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.

Jawaban yang tepat adalah B.

Pada soal ditanyakan "What causes the Earth to become warmer?" atau apa yang menyebabkan bumi menjadi lebih panas?

Pada paragraf 2 terdapat kalimat beikut :
The Earth’s atmosphere allows most of the Sun’s rays to pass through it to heat the Earth’s surface.
(Atmosfer bumi memungkinkan sebagian besar sinar matahari melewatinya untuk memanaskan permukaan bumi.)

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.
(Bumi memantulkan banyak energi panas kembali ke atmosfer, tetapi banyak dari radiasi yang dipantulkan ini tidak dapat lepas karena gas-gas seperti karbon dioksida menyerapnya.)

They grow warm and send heat radiation back to Earth. This is the greenhouse effect. 
(Mereka menghangat dan mengirim radiasi panas kembali ke Bumi. Ini adalah efek rumah kaca.)

Maka, dapat diketahui yang membuat bumi menjadi lebih hangat adalah radiasi panas yang tidak dikirim ke atmosfer, melainkan dikirim kembali kebumi karena terserap oleh  karbon dioksida yang membuat hangat atau The heat radiation sent back to Earth by gases that grow warm. (B)
