Name 2 places in WA that are experiencing issues with coastal erosion
Lancelin, Cottesloe
Name the protection that stops waves from removing sand in backwash
Breakwaters
How many degrees would the world's temperature need to increase to give us significant issues?
2-3
What is biodiversity?
The variety of all life in an ecosystem encompassing plants, animals, fungi, and microorganisms
Define sustainability
To be able to live life with the resources provided without using so much that they deplete over time.
Name the two types of waves
Swash (constructive), Backwash (Deconstructive)
Groynes mainly protect against which form of erosion?
Longshore drift
List 3 impacts of climate change
Rising sea levels, lower food production, unpredictable weather, etc.
What are 2 examples of an invasive species?
Relevant answers
List 3 ways people can be more sustainable in their lives?
Use less water, eat responsibly sourced foods, use public transport, etc.
What is the process of longshore drift?
A current that runs along the coast picks up sand and moves it along the coastline.
Name the process that results in sand being picked up and shot or dropped onto beaches
Beach re-nousirhment
What is the Greenhouse effect?
The greenhouse effect is a natural process where certain atmospheric gases, known as greenhouse gases, trap heat from the sun, warming the Earth's surface to a temperature suitable for life
What are 3 drivers of biodiversity loss?
Habitat loss, invasive species, pollution, over-exploitation, climate change
Name 3 cities studied in class that have undergone green initiatives to help improve their sustainability
Vienna, Berlin, Vancouver, Barcelona, Bogata, Seoul, Copenhage, Singapore, Amsterdam
Name the 4 processes of erosion
Abrasion, Attrition, Solution, Hydraulic Action.
Name the location of the longest timber built protection against erosion in the world

By what year is life projected to be radically different if we maintain current trajectories?
What are 2 influencers of biodiversity loss
Human population growth, increasing consumption, inefficient resource use
What are 3 strategies Governments have undertaken to help countries be more sustainable
Paris agreements, solar panel rebates, net-zero targets, switching to renewable energy, etc.
Explain how humans can have an impact on erosion.
Pollution, removal of native vegetation and sand dunes leads to less stable sand meaning it can be removed by processes such as wind or waves can move it easier
What form of protection is the most effective at helping hold sand in place
Sea Wall
