問題一覧

Vents or openings that expel molten rock or magma from the interior of the earth

Volcano

Magma released into the surface

Lava

The ________ according to the plate tectonics theory is divided into several plates that move above a hot, viscous mantle underneath.

Crust

A mixture of molten and semi-molten rock found beneath the surface of the Earth

Magma

A region around much of the rim of the Pacific Ocean where many volcanic eruptions and earthquakes occur

Pacific ring of fire

This mechanism is evident in the __________ due to the collision of the Pacific plate with several surrounding plates.

Pacific ring of fire

Parts of Volcano

Base, Flank, Summit, Magma reservoir, Conduit, Dike

Outside parts of volcano

Base, Flank, Summit

Inside parts of a volcano

Magma reservoir, Conduit, Dike

The bottom part of a volcano

Base

The top part of a volcano

Summit

The sloped portion of a volcano

Flank

Located beneath the surface of the crust

Magma reservoir

Where the magma reservoir will flow, leads to the crater located at the summit

Conduit

The other path of the magma which lead to the vent located at the flank.

Dike

Magma ejected from these vents often forms the parasitic cones

Dike

There's an opening which may either be a crater or a caldera

Summit

A funnel-shaped opening at the top of a volcano while a caldera is formed when a part of the wall colapses following an explosive eruption

Crater

Volcano with 47 craters

Taal volcano

Primary factors affecting the volcanoes' eruptive style

The magma's temperature, Its chemical composition, The amount of dissolved gases it contains

The property of the material's resistance to flow

Viscosity

The liquid's thickness and stickiness

Viscosity

Types of Volcanic Eruptions

Phreatomagmatic, Strombolian, Vulcanian, Plinian, Phreatic or hydrothermal

A steam-driven eruption as the hot rocks come in contact with water, short-lived, characterized by ash columns but may be an onset of a larger eruption

Phreatic or hydrothermal

A violent eruption due to the contact between water and magma. As a result, a large colum of very fine ash and high-speed and sideway emission of pyroclastics called base surges are observed.

Phreatomagmatic

A periodic weak to violent eruption characterized by fountain lava, just like the Irazu volcano in Costa Rica

Strombolian

Characterized by tall eruption columns that reach up to 20km high with pyroclastic flow and ashfall tephra like that of Paricutin Volcano in Mexico

Vulcanian

Excessively explosive type of eruption of gas and pyroclastics, just like out Pinatubo Volcano in Zambales

Plinian

Classification of Volcanoes according to the shape of their cones

Shield volcanoes, Cinder cones, Composite cones or stratovolcanoes

Are formed by the accumulation of lava that oozes out from the volcano

Shield volcanoes

Are built from ejected lava fragments

Cinder cones

They have a steep slope, wider crater and are the most abundant of the three major volcano types

Cinder cones

Are large, nearly perfect sloped structure formed from alternate solidification of both lava and pyroclastic deposits

Composite cones or stratovolcanoes
