TYPES OF VOLCANOES

It is refers to an opening or vent in the planets’ crust from which the molten rock, ash (pulverized rock and pumice), gases escape from below.

What is Cinder Cone volcano?

• Steam-driven eruption as the hot rocks come in contact with water. It is short- lived, characterized by ash columns but may be an onset of a larger eruption.

  This what happened in Taal.

• The lava that comes from this kind of mountain is thin and they are prone to travel for long distances. These volcanoes can build up over the years to form mountains. They sometimes explode when erupting

• simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone. Most cinder cones have a bowl-shaped crater at the summit and rarely rise more than a thousand feet or so above their surroundings.

• This is Large and tall. Neary perfectly slope;

  Formed from the alternate solidification of lava and other pyroclastic materials.

Which of the following analogy is TRUE about the volcanic shape and its description?

• Shield: smallest

• Caldera: largest

• Cinder: smallest

• Composite: largest

aal volcano erupted in the year 1965 due to contact of water and hot rocks. How can this volcanic eruption be classified?

• Phreatic

• Plinian

• Vulcanian

• Phreamagmatic

Which of the following analogy is correct about volcanic eruptions and its cause?

• phreatic: hot rock and magma

• phreatomagmatic: magma and water

How magma differs with lava?

• Magma are ejected by the volcano and Lava are inside the volcano

• magma is composed of molten rock and is stored in the Earth’s crust, while lava is the magma that reaches the surface of Earth through a volcano vent.

• Magma is same as lava.

• Both magma and lava are earth materials.
