The formation of a hurricane is complicated, but basically, it depends on 3 factors : First, you need warm water, at least 80 degrees. The second ingredient is moist air.
Natural disasters such as hurricanes, tornadoes, and floods are examples of density independent factors since they are not tied to population size. For example, predation, competition, and food availability are all impacted more adversely by density dependent factors than they are by other factors such as size and density of the population.
Hurricanes are a density independent factor because they generate the same effect regardless of the current population density. A population of field mice increases after a farmer leaves his field unharvested for a season.
The fact is, hurricanes increase the death rate for many species, while some species see a highly increased birthrate after the destruction. During a hurricane, winds increase to dangerous speeds, tearing large trees out of the ground.
What are the characteristics of Hurricane?
Hurricanes are one of nature’s most powerful storms. They produce strong winds, storm surge flooding, and heavy rainfall that can lead to inland flooding, tornadoes, and rip currents. What is a hurricane?
Hurricanes, known generically as tropical cyclones, are low-pressure systems with organized thunderstorm activity that form over tropical or subtropical waters. They gain their energy from warm ocean waters.
We discovered large-scale conditions in the Atlantic and the Caribbean Sea will determine how active or inactive a hurricane season will be. The number of storms in an Atlantic hurricane season depends on the large-scale atmospheric and oceanic environment in the areas where storms develop, in the tropical North Atlantic Ocean and the Caribbean Sea.
What happens when a hurricane approaches land?
When a hurricane approaches land, tremendous damage can occur to coastal cities and towns. Hurricanes impact natural environments along a coast too. Huge amounts of beach sand are moved from place to place. Even large boulders can be carried in the powerful surge of ocean water. High winds can topple trees.
How is a volcano a density independent factor?
A volcano is a density independent factor in that the cataclysm destroys trees, which are a potential food source. Lava and soot can kill certain species and lower the population. Volcanic discharge can pollute local drinking water, forcing animals to find clean sources of water elsewhere.
Typically, density dependent factors are biological factors used by the population as a resource. These can be things like food, shelter, or other limited resources. Density dependent factors cause variable changes in the population as its density changes. When the population is small, these factors typically favor increased birth rates.
What are density independent factors?
Density independent factors vary depending on the population, but always affect the population the same regardless of its size. There are many common density independent factors, such as temperature, natural disasters, and the level of oxygen in the atmosphere. These factors apply to all individuals in a population, regardless of the density.
Do honeybees have density independent factors?
Density independent factors for honeybees include things like weather and temperature. Regardless of the current size of their population, bees need the temperature and weather to stay within certain ranges. If the weather does not stick to this pattern, many bees will die.
How does density affect the Bees?
However, the bees also face a number of density dependent factors. For instance, their food source and its effects on their population is directly related to the size of their population. If they have a small population, there will be plenty of food for all and the bees will grow.
