Answer:
Drought is a condition, not a hypothesis. Drought is the lack of rain, or evaporation in excess of precipitation.
The CAUSE of drought is a multi-pronged hypothesis. It can be due to cyclic changes in ocean temperature (El Niño/La Niña). It can be due to rain shadow downwind of a mountain range. It can be due to fluctuations in the sun’s brightness. It can be the result of urban sprawl and resulting shifts in upwind evaporation/transpiration. It can be the result of climate bands shifting in response to changing atmospheric composition. It can be the result of agricultural practices upwind. It can be just bad luck, with a location consistently not being the whatever-percent chance of where it’s raining.

Answer:
After three half-lives, it is 7:1
Explanation:
- The rate at which the decay of the radioactive isotope is said to be half-life and is represented as the half-life of the atoms and the matter to disintegrate itself.
- The two radioactive isotopes are K 40 and Ar 40. After the K-Ar dating, they contain minerals such as the clay mica and the temphra minerals and Half-life of the K 40 is 1.3 more than 100,000 years i.e 10x9 years for Ar 40.
- <u>Thus the K 40 has to divide as three half-lives have passed if the ratio of argon to potassium atoms is 7:1. At the end of one half-life, the ratio of the number of argon to potassium atoms is 1:1. and two half lives its 3:1 thus after the third half-life it becomes as 7:1.</u>
