Amazing Earth
Our earth is more than 4.5 billion years old, but recent studies suggest that it is still older. More than two million cubic miles of fresh water is assessed to be stored in the earth. We all now know that the earth is the only planet that can hold water in liquid form on the surface. Concentrated ozone molecules are present in the ozone layer, which is more than 50 km in thickness, but we are causing damage to this protective layer by global warming. The bulge of the earth earlier noted by the experts as decreasing is now noticed to be increasing resulting in the slowdown of its rotation. Our Earth is now known to have another moon by name “3753 Cruithne" . Though there are more than 5 to 30 million different species on the earth, only about two million of them have been identified so far. Early astronauts had seen our eEarth from the space and called it the Blue Planet Remember Yuri Gagarin’s words? “The earth is so beautiful. Seeing ithe Earth for the first time, I could not help but love and cherish her.’

No doubt the earth is lovely, but it also contains wild volcanoes as well as devastating earthquakes. Extremes of climate are all too familiar to all of us. Deep oceans and tall peaks make our Earth a truly amazing planet.
