Negative Human Impact
The giant patch of plastic waste floating in the North Pacific Ocean
What is the Great Pacific Garbage Patch?
The end result of eutrophication
What is a dead zone?
Coral is this type of factor, while water is an abiotic factor.
What is biotic factor?
Recycling and beach clean up help keep this kind of pollution out of the ocean.
What is trash/plastic?
All of the water on Earth, including oceans, clouds, and rivers, is part of this "sphere."
What is the hydrosphere?
When humans fish too often in a particular place, causing fish populations to rapidly decline
What is overfishing?
Human use of this substance causes eutrophication.
What is fertilizer?
When algae living in coral dies, causing the coral to turn white
What is coral bleaching?
This word means to use natural resources in a way that preserves them for future generations.
What is sustainable?
Humans depend on the ocean for food, resources, recreation, and this.
What is transportation?
Small pieces of plastic no more than 5 mm in size
What are microplastics?
The direct results of too much nutrient pollution in the ocean
The factors that cause coral bleaching (list 2 different answers)
What are stress/excess CO2/acidification AND heat/increased temperatures?
The "three Rs" of sustainable plastic use
What is Reduce, Reuse, Recycle?
When this occurs, fish and other organisms lose their place to live.
What is habitat destruction?
This type of pollution mostly affects organisms who live near the top layers of the ocean since its low density makes it float.
What is an oil spill?
This is the type of human activity that causes the nutrient pollution that leads to eutrophication.
What is agriculture/farming?
The death of this thing is what makes coral "bleach" and turn white.
Human actions to keep the ocean and other ecosystems healthy
What is conservation?
A healthy ocean ecosystem will have more of this.
What is biodiversity?
The Great Pacific Garbage Patch is larger than this large US State.
What is Texas?
When algal blooms block sunlight, aquatic plants cannot produce this substance through photosynthesis.
What is oxygen?
When humans clean and sink manmade objects, such as boats or oil rigs, to provide a new habitat for displaced aquatic life.
What is an artificial reef?
This is the process of turning salt water from the ocean into drinkable fresh water.
What is desalination?
This non-renewable resource found under the ocean is also considered a biotic factor.
What is oil/natural gas?
