Natural Hazards
An example of a weather related hazard
Which type of volcano forms in the center of a tectonic plate?
Hot spot volcano
The point where movement occurred which triggered an earthquake is called what.
Focus
What is an opening in the Earth's surface through which lava, volcanic ash, and gases escape.
Volcano
These 2 types of waves are located on the surface of the Earth during a seismic event.
Love and Rayleigh waves
A naturally occurring event that can potentially have a negative effect on humans
Natural Hazard
This type of volcano get their gentle hill-like shape because they are built of successive flows of low-viscosity basaltic lava
Shield volcano
The location where earthquakes are found is called
Fault
Where do continental arc volcanoes form?
Subduction zones
These types of seismic waves are fast and move through both solids and liquids.
P waves
Landslides, tsunamis and volcanic eruptions are all examples of what?
Geological hazards
These types of volcanoes are relatively small, steep, cone-shaped hills made up mostly of partly burned ash and lava cinders.
Cinder volcano
The study of earthquakes, its movements and it's effects is called
Seismology
This part of a volcano is where magma rises through to the main vent.
Conduit
These waves move in a side to side motion in the direction of the wave.
Love waves
When does a natural hazard become a disaster?
When its results include damage to property and/or death.
These types of volcanoes are also known as stratovolcanoes, are steep-sided, symmetrical cones formed when pyroclastic eruptions (explosions of ash, cinders, and rock fragments) alternate with lava flows and layers build up over time.
Composite volcano
When two tectonic plates move away from each other, this produces which type of stress on the Earth's crust?
Tension
This is where magma is stored in a volcano
Magma chamber
These type of seismic waves move through solids only.
S waves
When scientists predict natural hazards, they look at location, time, duration, magnitude and what?
Frequency
These types of volcanoes are formed when very thick lava erupts through the volcano’s vent and then piles up around it.
Lava domes
When two tectonic plates move side by side from each other, this produces which type of stress on the Earth's crust?
Shear or shearing
This describes how runny the magma or lava is
Viscosity
Which type of seismic waves travel in a circular motion.
Rayleigh waves
