Main Revision For EOY Flashcards
Explain the FALL of the British Empire (WW2 & Indian Independence)
After WW2 the British Empire got weaker (no longer the ruler of the world), USA and Russia (USSR) had more nuclear weapons and a larger population than the British Empire.
Indian Independence India was the largest, most profitable British colony, when India gained independence in 1947, they took the population and wealth back and showed others in the empire, they can leave too.
Explain the RISE of the British Empire
The British Empire used naval power and was the first to industrialise.
Explain why the impacts of the Haiti were so bad. (Primary, secondary terms )
Poor infrastructure is one of the main reasons for the catastrophic disaster. Thousands were killed when buildings in the Haitian capital of Port-Au-Prince collapsed.
Primary impacts:
More than 2,000 people died and at least 12,000 were injured. Hospitals, schools and homes were destroyed
Secondary impacts:
social - affects peoples quality of life (transport, health, homes, education)
Economy - affects wealth (jobs)
Political- affects governments decisions
Environmental - affects the natural world (water, land, soil, trees etc)
explain what causes a tsunami to take action ? give an example location that a tsunami has happened in.
earthquakes displace large masses of water, the water is forced upwards and the waves spread out and they get bigger as they get closer to land.
the Indian Ocean Tsunami (2004) and the Japanese Tsunami (2011)
explain the impacts of a tsunami ? ( primary and secondary )
Primary (short term):
- loss of life
- injuries
- damage to buildings and homes
Secondary (long term):
- homelessness
- economic loss
- diseases
- health care ( hospitals )
- education ( schools )
a.what is Constructive (divergent) plate boundaries
b.what is Destructive (convergent) plate boundaries
c.what is Conservative plate boundaries
a.the plates move apart from one another..
b.where the tectonic plates are moving towards each other.
c.where two plates slide past each other
briefly, what caused the earthquake to occur in Haiti
conservative ( convergent ) plate boundaries occurred in the southwest of Port-Au-Prince (capital city) releasing a high amount of energy in the focus to the epicentre causing an earthquake.
Epicentre
the point of the earth’s surface directly (vertically) above the focus of an earthquake
Focus
the point of the Earth’s crust where the earthquake happens.
Can I explain what happens at convergent (destructive) and divergent
(Constructive) boundaries? (Earthquakes and volcano; formation and examples)
Convergent: Usually involves an oceanic plate and a continental plate. The more dense oceanic plate is forced beneath the less dense oceanic plate as they collide. This movement can cause earthquakes and volcanoes. eg. The Pacific Ring of Fire
Divergent: Usually involves two oceanic plates. Plates move apart from one another. When this happens the magma from the mantle rises up to Convergent: Usually involves an oceanic plate and a continental plate. The more dense oceanic plate is forced beneath the less dense oceanic plate as they collide. This movement can cause earthquakes and volcanoes. eg. The Pacific Ring of Fire
Chernobyl,
What caused this disaster to happen?
malfunctioning control rods.
Their role is to slow down the fission reactions by absorbing neutrons, meaning less energy is released.
Chernobyl,
What were the impacts of the disaster?
-radiation was found in food and drink
-animals gained mutations
-the area will not be habitable for 20,000 years
-Pripyat became a ghost town
-around 150 tons of nuclear particles were in the air which spread over Europe and parts of Russia
Explain how nuclear energy can be described as both sustainable and unsustainable (4)
sustainable:
It produces zero carbon emissions and doesn’t produce other noxious greenhouse gases through its operation. This means that the energy is greener
unsustainable:
Nuclear energy produces radioactive waste. These materials can remain radioactive and dangerous to human health for thousands of years.
what is the difference between an Asylum seeker and a refugee
An refugee is a person who has left their country and is seeking protection legally from persecution and serious human rights violations in another country.
An asylum sekker is someone who has been forced to flee conflict or persecution and has crossed an international border illegally to seek safety
What is nuclear power and how is it used to create energy?
Nuclear reactors generate heat, which is removed by a circulating fluid, such as water, and turned into pressurised steam. This steam is then forced through turbines that turn electrical generators to produce electricity.
