Question

how does a rock and star
form​

Answer 1

Answer:

Explanation:

Rocks-There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks is formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.

Stars-Stars are born within the clouds of dust and scattered throughout most galaxies. ... Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. As the cloud collapses, the material at the center begins to heat up.
