What factors make a nation a superpower
Resorces,Military strength,Political power,size,economic strength,Population and soft power
What is a emerging superpower
A powerful country that is near being called a Superpower
What does Bric and Mint represent
Countrys that are emerging Superpowers
What is a Uni-Polar World System
A system where all the power lies in one country
What is a Bi-Polar world system
A system of world order where 2 countrys have the majority of power
What is a Multi-Polar world system
A system where power is distributed across 3 or more countrys
What was the magnitude of the Haiti earthquake
A magnitude 7.0 earthquake
What is Jigsaw fit
Some continents fit together like a geological jigsaw puzzle
What was the original continent called
Pangea
What is continental drift
The idea that continents are slowly shifting theit positions
What are convection currents
Magma is heated to 5000 degrees celcius in the mantle and rises to the crust where they cool and sink only to be heated again. The
process continues. This was powerful enough to move the earth’s plates.
The third piece of evidence Alfred Wegener was The study of fossils.What was it about
Similar fossils are on different continents and the species could not have crossed oceans so they must have lived when the continents where still conected
Alfred Wegener’s forth piece of evidence was Geological patterns.What was this about
Similar pattern of rock lauers on different continents.Coal was also found in Antartica.Coal only formes in warm conditions which means antartica used to be in a warmer part of the world
Who was Alfred Wegener
The man who discovered continental drift
What is the capital city in Haiti
Port au Prince
Which layer of the Earth is the thickest
The mantle
Which layer of the Earth is the hottest
The inner core
Which layer of the Earth is broken up into tectonic plates
The crust
Which layer of the Earth has convection currents
The mantle
Is the inner core of the Earth liquid
No
Divergent(constructive) plate boundaries have the newest rock
True
What happens at a divergent(constructive) plate boundary
A Shield Volcano and Earthquakes
What will happen at a convergent(destructive) plate boundary
A Cone/Composite Volcano and Earthquakes
What will happen at a conservative(transform) plate boundary
Cone/Composite Volcano and Earthquakes
What will happen at a convergent(collision) plate boundary
A Shield Volcano and Fold Mountains
What are the two scales we use to measure earthquakes
The richter scale and the mercalli scale
Which scale measures the magnitude of a earthquake
The richter scale
How does the mercalli scale measure a earthquake
Visual observations to measure the impact of the earthquake
What units are used when measuring a earthquake with the mercalli scale
Roman numerals from I to XII
What is pyroclastic flows
Fast moving currents of hot gas and rock from a volcanic eruption
What is a lahar
Violent type of mud flow or debris flow from a volcanic eruption
Why do people live in volcanic areas
Fertile land for crops
Jobs in tourism
Selling ash
They have no choice
Attractive lanscape
What is the advice given to students in earthquake prome countries
Drop,Cover,Hold on
What are the main cause of earthquakes
Movement of tectonic plates
What are some of the secondary effects of earthquakes
Tsunamis
What does GDP stand for
Gross Domestic Product
Which country is often reffered to as the leading Superpower
The United States of America
What are the 4 layers of the Earth
The crust,The mantle,The inner core and the outer core
What material is the crust usually made of under the oceans
Basalt
Which layer in the Earth is the coldest
The crust
Where is the crust at its thinnest
Under the oceans
What temperature is the mantle
Approximately 1000 degrees celcius neer the crust and 3700 degrees celcius near the outer core
What is the Outer core made of
Semi liquid iron
What temperature is the outer core
3700-5000 degrees celcius
How thick is the outer core
Approximately 2300KM thick
Where is the Earths magnetic field formed
The outer core
How thick is the Inner core
1250KM thick
What temperature is the Inner core
Over 5000 degrees celcius
What materials is the inner core made up of
Mainly iron and nickel
Why are the rocks in the inner core still solid
Because the pressure in the inner core is 4 times more than the crust
What tectonic plate is the UK on
The Eurasian Plate
Where do most earthquakes occur
Tectonic plate boundaries
What is a destructive plate boundary
where two plates are moving towards each other, one of which is continental crust and one is made of oceanic crust
What are fold mountains
large mountain ranges formed by the collision and ‘folding’ of two plates as they plates continually push into one another
What are Ocean trenches
They are deep points in the ocean where the oceanic and continental crust have dragged each other downwards
What are subduction zones
They are when one plate is forced downwards below another plate and grinds past it causing huge amounts of friction and heat
What are more dense Oceanic crust or continental crust
Oceanic crust
What is a Composite Volcano
They are very steep volcanos formed on a destructive boundary.The magma inder the surface has high silica levels and is very explosive which makes Composite Volcanos the most dangerous Volcanos
