Berikut yang bukan merupakan penyebab dari global warming adalah...
Correct Answer
C. Pemakaian sepeda secara serentak
Explanation
The use of bicycles simultaneously does not contribute to global warming as it does not release greenhouse gases or contribute to the emission of pollutants that cause the greenhouse effect. In fact, using bicycles instead of motor vehicles can help reduce carbon emissions and mitigate the effects of global warming.

Correct Answer
C. Menghangatkan suhu bumi sehingga nyamban untuk ditinggali
Explanation
The correct answer is "Menghangatkan suhu bumi sehingga nyaman untuk ditinggali." The greenhouse effect is necessary for life on Earth because it helps to warm the planet's surface to a habitable temperature. Without the greenhouse effect, the Earth would be too cold to support life as we know it. The greenhouse gases in the atmosphere, such as carbon dioxide and methane, trap heat from the sun and prevent it from escaping back into space, thus keeping the Earth warm.

Komponen pada penggunaan alat transportasi yang mengakibatkan suhu udara mengalami peningkatan adalah...
Correct Answer
A. Emisi CO2 dari bahan bakar transportasi
Explanation
Emisi CO2 dari bahan bakar transportasi dapat menyebabkan peningkatan suhu udara. Ketika bahan bakar seperti bensin atau diesel dibakar dalam mesin kendaraan, CO2 dilepaskan ke atmosfer. CO2 adalah gas rumah kaca yang berperan dalam efek rumah kaca, yang menyebabkan peningkatan suhu global. Jadi, emisi CO2 dari bahan bakar transportasi dapat menyebabkan peningkatan suhu udara.

Correct Answer
E. Meningkatnya suhu rata-rata bumi
Explanation
The greenhouse effect is a process where heat is trapped in the Earth's atmosphere, leading to an increase in average global temperatures. This is caused by the accumulation of greenhouse gases such as carbon dioxide and methane, which trap heat from the sun and prevent it from escaping into space. As a result, the Earth's temperature rises, leading to an increase in the average global temperature. Therefore, the correct answer is "Meningkatnya suhu rata-rata bumi" which means "Increase in average global temperature".

Ciri-ciri terjadinya pemanasan global adalah...
Correct Answer
B. Nyamuk terbang ke dataran tinggi
Explanation
The correct answer is "Nyamuk terbang ke dataran tinggi." This is because one of the characteristics of global warming is the expansion of the habitat range for certain species, including mosquitoes. As temperatures rise, mosquitoes are able to survive and reproduce in higher altitudes that were previously too cold for them. This can lead to the spread of diseases carried by mosquitoes to new areas.

Correct Answer
B. Reuse
Explanation
The correct answer is "Reuse". In the given scenario, Taeyang is writing his project proposal on his father's used paper. This aligns with the principle of reusing, as he is utilizing a resource that would have otherwise been discarded. Reusing items helps to reduce waste and conserve resources by giving them a second life before they are eventually recycled or disposed of.

Upaya pemerintah dalam menangani pemanasan global adalah ...
Correct Answer
D. Penanaman Seribu Pohon
Explanation
The correct answer is "Penanaman Seribu Pohon". This answer suggests that the government's effort in addressing global warming is through tree planting. Planting trees is a common strategy used to combat global warming as trees absorb carbon dioxide, a greenhouse gas that contributes to global warming, and release oxygen into the atmosphere. By planting a thousand trees, the government aims to reduce the amount of carbon dioxide in the air and mitigate the effects of global warming.

Keuntungan penghijauan di kota-kota antara lain karena tanaman dapat ...
Correct Answer
A. Mengubah CO2 dan udara menjadi O2
Explanation
The correct answer states that the benefit of greening in cities is that plants can convert CO2 and air into O2. This means that through the process of photosynthesis, plants take in CO2 from the air and release O2, which helps to increase the oxygen levels in the environment.
9.
Lapisan atmosfir yang melindungi bumi dari tembusnya sinar ultraviolet dari matahari ialah…
Correct Answer
C. Ozon
Explanation
The correct answer is ozone. The ozone layer is a protective layer in the Earth's atmosphere that absorbs most of the Sun's ultraviolet (UV) radiation. This layer acts as a shield, preventing harmful UV rays from reaching the Earth's surface and protecting living organisms from the damaging effects of UV radiation.
10.
Radiasi panas matahari yang terkurung dalam atmosfir bumi, serta meningkatnya panas oleh pengikatan CO2 dikenal sebagai …
Correct Answer
C. Efek rumah kaca
Explanation
The correct answer is "efek rumah kaca". This refers to the phenomenon where heat from the sun is trapped in the Earth's atmosphere, causing an increase in temperature due to the increased concentration of CO2. This is commonly known as the greenhouse effect, as it is similar to how a greenhouse traps heat.
