Main Idea: Types of Volcanoes

Main Idea: Types of Volcanoes. A. How does a Shield volcano form?. They form when layers of lava accumulate over time. The eruptions are slow and nonexplosive. Shield volcanoes are the largest in size. B. How does a Cinder-Cone volcano form?.

Three Types of Volcanoes

Three Types of Volcanoes. Shield Volcanoes. Low silica level Low viscosity Lava High or low levels of gas Low to medium explosivity Flattened mound Resembles a warrior’s shield. Mauna Loa, Hawaii. Piton de la Fournaise. Surtsey, Finland. Composite Volcanoes. High in silica

TYPES OF VOLCANOES

TYPES OF VOLCANOES. What is a volcano?. Any opening in the crust through which magma has reached the surface. What is the opening called?. The vent. What is lava?. Magma that has reached the surface and cooled. Answer these questions. What do you call lava while it is still in the mantle?

Types of Volcanoes and Volcanic Hazards

Types of Volcanoes and Volcanic Hazards. Earth and Space Science. Types of Volcanoes. 1 . Shield volcanoes - Lava flows a great distance before having a chance to cool - Forms a very broad volcano with gentle sloping sides as more lava flows over previously cooled lava.

Types of Volcanoes and Lava

Types of Volcanoes and Lava. Shield volcanoes. Shield volcanoes are very large and have gradual slopes. They look like mountains. Shield volcanoes rarely erupt violently. Their eruptions consist of large lava flows. The lava is smooth and slow moving. Shield volcanoes. Shield volcanoes.

TYPES OF VOLCANOES

TYPES OF VOLCANOES. COMPOSITE VOLCANOES. This type of volcano has both pyroclastic ash layers and lava flows. These volcanoes are steep sided near the summit but decrease in slope at the base. COMPOSITE VOLCANOES.

Types of Volcanoes

Types of Volcanoes. Shield, Composite, Cinder , Dome, Super or Caldera. Shield Volcanoes. Hawaii, Iceland, Galapagos Islands Made almost entirely from fluid lava flows Basaltic lava, generally non-explosive due to low silica content Gently sloping sides, sometimes kilometres wide.

Types of Volcanoes

Types of Volcanoes. Chapter 11 Section 2. Types of Eruptions:. Quiet Explosive Determined by: Amount of water vapor/trapped gases in the magma. Amount of silica (silicon and oxygen) in the magma. Quiet Eruptions. Contain basaltic magmas Low in silica Flows very easily
