How Old is the Earth So far, rocks older than 3.0 billion years have been found in North America, India, Russia, Greenland, Australia, and Africa. The oldest rocks in North America, found in Minnesota, give a U-Pb discordia age of 3.56 billion years (Figure 5). The oldest rocks yet found on the Earth are in Greenland, South Africa, and India. The Greenland samples have been especially well studied.

Dating Fossils in the Rocks Background Info. This diagram shows a selection of rock layers, or stratigraphic columns, from the Koobi Fora geologic formation on the eastern shore of Lake Turkana in Kenya. This area is a ridge of sedimentary rock where researchers have found more than 10,000 fossils, both human and other hominins, since 1968.

Deep sea The deep sea floor represents the largest habitat on earth. It ranges from the edge of the continental shelf at 200m to the bottom of the ocean. At the edge of the continental shelf is the shelf break, where the gradient of the floor increases down the continental slope.

9 More of the Oldest Objects Ever Found 1Zircon Crystal (4.4 Billion Years Old) This ancient zircon crystal is the oldest known material formed on Earth. Scientists have dated the crystal to about 4.4 billion years, making it the earliest confirmed piece of the planet's crust. The crystal was found in an arid region north of Perth, Australia, in a low range of hills called the Jack Hills, in 2001.

Manganese Nodule Discovery Points to Genesis Flood Scientists recently discovered a large batch of manganese nodules on the floor of the Atlantic Ocean. 1 These metallic pellets provide strong evidence that most seafloor sediments were deposited rapidly, not slowly and gradually over millions of years.

What Is the Main Type of Rock in the Oceanic Crust? It is a dense, dark-colored rock that has small crystals, many too tiny to see. It is rich in magnesium and iron. The oceanic crust, largely made up of basalt is located under the ocean floor. Measuring about 4 miles thick, it is thinner but heavier than its counterpart, the continental crust.

The Age of the Earth The oldest rocks which have been found so far (on the Earth) date to about 3.8 to 3.9 billion years ago (by several radiometric dating methods). Some of these rocks are sedimentary, and include minerals which are themselves as old as 4.1 to 4.2 billion years.

'Oldest signs of life on Earth found' Scientists discover potentially oldest signs of life on Earth – 3.5 billion-year-old microbe traces in rocks in Australia. Evidence of the complex microbial ecosystem was found in sedimentary rocks in the remote Pilbara region in Western Australia Photo: Alamy. By Jonathan Pearlman, Sydney. 9:13AM GMT 13 Nov 2013. Comments. Scientists have discovered possibly the earliest signs of life on Earth – remains of bacteria that are almost three-and-a-half billion years old – in a remote region of north-west Australia.

How would the age of the oldest rocks on the continents compare with the age of oldest rocks on the seafloor? Report Abuse. The oldest rocks on the continents are much older than those on the sea floor. The oldest rocks on the continents are between 3.5-4.0 billion years old. Rocks of this age have been found in the centre of ancient continents-the Canadian Shield, Australia and Africa.he oldest rocks on continental crusts are generally in the center of the continent, while the oldest rocks of ocean crust are generally farthest away from the ocean-ridges.

OCEAN FLOOR Just a century ago, the ocean floor was largely unknown. Now we know that the deep oceans have features such as mountains, deep valleys, and vast plains. Many of these are formed by the movement of the tectonic plates that make up Earth’s crust. Far below the ocean’s surface, volcanic mountain chains are rising in mid-ocean zones where plates pull apart. Elsewhere, deep trenches descend in subduction zones where plates collide and one dives below the other. Oceanographers use sonar to map the ocean floor. The research ship directs sound waves at the bottom, and charts the echoes that bounce back to create a detailed map.

- • In Wegener's time, people wondered how the continents could move through solid rock. • New evidence in the 1950’s supported Wegener's proposal. • Scientists mapping the floor of the Atlantic Ocean found an underwater mountain chain in the middle of the Atlantic. PLATE TECTONICS

High School Earth Science/Relative Ages of Rocks A series of sedimentary beds is deposited on an ocean floor. The sediments harden into sedimentary rock. The sedimentary rocks are uplifted and tilted, exposing them above the ocean surface. The tilted beds are eroded by rain, ice, and wind to form an irregular surface. A sea covers the eroded sedimentary rock layers.

Oldest Known Rocks On Earth Discovered: 4.28 Billion Years Old These rocks, known as faux-amphibolites, may be remnants of a portion of Earth's primordial crust -- the first crust that formed at the surface of our planet. The discovery of rocks as old as 4.28 billion years pushes back the age of the most ancient remnant of Earth's crust by 300 million years. Researchers have discovered the oldest rocks on Earth -- a discovery which sheds more light on our planet's mysterious beginnings.

Where Are the Oldest Rocks on Earth Found? The oldest geological material ever found, which are not technically rocks, are mineral grains called zircons found in Western Australia, which date back about 4.36 billion years. Technically, the oldest known rocks existing on Earth are not from Earth at all, but are instead of extraterrestrial origin.he oldest rocks in the grand canyon are about 2 billion years old, but they are not even half the age of the oldest known rocks on earth.
