Quora answers need not be 100% correct answers .Compiled and posted byR. Gopala krishnan, on 20-10-2023 Q1 Why is the sea salty? Where did it getits salt from? A1 Amit Shriqui, Updated Jul 14 The sea is salty, and you might wonder where itgets its salt from. The primary sourceof salt in the ocean is the continuous process of erosion and weathering. When rain falls on land, itdissolves minerals, including salts, from rocks and soil. Rivers carry thesedissolved salts into the oceans over time. Additionally,volcanic activity and underwater hydrothermal vents contribute small amounts ofminerals to the seawater. The accumulation of salts, primarily sodium chloride (table salt), over millionsof years has made the sea salty. So, it's the combination ofweathering, erosion, and geological processes that give the sea its saltynature. Q2 Does light reach Saturn's surface? Ifso, 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 isquite 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. Duringsunset or sunrise, you can see a very small glow (which is the sun) in thehorizon. Also, the large rings orbiting the planet can create unique visuals: Thesebeautiful visuals occur as a result of water ice and other particles refractingthe sunlight. But to answer your second question, Saturn wouldlook incredibly dim at night (which is not a surprise, as light doesn’t quite reach thenight side of the planer, or any planet in fact), though some light may reachdue to reflection from the rings. NOTE:I gave the best answer I can for this and didas 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 nothingfor you. Responding to pointless emails. Email may be oneof the biggest time-sucking black holes. Too much socializing. Don’t be afraid to tellothers that you’re busy and need to stayfocused right now. Online distractions. A source of unlimitedinformation, entertainment, shopping and amusement right at your fingertips isactually a big time waster. Too many breaks. Little break can turn into a bigwaste of time. Q4 What was incredibly expensive twentyyears ago, and is completely worthless today? A4 Claire,upvoted1h,Hugh Caley, self-taughtsoftware developer and system administrator5h Some time around 1996 I bought an Apple QuickTake 200 digital camera. I think itcost about $600. The output was color images at 640x480 pixels. That’s around1/3 of one megapixel. When I was young my dad built us a dark room. Wehad an old SLR and we’d develop black and white photos (color was a lot moreexpensive and dangerous for the kids). I eventually lost interest in doing thework required. When this thing became available I bought itgleefully, and used it for several years. Despite the poor resolution I knewthis was the future. No development required. No film required. I could loadthe pics on my Mac and manipulate them directly. Color. It was awesome. Thephotos were so poor that they certainly couldn’t be used in any professionalway. I didn’t care. Nowadays my iPhone 15 photos have up to 48megapixels. It has hardware zoom and can shoot wonderful night pictures. But itall started here for me. My note- In the year 2000, I purchased my HPcomputer 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, stillproblem persisted. Now I could purchase my Asus laptop for just Rs 38000-00 in 2021. Ifind the Computer was a little bit waste since the ORIGINAL HP computer did not perform well for the amountspent in 2000. Q5 What is the white vapor that planesblow into the cabins? A5 Rebecca Williams, Credit Analyst(2019–present)Sep 13 The white vapor that you see on planes blowinginto 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 thewarm and humid air from the outside, which is brought into the cabin when thedoor is open. The cold airlowers the temperature below the dew point, which is the point at which the aircan no longer hold all the water vapor in it. The excess water vapor then turns into tiny droplets ofliquid water, which are visible as a white mist or fog. This is also known asan 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 therest of the cabin. The air conditioning system also recirculates anddehumidifies the cabin air, making it dryer and less prone to condensation. The white vapor is harmless and doesnot affect the safety or comfort of the passengers or crew. It is morecommon in hot and humid climates, especially in summer, and when the plane isparked on the ground. -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
