There was an ozone atmosphere on primitive Earth, but not an ozone layer which was formed further on. The primitive atmosphere on the surface of the Earth mostly composed by ozone was pushed upwards by the oxygen formed by dead organisms.
That primitive ozone atmosphere on the surface of the Earth protected the forming microorganisms from the UV radiation.

What type of change is matter destoryed?
When matter is destroyed, it undergoes a chemical change, where bonds between atoms and molecules are broken down to form new substances. This is different from a physical change where the form of matter changes without altering its composition.
Why can UV break apart molecules and IR only speeds up the molecules vibrations?
Ultraviolet waves have shorter wavelengths than Infrared waves. Since the relationship between wavelength and frequency is inversely proportional, UV waves have a much higher frequency than IR waves. IR waves have a frequency around 1012 Hertz, while UV waves' frequencies are around 1018 Hz. Thus, UV waves are more powerful than IR waves and can cause binds between molecules to break much more easily than IR waves.
What is the thermosphere's job in the atmosphere and what would happen if there was no thermosphere?
Thermosphere shields us from radiation that the sun emits. That is its main job. It serves as a protective shield against the x-ray and UV radiation being emitted by the sun and keeps earth's temperature in which living things can survive. Without it, the earth will be destroyed by radiation heat.
How do you decrease the number of molecules in a glass of water without changing the number of water molecules?
If the water is impure, you could remove the impurities. If the water is pure, it's impossible to decrease the number of molecules without changing the number of water molecules, which would be the only kind of molecules present in that case.
What is transmitted radiation?
Transmitted radiation refers to the portion of radiation that passes through a material without being absorbed or scattered. This can include various types of radiation such as light, x-rays, or gamma rays. The amount of transmitted radiation depends on the material's composition and thickness.
What is it called when there is a transfer of heat through space without molecules?
The transfer of heat through space without the need for molecules is called radiation. Radiation is a form of energy transfer that does not require a medium to propagate and can occur through vacuum.
Is the sun the source of energy in most energy resources?
The Earth has two sources of energy, the sun's radiation and heat from inside the Earth. The sun is most important and life could hardly exist except at a very primitive level without it.
Why do mobile phones need radiation to work?
because without radiation it wouldn't have access to web without it
What does it mean for heat to be transferred by radiation?
Energy is transferred when molecules absorb electromagnetic waves.
Is infared radiation ionic or non ionic?
Infrared radiation is non-ionic because it consists of electromagnetic waves that do not involve the transfer of charged particles like ions. Instead, it represents a form of energy that is emitted and absorbed by molecules without causing any ionization processes.
Official records will not be destroyed without the specific authority of whom?
Official records will not be destroyed without the specific authority of the Archivist of the US.
How is heat transferred from one molecule to another?
Heat is transferred between molecules through three main mechanisms: conduction, convection, and radiation. In conduction, heat transfer occurs through direct physical contact between molecules. Convection involves the transfer of heat through the movement of fluids. Radiation is the transfer of heat through electromagnetic waves, without the need for a medium.
What does it mean for a molecule to be transparent to radiation?
A molecule is transparent to radiation when it allows radiation to pass through it without being absorbed or scattered. In other words, the radiation can travel through the molecule with minimal interaction.
Can a phone without a sim cause radiation?
Yes, mobile phones without sim cards can emmit radiation because of a microchip contained in it.
What is the movement of heat without matter to carry it is called what?
The movement of heat without matter to carry it is called radiation. Radiation is the transfer of heat energy in the form of electromagnetic waves, such as infrared radiation from the sun to Earth.
Can fertilizaton occur without the presence of water?
Of course it can. Only primitive types need water
Which passes through glass without a problem infrared or ultraviolet radiation?
Infrared radiation can pass through glass without a problem. Ultraviolet radiation, however, is partially absorbed by most types of glass and therefore cannot pass through as easily.
