Name 2 destructive effects of volcanoes that impact people.
- lungs fill with ash - irritates eyes - death - temperature change
100
Name 2 destructive effects of earthquakes that impact people.
- injury to humans - death

Name 1 tool that is used to view changes in temperature.
- thermometer

The lithosphere is broken into many large and small slabs of rock called...
- tectonic plates

What is the epicenter of an earthquake?
- the point on Earth's surface directly above the focus
200
Name 2 destructive effects of volcanoes that impact property/human environments.
- ash clogs engines - ash covers rooftops - sulfuric acid eats away at building materials
200
Name 2 destructive effects of earthquakes that impact property/human environments.
- weakens and shakes foundations - destroys buildings
200
Name 1 tool that is used to measure sulferic gases released from a volcano.
- cospec
200
Name the type of boundary that occurs where plates move apart.
- divergent boundary
200
What is the focus of an earthquake?
- the point underground where rocks first begin to move
300
Name 2 destructive effects of volcanoes that impact wildlife habitats.
- blocks sunlight - lowers temperatures - destroys vegitation - clogs waterways (pyroclastic flows) - mudflows - rockfalls - flashfloods
300
Name 2 destructive effects of earthquakes that impact wildlife habitats.
- alters river/road pathways - alters landscapes and environments - tsunamis
300
Name 1 tool that is used to observe changes in the shape of a volcano.
- tiltmeter - aerial shot
300
Name the type of boundary that occurs where plates push together.
- convergent boundary
300
What type of seismic waves are the first to reach any particular location after an earthquake occurs?
- primary waves (P waves)
400
Name 2 constructive effects of volcanic activity.
- renew the earth and create new landscapes - geothermal energy - hot springs - natural-product (basalt in claening agents) - enriches soil with mineral nutrients - arrowheads of obsidian
400
Name the 3 types of faults that earthquakes occur along.
- normal faults - reverse faults - strike-slip faults
400
Name 2 tools that scientists use to observe bulges in a volcano.
- seismograph - gas meters - lasers - cameras
400
How does the movement of plates at a divergent boundary change the earth's surface?
- mid-ocean ridges and rift valleys are formed as new magma is constantly pushed to the surface
400
When using a seismograph, what does the height of the swiggle waves show?
- swiggles show the amount of energy or magnitude of the earthquake created by the seismic wave
500
Name the 3 different types of volcanoes.
- shield - cinder - composite
500
The shaking of the ground caused by the sudden movement of large blocks of rock along a fault is called...
- an earthquake
500
Scientists communicate their findings to city officials. What might city officials do with this information?
- City officials determine if and when an alert is needed - Possibly if and when to evacuate the population
500
How does the movement of plates at a convergent boundary change the earth's surface?
- more dense oceanic crust moves below the less dense continental crust - coastal mountains and trenches are made when the two plates collide
500
How would the seismograph reading be different if recorded at a town 50 kilometers away from the epicenter, versus the reading recorded at the epicenter?
- the seismographic reading would come at a later time with less intensity in comparison to the reading at the epicenter
