Over the past 150 years, how has fossil fuel consumption affected the carbon dioxide concentrations in the atmosphere?
Eduardwww [97]
Hello!

Fossil fuels are Carbon-based compounds that when heated in the presence of oxygen undergo a combustion reaction to produce thermal energy and gases. The chemical equation for the combustion of a generic Fossil Fuel (C) is the following:

C + O₂ →CO₂

From this chemical reaction, we can see that CO₂ (Carbon Dioxide) is produced, so the consumption of fossil fuels has increased the Carbon Dioxide concentrations in the atmosphere.

Have a nice day!

The Red Sea is widening at a rate of 1.25 centimeters per year. How many years will it take to widen another 812.5 centimeters?
nikklg [1K]

The correct answer is - B) 650.

The Red Sea is a sea that grows in size because it is widening all the time. The rate of the widening is 1.25 centimeters per year, so it is not something that can be easily seen during a normal human lifespan, but over a longer period of time it will have a much different shape, size, and influence in the region. It is located between the African and the Arabian tectonic plates as an elongated thin sea with a northwest-southeast direction.

The widening of the Red Sea is due to the movement of the tectonic plates. Africa is moving towards northwest, and that makes it slowly distance itself from the Arabian plate, thus opening more space for the Red Sea.

In order for the Red Sea to widen another 812.5 centimeters, will be required 650 years, and we can come to the result by simple dividing the required number of the width with the annual widening.

812.5 / 1.25 = 650.
