1
Unlike every other planet in our solar system, Earth's surface is 70 % liquid water, which while useful for life, is also kind of weird,
2
because everything we know about how and when our planet formed says Earth's surface should be bone dry.
3
The story goes like this.
4
Our solar system formed from the collapse of a large cloud of dust and gas.
5
The dense blob of gas at the center ignited to form the sun, which as a young unstable star unleashed a fierce solar wind.
6
And over time, this stream of charged particles pushed the remaining gas cloud farther and farther out, leaving only solid particles behind to clump together into rocks,
7
planetesimals, and finally, the rocky planets of the inner solar system that we know today.
8
And here's the problem.
9
Water, in the form of ice, couldn't have been one of the solid particles that stuck around to form our planet, because the early inner solar system was far too hot for frozen water,
10
and any water vapor would have been blasted away by the solar wind.
11
So if Earth didn't start off with water, how did we end up with such splendid oceans?
12
We know H2O wasn't manufactured here over the eons, because natural processes like combustion,
13
breathing and photosynthesis create and destroy roughly equal amounts of water, and either way, the amounts in question are so minuscule that they can't account for the abundance of water on the planet.
14
Since Earth's water was neither part of the original package nor manufactured here, it must have flown in from far away, on meteoroids or comets or other bodies originating in the outer solar system,
15
where they were far enough from the sun for frozen water to survive.
16
The dirty ice balls we call comets are a logical candidate for the source of our water, but were ruled out when we discovered that they were far richer in heavy hydrogen than earth water.
17
Heavy hydrogen has a neutron as well as a proton in its nucleus, and for every million hydrogen atoms in earth water, about 150 are heavy ones,
18
while typical comet water has twice that many.
19
These mismatched chemical signatures suggest that Earth's water couldn't have arrived on comets.
20
It turns out that the most likely source for Earth's water is a type of meteorite called a carbonaceous chondrite.
21
Chondrite is just the name given to the class of stony meteoroids that most commonly strike the Earth.
22
But only the carbonaceous chondrites contain water, as well as lots of carbon if you couldn't tell from their name.
23
They have water in them because they formed out beyond the sun's frost line, and what's more, their water has levels of heavy hydrogen similar to that of earth water,
24
strongly suggesting that these earth crashers are the source of our ice caps, clouds, rivers, and oceans.
25
And thus the water that turned our planet into a blue marble came, quite literally, out of the blue.

इस पाठ की शब्दावली और बोलने के सुझाव

यह B2 स्तर का स्पीकिंग पाठ वीडियो “Where Did Earth's Water Come From?” पर आधारित है। सबसे ज़्यादा दोहराए गए शब्द ये हैं: solar, planet, earth, comet, hydrogen। इस वीडियो में शैडोइंग के लिए 25 वाक्य और 496 शब्द हैं। बोला गया हिस्सा 2:24 लंबा है। वक्ता तेज़ बोलता है, लगभग 206 शब्द प्रति मिनट, इसलिए जुड़ी हुई और कमज़ोर ध्वनियाँ ज़्यादा मिलेंगी। केवल 80% शब्द अंग्रेज़ी के 3,000 सबसे आम शब्दों में से हैं, इसलिए शब्दावली कठिन है।

इस वीडियो की मुख्य शब्दावली

वीडियो के 15 सबसे कठिन शब्द, उच्चारण और अर्थ के साथ:

शब्दउच्चारणअर्थ
comet संज्ञा/ˈkɒmɪt/धूमकेतु, केतुग्रह
hydrogen संज्ञा/ˈhaɪdɹəd͡ʒ(ə)n/उदजन, हाइड्रोजन
particle संज्ञा/ˈpɑɹtək(ə)l/कण, ज़र्रा
meteoroid संज्ञाउल्का
freeze क्रिया/ˈfɹiːz/जमना
meteorite संज्ञा/ˈmi.ti.əˌɹaɪt/उल्कापिंड
neutron संज्ञा/ˈnu.tɹɑn/नपुंसणु
photosynthesis संज्ञा/ˌfoʊ.toʊˈsɪn.θə.sɪs/प्रकाश-संश्लेषण
proton संज्ञा/ˈpɹoʊ.tɑn/प्रोटॉन, प्राणु

splendid विशेषण/ˈsplɛndɪd/तेजस्वी, शानदार
abundance संज्ञा/əˈbʌn.dn̩s/प्रचुरता, अधिकता
unstable विशेषण/ʌnˈsteɪ.bəl/अस्थिर

ध्यान देने योग्य उच्चारण

वक्ता 6 बार संक्षिप्त रूपों का प्रयोग करता है, जैसे couldn't, can't, didn't। इन्हें वैसे ही छोटा बोलें जैसा आप सुनते हैं।

  • “sh” और “zh” की ध्वनियाँ: carbonaceous /kɑːbəˈneɪʃəs/, unleash /ʌnˈliʃ/
  • लंबे शब्द — बलाघात सही रखें: carbonaceous /kɑːbəˈneɪʃəs/, meteorite /ˈmi.ti.əˌɹaɪt/, originate /əˈɹɪd͡ʒɪneɪt/, photosynthesis /ˌfoʊ.toʊˈsɪn.θə.sɪs/

हिंदी भाषियों के लिए मुश्किल ध्वनियाँ:

  • /æ/ — “ऐ” से ज़्यादा खुला: mismatch /ˈmɪs.mæt͡ʃ/, atom /ˈætəm/, collapse /kəˈlæps/

इस वीडियो से अभ्यास कैसे करें

  1. पहले बिना बोले पूरा वीडियो एक बार सुनें और जो शब्द नहीं आते उन्हें लिख लें।
  2. 0.75× गति से शुरू करें, एक-एक वाक्य की शैडोइंग करें, और सहज लगने पर सामान्य गति पर लौटें।
  3. अपनी आवाज़ रिकॉर्ड करें और मूल से तुलना करें, ख़ासकर comet, hydrogen, particle जैसे शब्दों पर ध्यान दें।

शैडोइंग तकनीक क्या है?

शैडोइंग (Shadowing) एक विज्ञान-समर्थित भाषा सीखने की तकनीक है जो मूल रूप से पेशेवर दुभाषिया प्रशिक्षण के लिए विकसित की गई थी। विधि सरल लेकिन शक्तिशाली है: आप मूल अंग्रेज़ी ऑडियो सुनते हैं और तुरंत इसे ज़ोर से दोहराते हैं — जैसे वक्ता की छाया 1-2 सेकंड की देरी से। शोध से पता चलता है कि यह उच्चारण सटीकता, स्वर, लय, जुड़ी हुई ध्वनियाँ, सुनने की समझ और बोलने की प्रवाहशीलता में काफ़ी सुधार करता है।
