Proses cuaca terjadi pada lapisan...
- A.
Termosfer
- B.
Stratosfer
- C.
Mesosfer
- D.
Troposfer
Correct Answer
D. TroposferExplanation
The correct answer is troposfer. The troposfer is the lowest layer of the Earth's atmosphere, extending from the surface up to about 10-15 kilometers. It is where most weather phenomena occur, including clouds, precipitation, and storms. The troposfer is characterized by vertical mixing of air, which allows for the transport of heat, moisture, and pollutants. It is also where temperature generally decreases with increasing altitude.Rate this question:

Lapisan ozon terdapat pada lapisan...
- A.
Troposfer
- B.
Termosfer
- C.
Stratosfer
- D.
Mesosfer
Correct Answer
C. StratosferExplanation
The correct answer is stratosfer. The ozone layer is found in the stratosphere, which is the second layer of the Earth's atmosphere. The ozone layer plays a crucial role in protecting life on Earth by absorbing the majority of the sun's ultraviolet (UV) radiation. This absorption prevents most of the harmful UV rays from reaching the Earth's surface, which can cause skin cancer, cataracts, and other harmful effects on both humans and the environment.Rate this question:

Dibawah ini yang BUKAN merupakan sifat-sifat atmosfer yaitu....
- A.
Mempunyai berat sehingga dapat menekan
- B.
Menjaga temperatur bumi sehingga tetap hangat
- C.
Tidak berbau, tidak berwarna dan tidak dapat dirasakan
- D.
Elastis dan dinamis sehingga dapat mengembang dan mengerut
Correct Answer
B. Menjaga temperatur bumi sehingga tetap hangatExplanation
The correct answer is "menjaga temperatur bumi sehingga tetap hangat". This is because maintaining the temperature of the Earth is not a characteristic of the atmosphere. The atmosphere is responsible for many important functions such as providing oxygen, protecting us from harmful radiation, and regulating the climate, but it does not actively regulate the temperature of the Earth to keep it warm.Rate this question:

Keadaan udara pada suatu saat di suatu tempat disebut….
- A.
Cuaca
- B.
Iklim
- C.
Suhu
- D.
Temperatur
Correct Answer
A. CuacaExplanation
Cuaca refers to the state of the atmosphere at a specific time and place, including factors such as temperature, humidity, wind speed, and precipitation. It is a short-term condition that can change throughout the day or week. In contrast, iklim refers to the long-term weather patterns and averages in a particular region over a period of time, usually 30 years or more. Suhu and temperatur both mean temperature, which is a specific measurement of the warmth or coldness of the air or a substance. Therefore, the correct answer is cuaca.Rate this question:

Unsur-unsur cuaca antara lain...
- A.
Iklim, suhu udara, dan musim
- B.
Temperatur udara, tekanan udara, dan angin
- C.
Kelembaban udara, awan dan iklim
- D.
Awan, curah hujan dan suhu udara
Correct Answer
B. Temperatur udara, tekanan udara, dan anginExplanation
The correct answer is "temperatur udara, tekanan udara, dan angin" (air temperature, air pressure, and wind). These elements are important factors in determining weather conditions. Air temperature refers to the measure of how hot or cold the air is, while air pressure is the force exerted by the atmosphere on a given area. Wind is the movement of air caused by differences in air pressure. These three elements play a crucial role in understanding and predicting weather patterns.Rate this question:

Lapisan atmosfer dengan ketinggian 0-8 km dari permukaan bumi disebut....
- A.
Stratosfer
- B.
Mesosfer
- C.
Troposfer
- D.
Termosfer
Correct Answer
C. TroposferExplanation
The correct answer is troposfer. The troposphere is the lowest layer of the Earth's atmosphere, extending from the surface up to about 8 kilometers. It is where weather phenomena occur and where most of the Earth's air mass is located. The other options, stratosphere, mesosphere, and thermosphere, are higher layers of the atmosphere.Rate this question:

Satu unsur cuaca yang bisa kita amati dengan dengan menggunakan kincir angin adalah...
- A.
Awan
- B.
Hujan
- C.
Kelembaban udara
- D.
Angin
Correct Answer
D. AnginExplanation
One weather element that can be observed using a windmill is wind. Windmills are designed to harness the power of wind and convert it into mechanical energy. By observing the movement and speed of the windmill blades, we can determine the presence and strength of the wind.Rate this question:

Di daerah kita sering terjadi hujan pada sore hari setelah panas yang terik pada siang hari, hujan semacam ini disebut hujan…
- A.
Zenithal
- B.
Siklon
- C.
Orografis
- D.
Frontal
Correct Answer
D. FrontalExplanation
The correct answer is frontal. In the given question, it is mentioned that in our area, it often rains in the afternoon after hot weather during the day. This type of rain is called frontal rain. Frontal rain occurs when a warm air mass and a cold air mass meet, causing the warm air to rise and cool, leading to condensation and precipitation. This weather pattern is commonly observed in areas where there are frequent changes in air masses, such as during the transition from a hot day to a cooler afternoon.Rate this question:

Angin adalah....
- A.
Udara yang bergerak
- B.
Awan yang mengandung air
- C.
Awan yang bergerak
- D.
Udara yang mengisi ruang
Correct Answer
A. Udara yang bergerakExplanation
Angin adalah udara yang bergerak. Angin terjadi ketika udara bergerak dari daerah dengan tekanan tinggi ke daerah dengan tekanan rendah. Pergerakan udara ini dapat disebabkan oleh perbedaan suhu, tekanan, atau kelembaban di berbagai daerah. Angin dapat bergerak dengan kecepatan yang bervariasi, dari angin lembut hingga angin kencang. Angin memiliki peran penting dalam mengatur iklim dan cuaca di berbagai wilayah di seluruh dunia.Rate this question:

- A.
Angin
- B.
Awan
- C.
Udara
- D.
Kilat
Correct Answer
B. AwanExplanation
Perairan mengalami penguapan karena pemanasan sinar matahari. Ketika suhu perairan mencapai titik tertentu, air akan berubah menjadi uap air dan naik ke atmosfer. Di atmosfer, uap air akan mendingin dan membentuk partikel-partikel kecil yang disebut awan. Oleh karena itu, awan adalah hasil dari penguapan perairan yang terjadi akibat pemanasan sinar matahari.Rate this question:
