How does the way in which the solar system formed and explain the orbits, size and composition of the planet

DUE TO GRAVITATIONAL COLLAPSE SOLAR SYSTEM IS FORMED , ORBITS ARE CURVED TRAJECTORIES AND SIZE AND COMPOSTION OF PLANET ARE VERY UNIQUE AND COMPOSED OF ROCKS AND METALS.

Explanation:

The formation and evolution of solar system has began 4.5 billion years ago,due to gravitational collapse of a small particle from a giant cloud.

The solar system was formed through tidal interactions which took place between a protostar having low density and the sun.

an orbit is the gravitationally curved trajectory of an object. To a close approximation, planets and satellites follow elliptic orbits, with the center of mass being orbited at a focal point of the ellipse

The planets in our solar system are each very unique for various reasons. When it comes to their measurable sizes in diameter, the planets vary greatly. Jupiter, for example, is approximately 11 times the diameter of the Earth. Mercury, on the other hand, is 2.6 times smaller in diameter than the Earth.

The giant planets have dense cores roughly 10 times the mass of Earth, surrounded by layers of hydrogen and helium. The terrestrial planets consist mostly of rocks and metals. They were once molten, which allowed their structures to differentiate

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
