Answers
1
What is absolute age?
none of these answers are correct
the number of years since a rock formed
the age compared to other rocks/layers
It's the number of layers in a rock
2
How minerals are removed from ore deposits?
alternately pouring acids and bases over them
smelting- ore melted to separate mineral from rock
dissolve in water
none of these answers are correct
3
What is an ore?
It is the same as an mineral.
A rock that contains a metal or economically useful mineral
An element that is incredibly economically valuable.
It is the same as an element.
4
What is the dependent variable in the above experiment?
the distance
the design
the trial
the paper (weight)
5
How are metamorphic rocks formed?
Deposition, compaction, and cementation
Forms from the cooling of melted materials
all of these answers are correct
By intense heat and pressure
6
A factor/variable that changes because of the factor/variable that the scientist changed is called the
constant
control
dependent variable
independent variable
7
What is an inference?
information gathered with your five senses
the same thing as a hypothesis
an educated guess based on observations and past experience.
only things that can be measured
8
A trace fossil whos evidence of animal activity
True
False
9
What is an index fossil?
hallow shape of organism
evidence of animal activity (like feces)
Copy of the shape of an organism (the opposite of a mold)
A fossil of an organism that lived a short time & was widely distributed
10
What is accuracy?
how a device gets the same amount each time
closeness to the correct amount or measurement
11
What are the two main ways that minerals form?
Crystallization of secretions from animals
Crystallization of materials dissolved in water
Crystallization of melted materials
They arrive on meteorites.
12
A factor/variable that the scientists can change during an experiment is called
the dependent variable
a constant
the independent variable
the control
13
What's an observation?
an educated guess
something that isn't used in science
information that's collected with your five senses
the same as a hypothesis
14
Determining the order of events and the relative age of rocks by examining the position of rocks in a sequence is called
Law of gravity
Law of rock layers
Law of relative age
Law of superposition
15
What would be a hypothesis for Hank’s experiment?
If weight of the paper is heavier, then the plane will fly farther.
If you throw it farther, it is lighter.
If you throw harder, the plane will go farther.
The plane will fly farther if you throw it better
16
How do you determine density?
mass/volume
you can't
you multiply the mass by the volume
you divide mass by volume
17
Foliated rocks are rocks whose grains form a thin, flat layering effect (banded)
False
True
18
Non-foliated rocks are rocks that have grains arranged in bands
True
False
19
What dating uses the properties of atoms in rocks and other objects to find their ages?
Tinder dating
Absolute dating
Relative aging
Radioactive / Radiometric
20
What does the geologic time scale show?
organisms changed for a while but stopped changing
organisms have become more complex over time
organisms haven't changed since Earth was formed
organisms have become simpler over time
21
What is relative age?
It's the number of layers in a rock
the number of years since a rock formed
none of these answers are correct
the age compared to other rocks/layers
22
What are the characteristics of a mineral?
none of these answers are correct
a clear crystal
the same as a rock
inorganic, solid, crystalline, definite chemical composition, natural
23
What type of scientist studies the solid Earth?
lithologist
geologist
seismologist
GIS Scientist
24
What is the geologic record?
The record of Earth’s history (geologic events and life forms)
the best type of rock album
the full scale of all that has happened since Earth was formed.
The record recorded in rocks of one area
25
A cast is the same thing as a mold.
True
False
26
What is the manipulated variable (Independent) in the above experiment?
The paper (weight)
the design
none of these answers is correct
the toss
27
What is the rock cycle?
A series of processes that changes rocks from one form to another.
The process by which gold is made.
none of these answers is correct
How rocks change in one direction from igneous -metamorphic - sedimentary
28
How is an igneous rock formed?
By intense heat and pressure
Deposition, compaction, and cementation
Forms from the cooling of melted materials
all of these answers are correct
29
What is precision?
how a device gets the same amount each time
closeness to the correct amount or measurement
30
A mold is a hollow shape of an organism.
False
True
31
How is sedimentary rock formed?
By intense heat and pressure
all of these answers are correct
Forms from the cooling of melted materials
Deposition, compaction, and cementation
