Answer:
B. both water and calcite contain oxygen.
Explanation:
water molecules are not equal some are substituted with a heavier counterpart,the standard Oxygen molecule can be substituted by the 18O and hydrogen by H2 given rise to H216O,HD16O and H118O they are termed isotopologues and gave different physical properties.First, over the ocean, the heavier isotopes are less likely to take part in the formation of moisture, leading to lower concentrations of the heavy isotopes in the clouds compared to the mean oceanic water isotopic composition (lower concentration means that the δ18O is more negative). Then, as the air masses move toward the poles, temperature decreases leading to precipitation (either liquid or solid). The heavier isotopes will be preferentially found in the condensed phase than the light ones, which depletes even more the cloud from its heavy isotopes. Finally, in remote areas of the Polar Regions, the isotopic content of the final precipitation results from successive precipitation events. Since, as we saw, the precipitation contents in each isotope are different, each successive precipitation event will have a different isotopic composition, with the final one having the least heavy isotopes – a process called distillation. At each step of the moisture’s path from ocean to cloud to precipitation, the isotopic fractionation is strongly influenced by temperature. This leads to a temperature signal in the isotopic composition of both vapour and precipitation
Answer:
Some geologic processes happen quickly, while others happen over millions of years.
Explanation:
uniformitarianism and catastrophism are geological terminologies which are used to describe events.
Catastrophism is a term used in geology to explain the theory that the Earth is shaped by sudden occurrences which takes place from time to time,these events don't last long.
Uniformitarianism is a terminology used in geology to explain that the Earth is shaped by gradually occuring events or activities which takes place over time, Uniformitarianism can also be described as GRADUALISM.
The answer is no. The Caucasus Mountain does not separate European Russia from Asian Russia. It was the Ural Mountains that separates the European Russia from Asian Russia. Ural Mountains is a mountain range that stretches approximately from northwestern Kazakhstan through the western part of Russia.
Answer:
Arabian peninsula lives in farming villages
Answer:
Oceans heat up and cool down much more slowly than land. This means that coastal locations tend to be cooler in summer and warmer in winter than places inland at the same latitude and altitude.
Explanation:
Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.
