Many kinds of data can be gathered in the study of ocean water. predictions are based on accurate and precise scientific data. which of these sets of data will yield the most precise data? a. temperature readings that have a range of 2°c depth b. readings that have a range of 4 km salinity c. readings that have a range of 20% density d. readings that have a range of 40 kg/l

I believe the correct answer is A. temperature readings that have a range of 2°C depth. This should be correct because 2 degrees is a small number, meaning that there isn't much space for mistakes here. However, the other options provide larger numbers, such as 4 km, 20%, and 40 kg/L, which is obviously much larger than 2 degrees, which means the results won't be as precise and accurate.

The answer is magnitude measures the effects of an earthquake on the area , while the intensity measures the strength of an earthquake.
