Every single rock on the surface of the Earth-whether it is gravestone, a piece of solidified lava from a volcano or a boulder that has broken from a cliff or mountain-is slowly being broken down. This breaking down of rocks at or near the Earth’s surface is called weathering. The word is used because the weather is mainly responsible. Weathering turns solid rock into soft materials that may eventually form soil. Air and water are the cause of most weathering. Sometimes they change the chemical in the rocks, and sometimes they just break apart the rock physically. If water seeps into the cracks in the rocks, for example, it may later freeze if the temperature falls below 0 degrees Celsius. As the water turns to ice, it expands, pushing against the sides of the rock with a pressure believe to be as much as 2,100 kilograms per square centimetre. This forces the cracks open. Repeated freezing and thawing causes the fragments to break away from the original rock, these may slide down a cliff or mountain and form a sloping mass of fragments at the bottom, called scree. According to the text,?
- there are two kinds of rock, gravestone and a boulder
- cracks in the rocks will turn water into ice at the temperature below 0 degrees Celsius
- a cliff or mountain may slide down because of the water in the rocks
- chemical in the rocks causes weathering in every single rock-
- soft materials will turn to solidified lava through weathering
Jawaban yang benar adalah: C. a cliff or mountain may slide down because of the water in the rocks.

Pembahasan dan Penjelasan
Menurut saya jawaban A. there are two kinds of rock, gravestone and a boulder adalah jawaban yang kurang tepat, karena sudah terlihat jelas antara pertanyaan dan jawaban tidak nyambung sama sekali.
Menurut saya jawaban B. cracks in the rocks will turn water into ice at the temperature below 0 degrees Celsius adalah jawaban salah, karena jawaban tersebut lebih tepat kalau dipakai untuk pertanyaan lain.
Menurut saya jawaban C. a cliff or mountain may slide down because of the water in the rocks adalah jawaban yang paling benar, bisa dibuktikan dari buku bacaan dan informasi yang ada di google.
Menurut saya jawaban D. chemical in the rocks causes weathering in every single rock- adalah jawaban salah, karena jawaban tersebut sudah melenceng dari apa yang ditanyakan.
Menurut saya jawaban E. soft materials will turn to solidified lava through weathering adalah jawaban salah, karena setelah saya coba cari di google, jawaban ini lebih cocok untuk pertanyaan lain.
Kesimpulan
Dari penjelasan dan pembahasan serta pilihan diatas, saya bisa menyimpulkan bahwa jawaban yang paling benar adalah C. a cliff or mountain may slide down because of the water in the rocks.
