The proton is a subatomic particle found in the center of the atom.
In the physical sciences, subatomic particles are particles much smaller than atoms. There are two types of subatomic particles: elementary particles, which according to current theories are not made of other particles; and composite particles. Particle physics and nuclear physics study these particles and how they interact.

Answer:old earth:
At its beginning, Earth was unrecognizable from its modern form. At first, it was extremely hot, to the point that the planet likely consisted almost entirely of molten magma. Over the course of a few hundred million years, the planet began to cool and oceans of liquid water formed.The early Earth's atmosphere had a very low concentration of oxygen compared to today. 2.4 billion years ago, the oxygen concentration in the atmosphere was less than one part per billion and the iron concentration in the ocean was much higher than today.At its beginning, Earth was unrecognizable from its modern form. new earth:
"Today's Earth (TE)" is JAXA's land surface & river simulation system developed under the joint research with University of Tokyo. The system distributes & visualizes various hydrological products and their magnitudes for disaster monitoring and hydrological research.
The early Earth was very different from our Earth today. The early Earth experienced frequent impacts from asteroids and meteorites and had much more frequent volcanic eruptions. There was no life on Earth for the first billion years because the atmosphere was not suitable for life.
