Answer:

sun is bigger than earth is  13.9 cm

Explanation:

given data

radius of sun = 700,000 km

radius of earth = 6500 km

to find out

how big is the sun

solution

we know here

scale 1 to 10 billion is

scale = \frac{1}{10*10^9}

so here

we know that scaled diameter = actual diameter × scale   .................1

so for earth

scaled diameter of earth = 2 × 6500   × \frac{1}{10*10^9}

scaled diameter of earth = 1.3 × 10^{-6}

and

scaled diameter of sun = 2 × 700,000  × \frac{1}{10*10^9}

scaled diameter of sun =  1.4 × 10^{-4}

so

sun is bigger than earth is 1.4 × 10^{-4}  - 1.3 × 10^{-6}

sun is bigger than earth is 0.000139 = 13.9 cm

Define drought and desertification ​
Alex
A drought is an event where there are shortages of water supply. The water in question can be atmospheric, surface water or ground water. A drought can last for months or years, but sometimes for a few weeks. It can cause big problems and crises in a lot of countries.
Desertification is the process by which fertile land becomes desert typically as a result of drought, deforestation, or inappropriate agriculture. Desertification is a big problem in a lot of places, because deserts are getting bigger and people are loosing good land that can be used because of it.
