100
The three parts of an atom.
Proton, Neutron, Electron
100
What we call any push or pull on an object.
Force

A light wave's frequency is 350hz. How many crests of that wave would enter your eyes in one second?
350
100
Describe natural selection.
Fittest organisms survive longer and reproduce more.
100
This theory explains that the universe began with a rapid expansion.
Big Bang theory
100
100 points for every electromagnetic wave you can name
Question is valid until all of them are named
Radio wave, Microwave, Infrared wave, Visible Light wave, Ultraviolet wave, X-ray, Gamma ray
200
When is an atom neutrally charged?
When it has the same number of protons and neutrons
200
This force pulls objects toward each other and depends on mass and distance.
Gravity
200
The height of a transverse wave, or the density of a longitudinal wave. (These two things use the same word)
Amplitude
200
How can scientists tell that humans and whales (and many other animals) have a common ancestor?
Bone structure (double points for "homologous structures")
200
The name for the theory that says earth's crust moves slowly, causing occasional earthquakes, volcanoes, and other things.
Plate tectonics
200
Two pieces of earth's crust move past each other like walking past someone in the hallway. What kind of boundary is this?
Transform boundary, will also take strike-slip fault
300
The process happening in stars due to the immense pressure of gravity.
Nuclear fusion
300
A heavy object and a light object are pushed with the same force. Of the two, this object will have less change in acceleration.
The heavy object
300
What is the lowest energy electromagnetic wave?
Radio wave
300
You are a scientist and you create the perfect apple seed to grow the perfect apple tree. Using science, you create millions of these seeds for your apple farm. What is this called?
Cloning
300
Two slabs of earth's crust crash together (slowly) and pile up where the collision is happening. What kind of boundary is this?
Convergent
300
Describe the mechanism by which mechanical waves travel.
energy is passed from particle to particle through interactions (forces)
- One particle gets disturbed
- It pushes/pulls on the next one
- That disturbance keeps getting passed along
400
The lightest and most abundant element.
Hydrogen
400
Every action has an equal and opposite reaction. What is the equal and opposite reaction when you fall and hit the ground?
The ground pushes/hits you.
400
A wave enters a new medium. What happens? Looking for the exact word here.
It refracts
400
Why is genetic variation good?
Species that are more prepared for different situations are more resilient.
400
What evidence do scientists have that the universe is expanding?
Galaxies redshifting
400
How are digital signals transmitted to satellites?
Binary wave pulses
500
The two products of the process which happens in stars.
Heavier atoms and Energy
500
What is inertia?
An object in motion will stay in motion until its motion is changed (or stopped) by an outside force.
500
"Surface wave" is the name for the combination between mechanical transverse and longitudinal waves. If you tracked an object following the motion of a surface wave, how would it move?
It goes in circles
500
Describe the entire process of evolution.
Be able to answer questions I have about your answer, I will question you until we have the full story.
A population of the same species exists, with variations. Environment changes. Animals with traits that work well with the new environment survive and reproduce more, and those with traits that do not work well die out. Leftover animals are a little different than the original animal. This process happens many, many, many times.
500
Earth's crust moves because of convection. What is convection?
Hot mantle rises and it creates a circular pattern
500
Describe the life cycle of a plate of ocean crust.
