From Rock To Soil
Name one layer of the earth.
Crust, Mantle, Outer Core, Inner Core
Give one example of renewable energy.
Solar, Wind, Hydro, Geothermal, Biomass
What is a primary job?
Farming, fishing, mining, forestry – anything that uses natural resources.
What is GDP per cap
Total money a country makes ÷ number of people = average income per person.
Name one natural hazard.
Earthquake, volcano, tsunami, hurricane, flood, landslide, drought.
What happens at a destructive plate boundary?
Oceanic plate sinks below continental plate, melts in mantle, causes volcanoes and earthquakes.
What does "water stress" mean?
When there isn’t enough clean, usable water to meet demand.
Name two tertiary jobs.
Teacher, doctor, shop worker, bus driver, lawyer...
One development indicator?
Literacy rate, GDP per capita, life expectancy, infant mortality.
Difference between hazard and disaster?
Hazard = potential threat. Disaster = hazard that causes damage.
Difference between 4-figure and 6-figure grid references?
4-figure gives the square area (e.g. 23 45), 6-figure gives a more exact location inside the square (e.g. 234 456).
Two strategies to manage water stress?
Desalination, recycling water, using water meters, building dams, rainwater harvesting.
Clark Fisher Model shows?
How job sectors change over time: primary falls, secondary rises then falls, tertiary rises.
Why is literacy rate important?
Shows education levels, affects job opportunities and quality of life.
How plate boundaries cause earthquakes?
Plates slide or collide → pressure builds → sudden release = earthquake.
Describe chemical weathering with an example.
Rainwater with acid reacts with rock (e.g. limestone) and breaks it down.
Why is renewable energy better?
It’s sustainable, doesn’t run out, reduces pollution, and is better for the environment.
How does globalisation affect where products like iPhones are made?
Designed in USA, parts from Japan/Korea, assembled in China – spreads production worldwide.
What is the development gap?
The difference in wealth and quality of life between rich and poor countries. Example: Qatar vs. Chad.
Two impacts of earthquakes?
Deaths/injuries, buildings collapse, roads damaged, homelessness, disease spread.
Compare two types of weathering.
Physical: freeze-thaw breaks rock. Chemical: acid rain dissolves rock. Biological: roots crack rock.
Challenges of switching to renewable energy in UAE?
Expensive to set up, needs tech, depends on weather, but reduces pollution and saves fossil fuels.
How job sectors change with development?
Poor countries = mostly primary jobs. Rich = mostly tertiary & quaternary. Secondary grows in middle-income countries.
Compare indicators?
GDP shows money, literacy shows education. Literacy is more personal. GDP can hide rich-poor gaps.
Earthquake case study example?
Haiti 2010, Chile 2010, Japan 2011, Nepal 2015, Pakistan 2005, Indonesia 2018, Turkey 2020, New Zealand 2011, Italy 2016, USA 1994...
