No, rock material is constantly recycled on Earth as rock is melted into magma.
There is not believed to be a youngest or an oldest planet. They most likely formed simultaneously.
The Earth is estimated to be around 4.5 billion years old based on scientific evidence such as radiometric dating of rocks and meteorites. This age has been determined by studying the decay of radioactive isotopes in rocks and minerals.
No, the oldest rocks on Earth are estimated to be about 4 billion years old and do not contain fossils. Fossils are typically found in sedimentary rocks that formed later, where the remains of plants and animals were preserved.
Water is thought to have formed on Earth around 4.6 billion years ago during the planet's early formation. It likely came from a combination of hydrogen and oxygen that was already present in the materials that formed Earth, such as comets and icy planetesimals. As the Earth cooled and water vapor condensed, water accumulated on the surface in oceans, lakes, and rivers.

No, the Earth is estimated to be around 4.5 billion years old, so these 3.9 billion-year-old rocks formed after the Earth had already been in existence for some time. They provide valuable information about the early history of our planet.
The oldest astronomical bodies are likely the stars in the universe, which formed around 13.8 billion years ago. Next are galaxies, which began forming shortly after the Big Bang. Planets, moons, asteroids, and other smaller bodies in our Solar System are relatively younger, with Earth estimated to be around 4.5 billion years old.

The world population is the total number of living humans on Earth. As of today, it is estimated to number 7.089 billion by the United States Census Bureau. According to current projections, the global population will reach eight billion by 2030, and will likely reach around nine billion by 2050.
Hydrogen is the most abundant element in the universe and was likely present in space before the Earth was formed. Other elements like helium and trace amounts of lithium were also likely present in the early universe before the formation of our planet.
Our planet was formed about four and a half billion years ago, and it is likely that there were mountains from the beginning. The messy process of planetary formation itself, involving the accretion of mass from various smaller bodies, is not likely to produce a perfectly spherical surface.
The Earth is estimated to be around 4.5 billion years old based on scientific evidence such as radiometric dating of rocks and meteorites. This age has been determined by studying the decay of radioactive isotopes in rocks and minerals.
It is most likely formed underground.
Earthquakes have been occurring for millions of years, as a natural result of the movement of tectonic plates beneath the Earth's surface. The first recorded earthquake dates back to as early as 1831 BC in Syria.
Yes. There are estimated to be at least 100 billion planets in our galaxy alone, some of which seem to be similar to Earth. Given those numbers it seems pretty likely that life would have emerged on planets or moons aside from Earth.
Our earth/moon system coalesced from a disk of material orbiting our sun, coming to near its present size some 4.6 billion years ago. The moon itself most likely formed when a mars sized body struck the nascent earth. The debris form that impact would have formed our moon, orbiting much closer than it now does, within just a few thousand years. There are two major periods of impact events recorded on the lunar surface, one about 4.5 billion years ago, and the second about 3.8 billion years ago. There have been other impacts before and since, just not so many or so pronounced.
