Tsunamis
Tsunamis are ocean waves triggered by this. Name all 3 for an extra 200 points!
Teacher will need to record extra points if earned.
What is an earthquake or volcano or other movement of ocean floor?
A "sleeping" volcano is known as this.
What is dormant volcano?
Name the 4 layers of the earth.
What is crust, mantle, outer core, inner core?
Cracks between the earth's plates.
What are faults?
A geyser is a hot spring in which water intermittently boils sending this into the air.
What is a tall column of water and steam?
Tsunami means this in Japanese.
What is great harbor wave?
Also known as "tidal wave"
A volcano that is unlikely to ever erupt again is known as this.
What is extinct volcano?
This layer is made of molten or melted iron, minerals and other semi-solid rocks that will still flow under pressure.
What is the mantle?
These plates constantly move and generate pressure which creates cracks on the Earth's surface.
What are tectonic plates?
Hot Springs are formed when water passes through these.
What are cracks in the Earth's surface?
Tsunami waves are only about one meter high in the open ocean. True or False
True - they grow in height near land as the ocean gets shallow
Inside a volcano, it's known as this. When it spills out, it's known as this.
What is magma and what is lava?
Alfred Wegener, a German meteorologist and geophysicist, hypothesized that all continents were once clumped together in a supercontinent known as this.
What is Pangaea?
The large fault that runs through California.
What is San Andreas fault?
Water from the hot spring is heated by this.
What is geothermal heat?
Or
What are hot rocks deep in the crust of the Earth?
This determines how far inland a tsunami can travel.
What is wavelength?
Name the four parts of a volcano.
What is volcanic ash, lava flow, vent, and magma chamber?
Wegener's theory and continental drift theory gave rise to this common day theory.
What is plate tectonics?
Scale used to measure earthquakes.
What is a Richter Scale?
It takes these three things for a geyser to occur.
What is:
abundant supply of water
intense source of heat
unique plumbing
A normal windwave travels at around 90km/hr; a tsunami windwave can travel around this speed.
What is 970km/hr?
Answers close to this are acceptable.
There are 2 main types of volcanos. Name them and give a brief description.
Composite volcanos - cone-shaped with steep slopes
Shield volcanos - wide with gentle slopes
As more observations are made and measurements are collected, scientists revise their theories to be more accurate and consistent with the natural world. A process known as this.
What is the scientific process?
Name 4 of the 5 triggers that are responsible for the destruction of an earthquake.
What are collapse of buildings, landslides, avalanches, volcanic eruptions, and tsunamis
The boiling of pressurized water results in a geyser effect of hot water and steam spraying out of the geyser's surface vent. Another name for this is: (hint another name for geyser)
What is a hydrothermal explosion?
