Answer 1

Shield volcanoes are characterized by their broad base, gentle slopes, and thick lava. They are formed from low-viscosity lava flows and have a flat profile.

Step-by-step explanation:

Shield Volcanoes

Shield volcanoes are a type of volcanic landform characterized by their broad base and gentle slopes. They are formed by the eruption of low-viscosity lava flows, such as basaltic lava, which spreads out over a large area. This results in the formation of a broad, shield-shaped volcano with relatively shallow slopes.

Features of Shield Volcanoes

• Broad Base: Shield volcanoes have a wide and flat summit area.
• Steep Sides: The sides of shield volcanoes are relatively gentle and slope gradually.
• Thick Lava: These volcanoes are composed of multiple layers of thin lava flows that build up over time, creating a relatively flat profile.
