V. Read the passage and choose the correct answer to each of the questions. (Đọc đoạn văn và chọn 
đáp án đúng để hoàn thành các câu hỏi.)
 Earth is a unique planet in our solar system. Unlike the hot, rocky planets closer to the Sun or 
the cold, gas giants further out, Earth has the right conditions to support the life as we know it. Our 
atmosphere, a layer of gases surrounding the planet, acts like a giant blanket, trapping heat from the 
Sun and keeping the temperature within a range suitable for liquid water to exist. Water is essential for 
life, and Earth has a vast amount of it in liquid form on its surface – oceans, lakes, and rivers.
 Earth is also the only planet known to have plate tectonics. This process involves giants slabs of 
rock, called tectonic plates, slowly moving around the planet’s surface. The movement of these plates 
creates mountains, volcanoes, and earthquakes, but it also plays a crucial role in recycling nutrients and 
maintaining a stable climate.
