Science Review

What is a volcano?

• A type of cloud formation

• A type of underground cave

• A man-made structure for water storage

• A natural opening in the surface of the Earth where molten rocks, hot gases, smoke, and ash are ejected

What is the classification of an active volcano?

• A volcano that is currently erupting

• Not erupted for the last 10,000 years or more years

• A volcano that has never erupted

• Recorded of eruption within the last 600 years or those that erupted 10,000 years ago

What is the external part of a volcano that may be a crater or a caldera?

• Slope

• Summit

• Magma chamber

• Base

What is viscosity in relation to volcanic material?

• The temperature of the material

• The smell of the material

• The property of the material's resistance to flow

• The color of the material

What type of volcanic eruption is steam-driven and caused by heated water?

• Plinian

• Phreatic or Hydrothermal

• Strombolian

• Vulcanian

What is geothermal energy?

• Energy that comes from the sun

• Energy that comes from wind

• Energy that comes from the heat inside the Earth

• Energy that comes from water

How is geothermal energy generated in power plants?

• By using wind turbines to generate electricity

• By using solar panels to generate electricity

• By using coal to produce steam

• By using the super-hot heat from deep inside the Earth to turn into steam and spin turbines

What are the effects of volcanic eruptions on society?

• Only negative effects

• Only positive effects

• No effects on society

• Destruction, health risks, fertilizer, geothermal energy, and amazing scenery

What is climate?

• The general pattern of weather in a certain area over a long period of time

• The current weather conditions in a specific location

• The study of earthquakes

• The study of clouds

Why do coastal areas have milder weather?

• Large bodies of water absorb heat slowly in the summer and release it slowly in the winter

• They are closer to the equator

• They have more trees

• They have higher altitudes
