<span>Point source pollution is a form of contamination found in the air, ground or water that comes from a single identifiable source. It is called point source because it can be traced to one exact point and thus measured. For example noise pollution from a specific factory; light pollution from a light, such as a street light, that shines directly into a house; water pollution from water treatment centers.</span>

Green land is the worlds largest?
Zigmanuir [339]

Answer:

Island

Explanation:

An island is a piece of land that is completely surrounded by water. If a piece of land is a continent, it cannot be technically considered an island. Australia in that sense is not considered an island; it is too big. Greenland is not its own continent but it is still an island so it is the worlds largest island.

Have a wonderful day! :D

1) Using the simple earth energy model we developed in class, calculate the average
andriy [413]

The average temperature of Earth given the solar irradiance is 238.4K.

<h3>How to calculate the temperature?</h3>

The following can be deduced from the information:

Let Earth's albedo =α =0.33

Radius of sun ( Rs) =6.955×10⁵

Value of Boltzmann constant= 5.67×10-⁸

L= 1350

T = average temperature

L= 4σ (Te)⁴ / (1-α)

1 - 0.33 = 4 × 5.67×10-⁸×(T)⁴ / 1350

0.67  × 1350 = 0.0000002268*(T)⁴

(T)⁴ = 3230357142.9

T = 238.4 k

In conclusion, the temperature is 238.4K.

<u>Complete question:</u>

Calculate the average temperature of Earth where the solar irradiance (L) is 1350W/m² and the albedo of Earth is 0.33. Consider Earth to be a perfect black body and the Stefan - Bollzmann constant to be 5.67 × 10^-8 W.
