What fossil clue supports continental drift?

similar dinosaur fossils found on several continents

What is plate tectonics?

theory of earth split into layers where plates move

What is the idea of continental drift?

continents are constantly, slowly moving over time

Where is the Upper Mantle located?

Both Asthenosphere and Lithosphere

What rock clues support continental drift?

Rocks with similar structures found in USA and Greenland

What is a plant clue to support continental drift?

Glossopteris fossils were found on Africa and South America

How do earthquakes happen?

when 2 plates slide alongside each other

How do mountains form?

convergent boundaries collide and land pushes up

How does seafloor spreading work?

magma to the surface, moves away from ridge, cools & settles

large sections of Earth's layers that move

How do rift valleys form?

2 plates will move apart and land will settle down

What is a strike-slip fault?

fault occurs when 2 plates move alongside each other

Answers

1
What is located in the lithosphere layer?
crust and upper mantle
upper mantle and convection current
crust and core
core and convection current
2
What fossil clue supports continental drift?
similar human remains on different continents
similar dinosaur fossils found on several continents
glacial deposits on various continents
3
What is plate tectonics?
theory where magma creates a series of ridges underwater
theory where earthquakes only occur at valleys and mountains
theory of plates creating the continents
theory of earth split into layers where plates move
4
What is the idea of continental drift?
continents are constantly, slowly moving over time
oceans are sinking and more continental land is revealed
continents were once one, large landmass
oceans were all that existed at the beginning of time
5
Where is the Upper Mantle located?
Asthenosphere
Both Asthenosphere and Lithosphere
Pruosphere
Lithosphere
6
What rock clues support continental drift?
Cliff structures are found in South America and Africa
Rocks with similar structures found in USA and Greenland
Quartz is a rock mineral found worldwide
7
What is the theory of pangaea?
oceans are shrinking
continents were once one land
oceans are slowing making land shrink away
continents coming together
8
What is a divergent boundary?
where 2 plates move together
where 2 plates create a new plate
where 2 plates move apart
where 2 plates move alongside each other
9
What is the name of the sphere where the plates are located?
Prethosphere
Lithosphere
Asthenosphere
Artosphere
10
What is a plant clue to support continental drift?
Glossopteris fossils were found on Africa and South America
Seeds for Marigolds were found on Europe
Fern fossils were found all over the United States land
11
How do earthquakes happen?
when 2 plates stop moving
when mountains are formed
when seafloor spreading occurs
when 2 plates slide alongside each other
12
What is the name of the sphere that allows the plates to move?
Asthenosphere
Thatosphere
Satosphere
Pushosphere
13
How do mountains form?
convergent boundaries collide and land pushes up
transform boundaries slide and cause an earthquake
divergent boundaries separate and land rises up
14
What is a convergent boundary?
where 2 plates slide alongside each other
where 2 plates move apart
where 2 plates come together
when 2 plates create a new plate
15
Which is NOT a fact about Alfred Wegner?
Was Swedish
Gave lecture in 1912 about continental drift
Died in 1930's
Developed idea of Pangaea
16
How did we learn of underwater valleys and ridges?
satellites
sonar
cameras
mineral technology
17
How does seafloor spreading work?
ocean forces magma out of crust & new valley underwater
magma to the surface, moves away from ridge, cools & settles
magma to surface, forms new plate & expands ocean
18
What is located in the Asthenosphere?
Continental Crust
Upper Mantle
Outer Core
Inner Core
19
Who developed the idea of continental drift?
Frank Sinatra
Alfred Wegener
Bill Boothe
Harry Hess
20
What are plates?
small pieces of the continental crust
large sections of Earth's layers that move
portions of the Upper Mantle that collide with the ocean
large sections ocean that create ridges on the seafloor
21
What is true about Alfred Wegener?
He was a paleontologist
He was an Egyptologist
He was a meteorologist
He was a epidemiologist
22
Where is the continental crust located?
Mid-Oceanic Ridge
Lithosphere
Asthenosphere
Pruosphere
23
How do rift valleys form?
2 plates come together to push up land
2 plates will move back and forth but not collide
2 plates will move apart and land will settle down
2 plates will push together to push up magma
24
What is a strike-slip fault?
fault occurs when 2 plates move alongside each other
fault occurs when 2 plates move together
fault occurs when 2 plates move apart
fault occurs when 2 plates collide and make a new plate
25
Who developed the idea of seafloor spreading?
Harry Hess
Bill Boothe
Friedrich Mohs
Alfred Wegener
