You can see more details depending on how "zoomed in" it is or how small the portion is. For example if you look on a map of the world you can see the landforms and bodies of water, but if you look at one of just the US you can see the different state borders as the state capitals, lastly if you look at one of just a single state you can see all the different streets and all the city's located in that state.
Answer:
As rocks on the earth go through various cycles, similarly the variation in chemical take place.
Explanation:
- As there exists a difference in the composition of minerals chemical composition from there pure forms, some variation exists in the chemical composition of elements like the size of irons, ad the temperatures at which the crystal grows.
- As rocks are an aggregate of more than one mineral they have distinct qualities like the granite is defined by the by proportions of quartz, and feldspar. Like the coal is a sedimentary rock being composed of carbon.
- The presence of oxygen, silicon, magnesium, calcium, and sodium in rocks defines their constituents, as by far Oxygen and Silicon is two of the most dominant 47% and 28%.
- An example of chemical alteration on earth is the volcanic rocks that are both igneous and metamorphic Depending on the chemical properties of these rocks the various metallic nature of elements the rocks have different temperatures and magnitudes.
Answer:
a. the mekong river is the longest
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.
