Natural Hazards and Minimizing Damage
Tsunami
What is an extremely large wave.
Molten rock inside the Earth that is about to become lava.
Magma?
What are 2 ways a tsunami can form?
Earthquakes or underwater volcanoes.
Landslide
The sliding rock and soil down a slope.
True or false: A volcanic eruption only affects people a few miles away from the volcano itself.
False: The hot ash/gas cloud can be pushed by the wind and affect areas hundreds/thousands of miles away.
Hurricanes are not only dangerous because of flooding. What are 2 additional hazards that hurricanes can cause?
High winds can damage buildings; storm surges or tsunamis can damage where they first impact the shore.
Give two ways that damage from natural hazards be reduced or prevented.
Build a temporary wall; board up your home; evacuate the area; divert the river or road; preventative brush burns; etc.
Outcome
The result of something
What are at least 2 of the threats created by volcanoes?
Examples: lava, hot ash, gas cloud, flying debris, fire, etc.
How does wave height change as a tsunami approaches land?
The wave slows down and grows bigger
Building a house on stilts is a way to reduce damage from this type of natural hazard?
A flood.
When do earthquakes occur?
Earthquakes occur when plates that were stuck suddenly move (become unstuck).
Drought
An extended period of little to no precipitation in an area.
Volcanoes are often found along the edges of this feature of the Earth.
Tectonic plates.
How do hurricanes begin?
Planting trees along hillsides helps prevent this type of natural hazard.
A landslide.
When plates get stuck, what type of energy do they store?
Potential energy
Avalanche
The sudden sliding of snow, ice, and rock down a slope.
This region in the Pacific Ocean has volcanoes that surround it.
The Ring of Fire.
When an earthquake under the ocean begins to form a tsunami, what direction do the waves move?
They move in all directions away from the source of the earthquake.
