Section 1

(50 cards)

Total mass of living organisms in a given area.

Front

biomass

Back

movement of Earth's crust

Front

plate tectonics

Back

The shape of the Earth's surface and the way its physical features are arranged; positions and elevations.

Front

topography

Back

Energy of motion (roller coaster increases kinetic energy as it comes down the hill)

Front

kinetic energy

Back

New crust is formed at divergen plate boundaries (sea-floor spreading)

Front

mid-ocean ridge

Back

Rock formed from cooling of magma or lava

Front

igneous

Back

Not allowing to pass through.

Front

insulator

Back

Evidence of a new substance; observed when substances interact such as flammability and rusting.

Front

chemical properties

Back

Energy that is stored (stress in a fault zone, roller coaster at the top of a hill).

Front

potential energy

Back

Relationship between organisms in which one or both benefit.

Front

symbiosis

Back

F = M X A; If an object is acted on by a net force, the change in velocity will be in the direction of the force.

Front

Newton's Second Law of Motion

Back

The tendency of a substance to undergo chemical changes.

Front

reactivity

Back

Genetic trait that is represented with a capital letter and will always show if it is present.

Front

dominant trait

Back

The range of electromagnetic waves placed in a certain order.

Front

electromagnetic spectrum

Back

The measure of an element's ability to combine with other elements, dictated by the number of electrons in the outermost shell.

Front

valence

Back

One or more elements in the same place at the same time, but not chemically combined (like a tossed salad).

Front

mixture

Back

The measure of how tight particles of a substance are packed (mass per volume).

Front

density

Back

Allowing to pass through.

Front

conductor/conductivity

Back

Rivers of hot or cold water within the ocean caused by planet rotation, wind, temperature and salinity.

Front

ocean currents

Back

Genetic makeup; written with symbols (Tt, TT, tt)

Front

genotype

Back

The atmosphere traps solar radiation, because of gases such as CO2, methane and water vapor.

Front

greenhouse effect

Back

More harmful UV rays hit earth due to a gradual decrease of the layer of ozone (upper atmosphere); caused by products using chlorofluorcarbons or cfc's.

Front

ozone depletion

Back

Rock formed under heat and pressure

Front

metamorphic

Back

Physical traits (tall/short)

Front

phenotype

Back

The measure of speed and direction.

Front

velocity

Back

Worldwide climate change mainly due to increase in CO2 levels

Front

global warming

Back

Can be dissolved.

Front

solubility/soluble

Back

Water pressure against a cell wall of a plant cell (firm leaf/wilted leaf)

Front

turgor pressure

Back

Sinking of the Earth's surface (depletion of groundwater/divergen boundary)

Front

land subsidence

Back

Substances moving from areas of greater concentration to areas of less concentration until equilibrium is reached. (examples: heat moves from warmer to cooler areas; gases, nutrients, water moves across a semipermeable membrane)

Front

diffusion

Back

The total amount of force acting on an object (all the individual forces are added together).

Front

net force

Back

The way an organism monitors its needs and maintains equilibrium.

Front

feedback mechanisms

Back

Takes in heat during a chemical reaction, will feel cold (ice pack)

Front

endothermic

Back

Having the same allele for a trait (TT, tt)

Front

homozygous

Back

An objects resistance to a change in motion.

Front

inertia

Back

Rock formed from sediments compacting and cementing

Front

sedimentary

Back

The distance an object travels divided by the time it takes to travel that distance.

Front

average speed

Back

A series of changes in the ecosystem that restores equilibrium over time.

Front

succession

Back

Moving sediment

Front

erosion

Back

Releases heat during a chemcial reaction, will feel warm (decomposition, hand warmers)

Front

exothermic

Back

Force that will cause a change in an objects motion.

Front

unbalanced force

Back

A graph showing the relationship between time and distance.

Front

distance-time graph

Back

Two or more elements chemically combined.

Front

compound

Back

Transfer of thermal energy by movements of a fluid. (convection currents)

Front

convection

Back

Creates soil in primary succession (lichen/moss) first species to appear.

Front

pioneer species

Back

Transfer of energy by electromagnetic waves (light waves)

Front

radiation

Back

What you can observe without the material changing to a new substance (melting, freezing, getting smaller)

Front

physical properties

Back

Molecules expand as more energy is added (alcohol goes up the thermometer showing temperature as heat is added).

Front

thermal expansion

Back

Having both the dominant and recessive allele for a trait (Tt)

Front

heterozygous

Back

The change in an objects speed and/or direction; speeding up slowing down, or change in direction.

Front

acceleration

Back

Section 2

(10 cards)

The variable that you keep the same (no change)

Front

controlled variable

Back

A graph relating the temperature and brightness of stars.

Front

Hertzsprung-Russell (H-R) Diagram

Back

An explanation or model based on observations, experiments, and reasoning, which uses facts to explain and predict natural phenomena.

Front

theory

Back

(also known as the manipulated variable) the variable that you change during an experiment.

Front

independent variable

Back

(also known as the responding variable) the variable that you expect to change as a response to the manipulated variable.

Front

dependent variable

Back

Distance light travels in one year.

Front

light year

Back

For every action there is an equal and opposite reaction.

Front

Newton's Third Law of Motion

Back

A giant structure that contains gas, dust, and billions of stars.

Front

Back

An object at rest will remain at rest unless acted upon by an unbalanced force; an object moving at a constant velocity will remain in the same motion unless acted upon by an unbalanced force.
