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
The answer would be C) Intensity. This is because intensity is the measure of the strength and amount of shaking produced by an earthquake. This can be mistaken for magnitude, but magnitude measures the amount of energy released at the source of the earthquake. Hope this helps and have a great day!
Answer:
The presence of mustones by curiosity rover indicates chances of ancient life.
Explanation:
- The Yellowknife bay is a geologic formation of the Gale crater on the planet Mars and NASA named the rover as a curiosity. Its primary goal was to assess the potential habitability and whether the mars are capable to support life.
- The presence of the mudstones in the geologic depression area on mars leads to its name as Yellowknife i.e the capital of the northwest territory of Canada.
- The findings of the mudstone from the stepped bedded stata indicate the clay minerals that show the presence of water and claims that an ancient creator was found on in this region and these indicators of a potential mafic source of origin of deposition.
Answer:
The process of desertification presents a serious impact on the well-being and health of the people living
in the areas affected by droughts and land degradation
on an unprecedented global scale. The worst situations
can be found in Africa, which is threatened because the
land degradation processes affect about 46 percent of
the whole continent and create a health risk to people
living in the regions far beyond the affected areas.
