Option B is correct because cosmic rays, which are energetic particles originating from outer space, are indeed affected by Earth’s magnetic field. As they enter Earth’s atmosphere, they can be deflected or redirected by the magnetic field lines, influencing their paths and interactions with particles in the atmosphere. Options A, C, and D are incorrect as cosmic rays consist of various particles such as protons, electrons, and atomic nuclei (not solely photons), they can travel at speeds approaching the speed of light, and they originate from various sources beyond our solar system, including distant galaxies, supernovae, and other astrophysical phenomena.

Earth's Magnetic Field Deflects Cosmic Rays
Cosmic rays are high-energy particles, mainly protons, that travel through space at nearly the speed of light. One of the key characteristics of cosmic rays is that they are deflected by Earth's magnetic field. This is due to the fact that cosmic rays are charged particles, and as they enter Earth's magnetic field, they experience a force that causes them to change direction. This deflection phenomenon is known as geomagnetic cutoff.
Importance of Earth's Magnetic Field
Earth's magnetic field plays a crucial role in protecting our planet from the harmful effects of cosmic rays. By deflecting a significant portion of incoming cosmic rays, the magnetic field helps to shield Earth's surface and its inhabitants from the high levels of radiation that cosmic rays carry. This protection is essential for maintaining a habitable environment on Earth.
Impact on Technology and Astronauts
The deflection of cosmic rays by Earth's magnetic field also has implications for technology and space travel. For example, spacecraft traveling beyond Earth's magnetic field are exposed to higher levels of cosmic radiation, which can pose risks to both the spacecraft and its occupants. Understanding how cosmic rays interact with Earth's magnetic field is therefore crucial for ensuring the safety of astronauts and the success of space missions.
In conclusion, the statement that cosmic rays are deflected by Earth's magnetic field is true. This deflection phenomenon is a key characteristic of cosmic rays and has important implications for both the protection of Earth and the safety of space exploration.
