This is writing so innocently , keeping the truth hidden. I never said Q and A is a waste of time; Major- Quora is a waste of time. There is some good stuff also but Mr G never reads them because they are better knowledge than Mr G and also Mr G cannot reveal his strength. G's Qura write up by Mr G is accepted as not reliable; so unreliability is a waste; but right write up is a waste of time only for Nr G since he cannot expose his incredibility (?) . Even when writing 2 lines Mr G loses the reality. Thanks K R IRS 21 10 23

KR So did you mean to say once seawater was tasty but became salty only later on? Another source of salts in the ocean is hydrothermal fluids, which come from vents in the seafloor <https://oceanservice.noaa.gov/facts/vents.html>. Ocean water seeps into cracks in the seafloor and is heated by magma from the Earth’s core. The heat causes a series of chemical reactions. The water tends to lose oxygen, magnesium, and sulfates, and pick up metals such as iron, zinc, and copper from surrounding rocks. The heated water is released through vents in the seafloor, carrying the metals with it. Some ocean salts come from underwater volcanic eruptions, which directly release minerals into the ocean. Sodium and chloride are common chemicals even before sulphur, phosphorus, hydrogen helium etc as all water is saline; but by running process and heavy quantum of water in the rivers and lakes, heavy solids gets filtered and enters crevices if the land or earth, transmitting them as absorptions in another place where through crevices, water entering takes these salts from the earth; so river water is sweet and rejected ones are saltier; in case of reverse osmosis, internal water might get back the salinity perhaps; but for the procwess it shall run and shall not churn; have you not seen by churning froth appears to expand as large; so reverse osmosis can never happen in the sea. Q2 Does light reach Saturn's surface? If so, what is it like on Saturn at night? KR A day on earth is 24 hours; but as Saturn revolves by itself so speedily, its day is just 10 hrs and 33 minutes only. Earth 845 days makes earth equivalent to a year. Saturn will have 2.3 times more days while earth has a day. The rings A to G, a gaseous state, is unique in the sense, it creates a lot of pressure, least light, and except B ring no obvious light. The southern side almost 10% is brighter in a part of 10.33 hrs; the moons all around many moons makes it colder though the Moon TITAN is a liveable place. The heat generated in Saturn is so huge that habitability is blank. Sun Rays take almost 10 times more than the earth to get the light. Q3 What is a waste of time? KR True majority of Quora is a waste of time. Can the waste of time of others become the capital for a few? Yes, for so many earning a lot use the waste of time of the customers. Q4 What was incredibly expensive twenty years ago, and is completely worthless today? KR All things bought at the tides is costlier than who bough later; iphone 12 you can buy for a song which at the tide was 98000 rupees. However, in economics, customer satisfaction is higher than the cost.

Gopala krishnan, on 20-10-2023* *Q1 Why is the sea salty? Where did it get its salt from?* *A1 Amit Shriqui, Updated Jul 14* *The sea is salty, and you might wonder where it gets its salt from.** The primary source of salt in the ocean is the continuous process of erosion and weathering. When rain falls on land, it dissolves minerals, including salts, from rocks and soil. Rivers carry these dissolved salts into the oceans over time. * *Additionally, volcanic activity and underwater hydrothermal vents contribute small amounts of minerals to the seawater. The accumulation of salts, primarily sodium chloride (table salt), over millions of years has made the sea salty. So, it's the combination of weathering, erosion, and geological processes that give the sea its salty nature.* *Q2 Does light reach Saturn's surface? If so, what is it like on Saturn at night?* *A2 Scientist Wannabe, Former Student16h* *Light from the sun reaches as far as the Kuiper belt,** no matter the time it takes to reach it.* *Saturn is quite far from the sun - about 886 million* *miles (1.43 billion km). However, you can still see some light, if not bright, reaching its surface.* *During sunset or sunrise, you can see a very small glow (which is the sun) in the horizon. Also, the large rings orbiting the planet can create unique visuals:* *These beautiful visuals occur as a result of water ice and other particles refracting the sunlight. But to answer your second question, Saturn would look incredibly dim at night (which is not a surprise, as light doesn’t quite reach the night side of the planer, or any planet in fact), though some light may reach due to reflection from the rings.* *NOTE:I gave the best answer I can for this and did as much research as I could for this**. I know this is very vague, so if there was anything I missed or could’ve added, please let me know.* *Q3 What is a waste of time?* *A3 Matthew Cooper,Young Entrepreneur / BloggerApr 17* *Gossiping. Talking about other people does nothing** for you.* *Responding to pointless emails. Email may be one** of the biggest time-sucking black holes.* *Too much socializing. Don’t be afraid to tell others** that you’re busy and need to stay focused right now.* *Online distractions. A source of unlimited** information, entertainment, shopping and amusement right at your fingertips is actually a big time waster.* *Too many breaks. Little break can turn into a big** waste of time.* *Q4 What was incredibly expensive twenty years ago, and is completely worthless today?* *A4 Claire,upvoted1h,Hugh Caley, self-taught software developer and system administrator5h* *Some time around 1996 I bought an Apple Quick** Take 200 digital camera.* *I think it cost about $600. The output was color images at 640x480 pixels. That’s around 1/3 of one megapixel.* *When I was young my dad built us a dark room. We** had an old SLR and we’d develop black and white photos (color was a lot more expensive and dangerous for the kids). I eventually lost interest in doing the work required.* *When this thing became available I bought it** gleefully, and used it for several years. Despite the poor resolution I knew this was the future. No development required. No film required. I could load the pics on my Mac and manipulate them directly. Color. It was awesome. The photos were so poor that they certainly couldn’t be used in any professional way. I didn’t care.* *Nowadays my iPhone 15 photos have up to 48** megapixels. It has hardware zoom and can shoot wonderful night pictures. But it all started here for me.* *My note- In the year 2000, I purchased my HP** computer for Rs 75000-00, It hardly worked for 5 years, it had starting problem, PSU problem and mother board problem. HP replaced mother board in warranty period, still problem persisted. Now I could purchase my Asus laptop for just Rs 38000-00 in 2021. I find the Computer was a little bit waste since the ORIGINAL HP computer did not perform well for the amount spent in 2000. * *Q5 What is the white vapor that planes blow into the cabins?* *A5 Rebecca Williams, Credit Analyst (2019–present)Sep 13* *The white vapor that you see on planes blowing into the cabins is actually a form of condensation,** similar to what you see when you breathe out on a cold day. It happens when the air conditioning system of the plane cools down the warm and humid air from the outside, which is brought into the cabin when the door is open.* *The cold air lowers the temperature below the dew point, which is the point at which the air can no longer hold all the water vapor in it. The excess water vapor then turns into tiny droplets of liquid water, which are visible as a white mist or fog. This is also known as an aerosol of water droplets.* *The white vapor usually disappears quickly**, as the droplets evaporate back into the air or mix with the warmer air in the rest of the cabin. The air conditioning system also recirculates and dehumidifies the cabin air, making it dryer and less prone to condensation. The white vapor is harmless and does not affect the safety or comfort of the passengers or crew. It is more common in hot and humid climates, especially in summer, and when the plane is parked on the ground.* -- You received this message because you are subscribed to the Google Groups "iyer123" group.
