They're largely absorbed by air.
The Earth's magnetic field acts as a shield, deflecting charged particles (cosmic rays) away from the surface. This helps reduce the intensity of cosmic rays reaching the Earth's surface. However, cosmic rays can still penetrate the atmosphere at higher latitudes where the magnetic field is weaker.
Cosmic rays are continuously present in space - regardless of what day (or year) it is. Luckily, we are protected from cosmic rays on the surface of the Earth by the Earth's atmosphere and magnetic field. A small amount of comic rays can still reach the Earth's surface - particularly at higher altitudes.
Almost all gamma rays are absorbed by the Earth's atmosphere, or deflected by the magnetosphere, but some do manage to get through. Those that reach the surface of the Earth are mostly secondary comic rays, which are produced when gamma rays or primary cosmic rays hit the top of the atmosphere.
Solvents take away the ozone layer, letting UV rays reach the Earths surface easier.

Cosmic rays are high-energy particles, such as protons and atomic nuclei, that travel through space at nearly the speed of light. They can originate from sources such as supernovae, black holes, and other high-energy phenomena in the universe. Cosmic rays can impact Earth's atmosphere and even reach the surface, where they can be detected by instruments on the ground.
There's a considerable (overlapping) range of frequencies for both gamma rays and cosmic rays, but the upper reach for gamma rays is considered to be higher than that for cosmic rays, all the way to 10^30Hz.
No, it is not possible to stop cosmic ray showers. They are high-energy particles from outer space that constantly bombard Earth's atmosphere. However, Earth's atmosphere acts as a shield, absorbing and deflecting most of the cosmic rays before they reach the surface.
Most of the visible light and some of the ultraviolet and infrared radiation from the sun pass through the atmosphere and reach the Earth's surface. Other forms of radiation, such as gamma rays and X-rays, are mostly absorbed by the atmosphere and do not reach the surface.
Cosmic rays can enter Earth through Mars because Mars has a thinner atmosphere than Earth, allowing cosmic rays to penetrate more easily. The lack of a strong magnetic field on Mars also means there is less protection against cosmic rays compared to Earth. This makes Mars a potential gateway for cosmic rays to reach Earth.
Earth's magnetic field created by earths magnets deflects cosmic rays which damage our biosphere.
Ultraviolet (UV) rays from the sun travel through the vacuum of space and reach Earth’s atmosphere. While some UV radiation is absorbed by the ozone layer, which protects the surface from harmful effects, a portion still penetrates through. This allows UV rays to reach the Earth's surface, contributing to processes like photosynthesis and skin tanning, but also posing risks such as skin cancer and eye damage.
