Answer:
1.A fertile area in desert where water is found.
2.This circular geologic feature is thought to be caused by an uplifted dome-geologist would classify it as a domed anticline-that has been eroded to expose the originally flat rock layers.
Answer: Its presence is a good determinant of past hot climates. Its absence can also indicate cold climates.
Explanation:
18O and 16O are oxygen Isotopes, and are used in determining past climates. Heavier than the 16O with 10 neutrons and 8 protons, the 18O does not evaporate as easily and because of this, higher amounts are found in the tropics.
Together, they serve as good determinants of past climate by checking for their ratio in fossils.
Also the 18O isotopes are not present in polar regions as they precipitate before getting to higher altitudes. Cold areas, on the other hand, are high in 16O as they get trapped in glaciers. When climate changes in a location, the quantity of both of these oxygen isotopes also changes.
1.51 is the partial pressure of gas Y. as At 300 K, the volume of the flask that contains a gaseous mixture of two gases, X and Y, is 20 L. If the total pressure of the container is 2 atm and 0.1.
<h3>What is
gaseous mixture?</h3>
The gaseous combinations that are properly considered in this book are blends of different ingredients that may or may not vary outside of certain bounds.
These gases often belong to the category of "fuel gases," and each gas is any of a number of fuels that are gaseous at normal temperatures and pressure.
Thus, 1.51 is the correct answer.
