Fossil, Evolutionary History and Relationships
What does "Extinction" mean?
The permanent disappearance of a species from Earth
A physical characteristic or behavior that allows an organism to survive and reproduce in its environment.
Adaptation
This subatomic particle, with a negative charge, orbits the nucleus.
Electron
Law of Inertia. Object at rest will remain at rest until acted upon. An object in motion will remain in motion unless acted upon.
This property is the measure of the maximum displacement from the equilibrium position and is directly related to the wave's energy.
Amplitude
This is the most common way a fossil is dated by comparing its position in the rock layers to other layers.
Relative Dating
The blending in of an organism with its surroundings, a common survival strategy.
Camouflage
The number of these heavy, neutral particles in an atom can change to create an isotope.
Neutrons
What law is F = MA?
Newton's 2nd law
This phenomenon occurs when two waves combine in the same space, sometimes resulting in a larger wave, or sometimes canceling each other out.
Interference
This type of fossil, like a footprint or burrows, shows evidence of an organism's activity but not the organism itself.
Trace Fossil
The ability of one species to mimic another, often a harmless species looking like a poisonous one.
Mimicry
The total number of protons and neutrons in an atom's nucleus is known by this numerical value.
The mass number
Why does Earth stay in its place in space?
The Sun's pull: The Sun, due to its immense mass, exerts a powerful gravitational force on the Earth, constantly pulling it inward.
This is the term for a wave that can travel through a vacuum, such as light traveling from the sun, because it does not require a physical medium
Electromagnetic wave
A scientist who studies prehistoric life, including fossils, is called this
Paleontologist
The temporary movement of an animal from one region to another in response to seasonal changes in food or climate.
Migration
How does the magnet work on an electromagnet?
You have to have electricity to power the magnetic.
Equal and opposite action and reaction
Newton's 3rd law
A sound wave, which is a longitudinal wave, is made up of these regions of maximum particle density.
Compression
Fossils that are widespread geographically and only existed for a short period of geologic time, making them useful for dating other fossils.
Index Fossil
A state of reduced metabolic activity and body temperature during the winter, which allows some animals to conserve energy
Hibernation
You add more electricity to it
If a bowling ball hits a pin, the force the pin exerts on the bowling ball is equal to the force the ball exerts on the pin, but in this direction.
Opposite direction
The symbol $\lambda$, pronounced 'lambda', represents this distance between consecutive corresponding points on a wave, like from crest to crest
