No.
It doesn't
By and large, aside from the messes left by the human infestation, yes. The Earth does look much the same as it did a million years ago. The Atlantic ocean might be a little wider, the Pacific a little narrower, the water level a little higher, but the place looks pretty much the same.
A year on our planet is 365.25 Earth days. Other planets take more or less time depending on their orbital distances from the Sun. Mercury - 88 Earth days Venus - 225 Earth days Mars - 687 Earth days Jupiter - 11.86 Earth years Saturn - 29.46 Earth years Uranus - 84 Earth years Neptune - 164.8 Earth years Pluto (now a dwarf planet) - 247.7 Earth years
Because they were made the same time as the Earth from the same materials. And, since they have basically been frozen in time in outer space, they can tell us a lot about the composition of the Earth. The materials on Earth are constantly being recycled and nothing remains from the birth of the Earth, so that is why we look to outer space and the meteorites that fall to Earth to give us clues to its origin.

No. Earth grew over the course of millions of years as more material was added to it.
No, the Earth has undergone significant changes over the millions of years due to processes like plate tectonics, erosion, and climate change. Continents have shifted, mountains have formed and eroded, and sea levels have fluctuated, resulting in a continuously evolving appearance of the Earth's surface.
The water cycle
The sun is millions of times bigger than the moon, but the moon is many times closer to Earth.
Lower .
There were no cities millions of years ago.
YES
Because it's further away from the Earth.
No! It's logical to conclude that small traces of water may have entered the earth's atmosphere through debris coming from space but on a question whether we've been using the same water in circulation since millions of years ago,Definitely yes!
No, but it once was. Coal is produced by pressure in the earth and it once was was plants and animals millions of years ago. Oil is produced the same way.
The ones that are on the Moon will look the same. The ones that are on Mars will look very much the same. The ones that are on Earth will look completely different, or they may be gone altogether.
