Green house effect
Define the greenhouse effect.
A natural phenomenon which is responsible for trapping heat in the Earth's atmosphere, making it suitable for supporting life.
This human-driven land-use change involves clearing large areas of forests, reducing the number of carbon sinks, and increasing carbon dioxide levels in the atmosphere.
Deforestation.
Name 2 natural carbon sinks
Forests and oceans
The term for the gradual increase in Earth's average temperature, enhanced by human activities.
Global warming
What is a sign of Global warming?
Extreme weather, ice caps melting, ocean acidification
3 main greenhouse gases responsible for trapping heat in the Earth's atmosphere.
carbon dioxide (CO2), methane (CH4), and water vapor (H2O)
Main cause for increase in deforestation and farming?
Increase in population
Worded equation for photosynthesis.
Carbon Dioxide + Water = Glucose + Oxygen
Climate Change is a naturally occurring phenomenon and doesn't need to be altered. True or False
False
What is the term for the total amount of greenhouse gases, primarily carbon dioxide, emitted by human activities such as burning fossil fuels and deforestation?
Carbon Footprint
What is global warming?
The enhanced greenhouse effect, driven by human activities.
In the hydrosphere, glaciers play a vital role. How do glaciers respond to climate change, and what do they impact?
Glaciers recede and shrink, contributing to sea level rise and can affect freshwater resources.
2 major natural processes that produce carbon dioxide
Respiration and Decomposition
Sun emits short wave radiation, and the earth emits what kind of radiation?
Long wave infrared radiation
3 Human activities that release large amounts of CO2.
Farming - particularly cows, deforestation and burning of fossil fuels
Largest contributor to the increase in atmospheric carbon dioxide levels.
Burning of fossil fuels (e.g., coal, oil, and natural gas) for energy and transportation
Common misconception about the increase of carbon dioxide on the atmosphere.
That the ozone layer becomes ticker - not true.
Valcones are a natural example of what part of the carbon cycle?
Release CO2 into atmosphere from lithosphere
Increased carbon dioxide levels in the atmosphere are leading to this phenomenon, which affects the chemistry of the oceans and marine life.
Ocean Acidification.
Which greenhouse gas, released through activities like livestock farming and rice cultivation, is over 20 times more effective at trapping heat in the atmosphere than carbon dioxide?
Methane (CH4)?
