The Dead Sea

In our latest math project, we explored linear equations. More specifically though, we looked at rising and lowering water levels. We split up into partners and I worked with Morgan to research the impact of climate change on the Dead Sea. The Dead Sea, located between Israel and Jordan, has been drying up at a very rapid rate for hundreds of years.

Driving question:

How much area (of water) does the Dead Sea lose every year and how long would it take for it to lose all of its area?

Information We Started With

The current area of the Dead Sea is 605km^2

-In 1930 it’s area was 1050km^2

-Meaning, 445km^2 of area was lost in 88 years

Our Equation

Using this information, we calculated the rate of change using a slope equation. In this equation,

Y = Area lost

X = Years

M = Rate of change (Area lost over years)

B = amount lost to start (In this case, 0)

Therefore, our equation is Y = 445/88 X + 0

Our Graph

Why is This Happening?

This is happening for a couple of reasons. First of all, the Dead Sea has a very high salt content, which causes it to be dryer than normal seawater. Second, and more importantly, climate changed has caused more and more water to evaporate at a very fast rate.

In Conclusion

-To lose 1050 km^2 ( the original amount) it would take ~207.64 years

-To lose 605 km^2 (the current amount) it will take ~ 119 years

-This means that it loses around 5.057 km^2 per year
