What is the main reason why the age of oldest rocks can vary from one part of a continent to another?
Many lands were underwater when others were rising from the sea. Islands and lands begin underwater and some lands are more recent. For example, the coast of Australia's rocks are younger than the rocks in the centre of Australia.
all continets used to be conected called Pangaea so on the edge of one continet there may be something of the same on the opposite or parallel continet look at a picture of south America and i think Asia or Russia and there will be a tiny space where it seems they used to be conected

Are the oldest rocks on Earth in the Grand Canyon?
No, the oldest rocks on Earth are not located in the Grand Canyon. The oldest rocks found on Earth are estimated to be over 4 billion years old and are typically found in locations such as Canada, Australia, and Africa.
What part of the sedimentary of rock is the oldest?
Protolith is a term used to describe the parent rock of a metamorphic rock. Conglomerate is a sedimentary rock that can be composed of clasts of sedimentary, igneous, or metamorphic rocks, or any number of combinations of all.
What is the oldest rocks Florida and acutes match Africa?

Why are the oldest rocks found in Iceland?
The oldest rocks in Iceland are found because of its location over the Mid-Atlantic Ridge, where new oceanic crust is continually formed. As a result, the rocks at Iceland's boundary represent some of the oldest on Earth as they have not been subjected to the intense tectonic activity and recycling that typically occurs at plate boundaries.
The oldest rocks are located at mid-ocean ridges?
Nope. The oldest rocks are located on continents, usually away from the ocean. The mid-ocean ridges are, in fact, home of some of the youngest rocks. The reason for this is what is called sea-floor spreading. Mid-ocean ridges form at places where oceanic plates diverge, or move apart. As this happens, magma rises from within the Earth to fill the gap. The magma cools and solidifies, creating new seafloor. This process continues as the plates continue to spread apart.
What is oldest and most stable part of a continent?
The oldest and most stable part of a continent is a craton, found in tectonic plates in the Earth's lithosphere. Cratons are made up of crystalline basement rocks, have a thick crust and are deeply rooted in the Earth's mantle.
What is the oldest and most stable part of the continent?
The oldest and most stable part of a continent is a craton, found in tectonic plates in the Earth's lithosphere. Cratons are made up of crystalline basement rocks, have a thick crust and are deeply rooted in the Earth's mantle.
What is the most oldest and most stable part of a continent?
The oldest and most stable part of a continent is a craton, found in tectonic plates in the Earth's lithosphere. Cratons are made up of crystalline basement rocks, have a thick crust and are deeply rooted in the Earth's mantle.
How do the ages of the oldest sediments compare to the ages of the oldest continental rocks?
The oldest sediments are generally younger than the oldest continental rocks. Sediments are continuously being deposited on the Earth's surface, while continental rocks have undergone processes of solidification and deformation over billions of years. This means that the oldest continental rocks are usually much older than the oldest sediments.
Are the oldest rocks on land or in the ocean?
The oldest rocks are typically found on land, as they have not been eroded away by oceanic processes. The oldest known rocks on Earth are found in Western Australia and are estimated to be around 4 billion years old.
What happens to the oldest rocks on the ocean floor to continue the rock cycle?
Or they get subducted and re-enter the mantle or they get obducted onto continent (the latter being called an ophiolite).
When looking at rocks where do you generally find the oldest rocks?
in india
What is the most stable part of a continent?
The oldest and most stable part of a continent is usually the craton, which is a large area of exposed ancient rocks that have not undergone significant tectonic activity for millions of years. Cratons are found in the interior regions of continents and provide a stable foundation for the continent's geology.
What are the rocks of North America?
The rocks of North America are those rocks from which the continent is formed.
Where are the oldest rocks in the ocean crust?
The oldest rocks are actually on land but in the ocean crust they would be the rocks closest to land. The mid-ocean ridge forms new rocks. They are usually located in the middle of the ocean.
When on a geologic column the oldest rocks are located where?
The oldest are located at the bottom of an undisturbed column.
What is the oldest suburb in Australia?
Australia's oldest suburb is found in Sydney. It is the suburb of The Rocks.
