8. Name and describe the three main parts of the Understanding Global Change model. Select three
processes or phenomena explored in this chapter
and describe how they are related to each other.

Hey Buddy,Answer :-

The main causes of climate change are: Humanity's increased use of fossil fuels ...

such as coal, oil and gas to generate electricity , Run cars and other forms of transport , And power manufacturing and industry.

Increasingly intensive agriculture – which emits greenhouse gases like methane and nitrous oxide.

• Human population growth :- Global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2020. • consumption :-globalization decreases the cost of manufacturing . This means that companies can offer goods at a lower price to consumers . The average cost of goods is a key aspect that contributes to increases in the standard of living. Consumers also have access to a wider variety of goods.•™Energy use , land use change :- Interestingly, the findings indicate that globalization is positively correlated with energy consumption in the long - term for the two countries . Furthermore , Globalization shares a robust long - term relationship with energy consumption . Energy consumption is strongly related to globalization in the long - term.Addressing global land availability is made more complex by the processes of economic globalization . In particular, cropland expansion and forest conversion are accelerated by global - scale spatial dynamics caused by the displacement, rebound , cascade , And remittances effects.• pollution are driving forces of global change :- Some air pollutants cause the climate to warm. The recent increase in greenhouse gas pollution is trapping excess heat and causing the climate to warm. Air pollution includes greenhouse gases such as carbon dioxide. Greenhouse gases cause the climate to warm by trapping heat from the Sun in the Earth's atmosphere.Hope this helps you...#Carry on learning#Have a nice day ahead...!

Cells duplicate their DNA when they decide they need to divide. Cells divide for three main reasons: growth, repair, and reproduction. This could be during mitosis or meiosis.
