Sound
This type of wave requires a medium (Solid, Liquid, or Gas) to travel.
A mechanical wave
The AMOC refers to this major Atlantic Ocean system important for heat transport.
The Atlantic Meridional Overturning Circulation (AMOC)
No sound can travel through this empty space because it needs particles to carry vibrations.
A vacuum
This gas, when absorbed by the ocean, causes ocean acidification.
Carbon dioxide (C02)
Observations indicate AMOC strength has declined roughly this percent from 100%.
85%
Most ocean impacts are connected; this describes how impacts create further consequences across systems.
Cascading effects (They're interconnected)
Sound travels fastest through this dense, rigid material compared with air and water.
Steel
(This is sound)A sound wave has a frequency of 500 Hz and wavelength 0.68m. Calculate speed, show work.
Use speed= frequency x wavelength.
Speed = 500\ \text{Hz}\times 0.68\ \text{m} = 340\ \text{m/s}.
These marine organisms that build shells from calcium carbonate are the most threatened by acidification.
Organisms with calcium Carbonate shells (e.g., oysters, clams, and some types of plankton)
Global sea level has risen by roughly this amount (close to the observed figure given).
(This is Climate systems) A weakened AMOC could make parts of Europe experience this temperature change
Colder temperatures
Frequency (Pitch)
The correct equation that relates speed, frequency, and wavelength.
Speed=frequency x length
Coarl reefs support roughly this share (rounded) of marine species.
About 25%
When evaluating climate actions you should consider these 3 factors together.
Cost, Effectiveness, and Timeline
This process, caused by ocean warming, makes water take up more space and rises sea level.
Thermal expansion
This property (the size of the wave) determines how loud a sound seems.
(Message from me: Mr D added extras so I had to put questions in different categories, this is a sound one) High frequency sound waves are heard as this.
Explain how ocean warming and weakend ocean circulation are connected.
Ocean warming reduces surface water density and changes temperature gradients that drive large-scale circulation like the AMOC; reduced density contrast and added fresh water from melting ice can slow the overturning circulation, which then alters heat transport and regional climates.
Individual actions are useful but this explains their role relative to a larger change.
Important, but not sufficient alone.
Why is it important to consider both individual and systematic climate solutions?
