Small Stuff, Big Bang
This subatomic particle carries a negative charge and "orbits" the nucleus in a system.
electron
According to Newton’s 3rd Law, if a basketball player shoots a basketball, what will the ball do the the player?
equal and opposite reaction
This property of a wave describes the distance between two consecutive crests.
wavelength
This is the primary energy source that drives the movement of Earth’s tectonic plates.
core, (acceptable=convection currents in mantle)
This process describes how individuals with traits better suited to their environment are more likely to survive and reproduce.
natural selection
This process, occurring in the cores of stars, releases massive amounts of energy by joining lighter nuclei into heavier ones.
nuclear fusion
This formula, representing Newton's 2nd Law, shows that an object's acceleration on the mass.
Force = mass x acceleration
Unlike mechanical waves (like sound), these types of waves do not require a medium and can travel through a vacuum.
electromagnetic waves
Alfred Wegener used the distribution of these on different continents as key evidence that the landmasses were once joined.
fossils/landforms
A whale’s flipper and a human’s arm have similar bone structures, which scientists call this type of evidence for common ancestry.
homologous structures
This phenomenon—where light from distant galaxies shifts toward longer wavelengths—provides evidence that the universe is expanding.
redshift?
Gravitational attraction between two objects depends on these two specific factors.
mass and distance
This wave behavior occurs when a wave hits a boundary and bounces back, like an image in a mirror.
reflection
This type of plate boundary occurs where two plates slide past each other, often resulting in large earthquakes but no volcanoes.
transform
This occurs when humans—not nature—choose which organisms to breed based on desired traits, such as in dog breeding or farming.
artificial selection (selective breeding)
These two elements were the primary ones formed during the Big Bang and still make up the majority of the universe’s matter.
hydrogen and helium
It is the force applied to objects that are rubbing against air particles.
drag (or air friction)
Engineers prefer these types of signals (sent as pulses) over analog signals because they are more reliable and less prone to "noise" during transmission.
digital signals (no such thing as a digital wave, just digital langued encoded in those radio waves)
A type of seismic wave that cannot pass through liquids
S-wave
This is the primary "engine" of natural selection; without these random differences in DNA, a population could not adapt to a changing environment.
mutations (genetic variation)
Scientists use this term for the "leftover" heat radiation from the Big Bang that can still be detected throughout the universe today.
Cosmic Background Radiation
Because motion is measured relative to an observer, a person sitting on a moving bus appears stationary to their seatmate but moving to a person on the sidewalk—a concept known as this.
frame of reference (or relative motion)
Causes different colors of light to reach your eye from the setting sun
refraction
A type of plate boundary that will result in subduction and the formation of inland volcanic ranges
convergent boundary
If a mutation causes smaller rabbits to increases in frequency in the population it is know as a..
beneficial mutation
