What is a geologist's job?
Geologists study the Earth.
200
How are magma and lava different?
Lava describes magma that has escaped through a vent, magma is the molten rock under the earth's crust.
200
Name two volcano classifications.
check with host

All of Hawaii's five main volcanoes are what type of volcanoes?
shield volcanoes
300
In the Pacific Ocean, there is a 'ring' of volcanoes. What is this ring called?
the Ring of Fire
300
Describe pyroclastics.
materials blown into the air from a volcanic eruption, not always lava, varying from ashes to cinders to blocks and bombs
300
Name the three benefits of volcanoes.
great rich volcanic soil; heat (steam, hot water) for homes, minerals
300
Name the different types of volcanoes.
shield volcanoes, cinder cones, composite volcanoes, acid cones
300
Describe how volcanoes affect weather and climate.
Ash clouds can lower temperatures for a short amount of time by blocking sunlight, lowering temperatures int he weather, and clouds of sulfuric acid can cover the world and absorbs much of the heat from the sun, lowering climate temperature.
400
Volcanoes form when one tectonic plate pushes on top of another. One of these plates have to be a(n) _______ plate.
an oceanic plate

Name 4 types of pyroclastics.
Ash, Cinders, Blocks, and Bombs

Hawaii's sugarcane depends on the state's good ______.
volcanic soil
400
Describe a shield volcano.
gentle slope, wide area, very liquid lava flows
400
Describe how hot spots affect parks.
They create geysers like Old Faithful in Yellowstone National Park, and other attractions.
500
What is a hot spot?
areas of constant volcanic activity, where the mantle underneath the ground is hotter than other areas
500
Name different formations of lava.
pillow lava, lava tubes, lava cliffs, chunks
500
Name three aftermath destruction formations.
tsunamis, debris avalanches, and landslides
500
How do vulcanologist study and predict eruptions?
1) study lava formations and samples 2) observe past data and historical records 3) study earth vibrations (earthquakes) as these could be a sign of a volcanic eruption 4) observe current volcanic action
