Final answer:
Shield volcanoes are formed by thin lava spreading from a central vent, resulting in broad, gently sloping volcanoes. They have low viscosity lava that flows easily and creates wide, flat layers over a large area.
Step-by-step explanation:
Slowly formed out of thin lava spreading from a central vent, shield volcanoes are broad, gently sloping volcanoes that are typically found at hot spots or over mantle plumes. They are characterized by their low viscosity lava, which allows it to flow easily and create wide, flat layers over a large area. Examples of shield volcanoes include Mauna Loa in Hawaii and the Galapagos Islands.
