Greenhouse gases
Which gas is the most abundant greenhouse gas produced by human activity through burning fossil fuels.
carbon dioxide (CO₂)
Clearing forests for farming is an example of this human activity.
deforestation
Energy is a measure of the amount of movement experienced by these.
particles
Waves that need a medium (particles) to travel are called this.
mechanical waves
Plants remove this gas from the atmosphere during photosynthesis.
carbon dioxide (CO₂)
Which greenhouse gas is released by livestock and contributes to global warming.
methane (CH₄)
Burning coal, oil, and gas releases this into the atmosphere.
carbon dioxide (CO₂)
Heat transfer through direct contact between particles is called this.
conduction
Waves that do not require a medium and can travel through space.
electromagnetic waves
The process where living things release CO₂ back into the atmosphere.
respiration
Which gases trap heat in the atmosphere, keeping Earth warm enough for life.
greenhouse gases
The rise in Earth's average temperature due to greenhouse gases is called this.
global warming
Heat transfer in fluids, caused by warmer, less dense parts rising and cooler, denser parts sinking.
convection
The distance between two wave peaks is called this.
wavelength
The breakdown of dead plants and animals returns carbon to the soil or atmosphere through this process
decomposition
Which long-lived greenhouse gas is mainly released by industrial processes and contributes to ozone depletion.
nitrous oxide (N₂O)
The result of global warming that can affect sea levels and weather patterns.
climate change
Energy transfer via electromagnetic waves, not requiring particles, is called this.
radiation
The number of wave cycles that pass a point per second is called this.
frequency
This process releases carbon dioxide when humans burn wood, coal, or oil.
combustion
This human activity increases greenhouse gas levels in the atmosphere and accelerates global warming.
burning fossil fuels / deforestation / industrial activity
Human activities that increase greenhouse gases are said to have this type of effect on the planet.
anthropogenic (human-caused)
The faster the particles move in an object, the higher its _____.
temperature
The maximum height of a wave from its rest position is called this.
amplitude
The movement of carbon between living things, the atmosphere, oceans, and Earth is called this.
