Food production
Which climate region in Asia is especially suitable for rice farming because of heavy rainfall?
The monsoon climate region.
What are natural resources?
Materials and resources from nature that people use.
Name three renewable energy sources.
Examples: solar, wind, hydroelectric, geothermal, biomass.
Name four different modes of transportation.
Examples: road, railway, air, water, pipeline, information traffic.
Which Mediterranean region product is especially important: olives, rice, or bananas?
Olives.
Name three of the world’s most important food plants.
Examples: rice, wheat, maize (corn), potatoes, soybeans.
What is the difference between renewable and non-renewable resources? Give examples.
Renewable = can replace naturally (solar, forests).
Non-renewable = limited and form very slowly (coal, oil).
Name three fossil fuels.
Coal, oil, and natural gas.
What are two advantages of railway transportation?
Examples: energy efficient, environmentally friendly (no CO2 emissions), good for large numbers of passengers or heavy cargo.
Which fossil fuel is often used for heating and electricity production and produces less pollution than coal?
Natural gas.
What kind of conditions are best for farming in the temperate grassland region?
Fertile soil, moderate temperatures, and large flat areas suitable for crops like wheat.
Name the three main rock types.
Igneous, sedimentary, and metamorphic rocks.
Advantages and disadvantages of nuclear energy?
+ Releases a lot of energy.
+ Nuclear power plants produce a reliable output because they are not affected by the weather or time of day.
+ Nuclear power stations do not release carbon dioxide or sulfur dioxide.
+ Nuclear power plants are not restricted by location.
- Mining uranium/plutonium/nuclear fuels causes habitats to be destroyed.
- Nuclear power stations produce radioactive/hazardous waste that has to be stored safely for centuries.
- An explosion in a nuclear reactor would release radioactive material over a wide area, which would affect the organisms living there for many years.
- Power station use non-renewable energy resources.
We get energy by splitting uranium atoms (nuclear fission), which releases heat to produce electricity.
When is water transportation the best option?
For heavy, large, and international cargo over long distances, when speed is not the most important factor.

Give two problems related to animal farming.
Examples: greenhouse gas emissions, deforestation, animal welfare issues, high water use, pollution.
What are ecosystem services? Give four examples.
Benefits humans get from nature. Examples: food production (berries, mushrooms, game animals...), wood, medicines, clean water, pollination, climate regulation (carbon sinks + produce oxygen/sugar), recreation.
Which energy resources are powered directly or indirectly by the Sun? Mention at least 4.
Solar, wind, hydroelectric power, wave energy, biomass, and fossil fuels (because ancient plants used sunlight).
Compare air transportation and road transportation. Give one advantage and one disadvantage of each.
Air: Fast, but expensive and polluting.
Road: Flexible – door-to-door service without fixed schedules, cost-effective – For short and medium distances, generally cheaper than air or rail travel, roads reach almost every location. Overcrowding on roads, environmental pollution, high accident risk.
Why are tropical rainforest regions difficult for farming in some areas even though it rains a lot and there is warm year around?
Because soil is often poor and nutrients wash away quickly.
Why should we use more biofuels, and what are two disadvantages of them?
Advantages: reduce fossil fuel use, renewable source, can reduce carbon emissions.
Disadvantages: take farmland away from food production, may cause deforestation, can be expensive.
When rocks break into smaller pieces, what useful materials can form, and where are they used?
Sand, gravel, and clay can form. Used in construction, roads, buildings, glass, and ceramics.
What energy source should Qatar use more, and which should it use less? Justify your answer.
Qatar should use more solar energy because there is plenty of sunshine or wind energy because it's location (surrounded by sea areas). Qatar should depend less on fossil fuels (natural gas/oil), because they create greenhouse gas emissions and are non-renewable.
What is pipeline transportation? Mention 2 advantages and 2 disadvantages of it.
Pipeline Transport (Oil, gas, water pipelines):
+ Energy-efficient for liquids & gases
+ Low operating costs after construction
+ Continuous, reliable transport (24/7)
+ Low emissions during use
+ Safe for transporting large volumes (oil, gas, water)
- Expensive to build
- Limited to liquids and gases only
- Leak risks can cause serious environmental damage Inflexible – fixed routes
- Construction can damage natural habitats
Imagine Qatar wants to become more sustainable. Name two transportation changes and two energy changes that could help.
Transportation: better public transport, more electric vehicles, cycling routes.
Energy: more solar power, less fossil fuel use, energy-efficient buildings.
