Waves
What is a crest?
the highest part of a transverse wave
What is Natural Selection?
This is the process where organisms better adapted to their environment survive and produce more offspring.
What is the change of one type of rock into a new type of rock
metamorphism.
An organism's physical appearance is called this.
phenotype
This is the heat transfer between two objects that touch
CONDUCTION
What is a wavelength?
the distance between crest to crest or trough to trough in a transverse wave or from compression to compression or rarefaction to rarefaction in a compressional wave
What is an adaptation?
Any inherited trait that gives an organism an advantage in its environment is called this.
Aluminum is refined from the common mineral _________?
bauxite
Two different forms of a gene are called this.
alleles
This is the transfer of thermal energy by movement of a liquid or a gas
CONVECTION
What is frequency?
the number of complete waves that pass a given point in a certain amount of time
What are overproduction, competition, variation, and selection?
These are the four requirements for natural selection to occur.
What type of mining uses a rotating drum that travels down a long track while grinding coal?
longwall
This is the term that refers to the physical characteristics that are studied in genetics.
a trait
This is the transfer of energy in the form of waves
RADIATION
What is Hertz?
the unit of measurement for frequency
What is variation?
This is the term for slight differences in the inherited traits of members of a species.
Hard, round structures that form when minerals settle out of water and crystalize around a sand grain or other mineral fragment are called ____________?
concretions
An organism with two different alleles is called this.
a hybrid
This is what we call thermal energy that moves from one substance to another
HEAT
What are types of electromagnetic waves?
Radio waves Infrared waves Visible light waves Ultra violet waves X-Rays Gamma Rays
What is overproduction?
This is the first step of natural selection, where organisms produce more offspring than can survive.
A mineral that remains glowing after being exposed to ultra-violet light and then placed in the dark exhibits
phosphorescence
An organism's genetic type is called this.
a genotype
Sitting in the shade of a tree blocks what type of heat transfer from the sun.
radiation
