The statement is - True.
The solvent do contains chlorofluorocarbons (CFC) and hydrochlorofluorocarbons (HCFC) which evaporate and enter the atmosphere. Because they are very light, the CFC and HCFC manage to get very high into the atmosphere, reaching the ozone layer in the stratosphere. They are actually the two substances that are the most damaging to ozone layer, as once they get in touch with it, they break down its structure, thus creating the ozone holes.
The ozone is crucial for the survival of the living organisms on the Earth as it is the layer that manages to stop most of the ultraviolet rays form the Sun to reach the surface. Because of that, these two substances have to be replaced quickly as the ozone layer is becoming more and more damaged, and that can eventually lead to a tragedy.
The answer is the Sahara Desert.
Answer:
b)-2.4% year
Explanation:
The population growth can be calculated by the following equation.
In which is the population in t years from now, is the population in the current year and r(decimal) is the growth rate. is the Euler number.
The current population of South Korea is 50 million, so
2750 is 2750 - 2019 is 731 years from now. So we have that . The population is going to be extinct, so .
So, we can replace the values of and t in the equation, and see for which growth rate .
a) 0.012 % year
This is a positive growth rate, which means that the population will not be going extinct. So this is not the alternative
b)-2.4% year
Population of 1 person, basically extinct. This is the correct answer
c)-0.01% year'
Population still at 24 million, it does not goes extinct.
d)-0.012% year
Population still at almost 21 million, it does not goes extinct.
