Volcanoes 1
What is the dust and ash coming out of the tops of volcanoes called?
What is an ash cloud.
It is where magma is found in a volcano
What is the magma chamber?
It is a type of volcanic eruption that results from the thermal contraction of magma when it interacts with water.
What is a Phreatomagmatic eruption
Name 3 of the different types of volcanoes.
What is Shield Volcano, Composite Volcano, and Cinder Cone Volcanoes.
Also: lava plateaus, caldera (types of volcanic landforms)
_________ is a molten mixture of rock-forming substances, gases and water from the mantle; when it reaches Earth’s surface it is called lava
What is magma.
________ is a huge hole left by a collapse of a volcano.
What is caldera.
These are destructive effects of a volcanic eruption
What is destroying animal habitats, destroying cities and communities, destroying animals, crops and people.
What are some constructive effects of volcanoes?
What causes volcanoes?
What is when fractures in the Earth's crust allow magma to reach the surface.
A ________ is a weak spot in Earth's crust where molten material, or magma, comes to the surface.
What is volcano.
It is the strongest volcanic eruption which is a result of an extreme build-up of gasses in the magma chamber. An example of this volcanic eruption is the 1991 Mt. Pinatubo eruption.
What is Plinian eruption.
_________ is molten rock on Earth's surface.
What is lava.
Fractures in Earth's crust allow magma to reach the surface causing ___________.
What are volcanoes.
The _____________ is a volcanic belt consisting of volcanoes and earthquakes located at the rim of the pacific boundary, caused by the diverging and converging of plates in that area.
What is The Ring of Fire.
At plate boundaries, the crust often fractures due to diverging or converging plates. Converging plates create ___________.
What are subduction zones.
A __________ volcano is tall and formed of alternating layers of ash and lava; shoots out lava and rock fragments, forming a high, towering mountain.
What is composite.
The Binintiang malaki is an example of this type of volcanoe.
Cinder cone Volcano
An ________ volcano is not likely to erupt again.
What is extinct.
A ________ volcano is where lava flows out freely from a vent, building a wide, gently sloping mountain.
What is shield volcano.
An __________ is a string of islands created by volcanoes near boundaries where two oceanic plates collide and one sinks beneath the other.
What is island arc.
A _________ volcano's lava has high viscosity and produces ash, cinders and bombs that build up a steep hill.
What is cinder cone volcano.
A _______ _________ is when magma with trapped gasses build up pressure and explode with incredible force.
What is explosive eruption.
A ______ ______ is an area where material from deep within the mantle rises then melts, possibly forming a volcano where magma erupts through the crust.
What is hot spot.
A ________ _________ is when magma flows easily with gasses bubbling out gently and quietly.
What is Effusive eruption.
eruptions that are a result of clumps of gas bubbles at the surface, throwing uo clots of lava. Has high concentration of pyroclastic debris
What is strombolian eruption?
