Low pressure is one of the defining features of a hurricane. Therefore, the correct option is option C.
Hurricanes are intense tropical storms with spiralling winds, copious amounts of rain, and storm surges. These storms can pose a variety of issues when they hit land because they often occur over warm ocean waters close to the equator. Hurricanes leave a path of destruction in their wake, wrecking everything in their path from homes and infrastructure to creating severe flooding and landslides. The unpredictable nature of hurricanes is among their most worrisome features. Although modern technology and meteorological techniques have given us improved storm tracking and prediction systems, it is still challenging to correctly anticipate a hurricane's exact route and intensity.

Build Carbon (6 red protons, 6 grey neutrons, 6 blue electrons) How many
neutrons could an isotope of carbon have?
A. 5
B. 6
C. 7
Answer:
B. 6
Explanation:
Isotope given:
¹⁴₆C
In specie written as this;
Superscript = Mass number
Subscript = Atomic number
To find the protons, it is the same as the atomic number;
Protons = Atomic number = 6
Neutrons have no charges;
Neutrons = Mass number - Atomic number =
Neutrons = 14 - 6 = 8
The number of electrons is the same as the atomic number = 6

Give an example of a chemical reaction during which a single substance breaks
down. *
Answer:
2NaCl(l) => 2Na(s) + Cl₂(g)
Explanation:
Electrolysis of melt NaCl to form sodium (Na) metal and chlorine (Cl₂) gas.
This is a class of reaction called 'Decomposition Rxns'. For what it's worth, there are 6 distinct compound types that undergo breakdown by decomposition. The acronym C O A C H E can help remember them.
C - Carbonates => CaCO₃(s) => CaO + CO₂
O - Oxides of Metals => 2Fe₂O₃(s) => 4Fe°(s) + 3O₂(g)
A - Acids (Oxoacids) => H₂CO₃(aq) => CO₂(g) + H₂O(l)
C - Chlorates, Bromates & Iodates => 2KClO₃(s) => 2KCl(s) + 3O₂(g)
H - Hydroxides => Ca(OH)₂(s) => CaO(s) + H₂O(l)
E - Electrolysis => see above electrolysis of NaCl(l)

How are clouds formed? Simple answer please!
Answer:
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.

Explanation:
How many carbon atoms are represented by the model below?
Answer:
3
Explanation:
Many human activities result in carbon dioxide emissions.
Our carbon footprint is a measure of how much carbon dioxide we each cause to be produced.
(a) Why should we be concerned about our carbon footprint?
(b) Most power stations in the UK burn coal.
Coal was formed from tree-like plants over millions of years.
Suggest why burning wood instead of coal would help to reduce our carbon footprint.
Answer:
: the average human-driven CO2 emissions per year climbed 1.4%
every household makes about 7 tons worth of Co2
A C02 footprints are produced at such high rates and hurts plants and the environment
B coal is a very inexpensive and efficient way to generate electricity. Since its a large quantity of them which still produces alot co2 unlike wood, burning wood doesn't produce as much but it's much harder to ignite and get to last because it takes coal almost 100 degrees and wood takes about 700 degrees

5. Why is it necessary to regularly test the pH of pool
water?
Answer:
To ensure that everyone enjoys using your pool, it is important to keep the swimming pool pH levels in balance at all times. If the pH is too high, it could cause skin irritation and corrode metal parts on the pool. If the pH is too low, it could create a situation where the chlorine in the pool isn't as effective.
Explanation:
Answer:
I don't see multiple choice, so I'll answer this based on what I have learned on my free time.
Explanation:
Usually, when a ton of Urine is in a pool, it can throw off the Ph balance, and can even damage human eyes. Trust me, it's happened to me one time. my eyes burned like fire.
