Why are no rocks found that date from the first 800 million years of Earth's-existence?
Earth was too hot to have solid rocks at that time.

Why are rocks found that from the first 800 million years of earth existence?
Earth was too hot to have solid rocks at that time.
Why are no rocks found that data from the first 800 million years of Earth's existence?
The lack of rocks from the first 800 million years is primarily due to geological processes like erosion, subduction, and intense volcanic activity that have altered or destroyed the original rocks. The Earth's early crust was also likely more unstable and subject to repeated melting and reformation, further contributing to the lack of preserved rocks.
What is the age of the rocks found in tug hill plateau?
542 million years ago
How old are the oldest rocks found on the sea floor?
Around 200 million years of age.
What is the approximate age of the Atlantic Ocean seafloor rocks in million of years?
The seafloor rocks of the Atlantic Ocean are generally around 200 million years old, with the youngest rocks found near the mid-Atlantic ridge, formed by seafloor spreading. As you move away from the ridge, the age of the rocks increases, with some older sections dating back to the Jurassic period. The oldest seafloor rocks are typically found near the continental margins, where they can be over 200 million years old.
In rock layers what is usually found at the bottom?
In rock layers, the oldest rocks are typically found at the bottom. This is due to the principle of superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are deposited first and are at the bottom, while the youngest rocks are at the top.
Why are no rocks found that date from the first 800 million years of earths existence?
Rocks from the first 800 million years of Earth's existence likely have not survived due to intense geological activity such as volcanic activity, tectonic plate movements, and weathering processes. The Earth's crust during this time was likely unstable and constantly being recycled, making preservation of rocks difficult. Additionally, any rocks that did form may have been subsequently altered or destroyed by subsequent geological processes.
Who discovered the Feldspar Rocks?
The person who first found feldspar rocks is unknown, however, these types of rocks are commonly found in the Earth's crust and along road cuts of Ontario. Feldspar is commonly found in granite.
The oldest fossil of dinosaurs occur in rocks that are approximstely how many million years old?
The oldest dinosaur fossils date from the Carnian stage of the Triassic period. That was around 220 million years ago. The first dinosaurs were small carnivores, like Eoraptor, and small, long necked herbivores called prosauropods.

Why are there no samples of rocks from the early Precambrian era?
Rocks from the early Precambrian era have likely been destroyed due to the constant geological processes such as heat, pressure, and erosion over billions of years. The Earth's surface has undergone significant changes since that time, making it rare for such ancient rocks to be preserved and accessible for study.
