D. A rock broke into chunks after being tossed around in a river is considered chemical weathering. In geology, chemical weathering is the process by which rocks are gradually broken down through chemical interactions, frequently producing a totally distinct substance.
What are chemical weathering and state three chemicals produce weathering?
Water and minerals interact in this process, causing a variety of chemical reactions that change the rocks. As the mineralogy of the rock adapts to the near-surface environment, chemical weathering is a gradual and continual process. The main minerals that made up the rock's foundation give rise to secondary minerals. The two chemical reactions that happen most frequently in this are oxidation and hydrolysis.
Oxidation, hydrolysis, and carbonation are the primary chemical reactions involved in chemical weathering. Hydrolysis is a reaction with water, carbonation is a reaction with CO2 to generate a carbonate, and oxidation is a reaction with oxygen to form an oxide. In order to alter the composition of rocks, chemical weathering requires the interaction of rock with mineral solutions (chemicals).

Explain how a country's youth dependency ratio may change if its
population grows mainly through natural change is negative.
But when birth rates ratio continue to fall, dependency ratios inevitably rise as the proportion of people who are working age starts to diminish and the number of youth elderly people keeps rising.
The dependency ratio calculates the proportion of dependents who are not of working age to the total population. Because people are living longer in the west, we are observing an increase in the dependence ratio. As a result, there are more persons over 65 and dependency ratios are rising. The population ages 0 to 15 is divided by the population ages 16 to 64 to calculate the youth dependency ratio.

In one-point perspective, parallel lines converge at a single vanishing point on the horizon.
Perspective drawing is a technique for creating the illusion of linear depth. As objects get further away from the viewer, they appear to decrease in size at a constant rate. The box in the sketch below looks solid and three-dimensional because of the use of perspective.
One-point perspective is a method of drawing that shows how things seem to get smaller and smaller as they get further away, converging towards a single 'vanishing point' on the horizon line. This is a way of drawing objects on a flat sheet of paper (or other drawing surface) so that they look three-dimensional and realistic.

According to the article how can we reduce water scarcity? the essays underneath.
About two-thirds of the world’s population faces water scarcity for at least one month during the year. The growing risk of worldwide water shortages is worse than scientists previously thought, according to a new study.
About 66 percent, which is 4 billion people, of the world’s population lives without sufficient access to fresh water for at least one month of the year, according to a new paper published Friday in the journal Science Advances (Links to an external site.).
Previous studies calculated a lower number, estimating that between 1.7 and 3.1 billion people lived with moderate to severe water scarcity for at least a month out of the year.
Scientists, led by Dr. Arjen Hoekstra (Links to an external site.) of the Netherlands’ University of Twente, used a computer model that is both more precise and comprehensive than previous studies have used to analyze how widespread water scarcity is across the globe. Their model considers multiple variables including: climate records, population density, irrigation and industry.
“Up to now, this type of research concentrated solely on the scarcity of water on an annual basis, and had only been carried out in the largest river basins,” Hoekstra said (Links to an external site.) in a statement. “That paints a more rosy and misleading picture, because water scarcity occurs during the dry period of the year.”
“The fact that the scarcity of water is being regarded as a global problem is confirmed by our research,” Hoekstra added. “For some time now, the World Economic Forum has placed the world water crisis in the top three of global problems, alongside climate change and terrorism.”
Severe water scarcity happens when consumption is twice as high as available resources, according to the study’s researchers. Consequently, half of those suffering from water scarcity are in the world’s two most populous countries — India and China — where demand is high.
High-scarcity levels are also widespread in areas with significant irrigated agriculture (like the Great Plains in the United States) or low natural availability of fresh water (like the Arabian Desert) where populations are also relatively dense, according to the study. Similar patterns exist in the south and western United States where heavily populated states like California have been in a drought for years. (Links to an external site.)
The consequences of water scarcity can result in economic losses due to crop failure, limited food availability and poor business viability, and can threaten environmental biodiversity. When faced with scarcity, areas in need of water often resort to pumping groundwater (Links to an external site.), which can permanently deplete the supply.
Water shortages have also precipitated or heightened the potential (Links to an external site.) for global conflicts in places like the Middle East and Africa.
“Freshwater scarcity is a major risk to the global economy (Links to an external site.), affecting four billion people directly,” Hoekstra told The New York Times. “But since the remaining people in the world receive part of their food from the affected areas, it involves us all.”
Despite the grim findings, the study recommends ways to reduce scarcity, such as increasing reliance on rain-fed rather than irrigated agriculture, improving the efficiency of water usage and — perhaps the most challenging for humans — sharing what’s available. The researchers point out that for these solutions to be effective, governments, corporations and investors will need to cooperate.
