My physics book says that the Earth has a net charge of zero. How is this possible with all those particles coming in from the sun etc, I would of thought it would accumulate a charge somehow.
Earth Zero Net Charge refers to the concept that the Earth as a whole has an overall neutral electrical charge. This is due to the equal balance of positive and negative charges on the planet.
The Earth's net charge is determined by measuring the amount of positive and negative charges present on the planet. This can be done using tools such as satellites and ground-based sensors.
Earth's net charge is important because it plays a role in the planet's overall electrical and magnetic fields. These fields are essential for sustaining life on Earth and protecting us from harmful solar radiation.
Yes, Earth's net charge can change over time due to natural events such as lightning strikes and solar storms. However, these changes are usually very small and do not significantly impact the overall net charge of the planet.
Earth's net charge does not have a direct effect on humans. However, the planet's electrical and magnetic fields, which are influenced by the net charge, play a crucial role in sustaining life on Earth and facilitating technologies such as GPS and telecommunications.
