1
What
provides the force that causes magma to erupt
to the surface?
gravity in the lithosphere
dissolved gases trapped in the magma
the density of the magma
silica in the magma
2
What is the
major cause for the changes in shape and location of the continents and oceans
?
gravity
plate tectonics
Volcanic eruptions
deposition
3
What happens when
diamond
(hardest mineral)
rubs calcite
(lower hardness rating)?
The diamond will scratch the calcite.
Nothing will happen.
It will create a spark.
Calcite will scratch the diamond.
4
What
scale measures the hardness
of a mineral?
Ritcher scale
Moment Magnitude scale
Modified Mercalli scale
Mohs Hardness scale
5
When scientists
use their 5 senses to gather information:
drawing a conclusion
making an observation
making an inference
predicting an outcome
6
The
best unit of measurement for a pencil
is:
6 centimeters
100 centimeters
6 millimeters
1 meter
7
How does
RUNNING or flowing water affect mountains
?
It is a constructive force as it weathers and erodes rock.
It is a constructive force that builds up mountains.
It is a destructive force as it weathers and erodes rock.
It act is a destructive force that builds up the mountain.
8
What is the
independent variable in an experiment
?
variable you change on purpose
variable that responds to the change you made
variable to which nothing is done
variable that you keep the same
9
What determines
how rocks are classified
?
according to their color
According to the minerals present
According to the amount of weathering
According to their origin, or how they formed
10
Variables
that are
kept the same
in an experiment:
hypothesis
controls
constants
conclusions
11
Earthquake waves travel at different speeds through parts of the Earth
because:
erosion of rock layers
how many earthquakes that occur in an area
time of earthquake wave
material that makes up the layer
12
A
rock that has large crystals
was formed:
from lava quickly cooling
from sediments being deposited, compacted and cemented
from magma slowly cooling inside the earth
from other rocks and was changed by heat and pressure
13
Scientists often repeat experiments
multiple times because:
Several trials helps verify the results.
It then turns your hypothesis into a theory.
It allows them to test different variables.
It gives them something to do.
14
Why are
minerals
that are made of the same
elements identified as different minerals
?
They were found in different locations.
Each has different amounts of the elements
They are different sizes.
There is NO difference.
15
How do
tectonic plates interact with eachother
?
Plates can slide past each other.
Plates can pull or move apart from other plates.
They collide, move apart and slip past other plates.
Plates collide with other plates.
16
What
places on Earth are more likely to have earthquakes (and volcanoes)
?
regions in the northern hemisphere
desert regions
big cities
regions where the tectonic plates meet
17
Why is the
sun's energy
important to the
biosphere
?
The sun does not provide energy to the biosphere.
The sun's energy creates water vapor.
The sun provides energy for plants to grow.
The sun's energy heats the inner core of the Earth.
18
The
three main layers of Earth
are:
the rocks, mantle, and the core
the crust, the mantle, and the center
the crust, the ocean, and the core
the crust, the mantle, and the core
19
Which causes the
most change to SOLID Earth
?
ocean currents
the water cycle
atmospheric convection
the rock cycle
20
If a
volcano's magma is high in silica content
, then what
type of eruption
will it have?
quiet eruption
explosive eruption
extinct eruption
oozing eruption
