Answer Details

The subject matter of the passage is an earthquake. The passage describes the sudden movement of the earth, causing the destruction of houses and mountains. The phrase "the towering earth was tired of sitting in one position" suggests that the earth had been still for a long time, and the sudden movement was unexpected. The use of words such as "crumbled", "heaved" and "lost" further reinforces the idea of destruction and chaos caused by the earthquake. Therefore, it can be inferred that the subject matter of the passage is an earthquake.
