When the primary cosmic rays from space enter Earth's atmosphere, they immediately begin to collide with other particles and then those collide with other atoms, and so on, creating a "shower" of particles, which can be several kilometers wide. The energy with which they encounter the atmosphere is such that the collision can split atoms, nuclei, and other particles, which secondary particles then can decay abd enit radation as part of the shower; these can reach the Earth's surface as protons, neutrons, antiprotons, electrons, alpha particles, pion, muons, etc., and electromagnetic radiation like x-rays.

Does earth's distance from the sun affect the season's?
No it does not. Earth's seasons are affected by Earth's tilt. The earth is tilted 23.5 degrees so seasons are created by the sun's direct rays hitting different parts of the earth. Summer in the northern hemisphere starts when the sun's direct rays hit the tropic of cancer. winter occurs in the northern hemisphere when the sun's direct rays hit the tropic of capricorn. fall and spring begin when the sun's direct rays are at the equator. (By the way, summer in the norther hemisphere occurs when the earth is farthest from the sun)
Why temperature are different from continent to continent?
The sun is the major affecter in temperature on Earth. Since the sun's rays are not directly shinning on every point of Earth, temperatures differ. The sun's rays only directly hit between the Tropic of Cancer and the Tropic of Capricorn.
Why is it more difficult to get a suntan during the winter months?
It is more difficult to get a suntan during the winter months because the rays of the sun are not hitting the part of the earth where you are trying to get a sun tan less directly and they are weaker. This is because the earth is tilted at a 23.5% tilt. The equator is warmest because most of the rays of the sun hit there most of the time. When it is winter the side of the earth is tilted away from the sun, and the rays of the sun have to travel further to get there.
Why is hotter in summer than in winter in some countries?
More of the Sun's rays directly hit a particular region on Earth during the summer than during the winter.
Fragment that enters the earths atmosphere but does not hit earth?
Meteor. Meteorites are the ones that do hit Earth.
What are secondary cosmic rays?
Secondary cosmic rays are the product of collisions with primary cosmic rays. Primary ones are the kind that arrive from space and hit earth - typically air molecules in the upper atmosphere, which creates (and transfers its energy to) other particles, often creating a shower ('air shower') of secondary particles, also of high energy. Even though these products are results of collisions from within the Earth's atmosphere, they are still referred to as cosmic rays, although given the name "Secondary" cosmic rays. Note that secondary cosmic rays' composition or relative composition can differ from the cosmic rays arriving from space; particularly as new particles like muons and pions can be generated.
Do any gamma rays at all make it to the surface of Earth?
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.
What is the percentage of UV rays that hit the earth?
about 7% of the UV rays hit the earth.
When light rays hit a smooth surfer the rays are scattered?
A shadow is formed.
What kind of ray hit the earth?
Many Rays hit the Earth but the most are UV rays because the Earth is always in the Sun's path so...yea
What protects a rocket from cosmic rays?
Scientists and engineers have created some type of foam that's several inches thick. Once the cosmic rays hit the foam, it is able to surround the ray and slow it down, thus protecting the rocket.
Where do astrophysical neutrinos come from?
They originate from nuclear reactions, such as those that take place in a star, when cosmic rays hit atoms and in supernovae.
What does the angle of earth have to do with the seasons?
it affects the angle at which the sun rays hit the earth
Do the tangent rays hit the equator on june21?
Tangent rays will hit any part of the earth on any day at sunrise and at sunset.
How long does the sun from the moon take to hit earth?
The rays from the sun take 8 minutes to hit the earth
What is angle of insulation?
It is the angle at which the sun's rays hit the earth
What season do sun rays hit the earth the most?
