Question
Which statement describes the formation of our sun? A disk formed of long trails of stars coiled into a spiral. It formed an elliptical flattened disk. Heat and gases contracted within a nebula. Gravity pushed stars away from a center core.
Solution
To answer the question about the formation of our sun, let's break down each statement step by step:
-
"A disk formed of long trails of stars coiled into a spiral."
- This describes the formation of a spiral galaxy, not the formation of a single star like our sun.
-
"It formed an elliptical flattened disk."
- This statement is more related to the formation of elliptical galaxies or the shape of certain celestial structures, not specifically the process of star formation.
-
"Heat and gases contracted within a nebula."
- This accurately describes the process of star formation. Stars, including our sun, form from the gravitational collapse of gas and dust within a nebula. As the material contracts, it heats up and eventually forms a protostar, which continues to gather mass and heat until nuclear fusion ignites in its core, forming a new star.
-
"Gravity pushed stars away from a center core."
- This statement is incorrect in the context of star formation. Gravity actually pulls material together to form stars, rather than pushing them away.
Therefore, the correct statement that describes the formation of our sun is: "Heat and gases contracted within a nebula."
