FOSSIL FUELS FORMATION
Name three examples of fossil fuels.
Coal, oil, and natural gas.
Name three renewable energy sources.
Solar power, wind power, hydroelectric power,geothermal, wave, tidal .
Which element is most commonly used as fuel in nuclear reactors?
Uranium
What are two causes of oil pollution in marine and coastal ecosystems?
Offshore oil extraction and oil spills from ships
What does renewable energy mean?
What is energy from natural sources that are constantly replenished, like sunlight, wind, or water?
Why are fossil fuels considered non-renewable?
Because they take millions of years to form and are consumed faster than they are replaced.
Which energy source uses underground heat?
Geothermal energy.
What harmful type of emission is produced during nuclear reactions and can cause serious health problems
Radioactive radiation
Clean up operations are:
Using Booms, detergents and Skimmers .-
What is fracking and how does it extract oil or gas?
Method of extracting oil or gas by injecting high-pressure fluids to fracture underground rocks?
What type of pollution is caused by burning coal?
Air pollution, especially carbon dioxide and sulfur dioxide emissions.
What is a disadvantage of wind power?
It depends on weather conditions and can be noisy or affect bird migration.
What is one positive benefit of nuclear energy compared to fossil fuels?
Producing large amounts of electricity with low greenhouse gas emissions - No air pollution -
Name two impacts of oil pollution on marine ecosystems.
Harm to marine life and damage to coral reefs or beaches
Name one environmental concern related to fracking.
Groundwater contamination or increased seismic activity (earthquakes)
How is oil and gas formed?
From the remains of marine organisms (like plankton) that sank to the sea floor millions of years ago, buried under layers of sediment and transformed by heat and pressure.
What is one limitation of hydroelectric power?
It can flood large areas, displace people, and disrupt ecosystems like rivers and fish habitats.
What is the name of the process where the nucleus of an atom splits to release energy used in nuclear power
Nuclear fission
WHAT IS MARPOL
MARPOL is the International Convention for the Prevention of Pollution from Ships. It's the main international treaty aimed at preventing pollution of the marine environment from ships, both from accidental incidents and routine operations.
Biogas, bioethanol, biomass and biodiesel
How is coal formed?
From the remains of ancient plants in swampy forests, buried and compressed over millions of years under heat and pressure.
What is one limitation of solar power?
It only works efficiently during sunny weather and cannot generate electricity at night without storage systems.
Name one major environmental or safety concern related to nuclear power plants.
Radioactive waste (or nuclear accidents like Chernobyl or Fukushima)
HOW TO PREVENT AN OIL SPILL FROM SHIPS
WITH A DOUBLE HULL
ELECTRICITY GENERATION PRODUCES A GREENHOUSE GAS:
The main greenhouse gas produced by electricity generation is carbon dioxide (CO2), which is released when fossil fuels are burned.
