the large ocean that surrounded Pangea

What is one way tectonic plate movement affects climate?

creates mountains that affect wind patterns

What is not a piece of evidence Wegener found to support his hypothesis?

tracks of continents plowing through ocean floor rock

According to Wegener, what happened about 2000 million years ago?

The supercontinent began breaking into smaller ones

Wegener's hypothesis of continental drift was finally confirmed by

evidence supporting the idea of sea-floor spreading

Paleomagnetism was key in proving Wegener's hypothesis because

provided evidence of sea-floor spreading

Answers

1
How does sediment that is closer to a mid-ocean ridge compare to the sediment that is farther?
older
larger
smaller
younger
2
Panthalassa was
supercontinent that formed before Pangea
the large ocean that surrounded Pangea
one of the continents that formed from Pangea
a body of water cut into the eastern edge of Pangea
3
What is one way tectonic plate movement affects climate?
keeps ice sheets from melting
changes the location of the equator and poles
keeps air temperatures constant
creates mountains that affect wind patterns
4
The splitting of Pangaea into 2 continents is part of
the process of slab pull
the supercontinent cycle
a convection cell
process of accretion
5
The Himalaya mountains were formed in a collision at a
divergent boundary
transform boundary
fracture zone
convergent boundary
6
A terrane becomes part of a continent in a process called
slab pull
accretion
rifting
converging
7
The theory that explains why and how continents move is called
sea-floor spreading
plate tectonics
paleomagnetism
continental drift
8
Example of a transform boundary
Nazca Plate
San Andreas fault
Eurasia Plate
island arc of Japan
9
The force exerted by the leading edge of a subducting plate is
convection
tectonic plate drag
ridge push
slap pull
10
Frequent earthquakes in an area may indicate
reversed polarity
sea-floor spreading
tectonic plate boundaries
mantle convection
11
Convection, ridge push and slab pull work together to produce
tectonic plate motion
earthquakes
continental lithosphere
fracture zones
12
What is not a piece of evidence Wegener found to support his hypothesis?
debris from Glaciers in South Africa
identical Mesosaurus fossils in South America and Africa
mountains of similar age in North America and Scotland
tracks of continents plowing through ocean floor rock
13
According to Wegener, what happened about 2000 million years ago?
The continents drifted to their present locations
The supercontinent began breaking into smaller ones
the South America and Nazca plates collided
tracks of continents plowing through ocean floor rock
14
What often forms when large terranes and continents collide?
major mountain chains
small coral islands
small volcanic islands
cratons
15
Wegener's hypothesis of continental drift was finally confirmed by
fossils from the same reptile on 2 diff continents
continental coastlines that fit together
the formation of mountain ranges
evidence supporting the idea of sea-floor spreading
16
North America and Eurasia were formed when a rift separated the continent of
Gondwanaland
Pangea
Panthalassa
Laurasia
17
Modern climates are a result of past movement of
heat in Earth's interior
tectonic plates
rain and snow
populations of organisms
18
What is an undersea mountain range that forms at a divergent boundary?
rip
rift
ridge
rent
19
Paleomagnetism was key in proving Wegener's hypothesis because
showed mountains were formed by continental drift
indicated that tropical swamps covered areas that are cold
proved fossils in different places were identical
provided evidence of sea-floor spreading
