What geological process formed this mountain range?

two continental plates converging

The process occurring in the mantle that is thought to be the force behind plate tectonics is

convection currents in the mantle

Which claim is supported by the diagram?

Mass and distance of an object affects gravitational force

In what way are volcanoes constructive processes?

new igneous rock is formed or created when magma solidifies

As these two people approach the end of the pier, their gravitational potential energy will

increase because the height increases

If this is a hotspot, what causes it?

A stationary plume of magma melting through the moving plate

Which two pieces of evidence were strongest for Alfred Wegener for Continental Drift?

Fossils of like species found on opposing continents, Mountain ranges ages match up across the ocean

In the pedigree, Is this a dominant or recessive trait being traced?

Dominant because the trait appears in every generation

Which would require the least amount of force of a ball on a flat smooth surface?

keeping the ball in motion at a constant speed

What conclusion can you draw about tectonic movement in the illustration below?

Plates diverged slowly, a rift formed then filled with H2O.

Questions 21

Answers

1
What is the contour interval of this map?
greater than 125
25
125
there isn't one
2
What geological process formed this mountain range?
an earthquake in a subduction zone
two continental plates converging
a tectonic plate moving over a hotspot
movement at a transform boundary
3
The process occurring in the mantle that is thought to be the force behind plate tectonics is
uplift of the layers of rock
strong winds and ocean currents
convection currents in the mantle
P waves and S waves
4
Which claim is supported by the diagram?
Mass and distance of an object affects gravitational force
As gravity decreases distance increases
Planets that are smaller have more gravity.
Gravity is a force that is affected by the shape of objects.
5
What data was used to determine the makeup of the interior of the earth?
How seismic waves are picked up at worldly seismic stations
The measurement of seismic waves using seismographs
Analysis of wave behavior and travel times
All of the above
6
Where is Gravitational potential energy the greatest?
Falling off the tree
on the ground
while falling
7
In what way are volcanoes constructive processes?
They are very hot and melt granite to make counter tops.
new igneous rock is formed or created when magma solidifies
Volcanoes destroy everything, they aren't constructive ever
8
As these two people approach the end of the pier, their gravitational potential energy will
remain the same because their mass stays the same
never change because of the water below
increase because the height increases
decrease because the height increases
9
What land features might form at Point A?
a volcanoe
all of the above
a mid oceanic ridge
A rift like in AFrica or Iceland
10
Predict the outcome of two oceanic plates converging.
possible volcano formation
formation of a deep trench
all of the above
Island Arcs
11
If this is a hotspot, what causes it?
A stationary plume of magma melting through the moving plate
A moving piece of magma that follows the pacific plate
volcanoes in the ocean that make new crust
the convection currents in the outer core and thermal heat
12
Which two pieces of evidence were strongest for Alfred Wegener for Continental Drift?
Fossils of like species found on opposing continents
the shapes of the continents fit like a puzzle
Mountain ranges ages match up across the ocean
The sea floor spread and made magnetic reversals
13
What feature is most likely to form at a mid-ocean ridge?
Volcano
Plateau
Delta
Peninsula
14
If there were a flash flood, which side would be affected the quickest?
The south side
the north side
The east side
The west side
15
In the pedigree, Is this a dominant or recessive trait being traced?
Dominant because the trait appears in every generation
Recessive because there are no carriers
Dominant because it is in both males and females.
Recessive because it is in mostly females
16
What is the difference between continental drift and plate tectonics?
Evidences from Continental drift are used in Tectonic Theory
Continents themselves do not move, the plates move
Tectonics uses the fact of sea floor spreading to explain
all of the above
17
How do natural events illustrate plate tectonic movement?
all of the above
Earthquakes -measurable movement of the plates
Volcano formation is slow and magma rises from the mantle
Deep ocean trenches form when more dense plates subduct
18
Which shows the relationship between the GPE of an object/ the object’s height above Earth?
3
4
2
1
19
Which would require the least amount of force of a ball on a flat smooth surface?
start the ball in motion
Changing the direction of the ball rolling
Stopping the ball that is rolling on a flat smooth surface
keeping the ball in motion at a constant speed
20
What conclusion can you draw about tectonic movement in the illustration below?
Convergent boundaries met and volcanoes formed
Erosion occurred and a lake formed
Plates diverged slowly, a rift formed then filled with H2O.
Plate tectonics would not cause this to happen.
21
As you are riding in a car down the road, how do the light poles appear to move?
backward
they are stationary and do not appear to move
in the same direction as you
forward
