How many variables can be changed in an experiment
ONE
Which layer of the earth do we live on?
crust
In a layer of rocks, which would be the oldest (top or bottom)
bottom layer is oldest
How do you identify a rock or mineral?
By it's color, hardness, cleavage/fracture, streak, luster or density
Define an independent variable
The independent variable is the condition that you change in an experiment. It is the variable you control. It is called independent because its value does not depend on and is not affected by the state of any other variable in the experiment.
Describe how a metamorphic rock is formed
it breaks down (weathers) into smaller pieces and then is cemented into layers
Which layer of the earth that flows?
mantle
What are the early elements present during the formation of our solar system? Name 2
Helium, hydrogen, ice grains, dust
What is the cleavage/fracture test of a rock?
Pattern that occurs when mineral is broken. Used to identify a rock or mineral
Define controlled variable
factors or variables in an experiment that stay the same. For example, if you took a test- the test would be the control variable because you give it to everyone and it doesn't change
Describe how a rock become a metamorphic rock.
through heat and pressure
List the three types of boundaries
convergent, divergent, and transform.
Define index fossil
widespread fossil known to have lived in a certain time period that is used to date the rock layers in which it is found .
What is the streak test?
Color left behind when rubbing against a streak plate.
What is a dependent variable in an experiment?
The variable in an experiment that changes depending on the circumstances. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.
Describe how igneous rocks are formed
when molten rock cools and solidifies.
List the layers of the earth starting from the inside
inner core, outer core, mantle, upper mantle, crust
List a constructive or destructive Earth process that could affect the environment of Earth's history such as changes to rock layers, land masses, and shapes/structure of land
movement of tectonic plates, weathering, continental glaciation, and volcanic activity.
What does the luster of a rock mean?
How the mineral looks like in the light
Name the 6 steps of the scientific method
problem, research, hypothesis, data collection, analyze data and conclude
When magma cools quickly, what type of rock is formed
igneous
Name 3 land formations that are created by movement along plate boundaries
earthquakes. mountains, oceanic trenches, and volcanoes.
Put the layers of the earth in order from top to bottom
crust, mantle, outer core, inner core
