Ecosystems
Name 3 types of renewable resources
Hydroelectric, solar, geothermal, wind,
Salt water accounts for what percentage of all water on earth
97%
These allow the body to grow and repair
Proteins
Law of uniformitarianism
The elements in this have similar chemical properties
Nuclear, petroleum/oil, gas, coal, natural gas
high turbidity
These provide energy
carbohydrates
Law of superposition
Evidence that a chemical change has occurred
(3 minimum)
Color change, production of gas, light emitted, new substance formed, not easily reversed, precipitate formed, rust, burning,
Using non-renewable fossil fuels such as coal and petroleum increases this in the atmosphere
greenhouse gasses
Most of our fresh water on earth is here
Glaciers/ice caps
epidemic
Fossils that are well-known, lived at specific time, and are easily identifiable
Index fossils
Evidence of a physical change (3 minimum)
Color change, size change, shape change, no new substance formed, state of matter change
This type of symbiotic relationship benefits both organisms
Mutualism
Estuaries have this type of water (name and describe)
Brackish
These pathogens have no cells and are not considered living
Viruses
When a rock layer is disturbed by magma. This layer is younger than the layers it pushed through
intrusion
No new matter is created or destroyed, but transferred
Chemical equations have the same amount of atoms on the reactants and products side
Law of conservation of matter
This organism passes a pathogen/disease to a host but does not get sick itself
vector
Water with a lot of phosphate and nitrogen from animal manure and fertilizers can have this
Hint: causes fish kills
Algal blooms
Overuse of this prevents proper treatment of bacterial diseases such as strep throat.
Antibiotic
causes antibiotic resistance
Scientist look at this to determine what past climates were like
Ice cores
This group on the periodic table of elements is the most stable (must tell why)
Group 18, 8 valence electrons
