What is a seismic wave?
A wave produced by and earthquake.
100
What kind of wave is a tsunami?
Surface wave
100
What happens to the wavelength of a tsunami as it approaches land?
Wavelength gets smaller
100
Name 2 ways that a tsunami could hurt our environment.
It could wipe out ecosystems, and could knock down trees\kill plants
100
What is the difference between qualitative and quantitative?
Qualitative: Observing with your senses Quantitative: Observing numbers
200
What type of seismic wave is a Primary wave?
A longitudinal wave
200
How is the surface wave that is the tsunami caused?
An underwater earthquake (plates colliding)
200
What happens to the amplitude of a tsunami as it approaches land?
Amlitude increases
200
Name two ways that tsunamis can effect humans (us)
Tsunamis can kill us, they can also destroy our homes
200
What is the scientific method (in order)
1. Question 2. Research 3. Hypothesis 4. Test\Experiment 5.Conclusion
300
What type of seismic wave is a secondary wave
A seismic transverse wave
300
Name three disturbances that can cause a tsunami.
Colliding plates, Earthquakes, Eruping Volcanoes
300
What happens to the speed of a tsunami as it approaches land?
It goes slower
300
The effect of a volcano erupting can be:
Disturbing water and forming a surface wave, that became a tsunami.
300
What is a medium?
A material that a wave can travel through
400
What kind of seismic wave travels the fastest?
Primary wave (or seismic longitudinal wave)
400
How do Tsunamis produce sound?
They transfer energy from the water to the ground to the air, disturbing the air molecules, forming longitudinal sound waves, that reach peoples ears as sound.
400
Name one sign that a tsunami is coming.
The sea starts to pull back
400
The effect of a tsunami crashing and transfering energy to the ground and into the air is:
It will make sound
400
Name a type of wave that doesnt require a medium to travel through
Electromagnetic waves ( Sun waves, ect.)
500
What is the most destructive and powerful type of seismic wave?
Surface wave
500
How does the transfer of energy occur from seismic waves, to tsunamis, to sound waves.
Volcanoes\Earthquakes make seismic waves that transefer their energy to the water making a surface wave that becomes a tsunami, and the tsunami transfers it ernergy from the water to the ground, then right back up to the air, and logitudinal waves form, reaching ears as sound.
500
What is the medium that carries a seismic wave?
Earth
500
After plates collide, describe the effects of the underwater earthquake.
After the underwater earthquake, water is disturbed a nd a surface wave is formed, and that large surface wave forms a massivly destructive tsunami
500
What is a line graph used for?
To show change over time
