Four million years ago, during the late Miocene epoch, the Earth's geology was characterized by significant tectonic activity, leading to the formation of mountain ranges and changes in sediment deposition. Rocks from this period include sedimentary formations created from ancient river systems and coastal environments, as well as volcanic rocks from eruptive events. The climate was generally warmer than today, influencing erosion processes and the types of minerals present. Fossils found in these rocks often reflect the diverse ecosystems that existed at the time, including early ancestors of modern flora and fauna.
What else can I help you with?
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 does four million thirty look like?
Four million thirty looks like this: 4,000,030
What types of strata rocks and fossils would've been found in West Virginia 100 million years ago?
West Virginia 100 million years ago would have been part of a shallow seaway, so you would find marine sedimentary rocks like limestone, sandstone, and shale. Fossils of marine life such as ammonites, bivalves, brachiopods, and possibly marine reptiles like mosasaurs might be discovered in these rocks.
How do you carbon date rocks 10 million years old?
You cannot. Carbon dating is not useful for dating things more than about 50,000 years old. You would have to use a different radioisotope to date something 10 million years old. Potassium-Argon dating would work for some rocks.
What happens to sediments after a million years?
After a million years, sediments can undergo diagenesis, which includes compaction and cementation. This process transforms loose sediments into solid rocks like sandstone, shale, or limestone. Over time, these rocks may be uplifted and exposed at the Earth's surface by tectonic forces.
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.
How old are most sedimentary rocks?
Sedimentary rocks can vary in age from recent (formed within the last few years) to billions of years old. The age of sedimentary rocks depends on when the sediments were deposited and how long they have been exposed to processes like compaction and cementation to form rock.
How do you write four point three million?
like this ==> 4,300,000
How old is the Nile River?
As old as history itself, at least a few million years.
Where is the youngest rock found what is the age of the youngest rock?
The youngest rocks on Earth are typically found at mid-ocean ridges, where new oceanic crust is formed by volcanic activity. The age of these rocks can be as young as a few million years, with some areas of the mid-ocean ridges, like the East Pacific Rise, producing basaltic rock that is around 1-2 million years old. Additionally, volcanic islands and hotspots, such as those in Hawaii, also feature very young rocks, some just a few hundred thousand years old.
How do you write three million four?
Make it look like this ===> 3,000,004
