c
Explanation:
which is blue light. It has the shortest wavelength in the rainbow
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.

Siberia is a vast region, mostly in the territory of Russia, and it is divided into three large regions.
<em>Western Siberian Plain/Lowland
</em>
Located between the Ural Mountains and the Yenisei River. Occupies the western part of Siberia, and it is mostly composed of lowlands covered with dense forest, the taiga. The northern part is dominated by the tundra.
<em>Central Siberian Plateau
</em>
Located between the Yenisei River and the Lena River. Occupies the central part of Siberia, and it is mostly dominated by a plateau which gains in height on the southern part and is lowering on the northern part. The lower parts are covered with the taiga, while the higher are barren. The northern part is dominated by the tundra.
<em>East Siberian Highlands </em>
Located between the Lena River and the Pacific Ocean. Occupies the eastern part of Siberia, and the dominated land forms are the mountains, mostly the Kolyma Mountains. Depending on the elevation, the lower parts are covered with the taiga, while the higher are barren. The northern part is dominated by the tundra.
<u>Answer:</u>
D. Preventing people from visiting wildfire-prone areas
This would cause the greatest reduction of wildfires
<u>Explanation:</u>
Anthropogenic activities are the main source for forest fires. Humans intentionally or unintentionally became the reason for forest fires than lightning, rainfall deficit, and wind speed. Forest people responsible for causing fires because of shifting cultivation and livelihoods. Sub tropical forest were fired for cattle rearing becuase dense forests are not fit for cattle rearing. Increase in lightning storm also causes the forest fire. Decrease in rainfall leads to forest fire in Equator and tropical regions because of high temperature and high wind speed.
