The formation of basic elements like hydrogen and helium occurred approximately 13.8 billion years ago during the Big Bang.
The Archean Eon spans from the formation of the Earth around 4.6 billion years ago to approximately 2.5 billion years ago. This eon is marked by the formation of the first continents, the emergence of life in the form of prokaryotic cells, and the development of the Earth's atmosphere.
The Earth cooled enough for liquid water to form around 4 billion years ago, shortly after its formation. This allowed for the creation of the Earth's oceans and laid the foundation for the development of life.
The formation of the solar system occurred around 4.6 billion years ago. The process began with the gravitational collapse of a giant molecular cloud and eventually led to the formation of the Sun, planets, and other celestial objects.
Precambrian time spans from the formation of the Earth, about 4.6 billion years ago, to the beginning of the Phanerozoic Eon, about 541 million years ago. It is the longest eon in Earth's history.
Fossils are bones and remenants of organisms that lived a long time ago. I guess the bones of what were once organisms and bacteria that helped it to decay helps to form a fossil....
a long time ago!!
Sodium has been present on Earth since the planet's formation around 4.6 billion years ago. It is one of the most abundant elements on Earth and can be found in various minerals, seawater, and even in our own bodies.
Its very own fuel: made up of hydrogen, carbon, and a few other elements. Stars were given 4 basic elements hydrogen carbon something something look it up. They used these to make new elements: all the elements on the periodic table. You are made up of elements created by stars long ago.
The inside of the Earth is hot due to the heat generated from the decay of radioactive elements and the residual heat from the planet's formation billions of years ago.
The bedrock that underlies the Antarctic continent was formed about 540 million years ago during the formation of the supercontinent Gondwana.
The Hadean Eon lasted from Earths formation about 4.5762 billion years ago until 4 billion years ago, some 576.2 million years.
Pangaea began to drift apart around 175 million years ago during the Mesozoic era. This breakup eventually led to the formation of the continents as we know them today.

Mainly because it happened so long ago - "erosion" wiped out essentially all the direct evidence long ago. Erosion includes things like plate tectonics and meteor strikes as well as wind and rain.
