Which evidence can be used to classify a nebula select the two correct answers shape location in the sky interaction with light distance from Earth

Answer 1

To classify a nebula, the two most relevant pieces of evidence are:

1. Shape: The shape of a nebula can provide insights into its type (e.g., planetary nebulae, supernova remnants, emission nebulae, etc.) and how it has evolved.

2. Interaction with Light: How a nebula interacts with light can help classify it, such as whether it emits light (like emission nebulae), reflects light (like reflection nebulae), or absorbs light (like dark nebulae).

Location in the sky and distance from Earth are less directly useful for classification purposes.
