How long is the earth’s precession estimated to last? 6,000 years
13,000 years
23,000 years
100,000 years

Answer;

The most appropriate answer from the choices given would be 23,000 years

Explanation;

The period of Earth's precession is about 26,000 years. In other words, it takes 26,000 years for the axis to trace out the cone one complete time. Earth's spin axis also precesses.

Earth's precession is caused by the gravitational pull of the Sun and the Moon on the Earth.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
