- The main point of the paragraph is that stars are not actually twinkling; their light is being bent and scattered by Earth's atmosphere, which makes them appear to twinkle.
- A star is a huge ball of hot gases, mostly hydrogen and helium, that gives off light and heat.
- We see stars as twinkling because their light passes through Earth’s moving atmosphere, which bends and scatters the light, causing it to appear to flicker or change brightness.
- The kind of sentence that introduces the passage is a question: “Have you ever wondered why stars seem to twinkle?”
- Words such as “because,” “but,” and “which means” are used as transition words to connect ideas and show relationships between sentences. They help guide the reader through the explanation by indicating cause, contrast, or clarification.
