klasskru [66]

$\Large{\underline{\boxed{\mathfrak \pink{Question:-}}}}$

Global climate change is most likely the result of _______. Environmental issues: Select the best answer from the choices provided.

A. Increased carbon dioxide in the air.

B. Diminishing natural resources.

C. Decreased Oxygen and carbon dioxide in the atmosphere.

D. Biodiversity.

$\Large{\underline{\boxed{\mathfrak \pink{Answer:-}}}}$

$\normalsize\star\textsf{Correct \: Option:-}$

$\qquad\bullet$ Option"A" is correct: Increase in Carbon dioxide in Air.

$\normalsize\star\textsf{Related \: Questions:-}$

a.) How global climate change is related to the increase of carbon dioxide in Air ?

$\qquad\bullet$ The Increase of Carbon dioxide in Air results in increase of Global warming(Green house effect).

$\qquad\bullet$ Green house effect : A building mostly made of glass for growing or shelter in the delicate plant is called greenhouse. the glass walls of greenhouse allows sun rays to pass through the interior.However, reflected back infrared rays are not allowed to escape through the glass walls. Carbon dioxide gas and water vapours present inside the glass house further trap the heat and make the greenhouse warmer than the outside air.

$\qquad\bullet$ The atmosphere cover around the earth ,acts similar to the glass walls of greenhouse. the air cover solar radiation to pass through it to the Earth’s surface, and prevent the long wave infrared radiation to escape into the space.Gases such as Carbondioxide,Nitrogen oxide,CFCs,ozone are the Greenhouse gases and among all of them "Carbon dioxide" is the most important gas.These greenhouse gases trap the heat reflected by the earth.

$\qquad\bullet$ The heating up of the atmosphere leads to an increase in Earth's temperature.This phenomenon is called " Global warming or Green house effect.

b.) What are the effects of Global warming?

$\qquad\bullet$ Increase in earth temperature will cause a change in weather and precipitation patterns on the earth.

$\qquad\bullet$ As we know the fact that " An increase of less as 1°C in Earth's temperature can lead to melting of polar ice caps and consequent rise in sea level".The sudden rise of sea level can submerge a number of major cities of the world which are located along the coasts.

$\qquad\bullet$ Global warming poses a threat of recurrence of "Dust Bowl condition of 1930's".Dust Bowl is an area where vegetation has been lost and soil reduced to dust making it suspectable to erosion.

$\qquad\bullet$ One of major danger of global warming is " Methane burp"which is caused by the melting of Methane hydrates in permafrost of polar ice caps & on the sea floor.

Using the DTM above, what occurs to a population during Stage 2?

Lelu [443]

Answer:

During stage 2, the death rate drops while birth rates remain the same.

Explanation:

The first option is not correct because this is a characteristic of the later stages in the DTM.

The second option is correct because, during stage 2, the death rate drops because of improved living conditions and healthcare, while the birth rates remain the same, leading to population explosion.

The third option is not correct because this is a characteristic of the last stage of the DTM.

The fourth option is not correct because such actions are usually taken in stage 3.
