The Sahara Desert experiences cycles of greening approximately every 20,000 years due to changes in the Earth's axial tilt and orbit, known as Milankovitch cycles. These variations affect the distribution of sunlight, leading to increased rainfall and the expansion of vegetation in the region. During these periods, the once arid landscape can support grasslands and forests, creating a more hospitable environment for wildlife and human habitation. As the cycles progress, the climate shifts back to arid conditions, returning the Sahara to its desert state.

20000 - 20000(.10)(5) = $10000 **That is assuming there was no real damage done!
To calculate the interest earned on an investment of $20,000 compounded annually at a rate of 5% for 2 years, you can use the formula for compound interest: ( A = P(1 + r)^n ), where ( A ) is the amount of money accumulated after n years, ( P ) is the principal amount, ( r ) is the annual interest rate, and ( n ) is the number of years. Plugging in the values: ( A = 20000(1 + 0.05)^2 = 20000(1.1025) = 22050 ). The interest earned is ( A - P = 22050 - 20000 = 2050 ). Thus, the interest earned over 2 years is $2,050.
kid, you dont.
The Sahara used to be green now it is a Desert. I'm still looking for more. Does that help at least?
That seems to change every few years. Sometimes it is the Sahara Desert but recently the Mojave Desert has overtaken the Sahara.
After 5 years, 20000 at 7% per annum compounded semiannually will be 20000*(1 + 0.5*7/100)2*5 = 20000*(1.035)10 = 28211.98
20000 days on Earth is equal to roughly 54.8 years.
The Sahara is about 2.5 million years old.
