Which of these describes a nebula?(1 point)
Responses
star much larger than the sun
star close in size to the sun
cloud of gravity and pressure
cloud of gas and dust
cloud of gas and dust
The correct response is:
cloud of gas and dust
The correct response that describes a nebula is "cloud of gas and dust."
To arrive at this answer, we can analyze the options given and determine which one accurately represents the characteristics of a nebula.
Option 1, "star much larger than the sun," does not describe a nebula. A nebula is not a star, but rather a cloud-like formation in space.
Option 2, "star close in size to the sun," is also incorrect. As previously mentioned, a nebula is not a star, so this option does not accurately describe what a nebula is.
Option 3, "cloud of gravity and pressure," is not an accurate description of a nebula. While gravity and pressure play a role in the formation and evolution of a nebula, this option does not fully encompass the characteristics of a nebula.
Option 4, "cloud of gas and dust," is the correct answer. A nebula is a vast, cloud-like region of gas and dust in space. Nebulas are often regions where new stars are born or where old stars release their outer layers at the end of their life cycle.
Thus, the correct answer is that a nebula is a "cloud of gas and dust."
