Waves
This term refers to the maximum distance a wave vibrates from its rest position; it is essentially the "height" of the wave.
Amplitude
According to Newton’s 3rd Law, for every action force, there is a reaction force that is equal in strength and opposite in this
Direction
These are the preserved remains or traces of organisms that provide evidence of how life has changed over millions of years.
Fossils
This theory explains how Earth's lithospheric plates move slowly over the asthenosphere.
Plate Tectonics
This theory describes the universe beginning as a single point and rapidly expanding roughly 13.8 billion years ago
Big Bang Theory
Unlike mechanical waves (like sound), these waves can travel through the vacuum of empty space.
Electromagnetic Waves
This invisible field’s strength depends on two things: the mass of the objects and the distance between them
Gravity
This is the process where organisms with favorable traits are more likely to survive and reproduce.
Natural Selection
When two continental plates collide, this geographic feature is usually formed.
Mountains
This process, which happens in the core of stars, joins smaller nuclei to form heavier atoms and releases massive energy.
Nuclear Fusion
This phenomenon occurs when a wave bends as it passes from one medium to another, like a straw looking "broken" in a glass of water.
Refraction
If you want to increase the strength of an electromagnet, you can increase the electric current or do this to the wire.
add more coils
When humans choose specific animals or plants to breed for desired traits (like dog breeds), it is called this.
Artificial Selection (or Selective Breeding)
This type of boundary occurs where two plates slide past each other horizontally, often causing earthquakes.
Transform Boundary
When astronomers see light from a galaxy shifting toward this end of the spectrum, it proves the galaxy is moving away from us.
Redshift
Scientists prefer using these types of signals for long-distance communication because they are more reliable and less prone to "noise" than analog signals.
Digitized (or Digital) Signals
This is the sum of all forces acting on an object; if it is zero, the object's motion will not change
Net Force
DAILY DOUBLE: Scientists compare these "leftover" anatomical structures, like a whale's pelvic bone, to show evidence of a common ancestor.
Vestigial Structures
This device is used by scientists to measure and record the vibrations (seismic waves) produced by an earthquake
Seismograph
This subatomic particle has a positive charge and is located inside the nucleus
Proton
To find the speed of a wave, you must multiply these two properties together.
Wavelength and Frequency
Newton’s 2nd Law is often expressed with this mathematical formula.
F = ma (Force = Mass x Acceleration)
These structures do not suggest common ancestry
Analogous Structures
The "Ring of Fire" is a major area in the basin of the Pacific Ocean where a large number of these two events occur.
Earthquakes and Volcanic Eruptions
These two elements were the very first to form in the early universe and still make up most of its matter
Hydrogen and Helium
