Answer:
They are 4, Argentina, Brazil, Chile and Paraguay.
Explanation:
The tropic of Capricorn is an imaginary line is placed 23.5 degrees south of the Equator.
This is the zone where the sun is highest during the winter solstice, it was named around 2000 years ago by the Greeks. The word "troops", which means <em>turn</em>, because the sun seems to turn around in the opposite direction after every solstice.
The Andes are labeled with number 4.
The region labeled with number 3 is Patagonia.
Answer:
Coal is made by heating of woody plant material, and oil is made by heating of algae.
Explanation:
The coal and the oil are both fossil fuels. They have both been very important for the development that the humans have experienced since the Industrial Revolution as they were what provided the energy needed for this process, and they still do.
The coal is a fossil fuel that has formed from woody material, mostly from the Carboniferous forests. Once these forests collapsed, they were quickly covered with water, mud, and sediments. Over time they were covered with even more sediments, so they were getting deeper into the crust. As they were getting deeper into the crust this material was exposed to higher temperatures and pressures, leading to the formation of the coal over the course of millions of years.
The oil is a fossil fuel that has formed from the remains of the marine life, mostly algae. As the algae and the other marine organisms have been dying out, they have fallen on the bottom of the oceans, quickly being covered with the soft sediments. As more and more sediments have been placed on top of them, they too were getting deeper into the crust, so they were also exposed to higher temperatures and pressures, eventually leading to the formation of the oil over the course of millions of years.
In order to investigate past, present, and future social and environmental change in various parts of the world, human-environment interaction (HEI) provides a framework that brings together knowledge sharing both disciplinary depth and interdisciplinary scope.
All of these strategies must be interdisciplinary and integrate the social and natural sciences, and this is important.
<h3>How do social factors influence human interactions?</h3>
Numerous human activities such as overpopulation, pollution, the burning of fossil fuels, and deforestation have an adverse effect on the physical environment.
Climate change, soil erosion, poor air quality, and undrinkable water have all been brought on by changes like these.
