Term
Convergent Boundaries
Definition
The area where two tectonic plates move towards each other. Ex: "Ring of Fire"
Term
Divergent Boundaries
Definition
The area where two tectonic plates move away from eah other. Ex: Mid-Atlantic Ridge
Term
Transform Plate
Definition
Tectonic plates that move along strike-slip faults. Ex: San Andreas Fault
Term
Strike-slip Faults
Definition
Faults that move horizontally.
Term
Pangaea
Definition
The Super-Continent that was made up of the combined continents years ago. It was broken apart by divergent plate movement until the continents drifted to their current locations.
Term
Mountains
Definition
Formed at subduction zones where oceanic plates are pushed into the mantle under continental plates.
Term
Earthquakes
Definition
The result of built up pressure along fault lines caused by roks becoming stuck.
Term
Tsunami
Definition
The result of underwater eathquakes caused by the collision of oceanic plates.
Term
Coriolis Effect
Definition
Creates global wind patterns by deflecting wind through through the Earth's rotation.
Term
Sink Holes
Definition
Formed when too much groundwater is removed from underground.
Term
Igneous Rock
Definition
Rocks formed from cooling lava.
Term
Sedimentary Rock
Definition
Rocks formed from compacted sediments in the ground.
Term
Salinization
Definition
The increase of salt in soil. It can be prevented by more efficently using water during irrigation to limit the salt in it. It can be corrected by removing leaching the salts out of the water.
Term
Indicator Species
Definition
A species used to tell when something is wrong in the environment. Ex: Frogs, Daffodils, Eagles
Term
Keystone Species
Definition
A species that effects all other species in its ecosystem.
Term
Native Species
Definition
A species native to the area it is found in.
Term
Invasive Species
Definition
A species that moves from one are to another. Often disrupts the ecosystem of the area it moves to. Ex: Rabbits in Australia, European Starling and Kudzu in the United States.
Term
Specialist Species
Definition
A species that requires extremely precise conditions in their habitats. More effected by environmental change because they are unable to adapt.
Term
Generalist Species
Definition
A species that has broad requirements for a habitat, allowing it to adapt to most changes.
Term
Biomes
Definition
Areas of the world distinguished by varying climates, plant life and animal life.
Term
Photosynthesis
Definition
The process by which plants use solar energy to convert carbon dioxide into create energy and glucose, while releasing oxygen at the same time.
Term
Chemosynthesis
Definition
The process by which plants convert carbon into organic matter using the oxidation of inorganic molecules or methane as a source of energy.
Term
Producers
Definition
Organisms that produce their own food, almost exclusively plants. Ex: Algae
Term
Consumers
Definition
Organisms that feed on producers for energy. Almost exclusively herbivores. Ex: Plankton
Term
Secondary Consumers
Definition
Consumers who get their energy from consumers on lower trophic levels. Primarily carnivores, but may include omnivores. Ex: Trout
Term
Tertiary Consumers
Definition
Consumers at the top of the food chain. Typically carnivores, but can be omnivores as well. Ex: Great White Shark
Term
Biomass
Definition
The mass of organsms at each trophic level.
Term
Bioaccumulation
Definition
The accumulation of a substance in a single organism. Ex: Tobacco hornworm concentrating nicotine to toxic levels
Term
Biomagnification
Definition
As chemicals and other materials pass through the food chain, it becomes more concentrated in higher trophic levels.
Term
Secondary Succession
Definition
When part of an ecosystem is disturbed, but not completely destroyed, allowing the ecosystem to regrow using what is left from the original. Ex: Forest regrowing after a forest fire
Term
Primary Succession
Definition
New ground, completely devoid of life, slowly begins to create life and a new ecosystem. Ex: Volcanic rock slowly becoming a grassland and than a forest.
Term
Eutrophication
Definition
The process by which a "dead zone" is created in water. Nitrates and phosphorus enter the water through runoff or erosion from fertilizers and creates an algae bloom in the water. This algae than attracts several microorganisms which feed on it and use up the oxygen, killing everything in that area when there is no oxygen left.
Term
Isolation
Definition
When different populations of the same species are seperated for varyin reason, each population begins to develop traits better suited to their new environment. Given enough time, the two populations may even become two seperate species.
Term
Carbon Cycle
Definition
The cycle that carbon goes through regularly. Humans impact this cycle by removing carbon from the earth. Sources of carbon include living organisms and and the carbonates in the ocean. A sink of carbon would be fossil fuels such as coal and petroleum.
Term
Nitrogen Cycle
Definition
The cycle by which nitrogen travels through the Earth. One way humans affect it is by adding excess ntrogen in fertilizers. One example of a source of nitrogen is in the atmosphere. A nitrogen sink are inorganic fertilizers.
Term
Hydrologic Cycle
Definition
The cycle by which water moves. Humans affect it by erecting dams and changing the course of rivers. Sources of water include lakes and streams. An example of a water sink is a dam.
