Answer:
Beyond the <u>Atmospheres</u> that surrounds Earth, there are seven other planets. All planets in our <u>Solar system</u> revolve, or make <u>rotation </u>around the sun. All the planets get <u>energy </u>from the sun. The <u>features </u>of planets differ in some ways. For example, the <u>surface </u>of Mars is <u>solid </u>and rocky, but Saturn is gaseous. There are also differences in size, or <u>measurement </u>.

Streams erode sediment from their banks. They pick up and transport sediments. As a stream erodes its banks, it creates a V-shaped valley (Figure above). This contrasts with the U-shaped valleys created by glaciers.
It is true that the rainfall that happens in savannas especially in summer time reaches to only half of the annual rainfall. Isolated trees and some types of shrubs are found in savanna. The precipitation rate received by savannas per year is about 30 to 50 inches.
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.
