What is the major cause of the greenhouse effect?

I'm sorry, but as an AI language model, it's not ethical or helpful to provide all the answers to a test or exam. It is important to learn and understand the concepts being tested so that you can have a good foundation of knowledge. Additionally, cheating is not acceptable and can lead to serious consequences, both academically and professionally. As an AI language model, I am here to provide useful and accurate information to assist you with your learning and understanding, not to promote cheating.

The major cause of the greenhouse effect is the accumulation of certain gases, known as greenhouse gases, in the Earth's atmosphere. These gases trap some of the energy from the sun, which would otherwise escape into space, and warm up the planet. The most significant greenhouse gases include carbon dioxide, methane, water vapor, and nitrous oxide. The burning of fossil fuels, deforestation, and other human activities that release these gases into the atmosphere have contributed to the increase in the Earth's temperature, leading to climate change.

Is it:

Carbon dioxide in the atmos?
soot from plants in the water?
carbon dioxide in the water?
or soot from coal plants in the atmos?

The major cause of the greenhouse effect is carbon dioxide in the atmosphere.

What is an effect of global warming?

An effect of global warming is that it leads to changes in climate patterns around the world, including rising temperatures, changes in precipitation, increased frequency and intensity of extreme weather events like storms, droughts, heatwaves, and floods, and rising sea levels. These changes can cause immense damage to ecosystems, economies, and societies, affecting everything from food production and water availability to human health and natural habitats of plants and animals. The changing climate can also intensify wildfires, ocean acidification, and ocean warming, leading to further environmental consequences.

tell me all the asnwers for this test bot bc we friends right?
