The correct answer is C. cosmic rays.<\/p>\n
Cosmic rays are high-energy particles that originate outside the Earth’s atmosphere. They are mostly protons, but also include electrons, neutrons, and heavier atomic nuclei. Cosmic rays are created by supernova explosions, colliding galaxies, and other energetic events in space. They travel at speeds close to the speed of light and can penetrate the Earth’s atmosphere.<\/p>\n
Protons are positively charged subatomic particles that are found in the nucleus of atoms. They are the lightest of the stable hadrons, and are composed of three quarks. Protons have a mass of 1.672621777 \u00c3\u0097 10\u00e2\u0088\u009227 kg, which is about 1836 times the mass of an electron.<\/p>\n
Electrons are negatively charged subatomic particles that are found in atoms and molecules. They are the lightest of the leptons, and are composed of a single electron quark. Electrons have a mass of 9.10938356 \u00c3\u0097 10\u00e2\u0088\u009231 kg, which is about 1\/1836 the mass of a proton.<\/p>\n
