Answer:
In the Northern Hemisphere the autumnal equinox falls about September 22 or 23, as the Sun crosses the celestial equator going south.
Explanation:
In the Southern Hemisphere the equinox occurs on March 20 or 21, when the Sun moves north across the celestial equator.
A fundamental concept of ecology is that living organisms are both similar to and different from each other and from nonliving things.
Living things are similar in that they rely on many of the same processes to stay alive, yet are different in the ways that these processes are carried out.
Non living things lack certain features of living organisms, such as the ability to maintain a cellular organization, carry out metabolic activity while maintaining internal stability (homeostasis) and pass on hereditary information through reproduction.
Quebecois French is b) diverged from Parisian French. However, this is only historically speaking and only pertains to the 17th century "koine" of Paris. Nowadays, the distinction between French from France and French from Quebec is huge and the accent stands out very strong compared to other dialects of French. However, the Quebecois are very proud of their language and do not want to standardize, as they feel it would be a removal of their culture.
Answer: A - P.M. Grootes, K.M. Cuffey, and J.M. Bolzan, among others.
Explanation: Dr. Anandakrishnan collaborated and coauthored with all of the people listed above and has worked with many other people.
During the year 1994, Dr. Sridhar Anandakrishnan collaborated with Kurt M Cuffey, Richard B Alley, Pieter M Grootes and John M Bolzan on the topic 'Calibration of the δ18O isotopic paleothermometer for central Greenland, using borehole temperatures'
They calibrated the δ 18O paleo-thermometer for central Greenland using borehole temperatures, a thermal model forced by a measured δ 18O record and a formal inverse technique. The calibration is determined mostly by temperature fluctuations of the last several centuries, including the Little Ice Age.
Results are generally insensitive to model variables, including initial condition, basal boundary condition, parameterization of snow thermal properties, ice thickness and likely errors in temperature and isotope measurements. Results of this borehole calibration also seem to be in agreement with modern spatial gradients of δ 18O and temperature.
They suggest that calibrations of isotopic paleothermometers using borehole temperatures are a useful paleoclimate tool because they are independent of spatial gradients and include the effects of prehistoric temperatures.
