Plate Tectonics
What natural disasters helped in mapping plate tectonics
Landslides
Cyclones
Tornadoes
Earthquakes
Earthquakes
What lead to increased technology allowing for increased human population in the past 50yrs
WW2
WW1
The Renaissance
The Cold War
WW2
What is man made earthquakes from?
Landslides from deforestation
Forest fires
Mine shaft Collapse
Bomb testing
Mine shaft Collapse
How does the earth recycle itself
Animals and plants help break it down
Materials are chemically broken down by sea water
The earth keeps adding layers on top making the earth bigger and bigger
Rocks are melted down and float back up to the surface
Rocks are melted down and float back up to the surface
What forms the oceanic ridge
Convergence plates
Volcanic build up
Ocean waves pushing material to the middle
Plate tectonics pulling apart
Plate tectonics pulling apart
What parts of the world normally have higher birth rates
Poorer Countries
Rich countries
Costal countries
Land locked countries
Poorer Countries
Why has earthquakes fatality rate increased
Houses are made from cheap material
Rural areas are getting hit more
Death rates are the same
Greater population density
Greater population density
What cause irelands special rock formations
Gravity
Earthquakes
Plate tectonics
Mining operations
Plate tectonics
What movement dominates dip-slips
Horizontal movement
North to South
Left and Right
Vertical movement
Vertical movement
Where is population concentrated
Cities and Mega Cities
Distributed evenly
More in small Villages
Small cities
Cities and Mega Cities
Why where poor communities faster to rebuild than developed communities
Housing was made from cheaper materials
Cause there’s more poor people
They get the construction companies priority’s
They work harder
Housing was made from cheaper materials
Construction vs Deconstruction and its purpose
Build environments
To reach equilibrium
Destroy old environments and make brand new environments
Recycle the material environments are made of
To reach equilibrium
What kind of force acts on a normal fault
Push
Gravity
Sheer
Pull
Pull
What two demographics have the largest estimated population growth
India and Brazil
China and India
America and Africa
Europe and America
China and India
What was the potato blight an example of? (From class discussions)
Farm output
Carrying capacity
Why crop diversity isn’t required
Invasive species where destroying Ireland
Carrying capacity
What causes different generations of terrain
Dumb luck
Difference in hot spots
Due to inconsistencies
Because oceanic plates and continental plates are different
Due to inconsistencies, it can create different generations
What kind of strike slip fault is it if the right moves towards you
Lateral/dextral fault
Left lateral
Sinistral Fault
Active Fault
Lateral/dextral fault
What is the reason for mortality and fertility rates decrease
They haven’t decreased
Technology has allowed for more people to die
Technology decreases death rate and due to a low death rate, the birth rate naturally falls
Farming has allowed for more kids
Technology decreases death rate and due to a low death rate, the birth rate naturally falls
What is the cause of all natural disasters
Earths internal energy
Plate tectonics
Humans
Just random luck
Earths internal energy
What is isostasy?
When things have equaled out
A buoyancy principle
When two plate tectonics are equal in mass
Explains how the lithosphere is “floating”
A buoyancy principle
