Answer:

The movement of the water pushes the denser water down, while the upwelling current pushes the less dense water down.

Explanation:

Uowelling currents cause the ocean waters to munch vertically. this movement is done in relation to the temperature and density of the water. This is because this type of current causes cold, nutrient-rich and denser water to be pushed to the surface, while hot, less dense water is pushed down.

The half of the Earth north of the equator is called the: northern, superior, eastern, top

vfiekz [6]

Answer:

northern

Explanation:

Northern Hemisphere is the name to the top part of the Equator, one that goes on the north from it. Earth is divided by the imaginary lined in the middle, and that line is called the Equator. The Northern Hemisphere includes the whole of North America and Europe, the bigger part of Asia, and some parts of Africa and South America.

It is much more populated than the southern hemisphere of the world, especially since countries with huge populations are on it (China, India, US). Most of the counties in the Northern Hemisphere have a colder climate than countries in the Southern Hemisphere. The most upper part of it, Artics, has a really cold climate, and both winters and summers are cold and snowy.

There are nearly 300 million passenger cars in the U.S. The average gas mileage is 25 MPG (miles per gallon) and each car is dri

Natasha_Volkova [10]

Answer:

1.0236 billion metric tons

Explanation:

Given Parameters

Number of cars = 300000000

Average gas mileage per car = 25 MPG

Average distance covered by a car in one year = 10000 miles

CO2 Emission = 8.53 kg/gallon

Derivations from the given parameters,

If the average gas mileage per car is 25 MPG, then the volume of fuel consumed by a car in a year is:

10000 miles ÷ 25 MPG = 400 gallons

The CO2 emission for one car in a year is:

400 gallons × 8.53 kg/gallon = 3412 kg or 3.412 metric tons (note: 1000 kg = 1 metric ton)

The CO2 emission for 300000000 cars in year is:

3.412 metric tons × 300000000 = 1023600000 kg = 1.0236 billion metric tons

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

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.
