Your NOSE bleeds at Higher Altitudes - WHY??

             Sometimes when we climb up the hill, our NOSE starts bleeding at high altitudes. This occurs especially in WINTER season. There are so many reasons for NOSE BLEEDS. But, bleeding of NOSE at high altitudes and Cold temperatures are because of surrounding WEATHER CONDITIONS. Lets know what this changing weather does to our Body.


             Here are the changes in our Surrounding that occurs at HIGH ALTITUDES.

Why is VENUS TRANSIT RARE?? - The Facts behind its RARE occurrence

           A Transit of VENUS means the Planet VENUS passing directly between the SUN and the EARTH. This is a very RARE ALIGNMENT of STARS which occurs in our Solar System.

             The Speciality of this Event is the Frequency of its OCCURRENCE. The Occurrence of this event is not UNIFORM. This Transit of VENUS occurs in PAIRS.  The Transit took place in 2004 and after 8 years its happening again now ( June 2012). We can't see this TRANSIT again because we have to wait for another 105 years for another PAIR of TRANSITS with 8 years of gap between them. Then the pattern repeats (121 ½ , 8, 105 ½ , 8).

Why are Hill Stations COOLER??

           Small kids often ask this question when they visit a HILL STATION. Why is it Cool here? We are closer to the SUN now??  This question may sound stupid but we struggle to answer it.

            The drop in temperature at Hill Stations and Mountains is because of the  change in ATMOSPHERIC PRESSURE. There is a relation between PRESSURE and TEMPERATURE. Both Pressure and Temperature vary proportionally. This is what THERMODYNAMICS says. But I hate equations and formulas. Let's have a practical explanation and good understanding of this FACT

ICEBERG is Heavier but floats on Water - How?!!

            The Image what comes to my mind on hearing the word "ICEBERG" is TITANIC. A huge ICEBERG floating on the ATLANTIC made HISTORY. As we know, an ICEBERG is a piece of ICE broken from a GLACIER. One important thing is that ICEBERGS are made of FRESH WATER. They are heavy enough to submerge 89 % of their body, which means only 11 % is seen above the Water level.
            

Do SEA SHELLS have in-built SPEAKERS??

        Sea Shells found on the Sea shores are hard covers protecting the Soft backbone less SEA ANIMAL present inside. These shells get washed up and are found on the BEACH, after the animal present inside dies. Shells have been used for various purposes. Sea shells were even used as CURRENCY in many ISLANDS.

        These Empty Sea Shells produce some sound which you hear when you hold it near to your EARS. People were confused about from where this SOUND came.
