What is amplitude?
a) pitch
b) volume
volume
Adelie penguins use physical displays. What is one of displays?
Why do they do that?
Neck thrusts.
To look taller and stronger.
The up-and-down movement of an under-ocean earthquake or a landslide.
Wavelength is measured by _________________.
a) the distance from peak to peak of a waveform.
b) the height from the middle of a waveform to the peak
a) The distance from peak to peak of a waveform.
What do Adelie penguins do that makes us think that they are social birds?
They are constantly communicating.
What makes a tsunami wave powerful?
Their wide wavelengths.
Amplitude (volume) is measured from ____________.
a) the distance from peak to peak of a waveform.
b) the height from the middle of a waveform to the peak
b) the height from the middle of a waveform to the peak
How do kakapo parrots make their low, loud sounds?
They fill up their air sacs and make the sound.
Beside the high speed and wide wavelengths, what else makes tsunami waves so deadly?
It is the shallow water of the coastline that ramps up the waves higher.
A low, loud sound has ___________________.
a) high pitch and low amplitude
b) high amplitude and low pitch
b) high amplitude and low pitch
What starts with T, ends with T, and has T inside it?
a teapot
How do tsnumameters function?
They function by measuring the changes in the water level above them.
True or False:
Both SOUND and LIGHT can be measured by their waveforms.
When Grant was 8, his brother was half his age. Now, Grant is 14. How old is his brother?
His brother is 10.
Half of 8 is 4, so Grant’s brother is 4 years younger. This means when Grant is 14, his brother is still 4 years younger, so he’s 10.
Why are tsunami waves so deadly.
There are two reasons.
Their wide wavelengths and their fast speed.
