Hot Spots | Volcano World | Oregon State University

A hotspot is thermally expanded buoyant mantle (bigger hot mantle that floats), which lifts an overlying plate. As hotspot material rises, the pressure drops so the hotspot begins to melt producing magma. In an oceanic hotspot environment, for example Hawaii, dark, silica-poor basalt magma is produced. The runny basalt forms broad sloping shield …

Shield Volcano

The characteristics of a shield volcano are as follows: Shield Volcanoes are composed of basaltic magma (high in temperature, very low on silica and gas content.) The lava erupted from the shield volcanoes are runny and non-acidic. As the erupted lava is runny, they flow long distances before they solidify, this results in the gentle sides of ...

4.5 Where are the Volcanoes?

This results in chains of volcanoes, such as the Hawaiian Islands (Video 4.5.1, from IRIS and Fig. 4.5.4). These islands are usually just "the tip of the iceberg" as they are often very large shield volcano es that lie under the water (Fig. 4.5.4). Shield volcanoes form by low-viscosity, mafic magma.

Clay | Volcano World | Oregon State University

You can construct models of the different types of volcanoes (composite, cinder cone, and shield) using clay. Sheets of clay would represent lava flows and small balls of clay (or layers of sand) would represent fragmented lava or ash. This model of a stratovolcano was made using clay. Strips of clay were plastered in a radial pattern. Then the summit was …

Types of Volcanoes

Polygenetic volcanoes experience multiple eruptions. Composite volcanoes, shield volcanoes, and calderas are polygenetic. As a general rule, polygenetic volcanoes are larger than monogenetic ones. The terms are formed from the prefixes "mono-" (one) and "poly-" (many), and the sufix "-genetic" from the Greek word for origin.

Rocks Lesson #10 | Volcano World | Oregon State University

Rocks Lesson #10. The Earth was formed about 4.6 billion years ago. The planet was so hot that the entire Earth was molten or liquid. As the Earth cooled, the lightest materials floated to the top and the heaviest materials sank to the center. The outer part of the Earth, the crust, consists of the lightest rock.

As lava flows overlap one another, they construct a broad, gently sloping dome shape that from far away appears similar to a warrior's shield. Shield volcanoes build up slowly by the growth of thousands of lava flows that …

Sand Volcano Science Experiment

Erupt your own sand volcano! This simple science experiment for kids is exciting and so easy to do with sand, baking soda, and vinegar.

4 Igneous Processes and Volcanoes – An Introduction to …

When volcanoes erupt explosively, vast amounts of lava, rock, ash, and gases are thrown into the atmosphere. The solid parts, called tephra, settle back to earth and cool into rocks with pyroclastic textures. Pyro, meaning fire, refers to the igneous source of the tephra and clastic refers to the rock fragments.
