Question

What changes to Earth’s environment would occur when the magnetic poles reverse?

Expert Solution

Introduction

Due to the rotating denser metallic core at the center of the Earth, there is generation of the magnetic field around it. These magnetic fields are strong enough to deflect the radiations in the outer atmosphere. Magnetic reversal events have happened in the past, where there is the interchange of pole directions.

Explanation

Increased cosmic radiation levels if magnetic field reversal occurs on Earth, as the magnetic field weakens during the reversal event. These harmful cosmic radiations will enter the Earth's atmosphere and affect the environment. The chances of diseases like cancer will increase, impacting agriculture and plant growth. The auroras will be visible in the lower latitudes' night sky.
