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.
Answer:Fixation - Fixation is the first step in the process of making nitrogen usable by plants. Here bacteria change nitrogen into ammonium. Nitrification - This is the process by which ammonium gets changed into nitrates by bacteria. Nitrates are what the plants can then absorb
