Earth & Space
A complete trip of Earth around the Sun takes this long.
What is one year or about 365 days?
Distance from the midpoint to the crest of a wave.
What is amplitude?
This law states that for every action there is an equal and opposite reaction.
What is Newton’s Third Law?
Trait that helps an organism survive and reproduce in its environment.
What is an adaptation?
The two-word naming system for species developed by Linnaeus.
What is binomial nomenclature?
The phase of the Moon when the lit portion is completely facing Earth.
What is a full moon?
Among radio, visible, ultraviolet, and gamma, the one with the highest frequency.
What is gamma?
A 4 kg object accelerates at 2 m/s². Calculate the net force.
What is 8 newtons?
The source of genetic variation that fuels natural selection.
What is mutation?
Level of classification that groups organisms capable of producing fertile offspring.
What is species?
The cause of Earth’s seasons.
What is the tilt of Earth’s axis combined with its revolution around the Sun?
Bending of a wave as it enters a new medium at an angle.
What is refraction?
The tendency of an object to resist a change in motion.
What is inertia?
When humans breed dogs to be smaller or crops to be sweeter, they are using this process that mirrors natural selection.
Humans belong to this order in the class Mammalia.
What is Primates?
Your eclipse investigations showed that a total solar eclipse is visible only where observers stand inside this darkest, cone-shaped part of the Moon’s shadow that reaches Earth’s surface. A:
The part of a longitudinal sound wave where particles are spread apart.
What is a rarefaction?
Friction that must be overcome to start an object moving.
What is static friction?
A well-known bird whose beak shapes on the Galápagos illustrate adaptive radiation.
What are Darwin’s finches?
Kingdom that includes organisms like molds and mushrooms.
What is Fungi?
In the OpenSciEd Earth and Space unit you modeled why regions north of the Arctic Circle can see the Sun for a full 24 hours near the June solstice. That continuous daylight is known by this two-word term.
What is the midnight Sun?
Astronomers use this effect—the apparent change in wave frequency when the source and observer are moving relative to each other—to tell whether a galaxy is coming toward us or moving away.
Two ropes pull a 10 kg sled on frictionless ice: one applies 30 N east, the other 40 N north. Using Newton’s second law, calculate the magnitude of the sled’s acceleration. A:
Natural selection driven by competition for mates—behind features like bright plumage in peacocks—is called this. A:
All modern multicellular animals fall within this domain.
What is Eukarya?
