The groundwater and the aquifers essentially fall into the same category, as both of them are part of the underground freshwater reserves (though in some cases they can be saline as well). The groundwater tends to be mixed with ground very often. It also has the tendency to move inside the ground, making holes into the rocks or the ground and trying to find its way out on the surface. The aquifers, on the other hand, are much more static. They are larger bodies of water that are located inside the ground. In a way, they are like underground lakes, or rather reservoirs of water. The connection between these two, apart from being underground water bodies, is that the groundwater is often supplying the aquifers with water, thus recharging the water that they have lost though human usage or evaporation.
Considering the available options, the term that describes airflow from west to east is known as <u>Zonal Flow.</u>
<h3>What is Zonal Flow?</h3>
Zonal Flow is a term used to describe wind or airflow from the west-east direction.
The Zonal Flow can also flow along the Latitudinal lines or latitudinal circles.
Zonal flow is a term commonly used in atmospheric and geographical sciences, and it brings a temperature contrast along the Earth's longitude.
Hence, in this case, it is concluded that the correct answer is option A. "<u>Zonal Flow."</u>

Scientists in Japan have begun setting off explosives along a geological fault line analyzing the Earth's structure and trying to map the danger spots.
Explanation:
Japan lies in the world’s highest active earthquake belt along the Pacific Ring of Fire and is highly prone to earthquakes. Understanding and analyzing the activities of the geological fault lines helps to identify the danger spots of earthquakes and mark the hazard zones. This helps to prevent the damage of earthquakes by providing pre-warnings and precautions.
There are numerous fault lines across Japan and scientists are trying to identify the danger spots by triggering explosions along the fault line in the south-west of Tokyo. This fault line separates Japan mainland from the Pacific Ocean and the Sea of Japan.
The explosions help to analyze the movement of the tectonic plates underneath the Pacific Ocean and the Sea of Japan. This helps to track tsunamis arising from oceans during high-intensity earthquakes.
