Answer:
a i just took the test. :)
The global meteoric water line (GMWL) is a linear relationship that describes the isotopic composition of precipitation (meteoric water) in various regions of the world. It is represented by the equation:
δD = 8 * δ18O + 10
In this equation, δD represents the deuterium excess, and δ18O represents the isotopic composition of oxygen-18 in meteoric water.
Warm and Moist Areas: In warm and moist regions, such as tropical rainforests, you typically find precipitation falling on the lower-left end of the GMWL because both δD and δ18O values are relatively high. The warm temperatures contribute to higher values.
Dry, Colder Areas: Dry and colder regions, like polar areas or high mountainous regions, tend to have precipitation falling on the upper-right end of the GMWL, as both δD and δ18O values are relatively low. The cold temperatures and lower humidity contribute to these lower values.
The GMWL helps scientists understand the sources and processes influencing the isotopic composition of meteoric water in different climatic regions.
