How do wind and ocean processes relate to ocean currents and gyres?
Wind drives surface currents, while Earth’s rotation and temperature differences shape these into circular systems called gyres.
This interaction is essential for understanding ocean dynamics.
What are the drivers of marine plastic pollution?
- Population growth
- Consumer demand
- Single-use plastics
- Poor waste management
- Industrial production
These factors contribute significantly to the increase in marine plastic waste.
What are the pressures of marine plastic pollution?
- Increased waste entering oceans
- Landfill overflow
- Illegal dumping
- Microplastics spreading through ecosystems
These pressures exacerbate the problem of marine pollution.
What is biodiversity?
The variety of all living organisms in an ecosystem, including plants, animals, and microorganisms.
Biodiversity is crucial for ecosystem health and resilience.
Why is biodiversity important?
It increases ecosystem stability, resilience, and ability to recover from changes or disasters.
Biodiversity supports various ecological processes.
What is species richness?
The number of different species in a specific area.
Species richness is a key component of biodiversity.
Why is species richness important?
More species means stronger ecosystems with better food webs and resilience.
High species richness contributes to ecosystem functionality.
What are the four ecosystem functions?
- Source
- Sink
- Spiritual
- Service
These functions describe the roles ecosystems play in supporting life.
What is a sink?
The ability of ecosystems to absorb, break down, and recycle waste (e.g. carbon storage, nutrient cycling).
Sinks are crucial for maintaining ecological balance.
What is a source?
The supply of natural materials like food, water, timber, and fuel.
Sources are essential for human survival and economic activities.
What is the spiritual function?
The recreational, aesthetic, and cultural value ecosystems provide.
This function highlights the intrinsic value of nature.
What is a service?
Natural processes that support life (e.g. air purification, soil formation, climate regulation).
Services are vital for ecosystem health and human well-being.
What are direct and indirect ecosystem services?
- Direct: resources we use (food, water)
- Indirect: processes that support life (climate, pollination)
Understanding these services helps in conservation efforts.
What are the main spatial patterns?
- Distribution
- Clustering
- Dispersion
These patterns help in understanding ecological and geographical phenomena.
How do you describe spatial patterns?
By explaining where things are located, how they are spread, and any noticeable concentrations.
This description aids in ecological studies.
How do you describe trends with evidence?
Use data, numbers, and comparisons over time to support your observations.
This method is essential for scientific analysis.
What is a trend?
A general direction of change (increasing, decreasing, stable, or fluctuating).
Trends are important for predicting future conditions.
How do you analyze relationships between data?
Compare variables to see if changes in one affect the other (correlation).
This analysis is crucial for understanding complex systems.
What are relationships in data?
Connections between variables (positive, negative, or no relationship).
Identifying these relationships helps in data interpretation.
What are the general impacts of marine plastic pollution?
- Harms wildlife
- Damages ecosystems
- Affects human health and economies
These impacts highlight the urgency of addressing plastic pollution.
What are ecological services?
Benefits ecosystems provide to humans, both direct and indirect.
Recognizing these services is vital for conservation efforts.
What are the 5 oceans?
- Pacific
- Atlantic
- Indian
- Southern
- Arctic
These oceans cover a significant portion of the Earth’s surface.
What are important functions of oceans?
- Climate regulation
- Oxygen production
- Food supply
- Transport of heat and nutrients
Oceans play a critical role in global systems.
What are ocean currents?
Continuous movements of seawater driven by wind, temperature, and salinity.
Understanding currents is essential for navigation and climate studies.
