plate tectonics
This outer layer around the planet is broken into many layers and moves around the mantle.
What is the crust (lithosphere)
This is the passing of traits from parents to offspring, a term that also serves as the title of this category.
What is heredity
Because they have only one valence electron that is easily lost, this group of metals is the most reactive on the periodic table.
What are Alkali Metals?
For every action, there is an equal and opposite reaction; this statement defines this specific law of motion.
What is Newton’s Third Law?
This is the only planet in our solar system that rotates on its side, with an axial tilt of 98 degrees.
What is Uranus?
This type of boundary occurs where two plates collide, often creating mountains or trenches.
What is a convergent boundary?
It is the specific genetic makeup of an organism, often represented by two letters.
What is genotype
This term refers to the energy required to remove an electron from an atom, which increases across a period and decreases down a group.
What is Ionization Energy?
While mass remains constant regardless of location, this measure of gravitational force acting on an object changes based on the surrounding gravity.
What is weight?
Formulated by Georges Lemaître and Edwin Hubble, this theory describes the initial expansion of the universe from a hot, dense state.
What is the Big Bang Theory?
Formulated by Alfred Wegener, this theory suggests that all continents were once joined together in a single landmass.
What is Continental Drift (or Pangaea)?
This type of trait is expressed in the phenotype even if only one allele is present in the genotype.
What is dominant trait.
This is the only metal that is in liquid form at standard room temperature.
What is Mercury (Hg)?
This "silent" component of a standing wave on a string—a point where the medium does not move—is the ideal place to touch it without disturbing the wave.
What is a node?
This phenomenon occurs when an object, such as a star, gets too close to a black hole and is stretched into a thin stream of matter.
What is Spaghettification?
This specific type of boundary, such as the San Andreas Fault, occurs where two plates slide past each other horizontally.
What is a transform boundary?
This phenomenon occurs when gene flow decreases between populations but increases within a population.
What is genetic variation?
This law, often associated with Antoine Lavoisier, states that mass is not created or destroyed in a chemical reaction.
What is the Law of Conservation of Mass?
The change in frequency of a wave due to the relative motion between the source and the observer is known by this "Effect" name.
What is the Doppler Effect?
Located roughly 1,000 to 50,000 AU from the Sun, this theoretical spherical shell contains billions of comets.
What is the Oort Cloud?
How do we know that all the continents were once connected?
What is matching rock layers.
This type of cross is used to determine the genotype of an individual with a dominant phenotype by crossing it with a homozygous recessive individual.
What is a test cross?
Specifically named for a Greek deity to represent human gain of new power, this is the first synthetic element to be named, isolated in 1945.
What is Promethium?
his type of friction, which must be overcome to start an object moving, is always greater than the kinetic friction that acts on an object already in motion.
What is static friction?
In 1955, this astronomer (and not Minkowski) found no hydrogen in Type I supernova spectra, identifying them as explosions of white dwarfs.
Who is (Rudolph) Minkowski?".
