Composite volcano diagram gcse. Composite and shield volcanoes are found along plate margins. There are two main types of volcano - composite and shieldThe two types of volcano form in different places and have very different characteristics. Stratovolcanoes form on the continental side of a subduction zone where the melting oceanic crust forms pools of molten rock in a magma chamber.
Semi molten magma contains seawater and trapped gases which builds pressure 1. There are two main types of volcano - composite and shield. Volcanoes also throw out ash steam dust pumice and gases which can be poisonous.
Students draw and label NT p13 CD and add 2 examples of each country and plate margin. Types of volcano - composite and shield. Volcanoes form when magma reaches the Earths surface causing eruptions of lava and ash.
They produce violent explosions where large ash clouds and pyroclastic flows are present. Escaping ash adds layers to the volcano 1. Task 1 - Using the Google Map below describe the location of the Nevado Del Ruiz volcano.
Annotated diagrams may help you. The volcanic eruptions are often violent with lots of steam gas and ash. Find out about different types of volcano how to measure their strength and preparing for volcanoes.

Synopsis This is a tactile diagram for GCSE students. Shield Volcano Diagram Labeled. The magma molten rock in the magma chamber is lighter than the volcano rocks that.
Composite volcanoes occur at destructive plate margins where plates converge 1. Composite volcanoes are made up of alternating layers of lava and ash. Three huge eruptions have happened in the last 3 million years.
They are usually found at destructive margins. Draw and label a simple diagram of a volcano and the ejected material. A composite volcano is also commonly called a stratovolcano.
Eruptions are infrequent but mostly violent and can include volcanic bombs. Volcanoes vary in shape and structure depending on the reason for their existence. Explain how the.
These volcanoes usually form in subduction zones. 9292011 Students use diagram below to mark 12 volcanoes see list below on world map and label if they are on destructive or constructive plate margins then say if shield or composite. When released the viscous lava travels slowly creating a steep sided volcano.
Composite volcanoes are generally found on destructive plate boundaries. Using this PowerPoint presentation - different types of volcano make a note of each of the four different states of a volcano and the two major types compositestrato and shield. The two types of volcano form in different places and have very different characteristics.
Yellowstone is one example of a supervolcano. This results in. Lava ash cinders and smoke may be ejected from the vent.
The lave has a high silica and gas content and is therefore viscous and explosive. 10112018 Lawa flows out of volcano 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 a a warriors shieldBBC Bitesize - GCSE Geography - Volcanoes - AQA - Revision 4Diagram.
