5 billion years ago ... a nebula cloud of gas and rock began to come together by gravity. As it condensed, pieces of debris collided with each other ... and friction of their collisions ... heated the rocks! One of those hot new planets was our young Earth. Its interior, hot from friction and the decay of radioactive elements ... reached over 25,000°F. Slowly, that hot Earth developed a cooled, cracked crust. Those cracks formed the boundaries of a series of crustal Tectonic Plates ... that today, are broken into 17 pieces! The heat from Earth's formation... is incredibly, still trapped inside our planet! That rising molten heat forces our plates apart in some places ... and pushes them together in others! When plates pull apart ... a "Diverging Rift" develops! Volcanic eruptions occur here! When Continental Tectonic Plates collide... Mountains rise ... and Continents join! Terrible Earthquakes result! When Ocean Plates converge ... Volcanoes explode ... and Tsunamis drown thousands!!

Dịch giùm em ạ

5 tỷ năm trước ... một đám mây khí và đá tinh vân bắt đầu kết hợp với nhau bởi lực hấp dẫn. Khi nó ngưng tụ, các mảnh vỡ va chạm với nhau ... và ma sát va chạm của họ ... làm nóng đá! Một trong những hành tinh mới nóng bỏng đó là Trái đất trẻ của chúng ta. Bên trong của nó, nóng do ma sát và sự phân rã của các nguyên tố phóng xạ ... đạt trên 25.000 ° F. Dần dần, Trái đất nóng bỏng đó đã phát triển một lớp vỏ nứt nẻ, nguội đi. Những vết nứt đó đã hình thành ranh giới của một loạt các Mảng Kiến tạo lớp vỏ trái đất ... rằng ngày nay, được chia thành 17 mảnh! Sức nóng từ sự hình thành của Trái đất... thật đáng kinh ngạc, vẫn bị mắc kẹt bên trong hành tinh của chúng ta! Nhiệt nóng chảy gia tăng đó buộc các tấm của chúng ta tách ra ở một số nơi ... và đẩy họ lại với nhau trong những người khác! Khi các tấm tách ra ... một "Rift phân kỳ" phát triển! Núi lửa phun trào xảy ra ở đây! Khi mảng kiến tạo lục địa va chạm... Núi mọc lên ... và Lục địa tham gia! Kết quả động đất khủng khiếp! Khi các mảng đại dương hội tụ ... Núi lửa bùng nổ ... và Sóng thần chết đuối hàng ngàn người !!

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the following questions from (71) to (80)

The Moon has been worshipped by primitive peoples and has inspired humans to create everything from lunar calendars to love sonnets, but what do we really know about it? The most accepted theory about the origin of the Moon is that it was formed of the debris from a massive collision with the young Earth about 4.6 billion years ago. A huge body, perhaps the size of Mars, struck the Earth, throwing out an immense amount of debris that coalesced and cooled in orbit around the Earth.

The development of Earth is inextricably linked to the moon; the Moon's gravitational influence upon the Earth is the primary cause of ocean tides. In fact, the Moon has more than twice the effect upon the tides than does the Sun. The Moon makes one rotation and completes a revolution around the Earth every 27 days, 7 hours, and 43 minutes. This synchronous rotation is caused by an uneven distribution of mass in the Moon (essentially, it is heavier on one side than the other) and has allowed the Earth's gravity to keep one side of the Moon permanently facing Earth. It is an average distance from Earth of 384,403 km.

The Moon has no atmosphere; without an atmosphere, the Moon has nothing to protect it from meteorite impacts, and thus the surface of the Moon is covered with impact craters, both large and small. The Moon also has no active tectonic or volcanic activity, so the erosive effects of atmospheric weathering, tectonic shifts, and volcanic upheavals that tend to erase and reform the Earth's surface features are not at work on the Moon. In fact, even tiny surface features such as the footprint left by an astronaut in the lunar soil are likely to last for millions of years, unless obliterated by a chance meteorite strike. The surface gravity of the Moon is about one-sixth that of the Earth's. Therefore, a man weighing 82 kilograms on Earth would only weigh 14 kilograms on the Moon.

The geographical features of the Earth most like that of the Moon are, in fact, places such as the Hawaiian volcanic craters and the huge meteor crater in Arizona. The climate of the Moon is very unlike either Hawaii or Arizona, however; in fact the temperature on the Moon ranges between 123 degrees C. to - 233 degrees C.

The word "debris" is closest in meaning to

A. satellites

B. rubbish

C. moons

D. earth

The development of Earth is inextricably linked to the moon; the Moon's gravitational influence upon the Earth is the primary cause of ocean tides. In fact, the Moon has more than twice the effect upon the tides than does the Sun. The Moon makes one rotation and completes a revolution around the Earth every 27 days, 7 hours, and 43 minutes. This synchronous rotation is caused by an uneven distribution of mass in the Moon (essentially, it is heavier on one side than the other) and has allowed the Earth's gravity to keep one side of the Moon permanently facing Earth. It is an average distance from Earth of 384,403 km.

The Moon has no atmosphere; without an atmosphere, the Moon has nothing to protect it from meteorite impacts, and thus the surface of the Moon is covered with impact craters, both large and small. The Moon also has no active tectonic or volcanic activity, so the erosive effects of atmospheric weathering, tectonic shifts, and volcanic upheavals that tend to erase and reform the Earth's surface features are not at work on the Moon. In fact, even tiny surface features such as the footprint left by an astronaut in the lunar soil are likely to last for millions of years, unless obliterated by a chance meteorite strike. The surface gravity of the Moon is about one-sixth that of the Earth's. Therefore, a man weighing 82 kilograms on Earth would only weigh 14 kilograms on the Moon.

The geographical features of the Earth most like that of the Moon are, in fact, places such as the Hawaiian volcanic craters and the huge meteor crater in Arizona. The climate of the Moon is very unlike either Hawaii or Arizona, however; in fact the temperature on the Moon ranges between 123 degrees C. to - 233 degrees C.

What is the passage primarily about?

A. what we know about the Moon and its differences to Earth

B. the origin of the Moon

C. the Moon's effect upon the Earth

D. a comparison of the Moon and the Earth
