Answer:
A. flood damage is extremely costly due to homes and businesses being built on the flood plain
Explanation:
Floodplain is a waterfront region that is flooded during floods. These areas are very suitable for agriculture due to soil fertility. Such areas develop over the gutter of a valley filled with alluvial soil, over which meanders meander due to the low slope of the river course, which, in flood times, spills over its original bank and floods the adjacent region.
Flooding in this region is natural, but because of the increase in population and the need for expansion of cities, many houses and industries needed to be built in the plains of inunction. In this case, the floods cause a major problem because they cause damage to homes and industries. These losses cause often incalculable economic and emotional damage.
Answer:
From first to last, step wise is given below-
Tropical disturbance < Topical depression < Tropical storm < Wind speed above 74 miles per hour
Explanation:
In order to form a hurricane, at first, the disturbances occur in the tropical region, which is characterized by the occurrence of heavy storm activity over a large area extending 100 miles, that exist for about 24 hours.
Then, with the more favorable conditions, the disturbances alter into stronger storms that spin forming a low-pressure center, and this condition refers to the tropical depression. The required amount of humidity is present in both the upper and lower portion of the atmosphere.
The pressure within the center of the tropical depression eventually gets down, and the air flows inward, thereby forming more stronger winds. With more decreasing pressure, the wind speed drastically increases. Thus, the storm becomes stronger.
When the speed of the wind becomes 74 mph or exceeds, then this type of storm is called a hurricane.
