Volcanos Suck Major Skata Flashcards
True or false
Some volcanoes erupt quite gently
True
True or false Some volcanoes erupt under the ocean
True
All the lava has the same composition and flows at the same speed
TRUE OR FALSE
False some types of lava have more silicate which determines speed
Volcanoes are most common in the middle of continents
T OR F
False around plate boundaries
Give an example of a famous volcano and its effect
Mt. St. Helensdestroyed forest and wild life around it
Mt Vesuvius buried Pompeii
Explain the two ways that volcanoes form
Hot spots along the earths surface directly above columns of rising magma that’s hot in the stands which creates pressure on the cross I was forced to create volcanoes
Melted crust rises to the surface under pressure
How does God use volcanoes as a tool
They release heat and atmospheric gases which cools the earth
Name three different types of volcanic eruptions and describe them
Icelandic- mild eruption of gas and thin lava through several vents
Hawaiian- mild eruption o gas and thin lava through one cent
Vulcanian-irruption composed of bursts of dark ash and steam and gas
Explain the difference between magma and lava how can scientist tell the difference between my rocks that were made from magma or lava
Magnifies the Neath the surface lava is on the surface. He and pressure of magma changes are rocks love only changes underlying rocks
Explain how formations like devils tower and Sugarloaf mountain were formed
Remaining volcanic tones of magma left after an extinct volcano roads are way round plug of magma
Two things that are used to monitor and predict volcanoes
Seismographs and tilt meters
S-monitors rumblings under the earth
T-observes changes in earths tilt
T or f
A volcano might erupt violently if a plug of magma hardens around a vent
True
True or false
Some volcanoes erupt quite gently
True
True or false Some volcanoes erupt under the ocean
True
All the lava has the same composition and flows at the same speed
TRUE OR FALSE
False some types of lava have more silicate which determines speed
