Answer: C.
Air masses that are hot and dry, and are responsible for heatwaves of summer in the western half of the United States.
Explanation: Air masses have fairly uniform temperature and moisture content in the horizontal direction (but not uniform in vertical). Air masses are characterized by their temperature and humidity properties. The properties of air masses are determined by the underlying surface properties where they originate.
Air that stands over the Caribbean Sea, for example, becomes a warm, humid maritime tropical air mass, while air that lies in the Arctic regions of northern Canada takes on the cold and dry characteristics of its surroundings and becomes a continental polar air mass.
e largest of the continents is Asia, which covers about 17.2 million square miles
Answer: Earth reinforcing
Explanation: Earth reinforcing is a method of strengthening the soil/ground when constructing foundation by combining materials such as steel or concrete to the soil. It is especially useful for the construction of conventional retaining walls or mining structures.
Historically, steel nets were used on areas with soft clay, such as sea beds. Some materials used now include Geonets and geogrids.
Answer:
The population of the city will reach 2 million people in 2025.
Explanation:
The city in question has one million people. The doubling time of the population is estimated at 25 years. Double of one million is two million, and with the population being one million in 2000, 2025 will be the year when the city will have a population of two million since the doubling time is 25 years.
s Doubling of the population in 25 years is not something that happens rarely, but it mostly happens in smaller cities or towns, as the population needed for doubling the preexisting one shouldn't be that large. A city of one million people to double its population in just 25 years is another story. Such a scenario will mean a highly centralized region, with most of the region getting depopulated, while the city in question gets a huge amount of new residents, causing a lot of urbanistic challenges.
