Metal Ores - 🧠ANSWER ✔✔Mineral rich rocks formed in the earth over
years, metals they release transform into tools
Eastern Pacific Garbage Patch - 🧠ANSWER ✔✔Collection of plastic waste
in the ocean; plastic is swept away into ocean currents around the globe
and accumulate here; plastic is then broken down by the sun's UV rays into
,small particles that sink to the sea floor where they're buried and
transformed into sedimentary rock
Farming - 🧠ANSWER ✔✔The significant activity that prevented predicted
ice ages from forming
Greenhouse Effect - 🧠ANSWER ✔✔Global warming caused by the gases
released from human means
Weathering - 🧠ANSWER ✔✔CO2 in the atmosphere combines to form
snow, carbon goes into the sea and is absorbed by marine creatures which
die & sink to the shore locking the CO2 away, which cools the planet and
contributes to refreezing of the arctic
Pollution - 🧠ANSWER ✔✔Degradation of the environment as a result of
contamination
Acute Pollution - 🧠ANSWER ✔✔Occurs when there is sudden release of
highly poisonous substances within a short time causing complete
devastation of ecosystems, often the release of arsenic/cadmium
Chronic Pollution - 🧠ANSWER ✔✔Occurs when less toxic substances are
released in small amounts over a long period of time causing changes in
, the natural environment, slow amount of substances but they accumulate in
the environment causing long-run cumulative effects
Persistent Pollution - 🧠ANSWER ✔✔Toxic substances do not break down
easily, they become part of the environment and linger for a long time,
causes toxic effects in the body when ingested
Bioaccummulation - 🧠ANSWER ✔✔Occurs when contaminant fields are
built up in the tissues of single organisms of individual species; occurs
when contaminants are passed along the food chain (ex. salmon eats
waste in the ocean, salmon is caught and cooked, human consumes
salmon)
Biomagnification - 🧠ANSWER ✔✔Occurs when contaminants are
transmitted from lower trophic levels to higher trophic levels
Disturbance - 🧠ANSWER ✔✔Physical disruption of the environment
Dematerialization - 🧠ANSWER ✔✔Decline over time in the weight of
materials; calls for waste reduction, recycling, and reuse of materials
Conservation - 🧠ANSWER ✔✔Increasing the efficiency of resource use
