Formation Of The Solar System 6 Steps

The collapse may have been caused by a cataclysmic event.

2 gravity pulled most the matter towards the center and the cloud spun faster. The formation and evolution of the solar system began 4 5 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. Terms in this set 6 step 1. Meteorites comets and asteroids are survivors of the solar nebula out of which the solar system formed.

Approximately 4 6 billion years ago the solar system was a cloud of dust and gas known as a solar nebula. It so happened that the solar nebula began collapsing under its own gravitational force. 4 heat from the sun. A viable theory of solar system formation must take into account motion constraints chemical constraints and age constraints.

5 billion years ago the sun formed from a cloud of gas and dust that collapsed because of gravity. 1 started as swirling could of gas and dust called a nebula. Gravity collapsed the material in on itself as it began to spin forming the sun in the. According to this nebular theory the solar system was formed from a massive rotating cloud of dust and gas called the solar nebula.

Our story starts about 4 6 billion years ago with a wispy cloud of stellar dust. After the cloud collapsed it formed into a rotating disk. Very dense and hot in the center where the star began to form. An interstellar cloud of gas that is known as the solar nebula collapsed under its own gravity.

This cloud was part of a bigger cloud called a nebula. But how did this busy stellar neighborhood come to be. The solar system is a pretty busy place. A star is born.
