Imagine Earth's magnetic field suddenly disappeared. What kinds of problems could arise for life on Earth? Explain. Class 8

Answer:

If Earth's magnetic field disappeared, high-energy particles like cosmic rays and solar wind would directly hit the atmosphere, potentially deplete the ozone layer and allow harmful UV rays to reach the surface. This might damage living cells, increase skin cancer risk, and harm animals like birds and turtles that use the field to navigate. It could also disrupt satellites, power systems, and communication.
