What is the atmosphere made up of?

The word 'Atmosphere' means a gaseous cover enveloping a planet. without atmosphere life would not have been possible on the Earth: One-fifth of the atmosphere is oxygen and fourth-fifth is nitrogen. Like the earth's interior, the atmosphere too is made up of several layers.All animals and plants live in the lowermost layers of the atmosphere called the 'troposphere'. All weather phenomena take place in the troposphere. Even aeroplanes fly in the outer edge of the troposphere. The stratosphere, the mesosphere,the ionosphere, and the exosphere lie above the troposphere.

How are new seas formed?

How are new seas formed?     Seas arise at place where the Earth's crust cracks open due ti expansion.Around 200 million years ago the Atlantic was formed in this way. Today in Earth Africa,a crack from Malawi to Ethiopia has formed as a result of the eruption of a volcano. If the soil sinks further, water from the oceans will enter  the region to give rise to a water body. this has already happened in the case of Red sea, the continuation of the east African rift system. If the plate continues to expand,then at some point of time it breaks completely giving rise to a long mid-ocean volcanic ridge.                                                                                                      ...

How many plates does the Earth's crust have?

How many plates does the Earth's crust have? The relatively solid earth's crust and a part of the layer that lies below it-is divided into seven large and more than smaller plates. These plates float over the hot , viscous layer, which is constantly in motion-like boiling soup. These flushes of heat in the Earth's interior are known as 'convection cells' at places where the convection currents push the rocks upwards , the crust often breaks and gives rise to a new crust. For example, the mid-ocean ridges in the Atlantic and Pacific oceans.           If you like this blog please comment down below                                                                                                       ...

Why are some planets so big?

Why are some planets so big?             The largest planets of solar system are the  planets Jupiter and Saturn. Both planets have distinct bands around them with stripes. Saturn  can be recognized easily by its rings. Uranus , uniquely tilted sideways, and the blue Neptune , the coldest of the outer planes, are also much Larger then the inner planets. The outer planets are so big because they are comprised mainly of gases such as helium and hydrogen. These planets have a solid core, which is surrounded by liquid or frozen gas. This reason why they are also known as "gas giants" .
