Let's break down your questions step by step. ### Mt. St. Helens 1. **What Ridge is it a part of?** - Mt. St. Helens is part of the Cascade Range, which is a mountain range in the Pacific Northwest of the United States. 2. **What type of plate boundary is found here?** - The Cascade Range, including Mt. St. Helens, is located at a convergent plate boundary where the Juan de Fuca Plate is subducting beneath the North American Plate. This subduction leads to volcanic activity in the region. ### Hawaiian Islands 1. **How did the Hawaiian Islands form?** - The Hawaiian Islands were formed by volcanic activity as a result of a hotspot in the Earth's mantle. As the Pacific Plate moves over this stationary hotspot, magma rises to the surface, creating volcanoes. Over time, these volcanoes can build up to form islands. 2. **Hawaii is found under what plate?** - Hawaii is located on the Pacific Plate. 3. **Is it found at the boundary of two plates?** - No, the Hawaiian Islands are not located at the boundary of two tectonic plates. Instead, they are situated in the middle of the Pacific Plate, away from any plate boundaries. 4. **What is important about the Big Island of Hawaii?** - The Big Island of Hawaii is significant because it is home to the most active volcanoes in the world, including Kilauea and Mauna Loa. It is also the youngest of the Hawaiian Islands, having formed from recent volcanic activity. Additionally, the Big Island has diverse ecosystems and is the largest island in the Hawaiian archipelago. If you have any more questions or need further clarification, feel free to ask!
