Moon that leaks !!!!

  By moon, I mean natural satellite of a planet   !!!

1.  This moon is the moon of second largest planet in solar system.

2.  It continuously blasts water vapour and ice grains directly into space  !!!

3.  This moon has a hidden ocean buried beneath its frozen crust.

4.  It holds a warm reservoir of  liquid saltwater !!!

5. The leaks escape through 4 massive, parallel volcanic fissures near its South Pole.

This is           ENCELADUS     !!!!

It is a tiny, ice covered moon orbiting Saturn.

Saturn's immense gravitational pull stretches and compresses the moon.

This generates immense friction and heat that prevents the subsurface water from freezing cold.

This phenomena gives scientists an idea about how life formed on Earth.......

Why do brand new concrete cracks so fast ???

 Brand new concrete cracks because it shrinks while it is drying.

Think it as the wet mud .....

When mud dries in Sun, it cracks. Same with concrete  !!!

Why it happens fast   ???

1.  Top layer dries fast , but inside it remains wet.....

       So it pulls and cracks.

2.  Too much water in concrete mix.

      More water  =  more cracks later   !!!

3.  New slab needs water daily for 7 days.

      If no water, it cracks.......

4.  Big slab needs small cuts.

      If no cuts provided, it will crack anywhere it wants   !!!

5.  If ground below is soft, slab goes down and cracks.......

Simple fix   :

             Less water in mix.

              Keep it wet with water for  7 days .....

Why apple is called false fruit ??

 In botany, 

A true fruit develops only from the ovary of flower 

Ex :   Mango ,  Peach 

But in apple it does not happen like that.  

In Apple flower, a region called thalamus or the base of the flower grows and becomes fleshy.

We eat that part  !!!

Actual true fruit is the small core inside that contains the seeds.

  

As apple is developed from other parts of flower along with ovary, in this case it is the base of the flower  !!!

Apple is called false fruit  !!!!

Other ex :  Cashew ,  Strawberry
