Explanations provided below

Explanation:

1. The first graph shows us that between 800,000 BCE and 2015 CE, the atmospheric concentration of carbon dioxide was fluctuating between 170 ppm and 300 ppm periodically, meaning it would achieve a maximum value, then drop down to a minimum value and the process would repeat over years by negligible changes in the maximum and the minimum values.

However, of 1950 to 2015 CE, we see a steady exponential growth of the atmospheric concentration of carbon dioxide strongly exceeding any other peak values seen in the trends before.

2. Similar patterns are seen in evolution of sulfur dioxide gases as well, as sulfur dioxide is another gas causing environmental problems (acid rains) which increased in concentration significantly after industrial revolution.

3. We may conclude that in the following years, the levels of carbon dioxide will remain to rise, as it reached its greatest value throughout the ages and is still rising exponentially.

4. Notice that we see the rise from around 1850. This was caused by the industrial revolution and an excessive usage of machines and power plants, as well as production of the first cars, which all contributed significantly to the amount of carbon dioxide released into the surroundings.

Answer from: Quest

Mass is the amount of matter in an object. weight is the measurement of the pull of gravity on an object. say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165) now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon. however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant. in conclusion it is possible for your weight to change as your mass remains constant.
