Proses terbentuknya Salju | by Hiba
Summary
TLDRIn this educational video, a student from Accounting Class 11 at SMK Negeri 2 Pekalongan, Indonesia, explains the process of snow formation. Starting with evaporation of seawater, the process involves water vapor condensing in the atmosphere to form clouds. Subsequently, the water vapor crystallizes into ice, forming snowflakes. If the temperature is above 0°C, it rains, but below 0°C, the ice crystals mix with nucleators and freeze, resulting in snowfall. The explanation is delivered in Bahasa Indonesia, adding a cultural touch to the scientific lesson.
Takeaways
- 🌊 The process of snow formation begins with evaporation of seawater.
- 🌬️ Water vapor rises into the atmosphere and cools down.
- ❄️ As the water vapor cools, it freezes into small particles forming clouds.
- 🔄 The next step is sublimation, where water vapor turns directly into ice crystals without becoming liquid first.
- 🌞 When these ice crystals fall to the earth and pass through sunlight, they may melt.
- 🌧️ If the temperature is above 0°C, the ice crystals will melt and cause rain.
- ❄️ If the temperature is below 0°C, the ice crystals will mix with impurities, forming snow.
- 🌡️ The presence of impurities, or 'nucleators', can cause the ice crystals to freeze more quickly.
- 🌍 Snow falls to the earth in the form of very soft particles.
- 📚 The explanation is part of an accounting class at SMK Negeri 2 Pekalongan, Indonesia, and is delivered in Bahasa Indonesia.
Q & A
What is the topic of the explanation provided in the script?
-The topic of the explanation is the process of snow formation.
What is the first process mentioned in the script for the formation of snow?
-The first process mentioned is evaporation, where water from the sea evaporates into the air.
How does the water from evaporation contribute to the formation of snow?
-The water that evaporates forms tiny particles that create clouds in the atmosphere.
What is the term used for the process where water vapor turns into a liquid or solid state?
-The term used for this process is condensation.
What happens to the water vapor in the clouds according to the script?
-The water vapor in the clouds forms crystals or pure water.
What is the role of the sun's rays in the process described in the script?
-The sun's rays cause the crystals to melt if they pass through them.
What is the condition for rain to occur instead of snow as described in the script?
-Rain occurs when the temperature is above 0°C.
What happens to the particles when the temperature is below 0°C according to the script?
-When the temperature is below 0°C, the particles mix with nucleators.
What is a nucleator in the context of snow formation?
-A nucleator is a substance that helps water molecules to clump together and freeze more quickly.
How does the mixing of water with nucleators contribute to snow formation?
-The mixing of water with nucleators leads to the formation of snowflakes that are more likely to fall to the ground as snow.
What is the final outcome of the process described in the script?
-The final outcome is the formation of snow, which falls to the ground in soft particles.
Outlines
🌨️ Snow Formation Process
The speaker introduces themselves as a student from Accounting Class 11 at SMK Negeri 2 Pekalongan, with a presence number of 15. They discuss the process of snow formation in Indonesia. The process begins with evaporation where seawater evaporates into the atmosphere, forming small particles that create clouds. Next, the water vapor undergoes condensation to form ice crystals. When these ice crystals fall to the ground and pass through sunlight, they may melt and form rain if the temperature is above 0°C. If the temperature is below 0°C, the ice crystals mix with a nucleus, possibly influenced by the local conditions of Wonorejo Timur, and combine with the 0°C water to freeze more quickly. This results in snowflakes that fall to the ground in a soft particle form. The explanation concludes with a polite request for feedback and a closing greeting.

Halo assalamualaikum warahmatullahi
wabarakatuh perkenalkan nama saya
Jelaskan isi dari kelas 11 akunting satu
dari sekolah SMK Negeri 2 Pekalongan
nomor presensi 15 pada mapel bahasa
Indonesia ini saya akan membahas tentang
teks eksplanasi terjadinya salju untuk
prosesnya Mari kita disini untuk proses
pembentukan salju yang pertama yaitu
proses evaporasi yang dimulai dengan
menguapnya air laut ke udara melekat
asmosfer melalui udara dan di atmosfer
air tersebut membeku lalu turun menjadi
partikel-partikel kecil membentuk awan
lalu proses selanjutnya Yaitu konsumsi
yaitu kondensasi itu
Ibu air tadi yang membentuk Awan mau
saja terbentuk kristal atau air murni
yang kemudian apabila turun ke bumi
melewati cahaya matahari lalu partikel
kristal tersebut akan mengalah dan
terjadi hujan apabila suhunya di atas 0°
apabila suhu dibawah minus nol derajat
maka partikel tersebut akan bercampur
dengan nukleator lalu tersebut juga
dengan air murni yang suhunya itu 0°
Celcius atau mungkin juga Wonorejo Timur
pada saat air tersebut dengan nukleator
kota di sini atau bercampur menjadi satu
partikel yang membuat air murni menjadi
lebih cepat
Hai membeku maka terjadilah atau
terbentuklah salju maka akan turun ke
bumi salju akan turun ke bumi dalam
bentuk partikel-partikel yang sangat
lembut
Hai Sekian dari saya penjelasan mengenai
pembentukan salju perawinya mohon maaf
Assalamu'alaikum warahmatullahi
wabarakatuh
