The unsaturated zone is the area of the subsurface that is above the groundwater table. The pores of the soil and rock in this zone contain both air and water.
<h3>What is the water table?</h3>
The water table is the subsurface border between the unsaturated and saturated zones.
The water table is an underground border that separates the soil surface from the area where groundwater saturates crevices between sediments and rock fissures.
At this point, the pressures of water and air are equal.
The unsaturated zone is the soil surface above the water table, where both oxygen and water fill the crevices between particles.
Therefore Option C is correct as it is where a person will immediately reach after drilling a well through an unsaturated zone.

Answer:
Parallax would be most effective in measuring distances to stars which are close to the Earth.
Explanation:
In the experiment,
- The parallax shift would decrease as the pencil would move further away from the scientist's eye, so option 1 would be invalid.
- the size of the pencil remains constant, so option 2 would be invalid.
- the parallax shift can be observed when the pencil has objects in the background to provide relation, that is to say, the shift of the pencil when seen relative to background objects; therefore, if we assume that the pencil is a star nearby to the Earth, and the background objects are stars that are further away, then the shift of, and thus, distance to the nearby star can be easily observed.
These were the Muslim minorities from the Balkans. This happened in the southeast of Europe during the 19th century. Due to discrimination and persecution, they were forced by the majority to flee their homelands. Specifically, this happened in 1912 during the Balkan Wars. They were shunned because of being part of the ethnic minorities.

Answer:
Coastal dunes are a ridge, or a series of ridges, that form at the rear of a beach and differ from most other constructional coastal landforms in that they are formed by the movement of air (aeolian transport) rather than by tidal, wave, or current action.A coastal plain is a flat, low-lying piece of land next to the ocean. Coastal plains are separated from the rest of the interior by nearby landforms, such as mountains. In western South America, a large coastal plain lies between the Andes Mountains and the Pacific Ocean.
