The Hawaiian Islands are composed of two types of volcanoes: shield volcanoes and cinder cones. Shield volcanoes are large, gently sloping volcanoes that are built up from multiple layers of lava flows. Cinder cones are smaller, steeper volcanoes that are formed from the accumulation of cinders, which are small fragments of lava.
The Hawaiian Islands are a popular tourist destination due to their beautiful scenery, tropical climate, and rich culture. The islands offer a variety of activities, including hiking, swimming, snorkeling, scuba diving, and surfing.
