Bathurst Island is in the Canadian Northwest Territories. The magnetic poles constantly change throughout time. Earth also has a negatively charged surface. When the air is electrically charged, lightning occurs. This is the reason why lightning flashes during thunderstorms.
Earth is the only planet so far known to have life.
Even though other planets may have oxygen, water, and other factors that support life, only Earth has all of these factors. Earth gets all of its energy from the Sun. This is either indirectly or directly. For example, plants make food by making food from the Sun's light, air, and other minerals. This process is known as photosynthesis.
