Hurricanes are predicted using a Saffir-Simpson Scale. This scale is used to measure the intensity of hurricane most often than not. However, it may be used to identify a hurricane as well. A hurricane is categorised based on the wind speeds.
74 - 95 mph --> category 1
96 -110 mph --> category 2
111 - 129 mph --> category 3
130 - 156 mph --> category 4
157 mph + --> category 5
Typically, the formation of a hurricane occurs when moist warm air if absorbed from the Atlantic or Pacific Ocean and rises. The moisture will then evaporate further rising and heating until the moist air is twisted and circulation high in the atmosphere.
It has gone through four half-lives of carbon-14 (5730 years<span> x 4 = </span>22920 years<span>)
It is 22920 years old.

The soil that occurs in regions with extreme wet and dry seasons is known as "black soil."
Black soil:
- Chernozem is another name for black soil.
- It is largely composed of humus, phosphoric acid, phosphorus, and ammonia.
- Exceptionally small or clay-like particles constitute black soils.
- Deep gaps form during warmer weather, resulting in appropriate aeration.
Black soil characteristics include:
- It is extremely fertile and has a clay-like texture.
- At 25°C, the pH of black soil ranges from 7.2 to 8.5.
- The soil has high levels of potash, calcium, and magnesium but low levels of nitrate and phosphate.
- It is often soft when damp but hardens as it dries.
