reason for climate change and global warming
Global warming is an aspect of climate change, referring to the long-term rise of the planet's temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, and farming.
Climate change is the result of global warming.
The root cause of global warming is the increase of heat-trapping greenhouse gases. These gases help regulate the Earth's heat balance but when in more quantities, it disrupts this balance by retaining more and more heat; thereby gradually increasing the global temperatures. This process is called global warming.
Now the ultimate cause of global warming is anthropogenic activities. There are also natural causes that supplement greenhouse gases in the atmosphere like volcanic eruption. Some reasons are:
Industrialization - More development means more industrialization. More industries mean more greenhouse-gas emissions.Mining and other exploration activities - Large-scale mining and oil explorations require the use of fossil fuels to power them and land degradation and more carbon dioxide in the atmosphere. Open fields of methane gas are also a threat because it a greenhouse gas. The melting of glaciers due to climate change and global warming releases more methane gas as the melting snow uncovers dead frozen organic matter to the surface.Deforestation - Forests are carbon sinks, in the sense that the trees absorb atmospheric carbon and purify the air. Reducing forest cover means more amount of free carbon dioxide in the atmosphere.Urbanization - Countrysides and natural wetlands which are areas of carbon sequestration get turned into urban areas. Urban areas are industrialized as more factories come in and get turned into areas expelling carbon dioxide, unlike natural areas which absorb carbon dioxide.Commercial farming and poultry - Large-scale commercial farming depends on fossil fuels, pesticides, antibiotics, and synthetic fertilizers. Extensive areas of natural area are converted into poultry farms which multiply animals per unit area and release CO2.Overuse of resources and consumerism - This is due to the fact that the manufacture of the items we use and purchase on a daily basis accounts for 45% of all global greenhouse gas emissions.To learn more about the effects of global warming:

MOVEMENT How would you describe the difference between changes in the geographic center and changes in the population center?
Answer:
The mean center of population is the place where an imaginary, flat, weightless, and rigid map of the United States would balance perfectly if all residents were of equal weight. Historically, the movement of the center of population has reflected the expansion of the country, the settling of the frontier, waves of immigration and migration west and south. Since 1790, the center of population has moved steadily westward, angling to the southwest in recent decades.

Consulted for historical reference: Historical Atlas of the United States, National Geographic Society, 1988.
NOTE: The Proclamation Line of 1763 limited British settlement to areas east of the Appalachian Mountains. Alaska and Hawaii were not included in the calculation of the mean center of population until 1950. Puerto Rico was not included in any decade.

Some geologists are finding evidence that suggests that this one-mile deep canyon may have been cut within the last 4 million years. Assuming a uniform rate of erosion and without considering canyon widening due to slope retreat, calculate how much (in millimeters per year) the Colorado River would have to downcut per year to form this mile-deep canyon in 4 million years. Show your work and clearly indicate what each quantity represents.
The number that Colorado River would have to downcut per year to form the mile-deep canyon in 4 million years is 0.40 millimeter per year.
Depth of canyon = 1 mile
Time taken = 4 million years
Based on the above information, the rate will be:
= Depth / Time taken
= 1 mile / 4 million years
= 0.25 mile / million year
Note that 1 mile = 1609344 millimeter
Therefore, the rate will be:
= (0.25 × 1609344) / 1000000 years
= 0.40 millimeter / years
In conclusion, the rate is 0.40 millimeter per year.
