  • 2. 

    Air selalu tersedia dibumi karena adanya siklus

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given statement is true because air is always available on Earth due to the existence of the water cycle. The water cycle is a continuous process in which water evaporates from the Earth's surface, forms clouds, and then falls back to the Earth as precipitation. This cycle ensures that there is a constant supply of water vapor in the atmosphere, which eventually condenses and becomes available as air. Therefore, air is always present on Earth thanks to the water cycle.

    Rate this question:

  • 3. 

    Perputaraan air terus menerus dari bumi ke atmosfer kembali lagi ke bumi disebut

    • Siklus udara

    • Siklus uap

    • Siklus air

    • Siklus energi

    Correct Answer
    A. Siklus air
    Explanation
    The correct answer is "siklus air". This term refers to the continuous movement of water from the Earth's surface to the atmosphere and back again. It involves processes such as evaporation, condensation, precipitation, and runoff. The water cycle plays a crucial role in maintaining the Earth's climate and supporting various ecosystems.

    Rate this question:

  • 4. 

    Air hujan yang jatuh ke tanah akan menjadi air tanah

    • True

    • False

    Correct Answer
    A. True
    Explanation
    When rainwater falls onto the ground, it can infiltrate into the soil and become groundwater. This process is known as recharge, where the water percolates through the soil and accumulates in underground aquifers. Therefore, it is true that rainwater that falls onto the ground can become groundwater.

    Rate this question:

  • 5. 

    Chlorine dapat membunuh kuman berbahaya yang terdapat pada air

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Chlorine is a powerful disinfectant that is commonly used to kill harmful bacteria and microorganisms in water. It is added to water supplies and swimming pools to ensure that the water is safe for consumption and swimming. Chlorine works by attacking and destroying the cell walls and enzymes of bacteria, effectively killing them. Therefore, it is true that chlorine can kill dangerous germs that may be present in water.

    Rate this question:

  • 6. 

    Proses penguapan, pengendapan, dan pengembunan bagian dari siklus air

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given statement is true. The process of evaporation, precipitation, and condensation are all part of the water cycle. Evaporation occurs when water changes from a liquid to a gas and rises into the atmosphere. Precipitation happens when water vapor condenses into liquid or solid form and falls back to the Earth's surface as rain, snow, sleet, or hail. Condensation is the process of water vapor cooling and changing back into liquid form. These three processes are interconnected and essential for the continuous circulation of water on Earth.

    Rate this question:

  • 7. 

    Reboisasi dapat mencegah bencana kekeringan

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Reboisasi dapat mencegah bencana kekeringan karena pohon-pohon yang ditanam dalam reboisasi dapat menyerap air dari tanah dan mengurangi penguapan air melalui proses transpirasi. Selain itu, akar pohon juga dapat menahan air hujan dan mencegah erosi tanah. Dengan demikian, reboisasi dapat meningkatkan ketersediaan air tanah dan mengurangi risiko kekeringan.

    Rate this question:

  • 8. 

    Sebagian besar air yang ada di bumi berupa air asin

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement says that most of the water on Earth is salty. This is true because about 97% of the Earth's water is found in the oceans and seas, which are saline or salty. Only about 3% of the Earth's water is freshwater, found in lakes, rivers, and underground sources. Therefore, the correct answer is true.

    Rate this question:

  • 9. 

    Cara mencegah kekeringan air , KECUALI

    • Membuat daerah resapan air

    • Menanam pohon

    • Membuang sampah ke sungai

    • Menghemat air

    Correct Answer
    A. Membuang sampah ke sungai
    Explanation
    The correct answer is "Membuang sampah ke sungai" because throwing trash into rivers can lead to water pollution and blockage of water flow, which can exacerbate water scarcity issues. It is important to properly dispose of waste and not contribute to the contamination of water sources.

    Rate this question:

  • 10. 

    Jika daerah resapan air berkurang maka cadangan air semakin bertambah

    • True

    • False

    Correct Answer
    A. False
    Explanation
    If the area of water infiltration decreases, it means that the water reserve is also decreasing, not increasing. Therefore, the given statement is false.

    Rate this question:

  • 11. 

    Meminum air yang mengandung kuman dapat menyebabkan penyakit diare, kolera dan disentri

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Drinking water that contains germs can indeed lead to diseases such as diarrhea, cholera, and dysentery. These diseases are often caused by ingesting contaminated water that is contaminated with bacteria, viruses, or parasites. When these harmful microorganisms enter the body through the consumption of contaminated water, they can cause various gastrointestinal symptoms and lead to severe illness. Therefore, it is important to ensure that the water we drink is clean and free from any harmful germs to prevent these diseases.

    Rate this question:

  • 12. 

    Syarat fisik air, kecuali

    • Tidak keruh

    • Tidak berwarna

    • Tidak mengandung kuman penyakit

    • Tidak berbau

    Correct Answer
    A. Tidak mengandung kuman penyakit
    Explanation
    The given answer, "Tidak mengandung kuman penyakit" (Does not contain disease-causing germs), is the correct answer because the other options describe physical characteristics of water. The water being clear, colorless, and odorless are all physical properties of water, while not containing disease-causing germs is a requirement for water to be safe for consumption. Therefore, the answer "Tidak mengandung kuman penyakit" is the only option that does not describe a physical characteristic of water.

    Rate this question:

  • 13. 

    Keadaan udara yang tidak dapat menampung uap air disebut evaporasi

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is incorrect. The correct term for air that cannot hold any more water vapor is "saturation." Saturation occurs when the air is already holding the maximum amount of water vapor it can at a given temperature and pressure. Evaporation, on the other hand, refers to the process of liquid water turning into water vapor and entering the air.

    Rate this question:

  • 14. 

    Syarat Kimiawi air bersih

    • Tidak meninggalkan endapan

    • Tidak mengandung kuman penyakit

    • Ph 6,5 - 9,2

    • Suhu 10 0 - 250

    Correct Answer
    A. Ph 6,5 - 9,2
    Explanation
    The correct answer is "Ph 6,5 - 9,2". This range of pH indicates that clean water should have a slightly acidic to slightly alkaline nature. Water with a pH below 6.5 may be too acidic and can be corrosive, while water with a pH above 9.2 may be too alkaline and can have a bitter taste. Maintaining the pH within this range ensures that the water is safe for consumption and does not cause any health issues.

    Rate this question:

  • 15. 

    Ketika suhu udara naik maka uap air akan menjadi awan

    • True

    • False

    Correct Answer
    A. False
    Explanation
    When the air temperature rises, it causes the water vapor to evaporate and form clouds. Therefore, the correct answer should be "True" instead of "False."
