Free 8th grade reading passage with text-dependent questions: How Volcanoes Erupt
How Volcanoes Erupt is an original, fact-checked 8th grade earth science passage of about 650 words. It explains where magma forms, why gas makes it rise, and why some volcanoes erupt gently while others explode. Students answer six text-dependent questions (three found in the text, three that ask them to think with it), fill a main idea organizer, and the teacher gets an answer key.
