(45 cards)
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
