The image manipulation used in the given picture is cropping. The tool is helping to bring foucs on a man rowing a raft.
So, correct answer is cropping or crop tool.
NOTES: Global mean surface temperature from 1880 to 2018, relative to the 1951–1980 mean. The black line is the global annual mean, and the red line is the five-year local regression line.
The report of the Intergovernmental Panel on Climate Change of October 2018 showed that the difference in impact between 1.5°C and 2°C was very large. That 0.5°C increase would imply that, for example, the length of droughts would double, the occurrence of extreme weather events would more than double, and all the coral would be gone. That is why the UNFCCC Paris Agreement (COP21) of December 2015 – to which more than 190 countries have subscribed – wisely set the target of holding temperature increases to “well below 2°C” with efforts to hold to 1.5°C.
To have a reasonable chance of holding below 2°C, we have to cut emissions by around 40% absolutely in the next two decades. Much bigger cuts are necessary for 1.5°C.
<em>BONUS: </em><em>Global warming is the process of raising the average temperature of the earth's atmosphere, oceans, and land. The global average temperature on the earth’s surface has risen 0.74 ± 0.18 ° C over the last hundred years. The Intergovernmental Panel on Climate Change (IPCC) concluded that "much of the increase in global average temperature since the mid-20th century is most likely caused by increasing concentrations of greenhouse gases due to human activity" [1] through the greenhouse effect. These basic conclusions have been expressed by at least 30 scientific and academic bodies, including all national academies of science from the G8 countries.. The climate model used as a reference by the IPCC project shows that global surface temperatures will rise by 1.1 to 6.4 ° C between 1990 and 2100. </em>

The experiment fit into the "big picture" purpose of the scientist's research because C The scientist could repeat the experiment with blocks of limestone of different sizes in each beaker in order to compare the effects of the two different acid concentrations. The scientist could then make a conclusion about which concentration of acid has a stronger effect on the limestone.
<h3>What is
experiment?</h3>
An experiment can be regarded as a procedure that is a been carried out in order to support or refute a hypothesis.
It is been carried out in order to determine the efficacy or likelihood of something that has not been tried.
It should be noted that Experiments provide insight so as to know the outcome using some factors.
