What is lava
Molten rock that erupts on earth's surface
What produces mudflow?
Volcanic ash and water
Do volcanoes occur on land or underwater?
Both
Where do the deepest earthquakes occur
Where plates collide along convergent plate boundaries
What is magma
Molten rock beneath earth's surface
How fast clouds of hot ash, dust and gases can flow down the slope of a volcano?
What scale measures the intensity of an earthquake?
The Richter scale
Clouds of what can reach the upper atmosphere **Iceland
Volcanic ash and sulfur rich gases
What is a volcano
A mountain built from magma
How does a volcanic eruption affect local communities?
Can cause buildings to collapse, burial of crops, damaged engines, and can cause breathing problems
What is an earthquake
The vibrations in the ground that result from movement along breaks in earth lithosphere
What are the three types of volcanoes
Cinder cones, Shield volcanoes, and Composite volcanoes
What are some things found near a volcano?
Mud flow, Islands, ash, dust and gas
What causes a volcano to erupt
When the pressure of the magma inside becomes so great that it blows open the solid surface of the volcano.
Does ash and gas spread across the planet and reduce sunlight?
Yes
Why do some volcanoes never erupt?
Magma is constantly flowing out of it. So the pressure never builds up and they erupt
Can earthquakes cause faults in earth's lithosphere?
Yes
