This is how fast the
plates move every year.
What is 1-12 cm?
These are the two main
types of evidence that
support the hypothesis
of continental drift.
What are the presence
of the same fossils and
rocks on different
continents?
This is when two plates
move together and the
force that causes it.
What is a convergent
plate boundary and
compression?
This is when two plates
move away from each
other and the force
that causes it.
What are a divergent
plate boundary and
tension?
This is when two plates
slide past each other
and the force that
causes it.
What is a transform
boundary and shear?
This is the area where
one plate slides under
another.
What is the subduction
zone?
Convection in the
mantle causes this.
What are the tectonic
plates to move?
These are the two
types of evidence that
scientists have used to
support the theory of
plate tectonics.
What are fossil
evidence and
geological evidence?
This is the hypothesis
that the continents
have slowly moved to
their current locations
.
What is continental drift?
This is the name of the
scientist who first
proposed the
hypothesis of plate
tectonics.
Who is Alfred
Wegener?
These are formed
when layers of lava
and volcanic ash erupt
and build up.
What are volcanoes?
This is formed when
the top of a volcano
collapses down.
What is a caldera?
These are long streams
of molten rock.
What are lava flows?
This type of volcano
has a gentle slope and
is formed from lava
flows.
What is a shield
volcano?
These are locations
where volcanoes form
far from plate
boundaries.
What are hot spots?
This is the process of
changing the
composition of the
rocks and minerals.
What is chemical
weathering?
This is the process of
breaking rock into
small pieces without
changing the
composition of the
rock
What is physical
weathering?
This is what happens
to sediment eroded by
water, ice, and wind
when it slows down or
stops moving.
What is the sediment is
deposited in a new
location?
Sand dunes are and
example of erosion and
deposition by
___________.
What is wind?
Frost wedging is an
example of this type of
weathering.
What is physical
weathering?
This is how long it takes for soil to
form.
What is hundreds to
thousands of years?
This is the type of climate
that soil forms the fastest in.
What are hot and wet
climates?
These are the
components make up
soil.
What are weathered
rock, mineral material,
organic matter, water,
and air.
This is erosion.
What is the process
that moves materials
from place to place?
A rock slowly dissolving in
water and breaking into
different separate elements is
an example of this type of
weathering.
What is chemical
weathering?
