Which type of volcano forms a mountain with gently sloping sides and is built almost entirely from thin lava?
Shield volcanoes
Shield volcanoes, the third type of volcano, are built almost entirely of fluid lava flows. Flow after flow pours out in all directions from a central summit vent, or group of vents, building a broad, gently sloping cone of flat, domical shape, with a profile much like that of a warrior’s shield.
What is a volcano with gently sloping sides?
1. As quiet eruptions of basaltic lava spread out in flat layers, they form a broad volcano with gently sloping sides called a shield volcano.
Which type of volcano is gently sloping?
Shield Volcano
A dome shaped volcano with gently sloping sides and a broad base characteristic of relatively low viscosity, basaltic lava eruptions.
Which type of volcano has gentle slopes and forms at a divergent plate boundary?
Shield volcanoes are found on divergent plate boundaries , where two plates move away from one another.
Which of the following has gently sloping sides and a broad base?

Which type of volcano has gently sloping sides and erupts Nonexplosively?
Shield volcanoes are huge, gently sloping volcanoes built of very thin lava spreading out in all directions from a central vent. They have wide bases several miles in diameter with steeper middle slopes and a flatter summit.
Which volcano is usually low with gently sloping sides this volcano is not steep and is wide?
Shield volcanoes are huge, gently sloping volcanoes. Cinder cones are small, cone-shaped volcanoes.
What is the difference between a steep and flatter volcano?
Volcanoes with steep slopes tend to form from very viscous magma, while flatter volcanoes form from magma that flows easily. Lava (magma that has erupted onto the Earth’s surface) is visually mesmerizing – as the molten rock flows downhill, lava exposed to the air cools to a deep black color, while the molten rock beneath glows bright orange.
What is the internal structure of a shield volcano?
The internal structure of a typical shield volcano S hield volcanoes, the third type of volcano, are built almost entirely of fluid lava flows. Flow after flow pours out in all directions from a central summit vent, or group of vents, building a broad, gently sloping cone of flat, domical shape, with a profile much like that of a warrior’s shield.
How does the type of magma affect the shape of volcanoes?
The viscosity (thickness) of the magma that erupts from a volcano affects the shape of the volcano. Volcanoes with steep slopes tend to form from very viscous magma, while flatter volcanoes form from magma that flows easily.
What are the essential features of a composite volcano?
The essential feature of a composite volcano is a conduit system through which magma from a reservoir deep in the Earth’s crust rises to the surface. The volcano is built up by the accumulation of material erupted through the conduit and increases in size as lava, cinders, ash, etc., are added to its slopes.
