Answers
1
Which of the following processes is a result of meiosis?
asexual reproduction
repair a cut
making new gametes/haploid cells
growing new skin
2
Identify the reproductive process?
sexual reproduction
mitosis
asexual reproduction
meiosis
3
Which describes the relationship between earthquakes and volcanoes?
Volcanic eruptions always cause severe earthquakes.
Earthquakes usually cause volcanoes to erupt.
They are most often located where plates boundaries interact at fault lines
Earthquakes and volcanoes are not related in any way.
4
what is being formed in the image
genes

chromosomes
proteins

When two tectonic plates slip or slide past one another, what type of boundary is it called?
divergent
state
convergent
transform
6
An analogous structure is
embryos that look like; have a common ancestor
Structures useful to ancestors; no longer have a function
Structures that are very similar; came from common ancestor
Structures with similar functions; no common ancestor
7
lithosphere includes what ? Select all that apply
ocean crust
uppermost part of the mantle
continental crust
ocean
8
Is mitosis asexual or sexual?
Sexual
Both
Asexual
Neither
9
A boundary where two plates come together, or collide, is called a
divergent boundary.
transform boundary.
Hot spot
convergent boundary.
10
what will form at this boundary?
volcanic Island Arc & deep sea trench
Continental volcanic Mountains & a deep sea trench
Mid ocean ridge & volcanoes in the ocean
rift valley
11
What does the bracket represent in the image of heredity material?
gene
chromosome
12
The process of individuals having variations that are more suitable for survival and reproduction is known as
resource acquisition
selective breeding
asexual reproduction
natural selection
13
The theory of plate tectonics attempts to explain the
layering of sedimentary rock.
gravitational forces of Earth.
composition of Earth's inner regions.
The mechanism for movement of Earth's upper layers.
14
Convection currents in the mantle begin with...
the core heating up the mantle making it less dense & rising
the core cooling off the mantle making it more dense and sinking
15
Which of the following matches the description: broken into plates
Asthenosphere
Core
Lithosphere
Mantle
16
The similarity in homologous structures suggests
natural selection
a shared common ancestor
selective breeding
co-evolution
17
Which of Wegener's evidences does this image support?
seafloor spreading
Puzzle-like fit (patterns in the geometric shapes of continents)
Forces erode mountains in different locations.
mid-ocean ridges.
18
Which of the following caused the Hawaiian Islands to form?
mid ocean ridges
convergent boundaries of 2 ocean plates
hot spots
subduction zones
19
The lithospheric plates of Earth move due to being dragged along by
Gravity pulling plates in different directions
convection currents in the asthenosphere.
the rotation of Earth on its axis.
the high tides of the oceans.
20
what type of boundary is in the picture?
convergent
divergent
transform
21
what evidence supports that a boundary is convergent
convection currents
subduction zones
earthquakes
mid ocean ridges
22
What does the red dot in the image represent?
Mid ocean ridge
Subduction zone
pressure zone
23
what can happen at divergent boundaries
plates move apart, magma rise, & volcanoes form
plates slide past each other
plates collide and form volcanic mountains
plates stop moving & create a hot spot
24
What is the main cause of speciation?
More offspring are produced than there are resources to support them.
Organisms with beneficial traits tend to survive.
Populations of a species become isolated from one another.
Members of a species can mate and produce fertile offspring
25
Homologous structures have...
different function, similar structure
different structure, similar function
26
How do glaciers provide evidence for pangea?
provide evidence of land bridges forming
provide evidence that global warming causes ice caps to melt
evidence continents with similar groove patterns were joined farther south
they prove that ice ages occurred over the entire Earth
27
destructive plate boundary where the crust is to subduction or crumbled
divergent
transform
convergent
28
Which modern day theory of plate tectonics improved & strengthen Wegener's Continental drift ideas?
glacier grooves in now warm regions
climate evidence of tropical plants in now cold regions
the process of seafloor spreading provided a mechanism for drift
fossil records that correlated
29
Why were scientist skeptical of Wegener's evidence for Continental Drift?
Wegener could not explain how rock layers correlate
Wegener didn't provide evidence of a mechanism/force for his ideas
Wegner did not provide enough fossil evidence
30

crust
lithosphere
outer core
