Inventions: Spinning and weaving, The steam engine, and The internal-combustion engine and the automobile
Explanation: The defining invention of the Industrial Revolution was most definitely the steam engine. The steam engine was the energy behind the most advanced textile inventions, such as the spinning mule and the power loom. It symbolized the transition from human power in homes to machine power in factories.
I can't answer your question until you give me the answer choices.
The atmospheric concentrations of CO2 during Earth's past have always been changing, sometimes slowly, sometimes abruptly. The changes continue to the present day, and will continue in the future. The reasons for the oscillations in the CO2 levels are numerous, but while in the past they have been exclusively from natural causes, in modern times it is also the humans that got involved in it. The Cretaceous period had 1000 ppm of CO2, while the Eocene had 560 ppm of CO2. In the present, the CO2 concentrations are 405 ppm, thus significantly lower than the Cretaceous and Eocene. What can be learned from these two periods though is that such high concentrations of CO2 result in much warmer global climates, with ice sheets lacking, and the temperatures being much more equalized across the latitudes. If the current trend continues, there is every chance that our planet will experience such changes in the near future.
Answer:
B
Explanation:
While there are indeed many natural resources, the use and extraction of these resources has not always been done in an environmentally friendly way.
Potable water is still a scarce commodity and is slowly being supplied to the population. Despite the efforts, a combination of salt water infiltration into the water table and chemical spills from refineries and other industrial sites make water pollution a serious issue.
