A landslide is the movement of rock, earth or debris down a sloped section of land. Landslides are caused by rain, earthquakes, volcanoes or other factory that make the slopes unstable. Landslides have three major causes : geology, morphology and human activities. Geology refers to characteristics of the materials itself. The earth or rock might be weak or fractured, or different layers may have different strengths and stiffness. Morphology refers to the structure of the land. For example, slopes that lose their vegetation to fire or drought are more vulnerable to landslides. Human activitiy, such as agriculture and construction, can increase the risk of a landslide. Irrigation, deforestation and excavation can read destabilize or weaken a slope. A landslide can involve rock, soil, vegetation, water or some combination of all these. A landslide caused by a volcanos can also contain hot volcanic ash and lava from the eruption. A landslide high in the mountains may have snow and snowmelt. Adopted from: https://wws.nationalgeographic.org/encyclopedia/ landslide/ (30th November 2018) Why do the players of soil have different strength and stiffness?

Why do the players of soil have different strength and stiffness?

  1. They contain different materials.

  2. They receive different pressure.

  3. They are located in different height.

  4. They are linfluenced by the vegetation.

Pembahasan

Berdasarkan teks bacaan di atas, kalimat “geology refers to characteristics of the material itself. The earth or rock might be weak or fractured, or different layers may have different strengts and stiffness” menjelaskan bahwa geology yang merujuk pada karakteristik material dalam tanah. Bumi atau batu dapat menjadi lemah dan patah, atau perbedaan lapisan dapat menyebabkan perbedaan kekuatan dan kekakuan lapisan. Maka dapat dismpulkan bahwa perbedaan tersebut disebabkan oleh “they contain different materials”.
