Greenhouse Effect

When fossil fuels, or other fuels, such as wood or peat, which contain carbon are burned, carbon dioxide is released into the atmosphere. Vehicles also give out, and so add, carbon dioxide to the atmosphere.

The Earth’s atmosphere allows most of the Sun’s rays to pass through it to heat the Earth’s surface. The Earth reflects much of the heat energy back into the atmosphere, but much of this reflected radiation cannot escape because gases such as carbon dioxide absorb it. They grow warm and send heat radiation back to Earth. This is the greenhouse effect. Many scientists think that the greenhouse effect may change the climate, over the next 100 years or so. One consequence of so-called “global warming” resulting from the greenhouse effect could be melting of the polar ice. This in turn, could lead to a rise in sea level which could flood large areas of highly populated coastal land.

If carbon dioxide proves to be harmful as thought in order to reduce carbon dioxide levels we need to reduce the amounts of carbon-rich fuels burned.

20. What will happen if the sea level rises?
a. The polar ice will melt and make the sea get cooler.
b. Some large areas of coastal land will be inundated.

d. The surface of Earth will be flooded with water.

H. R. · Accepted Answer

Jawaban yang benar adalah "b. Some large areas of coastal land will be inundated." (Beberapa wilayah pesisir yang luas akan tergenang.)

Dalam soal ini kamu diminta untuk memilih jawaban yang tepat berdasarkan teks yang tersedia.

Soal:

"What will happen if the sea level rises?" (Apa yang akan terjadi jika permukaan air laut naik?)

Jawaban dapat diperoleh dari:

"This in turn, could lead to a rise in sea level which could flood large areas of highly populated coastal land." (Hal ini, dapat menyebabkan kenaikan permukaan laut yang dapat membanjiri sebagian besar wilayah pesisir yang berpenduduk padat.)

Dari kutipan tersebut dapat disimpulkan bahwa yang akan terjadi jika permukaan air laut naik adalah sebagian besar wilayah pesisir yang berpenduduk padat akan tergenang/terkena banjir rob (air laut).

Oleh karena itu, jawaban yang benar adalah "b. Some large areas of coastal land will be inundated." (Beberapa wilayah pesisir yang luas akan tergenang.)
