Which three gases contribute the most to the greenhouse effect?
Carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O)
200
What is the lowest layer of Earth's atmosphere called?
Troposhere
200
How do magnets interact with each other?
Like poles repel each other, opposite poles attract.
300
Which natural process releases carbon dioxide back into the atmosphere?
Respiration
300
What happens with an incomplete combustion and what does it produce?
Incomplete combustion happens with limited oxygen, resulting in carbon monoxide, soot, or other byproducts.
300
What human activities increase greenhouse gas emissions?
Burning fossil fuels, deforestation, and industrial processes.
300
What layer of the atmosphere contains the ozone layer?
Stratosphere
300
What is the unit of magnetic field strength?
The unit of magnetic field strength is the Tesla (T)
400
What is the main human activity that increases carbon dioxide levels?
Fossil fuel combustion.
400
Define what non-renewable fuel is and name 3 examples.
Coal, Crude Oil, Natural Gas, Fossil Fuels, Propane, Butane, Uranium, Peat, Keosense
These fuels are limited in supply and contribute to environmental concerns when burned, making the transition to renewable energy sources a key focus for sustainability efforts.
400
What role do plants play in the greenhouse effect?
(name the specific process and describe what it does)
Plants absorb CO2 during photosynthesis, helping to reduce greenhouse gas levels.
400
What is the main function of the atmosphere?
Protect life on Earth
400
What is the right-hand rule in magnetism?
The right-hand rule is a convention used to determine the direction of magnetic force, electric current, and magnetic field: point your thumb in the direction of the current and curl your fingers; they will point in the direction of the magnetic field.
500
What are the four major types that carbon can be categorized into?
carbohydrates, lipids, proteins, and nucleic acids.
500
Define what renewable fuels are and give 3 examples.
Renewable fuels are derived from resources that can be replenished naturally over time.
Biodiesel, Ethanol, Biogas, Biojet fuel, switchgrass, hydrogen, algae-based fuels
500
What are the consequences of a strengthened greenhouse effect?
Rising sea levels, extreme weather events, and disruptions to ecosystems.
500
What gas makes up about 21% of Earths atmosphere?
Oxygen.
