One way to stop soil erosion on flat open ground is to grow small plants such as grasses. These plants are called cover crops. Their roots hold the soil tightly together. Thus rainwater cannot wash away the soil. When trees and tall bushes are planted at the edges of an open field, soil erosion by strong winds cannot take place. The trees and bushes protect the open land from the winds. They act as a very big wall.
Soil erosion on slopes can be stopped in a number of ways. One way is to cut a slope into “steps” called terraces. Water carrying soil then cannot run straight down the slope. It has to run down the terraces. This slows down the flow of the water. Most of the soil in the water is left behind on the terraces. Water can carry away the soil only if it is flowing fast. In this way, the soil washed away from the upper part of the slope will be left on the terraces. The edges of the terraces can be raised. The raised edges are called bunds. These will hold back the rainwater and the soil which it carries.
Sometimes trees are planted in narrow steps cut into the hill slopes. These steps, which are called contour, slow down the flowing rainwater. Cover crops growing on contour or the slopes between terraces also help to stop soil erosion
The topic of the text is about ___ .
a. small plants and bushes to prevent soil erosion
b. some ways to stop soil from erosion
c. some benefit of planting trees in the hill slopes
d. constructing terraces to stop soil erosion
e. rainwater as the cause of soil erosion

TEKS 1
Salah satu cara untuk menghentikan erosi tanah di tanah terbuka datar adalah untuk tumbuh tanaman kecil seperti rumput. Tanaman ini disebut tanaman penutup. Akarnya menahan tanah erat. Dengan demikian air hujan tidak bisa membasuh tanah. Ketika pohon dan semak-semak tinggi ditanam di tepi lapangan terbuka, erosi tanah oleh angin yang kuat tidak dapat berlangsung. Pohon-pohon dan semak-semak melindungi lahan terbuka dari angin. Mereka bertindak sebagai dinding yang sangat besar.
Erosi tanah di lereng dapat berhenti di sejumlah cara. Salah satunya adalah dengan memotong lereng menjadi "langkah" disebut teras. Air membawa tanah maka tidak bisa berjalan lurus menuruni lereng. Hal ini untuk lari ke teras. Hal ini memperlambat aliran air. Sebagian besar tanah di dalam air yang tertinggal di teras. Air dapat membawa pergi tanah hanya jika mengalir cepat. Dengan cara ini, tanah hanyut dari bagian atas lereng akan ditinggalkan di teras. Tepi teras dapat ditingkatkan. Tepi mengangkat yang disebut bunds. Ini akan menahan air hujan dan tanah yang dibawanya.
Kadang-kadang pohon ditanam dalam langkah-langkah yang sempit memotong ke lereng bukit. Langkah-langkah ini, yang disebut kontur, memperlambat air hujan mengalir. Tanaman penutup yang tumbuh di kontur atau lereng antara teras juga membantu untuk menghentikan erosi tanah
Topik teks adalah tentang ___.
