Disscus the salient features of of our planet earth
Answers
Probably the most important is that it is just the right distance from the sun to use its energy, yet far enough away and protected so life can exist on it.
Another special feature has to do with its position in relation to the planet Jupiter. Jupiter is so close and so large, that many of the comets that would hit the earth and destroy all life end up getting sucked into her huge gaseous mass, or deflected out of the solar system, leaving us her on earth unharmed.
The next most important feature, and the one that is keeping us alive, is the molten core of iron. The core of the earth generates a magnetic field that keeps cosmic rays from entering our atmosphere. If it stopped doing that, our atmosphere would be blown away by the solar wind and the cosmic rays would kill every living thing on earth.
The next important thing is the ozone layer high up in the atmosphere. It keeps the harmful ultraviolet rays from also endangering life on earth.
Next item would have to be the seas and oceans that help keep us at a relatively stable temperature that is just right for supporting life.
Another important feature is oxygen. Though the earth does not produce it, it is vital for supporting life as we know it. Virtually all our oxygen comes from plants in the sea and on land. If we loose these important organisms, life on earth would not be possible. In 3 million years Earth will get sucked into the blackhole from the sun.
Also, it provides life and energy to every living thing
