General Science Flashcards
refers to random motion of particles suspended in a liquid or gas– caused by collisions with molecules of the surrounding medium.
Brownian motion
unusually cold temperatures in the ocean waters of the Equatorial Pacific.
La Nina
the earth’s surface directly above the focus
Epicenter
a large mass of water displaced by earthquakes
Tidal Wave
used to detect and record earthquakes
Seismograph
measured in terms of its effects on man: Mercalli scale/Rossi Forrel scale
Intensity
living factors e.g. plant, animals
Biotic Factors
nonliving factors e.g. temperature, sun, air
Abiotic Factors
Primary sources of energy. Organisms that make their own food. (Autotrophs)
Producers
ability of liquid to rise through tubes.
Capillarity
the ability of metals to be drawn into wires.
Ductility
ability of matter to spread quickly; movement of substance from an area of higher concentration to an area of lower concentration.
Diffusion
attraction between UNLIKE molecules.
Adhesion
attraction between LIKE molecules.
Cohesion
temperature at which condensation of water occurs.
Dew Point
unusually warm air water in the Pacific Ocean.
El Nino
Alfred Wegener (1915) Pangaea, the supercontinent, broke into 7 continents.
Continental Drift Theory
The lithosphere is divided into 6 major plates.
Plate Tectonic Theory
The study of earthquakes.
Seismology
place where earthquakes begin.
Focus
feeds on other organisms in order to survive. (Heterotrophs)
Consumers
Primary Consumers
Herbivores
Secondary Consumers
Carnivores
Tertiary Consumers
Omnivores
Animals that feed predominantly on dead plants and animals
Scavengers
Hasten the decay of/and decomposition of animal matter.
Decomposers
Overlapping food chains
Food Web
The transfer of the sun’s energy from producers to consumers as organisms feed on one another is called:
Food Chain
“fixed” form of nitrogen
nitrate ions (NO3-), ammonium ions (NH4+), urea ((NH2)2CO)
ATP (adenosine triphosphate)
major energy provider of the cell.
breaks apart nitrogen molecule (N2)
Nitrogen Fixation
breaks apart nitrogen molecule by microbes; requires ATP.
Biological Fixation
breaks apart nitrogen molecule by lightning; dissolves in rain, forming nitrates.
Atmospheric Fixation
products: ammonia (NH3) and urea ((NH2)2CO) and ammonium nitrate (NH4NH3)
Industrial Fixation
intimate or close association of two organisms of different species
Symbiosis
both organisms benefit
Mutualism
one member benefits while the other is not affected (commensal-host)
Commensalism
one member benefits while the other is harmed (parasite-host)
Parasitism
relationship where one organism attacks, kills and feed on another.
Predation
two or more organism compete or struggle with one another for limited food, water, etc.
Competition
competition between different species
Interspecific competition
competition between the same species
Intraspecific Competition
behavioral adaptation exhibited by the members of a group e.g. ants, bees.
Cooperation
Density
Mass / Volume
Pressure
Force / Area
