Earth is the third closest planet to the Sun in the Solar System. It's the only planet whose English names, the World or the Earth, don't come from Roman or Greek mythology but from Olc English and Germanic. It is also referred to as the Blue Planet, or the Blue Marble because it's the only planet that has water in liquid form on the surface. In fact, seventy-one per cent of Earth's surface is covered with water, which is vital for all known forms of life. Earth is the only planet than is capable of hosting any known form of 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.

Câu 16: Earth is the planet from the Sun in our solar system.

A third

B. fifth

C. second

D. fourth

Câu 17: What is the life on Earth supported by?

A. its global population of humans.

B. its species of plants and animals.

B. its biosphere and minerals.

D. its water in liquid form.

Câu 18: What is the percentage of Earth's surface which is covered by water?

A. 71%

B. 75%

C. 65%

D. 81%

Câu 19: Are scientists looking for other planets to accommodate our increasing population?

A. Yes, they are.

B. Yes, it is.

C. No, it isn't.

D. No, they aren't.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

As viewed from space, Earth’s distinguishing characteristics are its blue waters and white clouds. Enveloped by an ocean of air consisting of 78% nitrogen and 21% oxygen, the planet is the only one in our solar system known to harbor life. Circling the Sun at an average distance of 149 million kilometers (93 million miles), Earth is the third planet from the Sun and the fifth largest planet in the solar system.

Our planet’s rapid spin and molten nickel-iron core give rise to an extensive magnetic field which, coupled the atmosphere, shields us from nearly all of the harmful radiation coming from the Sun and other stars. Earth’s atmosphere protects us from meteors as well, most of which burn up in the Earth’s atmosphere before they can strike the surface. The planet active geological processes have left no evidence of the ancient pelting it almost certainly received soon after it formed about 4.6 billion years ago. The Earth has a single natural satellite – the moon.

Question. The word distinguishing as it is used in this selection means ________.

A. elevating in nature

B. characteristics like all other planets

C. devastating in nature

D. characteristics that set it apart from other planets
