The answer is A.
Ice Age or glacial period refers to the extended period of well-below-average temperatures. It is a prolonged period where reduction in the temperature of the Earth’s surface and atmosphere are caused by the expansion of continental and polar ice sheets and alpine glaciers. Usually this phenomenon occurs in the northern and southern hemispheres where extensive ice sheets are seen most.

Answer: A is the correct answer
Explanation: a pull factor is something that attracts people, so moving somewhere because you found a great new school is a pull factor. The other answers are push factors
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.
Answer:
I think the answer is Imagery
The answer is 3%
Explanation:
3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.
