Answer:
The correct answer to the question: Which of the following is an example of chemical weathering, would be, C: Oxygen reacting with the minerals in rocks.
Explanation:
Chemical weathering, especially in rocks, is defined as the changes that rocks suffer as they come in contact with water and its chemical components, that through reactions, alter the formation of these rocks. There are several ways in which the contact between water and rocks causes this weathering, one of which is called hydrolysis, which is, the way in which the water and rock minerals combine together to change the structure of rocks, like is the case of feldspar. Another one is when oxygen combines with the minerals of the rocks, to cause oxidation, which leads to rocks accumulating rust, becoming weakened so they easily break, and acquiring a redish-brown color. This is why the answer is C.
There are a few characteristics that total institutions have in common with one another. For Goffman, the most significant characteristic of total institutions is that they all involve a kind of separation from the rest of society.
Systematic Observation is a method used to understand how a particular activity or task works. The researcher observes the stages of a process, the tools used, the difficulties that appear, the conversations and the results of the work.
From this method the conclusion is a consequence of the whole process so it is acquired, the whole process of analysis will lead to the conclusion.
Answer:
The Mekong River, a critical waterway for six countries in Southeast Asia, is registering critically low water levels this summer.
The Mekong River Commission (MRC), which monitors Southeast Asia's longest river, reported in mid-July that water levels over the previous month had fallen to "among the lowest on record."
The Mekong springs up from the Tibetan Plateau in China and flows to the South China Sea through Myanmar, Thailand, Laos, Cambodia, and Vietnam. Around 60 million people depend on the river for fishing, farming and transportation.
However, unseasonably low rainfall, along with maintenance work at the Jinghong hydropower station in China, and tests on the Xayaburi dam in Laos, have been identified as causing a massive decline in water levels.
And although rains have recently increased, easing drought conditions and gradually raising water levels, the crisis is far from over.
In June 2019, the average rainfall level in Thailand's Chiang Saen province, for example, was only around two-thirds of the total monthly rainfall for June from 2006 to 2018. Reports have shown that the acute shortage of rainfall is due to El Nino — a meteorological phenomenon in the Pacific Ocean that affects the climate all over the Pacific basin.
