What are the three different plate boundaries.
Constructive(divergent) - going away from eachother
destructive(convergent) - going into eachother
conservative - rubbing against eachother
What isnt evidence for plate tectonic theory?
Volcanoes
Define a convection current?
Convection currents are movements in fluids caused by heating. Hot fluid rises because it is less dense, and cool fluid sinks because it is denser. This causes the movement of the tectonic plates.
Explain why earthquakes and volcanoes occur at destructive(convergent) plate boundaries?
Earthquakes and volcanoes occur at destructive (convergent) plate boundaries because two tectonic plates are moving towards each other. One plate is forced under the other in a process called subduction. As the plate sinks, it melts due to the heat, friction and pressure in the mantle, forming magma. This magma can rise to the surface and cause volcanic eruptions. The movement and pressure between the plates also cause high amounts of pressure to release, leading to earthquakes.
Define Epicentre
The point directly above the focus on the earth surface.
define focus
The point where the earthquake happens from underground.
Explain why the impacts from the Haiti earthquake was so devastating?
The impacts of the Haiti earthquake were so devastating because the country was very poor and not well prepared. Many buildings were poorly built and collapsed easily, trapping people inside. The earthquake hit close to the capital city, Port-au-Prince, which was very crowded, so a lot of people were affected. Emergency services were limited and slow to respond, making rescue efforts difficult. Hospitals were damaged, and there was a lack of clean water, food, and medical supplies, which made the situation worse and increased the number of deaths and injuries.
Explain one short term response to the Haiti earthquake?
Refugee camps were set up in the ruined cities to make sure the people werent starving or hurt. They had medical teams for treatment necessary for the people who were badly injured and diseases.
What fact is false about the indian ocean tsunami?
Water moved at 100mph
Explain how an Earthquake triggered the indian ocean tsunami in 2004?
One of the plates subducted under the other causing high amounts of pressure to be trapped. It was then released and formed and earthquake which released a lot of force and displaced the water in the ocean greatly. Creating a Tsunami.
Define a Superpower Nation?
A superpower nation is a country that has the ability to influence events and other countries around the world. This power usually comes from having a strong economy, a powerful military, advanced technology, and global political influence. Superpowers often play a key role in international decisions and can affect global trade, security, and diplomacy.
What are the four MINT nations?
M exico
I ndonesia
N igeria
T urkey
why was britain describe as the empire which the sun never set on?
Britain was described as “the empire on which the sun never sets” because it had colonies and territories all around the world. This meant that at any time of the day, the sun was shining on at least one part of the British Empire. The empire was so large and spread out across different continents that the sun was always above one of its lands.
Explain how the second world war and Indian independence contributed to the fall of the british empire.
The Second World War weakened Britain economically and militarily. The country spent a lot of money and resources fighting the war, leaving it with debts and damage at home. Many people had also died causing them have less workers and military soldiers. After the war, Britain was no longer as powerful and struggled to control its large empire. Many countries in the empire saw Britain’s weakness as a chance to demand independence.
India was the most important and valuable colony in the British Empire. When India gained independence in 1947, it inspired other colonies to fight for their own freedom. Losing India also meant Britain lost a lot of wealth and influence. This made it harder for Britain to keep control over its other colonies, speeding up the empire’s decline.
Asses how IGOs impact global development. You may wish to include: security, trade, the environment, economy and health.
POINTS for Paragraph 1: Positive impacts of IGOs on trade and health
IGOs like the World Trade Organization (WTO) help countries trade fairly by setting rules that reduce tariffs and barriers, which helps economies grow.
The World Health Organization (WHO) supports countries in fighting diseases and improving health services, leading to better global health outcomes.
POINTS for Paragraph 2: Challenges of IGOs in trade and health
Sometimes trade rules favor richer countries, making it harder for poorer nations to compete fairly in global markets.
Health programs led by IGOs may not reach the poorest or most unstable regions, limiting their effectiveness in improving health everywhere.
Describe the locations of the worlds tropical biomes.
Most of the tropical biomes are found on the equator. However some stretch out around the tropics.
What is a consumer.
Something that primarily eats off of vegetations( the first thing that eats something ).
What are decomposers?
Decomposers are living organisms, like bacteria and fungi, that break down dead plants and animals into smaller parts. They help recycle nutrients back into the soil, which plants use to grow.

What are the layers of the Earth?
Crust
Solid, thin outer layer (5–70 km)
Made of rocks (granite and basalt)
Coolest layer
Mantle
Thick, mostly solid but flows slowly
Made of magnesium and iron-rich minerals
Has convection currents
Outer Core
Liquid metal layer (iron and nickel)
Very hot (4,000–6,000°C)
Creates Earth’s magnetic field
Inner Core
Solid metal (iron and nickel)
Extremely hot (5,000–7,000°C)
Solid due to high pressure
What was Wegener’s theory?
Continental drift—continents moved over time. Evidence: fossil fits, jigsaw fit, convection currents, paleomagnetism.
What are tectonic plates?
Large pieces of Earth’s crust that move and cause earthquakes and volcanoes.
Why do earthquakes and volcanoes happen at plate boundaries?
Plates move, interact and subduct, causing earthquakes and allowing magma to escape.
What are convection currents?
Movement of hot and cold mantle material that causes plate movement
