An increase in atmospheric greenhouse gases are likely to cause many different things. Here are a few examples:
- Greenhouse gases (such as carbon dioxide, methane..) will cause the earth to get hotter. A hotter earth basically means global warming.
- The increased temperature will cause the polar ice caps to melt, which in turn increases sea levels (making some low-lying areas prone to flooding) and destroys habitats for many species (polar bears, for example).
- Extreme weather will become more commonplace, droughts will occur more often.
There are many more things that I can include but if I were you I'd go check out BBC Bitesize, it's a website that includes lots of different subjects including Geography. I'm not sure if you're in the UK but even if you aren't it will be worth to give it a look. Hope this helps!
Your question is asking about
Human Impact
Introduction to Human Impact
Human impact on the environment carries many negative longterm consequences.
Consumption, altering habitats, and carbon emissions are all human activities destroying the natural world.
Habitat Alteration
Habitat alteration is changing earth's natural compositing by destroying habitats to build upon or fragmenting habitats for roads and access. This is the biggest threat to biodiversity.
Pollution
Pollution is the contamination of Earth's atmosphere and surface (land and bodies of water).
Disposal of human waste results in land pollution, while burning fossil fuels results in air pollution. Land and air pollution affect water contamination.
Deforestation
Deforestation is the removal and destruction of forests.
Clear cutting completely removes all trees in an area for human consumption, such as building materials, paper products, etc.
Human Population Growth
The human population has continued to increase, which means human impact on the environment will increase as well.
Concerns include lack of space, food, and other resources, as well as disease outbreaks.
Acid Rain
Acid rain is caused by burning fossil fuels, which releases acidic gases into the atmosphere. The gases latch on to water molecules and the result is acid (low pH) rain.
Acid rain results in organism death and destruction of infrastructure.
The answer would be, a plate slides beneath another plate due to convection currents and gravity.
Answer: China, India, Russia, and Indonesia are the continent’s most productive mining economies.
But the richest country is China. China is the world’s largest aluminum, gold, tin, and coal producer.
Explanation:
Answer: C. maintains human civilization at the expense of the environment.
Explanation:
Sustainable development is the principle for the fulfilling the needs of the present as well as the future generations of the human society without causing any harm to the natural environment.
It suggests that the natural resources should be used in a manner such that they remain available for present as well as for the future generations.
All the options are correct except C. This is because of the fact the sustainable development emphasis over the protection of environment while the creation of civilization of the human society remain continues.
