto

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. It is a hill or mountain formed when molten material or lave from the inside of the Earth is forced through the Earth’s crust by gases. It can produce vast clouds of very fine volcanic dust which looks like smoke. ______ 7. A sinkhole G. It is a storm where you hear thunder and see lightning. There is usually heavy rain.

THE TEXT:

Nowadays humans are still wondering what planets in outer space might support life.

Scientists say planets need to meet three main conditions to support life. Firstly, they must have liquid water, so their temperature must not be too high or too low. Secondly, the planets need to have the correct amount of air so that they can hold an atmosphere around. Finally, their size is also important. If a planet is too small, its gravity is not strong enough to hold an enough amount of air. If it is too big, its gravity will be so strong that it will hold too much air.

Scientists are using space telescopes to find habitable planets. According to them, Mars is one of the most promising planets for life in our solar system. It is a planet like Earth. Its days last for 24.5 hours and its seasons are similar to Earth's. Although scientists have not found actual water on Mars, there seems to be traces of it on the planet's surface. However, the climate on Mars is unsuitable for human life because it is too cold and Mars lacks oxygen to support human life.

It is home to millions of species of plants and animals. including a global population of humans. Life on Earth is supported and nourished by its biosphere and minerals. Scientists are looking for other planets to accommodate our increasing population. They believe that if humans could trace water on Mars and plant trees, they could increase the amount of oxygen on the planet. That would greatly increase the chance of humans being able to live on it in the future.

VI. Read the text and classify the following statements.

There are eight other planets that travel around the sun. These planets, in order, include Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Earth is located between Venus and Mars. The path the planets use when traveling around the sun is oval-shaped and is called its orbit. Each of the planets in the solar system take a different amount of time to orbit the Sun.

Earth takes 365 days or one year to orbit the Sun. The other planets take more or less time to orbit the Sun. It takes Mercury 88 days to travel around the Sun, which is the shortest orbit time compared to other planets. The planet taking the longest time to go around the Sun is Neptune. It takes Neptune almost 165 years to travel around the Sun.

Normally, planets located closer to the sun are hotter than planets farther away. Mercury is the planet nearest the sun, and it can have a temperature of 427°C– much hotter than an oven. Venus is not the planet nearest the sun, but it is the hottest, because it has thick clouds. These clouds let the sun’s heat in, but do not let it out. The temperature on Venus can be 460°C.

The four inner planets, Mercury, Venus, Earth, and Mars are made of rock containing many different minerals.
