The process where oil coats feathers, making them heavy and unable to repel water.

Oil on feathers prevents birds from preening, leading to potential ingestion that harms their health.

The process of gathering information to answer a research question, like investigating the best way to clean up oil spills.

Analyzing data collected during a geographical enquiry to reach a conclusion.

A testable statement that predicts the outcome of an experiment or observation.

The act of evaluating the results of a geographical enquiry to determine its strengths and weaknesses.

A systematic method used by geographers to study and understand geographical issues.

Using experiments and observations to collect data about the effectiveness of different oil cleanup methods.

An area in a body of water where there is little to no oxygen, making it difficult for most marine life to survive.

The increase in the size of dead zones in the Gulf of Mexico between 1985 and 2013 was approximately 42.5%.

Intensive farming practices, which involve the use of fertilizers, are the primary source of phosphorus and nitrogen discharged into the Gulf of Mexico.

Excess nutrients, like phosphorus and nitrogen from fertilizers, flow into the Gulf of Mexico, leading to an overgrowth of algae. This algae dies and decomposes, consuming the oxygen in the water, creating a dead zone.

Dead zones can damage coral reefs, leading to coral bleaching and potential ecosystem collapse.

Dead zones can negatively affect tourism by reducing visitor numbers, leading to financial losses for the tourism industry.

Dead zones can damage fishing industries, leading to decreased fish populations and lower catches. This can negatively affect fishermen's livelihoods.

Addressing the problem of dead zones requires measures like treating sewage before discharge, promoting sustainable farming practices to reduce fertilizer use, and encouraging responsible waste management.

Nutrients from untreated sewage cause a rapid growth of algae in coastal waters, leading to oxygen depletion and the creation of dead zones.

Oil spills from tanker accidents or drilling operations contaminate large areas of ocean water, harming marine life and habitats.

Solid waste, especially plastic, enters the ocean, accumulating and posing threats to marine life. It can trap animals or be ingested.

Radioactive materials dumped into the ocean or released from accidents can contaminate marine ecosystems, leading to long-term damage.

Solid waste and pollutants can cause entanglement, suffocation, and poisoning, directly harming marine animals and destroying their natural habitats.

Toxic substances accumulate in marine organisms, moving up the food chain. This can lead to contamination of seafood and human health risks.

Marine pollution can disrupt fishing industries, reduce tourism, and lead to increased medical expenses from seafood poisoning.

Marine pollution can lead to food poisoning and increase medical costs for treating related illnesses.

The process where too many nutrients, like fertilizers, end up in water, causing excessive algal growth.

Areas in a body of water depleted of dissolved oxygen, making it difficult for most marine life to survive.

The process of removing too many fish from a population faster than they can reproduce, potentially leading to its decline.

Microscopic plants that form the base of the food web in aquatic ecosystems.

Microscopic animals that consume phytoplankton and are a food source for larger marine life.

The interconnected feeding relationships among organisms in an ecosystem.

The level in a food web that describes an organism's position based on its feeding habits (producer, consumer, etc.).

The diverse range of living organisms in an environment.

The natural habitats of marine organisms.

The use of chemical fertilizers that contribute to nutrient pollution in coastal waters.
