What are greenhouse gases and how do they impact climate change?
Greenhouse gases are gases that trap heat in the Earth's atmosphere, leading to the greenhouse effect. They include carbon dioxide, methane, nitrous oxide, and fluorinated gases. These gases absorb and emit radiation within the thermal infrared range, causing the Earth's surface temperature to rise. This increase in temperature contributes to climate change by altering weather patterns, sea levels, and ecosystems.
Greenhouse gases are primarily composed of oxygen and nitrogen, which do not affect the Earth's temperature.
Greenhouse gases are only emitted by natural sources and do not impact climate change.
Greenhouse gases are gases that cool the Earth's atmosphere, leading to a decrease in temperature.
List three human activities that contribute to climate change and explain their effects.

Using renewable energy sources
Planting trees

Explain the concept of climate feedback loops and provide an example.
Climate feedback loops are static processes that do not impact the environment
An example of climate feedback loops is the direct relationship between CO2 emissions and temperature rise
Climate feedback loops only occur in isolated ecosystems and not on a global scale
Climate feedback loops are processes in which the result of an initial change leads to further changes that amplify or dampen the original change. An example is the ice-albedo feedback loop, where melting ice reduces the Earth's albedo, leading to more absorption of heat and further ice melting.
What are greenhouse gases and how do they impact the Earth's climate?
Greenhouse gases are gases that trap heat in the Earth's atmosphere, leading to the greenhouse effect and impacting the Earth's climate by causing global warming and climate change.
Greenhouse gases are gases that cool the Earth's atmosphere, leading to lower temperatures.

Describe the phenomenon of global warming and its implications on the planet.
Global warming is the long-term increase in Earth's average surface temperature due to human activities, primarily the burning of fossil fuels and deforestation.
