 Importance of snakes in the environment. Today we talk about the importance of snakes, people often ask why they always give so much importance to snakes and talk about their safe rescue.  So today let's talk about why snakes are necessary, by the way, Allah Almighty has not created anything in this universe for nothing, whatever it may be. Be it a lizard, a cockroach, a dragonfly, anything, But we are talking about snakes. 1. Snakes hunt mice and squirrels and balance their numbers, because if their numbers are not balanced, they damage crops and stockpiles. Some tree-dwelling (arboreal) snakes eat locusts that damage crops.  Tree-dwelling snakes such as 1. Bronzeback tree snake (dendrelaphis tristis). 2. Asian vine snake (Gunther snake). 3.

 Assalam Alaikum, I hope all the readers are doing well, before that we know that scientists have divided the earth into four main layers based on the different places of the earth and the different characteristics of these places. And those are the four basic layers The lithosphere   Hydrosphere Biosphere And the atmosphere. If anyone wants links to this post then comment, Today we will learn more about atmosphere, Our atmosphere surrounds our earth from all sides be it north, south or east or west. Our atmosphere is divided by scientists into different zones based on their changing temperature, Atmospheric pressure at the surface of the Earth is atm. And this pressure decreases as you rise above the surface of the earth. Scientists divide the atmosphere into the following four zones, The troposphere The stratosphere Mesosphere and Thermosphere Today we will learn about only one zone, Troposphere. It is the first layer of the atmosphere which is very close to the earth's surf...

 When was the earth formed? Written by Dr. Hafeezul Hasan Has the earth always existed?  Will the earth always shine?  This question is important.  Why?   Because we were born on this earth. We live on this earth.  Our ancestors are buried here. Their ancestors before them.  Everything in the universe has an end.  The cause is the flow of time between the two events of survival and annihilation. So this question comes to mind that when the earth was created and when will the earth end? There is no birth certificate of the land to see its date of birth, nor can the people of Nadra tell when it was born? So how to estimate the time of his birth? Ever since we learned science in modern ways, we have been in a quest to learn as much as we can about the earth, the universe, and life. For the past four hundred years, scientists have been considering different methods for determining the age of the Earth. The first method was thought to be the age of the...

 In Africa, giant buffaloes are grazed by small beaked sparrows that not only feed on leeches and other insects hidden in their hair, but when danger is lurking around, they quickly start to fly away and make a noise.  A buffalo gets smarter as you grow up nature attaches many small and weak characters to you we often think of them as burdens but they are not burdens they are nature's protective shield which says you are mine.  Feed the weak, I will maintain your dignity and strength.
