Briefly describe the solar nebula hypothesis

Explanation:

The solar nebula hypothesis -

It is the hypothesis , which describes the formation of the solar system from the nebula cloud , which is composed of gas and dusts .

The belief is that , the sun , moon , planets and the asteroids are formed from the nebula , around 4.5 billion years ago .

Nebula - is basically an interstellar cloud of the dust and gases .

The main phenomena for the formation of a celestial boy is the gravity .

The gravity condenses the gas into a region of density .

The denser region began to grow and act as a seed to further build a full fledged planet or any celestial body .

a mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. this uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.a geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
