Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.
Identify the part of the slow carbon cycle in which the total amounts of carbon is most likely decreasing the most and explain why this decrease occurs.
Answers
Answer:
Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. as u know decreasing means going down and increasing means going up. the reason why things decrease means something went wrong or something to happen to make it go down we all try to make things increase which means we try to make things go up instead of down. a lot of reasons is y things decrease is bc during the period of time something might go wrong or happen in a bad way that makes a lot of things decrease. for example like temperature when the temperature decreases it means it goes down and it might get cold but if the temperature increases it goes up so it might be ht or warm or maybe even cool. if something ever decreases it means during the period of time something bad happened and made it go down instead of up if something ever goes wrong that means something decreased. sometimes decreasing could be a good thing but most of the time it it bad but there are sometimes when decreasing is good but not all the time.
The part of the slow carbon cycle in which the total amounts of carbon is most likely decreasing the most is from 1960 to 1970.

Answer: D : moderate amounts of precipitation
Explanation:
The one characteristic that temperate marine and temperate continental climates have in common is moderate amounts of precipitation. Thus, the correct option for this question is D.
What is Climate?Climate may be characterized as the long-term pattern of weather in a particular area. It is different from the weather in a way that can change from hour to hour, day-to-day, month-to-month, or even year-to-year.
According to the context of this question, A maritime climate is influenced by a nearby ocean. A continental climate is influenced by nearby land. The temperature of offshore currents affects nearby land areas.
A maritime climate is less extreme than a continental climate because the ocean moderates temperatures. Due to this, both temperate marine and temperate continental climates have moderate amounts of precipitation.

Answer:
There is solid proof that global warming is increasing and getting worse by t he day. The ice caps slowly melt more and more each year due to this which is a proven fact. On top of that, it has been proven that carbon emission by humans is bad for the environment and it helps increase the problem of global warming by weakening our atmosphere. As for the cold days, just because we have global warming doesn't mean the earth weather wont be cold. global warming is something that slowly happens and over time the temperature global has actually been increasing at a not very notice able pace.
Explanation:
Yes, climate is changing because of the human activities which are causing harm to the environment causing global warming.
What is global warming?Global warming is the long-term warming of Earth's climate system that has been seen from the pre-industrial period (between 1850 and 1900) as a result of human activity, principally fossil fuel combustion, which raises heat-trapping greenhouse gas levels in the atmosphere.
