Why do scientists use scientific models? (group 8)
It is to understand the world alot easier when it is hard to visualize
100
What is the type of rock that is formed by molten lava cooling? (group 3)
igneous rock
100
What is the name of the plate boundary at which the plates separate?
divergent boundary
100
A system of interlocking and interdependent food chain. (group 8)
What is a food web
100
What is the difference between a food web and a food chain? (group 6)
food chain-the sequence of the transfer of food energy from one organism to another in an ecological community

food web- a system of interlocking food chains
200
What is the definition of empirical (group 1)
definitely proven to be true
200
the solid outer part of earth consisting of the crust and the beginning of the upper mantel (group 3)

A: asthenosphere
B: lithoshpere
C: outer core
D: lower mantle
B: lithosphere
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 photosynthesis (group 6)
photosynthesis is the process through which plants use sunlight, water, and carbon dioxide to create their own food (glucose, a sugar) and oxygen
200
How does the energy flow in a food web and food chain (using the arrows)? (group 6)
if the arrow points to an organism the organism is the one that eats the organism at the other and of the arrow
300
Which three are "possibly true" and which three are "definitely true"? (group 1)

subjective, empirical, observation, objective, theoretical, inference
"possibly true" - subjective, theoretical, and inference
"definitely true" - empirical, observation, objective
300
Which type of rocks are formed by extreme heat and pressure underground?
metamorphic
300
What are the two types of tectonic plates on our Earth?
continental and oceanic
300
What is the difference between producers,consumers,and decomposers? (group 6)
producer is an organism that serves as a source of food for other organisms in a food chain and makes its own energy

consumer is an organism that feeds on other organisms in a food chain

decomposers is an organism, often bacteria or fungi, that breaks down decaying matter to restore nutrients to the ecosystem
300
What is a relationship between two animals where one benefits and one suffers, but the one that suffers does not die. (group 8)
parasitism
400
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
400
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
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
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!
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.
500
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.
500
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.
