2. Describe the following:

a. A shield-type volcano as compared to a composite volcano

"Skjaldbreiður", an Icelandic shield volcano whose name means "broad shield."

A shield volcano is a large volcano with shallowly-sloping sides. Shield volcanoes are formed by lava flows of low viscosity — lava that flows easily. Consequently, a volcanic mountain having a broad profile is built up over time by flow after flow of relatively fluid lava issuing from vents or fissures on the surface of the volcano. Many of the largest volcanoes on Earth are shield volcanoes. The largest is Mauna Loa on the Big Island of Hawaii.
