Exploring Cause and Effect in Text Structure

The video tutorial by Miss Tart explores the cause and effect text structure, using the historical context of wolves in Yellowstone National Park as an example. It discusses the impact of overhunting wolves, leading to a trophic cascade that disrupted the ecosystem. The reintroduction of wolves in the 1990s helped restore balance. The video also provides practice in identifying cause and effect in texts, highlighting key words and phrases that signal this structure.
