The statement that shifts in the rock layer locations cannot account for gaps in the rock record is false. In contrast, shifts in the rock layer locations should account for gaps in the rock record.
Any gap in age of rock between rock layers is called an uncomformity. It is the contact between two layers representing a gap in the geologic record, usually from the erosion of the layers which would normally be expected to appear.
-condensation
-triangulation
-intersection
The correct answer is - triangulation.
Triangulation is the technique used for getting the most accurate information about the epicenter of an earthquake. This technique is very simple. Three seismograph stations, on different locations, that are able to record the earthquake, are working together and comparing the results they got from where their respective stations showed the earthquake's epicenter is. The circles that represent the area affected by the earthquake, are than compared and the point of their intersection is considered to be where the epicenter is.
B) desalinization of salt water from the Persian Gulf.
C) importing water using the same ships that transport oil.
D) pumping water from the Black Sea through an overland pipeline.
Countries which border the Persian Gulf such as Kuwait have very limited fresh water supplies, and many are forced to search for water from other sources such as desalinization of salt water from the Persian Gulf. Therefore, the option B holds true.
Desalinization can be referred to or considered as the process of treatment of water such that the salt contents present in the salty water are eliminated.
By the way of this process, water becomes safe for consumption and usage. It is an alternative for countries that have limited supplies of fresh water. This process is used extensively in the countries surrounded by the Persian Gulf.
Therefore, the option B holds true and states regarding the significance of the desalinization.

Answer:
After its main Sequence existence a medium sized star like our sun becomes a red giant.
Explanation:
A red giant star is a large reddish star whose mass ranges from about 0.3 to 8 times the mass of our sun. Red giants are stars that are already at an advanced stage of their “life”. .
At this stage, due to the fusion of hydrogen into helium in the outer layers, these same layers eventually expand into a red giant. At this stage the star has already left the so-called main sequence.
A red giant star has a diameter of a few dozen, or even hundreds of times the diameter of our sun. However, the limits of this star are not well defined due to the low density of the outer layers.
The surface temperature of a red giant is relatively low, usually no more than 5,000 K.
Later, the red giant star eventually expels its outer layers, forming what we call the planetary nebula. Meanwhile the red giant's core remains cohesive by its own force of gravity. This nucleus that remains of the red giant becomes a white dwarf, a small but very dense star.
Examples of red giant stars: Aldebaran and Arcturus.
