Most people think that dust is very harmful to us. But this is not true. Dust is, in fact, very useful, and therefore, it is essential to know what dust is and how it is formed. Every solid substance is composed of very small particles. When these small particles of matters are scattered, they become dust particles. Forexample, if we go on breaking a brick or a stone into small pieces, it will turn into small particles. These particles get mixed with air and they are called dust particles. The air carries dust particles from one place to another. There are different ways by which dust is formed. When solid substance break, dust is formed. Smoke generated by the burning of coal, wood, petrol, etc., also produces dust. Dust particles also come from death plants, sea salt, desert, volcanic sand, etc. The particles of the earth’s surface also fly in the air. In the form of dust. The biggest use of the dust particles is that they help in the formation of the rain. The water vapors in the clouds condenses on the dust particles in the form of water –drops. These drops fall on the earth as rains. The absence of dust particles can delay the rain. Likewise, mist, fog, etc, are also formed due to the presence of dust particles.. How can dust move from one place to another?

Question

Jawaban yang benar adalah "Dust particles get mixed with air so the air carries dust particles from one place to another."

Soal menanyakan bagaimana debu bisa berpindah dari satu tempat ke tempat lain.

Pada teksnya tertera "For example, if we go on breaking a brick or a stone into small pieces, it will turn into small particles. These particles get mixed with air and they are called dust particles. The air carries dust particles from one place to another". (Misalnya, jika kita terus memecahkan batu bata atau batu menjadi potongan-potongan kecil, itu akan berubah menjadi partikel-partikel kecil. Partikel-partikel ini bercampur dengan udara dan mereka disebut partikel debu. Udara membawa partikel-partikel debu dari satu tempat ke tempat lain.)

Dari kutipan tersebut, dapat disimpulkan bahwa partikel-partikel debu bercampur dengan udara, jadi udara membawa partikel-partikel debu dari satu tempat ke tempat lain.

Jadi, jawaban yang benar adalah "Dust particles get mixed with air so the air carries dust particles from one place to another."
