What is the difference between a law and a theory?
Law = scientific observation that is definitely proven to be true
theory = scientific observation that is backed by evidence, but not definitely proven to be true
100
What is the layer of Earth that includes the crust and the outermost part of the mantle?
lithosphere (group 5)
100
What is the name of the plate boundary at which the plates separate?
divergent boundary
100
What do you call an animal or insect that eats plants?
a primary consumer (group 8)
100
What is the difference between a food chain and a food web?
FOOD CHAIN IS ONE SEQUENCE OF ANIMAL DIET AND FOOD WEB IS VARIOUS SEQUENCES OF ANIMAL DIET (more than one food chain combined)
200
What is the difference between objective and subjective?
objective = stating what you see, without bias
subjective = your opinion of your observation
200
Which type of rocks are formed by extreme heat and pressure underground?
metamorphic rocks (group 5)
200
What is the difference between convergent, divergent, and transform plate boundaries?
convergent = plates collide
divergent = plage divise
transform = plates slide past each other horizontally
200
What is a system of interlocking and interdependent food chains?
a food web (group 8)
200
What is the Continental Drift Theory?
The theory that all of the continents used to be one supercontinent called Pangaea.
300
What is the dependent variable?
The observed variable in an experiment that changes are determined by the presence or degree of one or more independent variables.

(from group 1)
300
Which type of rock are these the characteristics of?

fairly easy to break apart, usually contains fossils you can see different kinds of rocks inside rough edged
sedimentary rock (group 5)
300
What are the two types of tectonic plates on our Earth?
continental and oceanic
300
What travels through a food chain or web?
energy (group 7)
300
Name the secondary consumers in this food web.

Is something that is theoretical "possibly true" or "definitely true"?
"possibly true"
400
Which type of rock can change into metamorphic rock?
A. Sedimentary rock
B. igneous rock
C. other metamorphic rocks
D. sedimentary, igneous, AND metamorphic
E. sedimentary and igneous ONLY
D- all 3 types of rocks can change into any other rock, including itself!
400
Name the three arguments that support continental drift theory.
1. Continents fit together like a puzzle.
2. Fossils of the same species found on different continents.
3. Fossils of organisms found in places where they could not have possibly survived.
400
What is the name of the relationship in which both organisms benefit?
mutualism
400
What is the relationship between a flea and a dog?
parasitism
500
What is a limitation of using a scientific model?
Since it is not the same thing, you will not always get the same results as you would in real life.

Explain Carbon Dating.
The process by which scientists study the age of an organic substance by measuring the amount of Carbon-14 left with the amount of Carbon-12 in the material.
500
At which type of plate boundary can a subduction zone occur?
convergent
500
What is the difference between parasitism and predation?
In both parasitism and predation, one organism benefits and one suffers.
Parasitism = one benefits and one is hurt
Predation = a predator hunts and eats its prey; one benefits and the other dies.

Explain the process of photosynthesis using the following words: carbon dioxide, oxygen, glucose, sugar, energy, sun, and water.
In the process of Photosynthesis, plants absorb energy from the sun, water, and carbon dioxide. They create a sugar called glucose, and release oxygen as a byproduct.
