What caused Pangea to break apart?

mantle convection and movement of tectonic plates

How do ocean floors spread?

occurs at a divergent plate boundary

How do transform boundaries move?

The plates slide past each other

How are tsunamis caused?

by earthquakes below or near the ocean floor

What creates hot spots?

heated magma plumes from the core

How does a volcano form?

earth's plates move, causing magma to come up to the earth's surface

What is convergent boundary?

when two tectonic plates collide together

How are sea mounts formed?

By volcanic activity that builds solidified lava

How does a convection current form?

They are caused by a difference in temperature

What’s a divergent boundary?

When 2 tectonic plates move away from each other

What causes fault lines to move?

Energy is released from a sudden slip of rocks

super hot magma
copper and nickel
iron and nickel
iron and magnesium
2
What is caused by the difference in density in oceanic and continental crust?
mountains
tsunamis
subduction zones
hot spots
3
What caused Pangea to break apart?
tectonic plates creating earthquakes
mantle convection and movement of tectonic plates
tsunamis
hotspots forming
4
How do ocean floors spread?
plates are found with water
sea floors do not spread
subduction zone
occurs at a divergent plate boundary
5
How do transform boundaries move?
The plates get pushed by a giant
They don't move
The plates slide past each other
Plates slide into each other
6
How are tsunamis caused?
because of lightning
by volcanic eruptions in or near the ocean
by ocean tides
by earthquakes below or near the ocean floor
7
What geological features are associated with subduction zones?
rift valleys
volcanic arcs
deep sea trenches
mid ocean ridges
8
What creates hot spots?
burps from the inner core
burps from the outer core.
heated magma plumes from the core
gnomes riding mythical dragons, heating up the crust with their fire breath
9
Is magma found in the Earth's mantle?
False
True
Maybe
Sometimes
10
What causes uplift to occur?
Convergent boundary
Subduction zone
Transform boundary
Divergent boundary
11
How does a volcano form?
volcanoes are formed after a tsunami
they are caused by tornadoes
earth's plates move, causing magma to come up to the earth's surface
they are formed by powerful winds
12
What is convergent boundary?
when a tectonic plate rubs against another plate
when 2 plates move away from each other
when two tectonic plates collide together
when one plate slides beneath the other
13
Where is the Ring of Fire?
Australia
Eurasian plate
Pacific Ocean
Arabian plate
14
How are sea mounts formed?
By water ending up in the same place
By volcanic activity that builds solidified lava
By volcanic activity that uses water and lava to create house
By hot spots creating an island
15
How does a convection current form?
They are caused by cold air
Due to volcano eruptions
They are caused by a difference in temperature
caused by earthquakes
16
How do tectonic plates move?
convection currents
lithosphere cracking
geological atmospheric rotations
water
17
How are trenches formed?
when convergent plates are present
when a plate subducts
when a plate boundary uplifts
when ecosystems are created
18
What’s a divergent boundary?
When 2 tectonic plates move past each other
When 2 tectonic plates move away from each other
When 2 tectonic plates move towards each other
When 2 tectonic plates go beneath each other
19
What causes continental drift?
Rabbits underground
sea floor spreading
conduction currents
climate change
20
Where does magma come from?
Melting of mantle or crust
The solidification of metamorphic rocks
Dirt
Volcano eruptions
21
What causes fault lines to move?
It just happens
Happens because of volcanic activity
The rocks collide and form a line
Energy is released from a sudden slip of rocks
22
What 3 plates have the most continental crust?
Australian, Eurasian, North American
Pacific, Eurasian, Arabian
South American, African, Eurasian
They are all the same
