For the most part, all of the continents are equal in age and were split from larger continents millions of years ago through plate tectonics which keeps surface area moving under and over plates.

All the continents were joined together in one super continent called?
The oldest of the super continents was called Rodinia
Why is Australia the oldest continent?
Because of the lack of tectonic activity, compared to the rest of the continents. Which means features from early parts of Earths history have managed to survive, and have not been destroyed in late-Tertiary and Quaternary uplift and extensive glacial erosion that the other continents went through.
How many continents are there in there?
Well, originally there are 5 continents. However, counting Oceania and Antarctica make it 7 continents.
What moves continents?
Continents are basically floating.
Which continents have mountains?
There are mountains on all continents.

true

What does it mean when you say that australia is the oldest of the continents?
That it is upon this Continent that the oldest fossils or other geological specimens are found.
Is the age of the sea floor the same age of the continents?
No. The sea floor is much younger than the continents. The oldest sea floor is about 200 million years old. The continents are billions of years old.
Is Europe the oldest continent?
No, because all of the continents that exist, where formed the very same time.
How would the age of the oldest rocks on the continents compare with the age of the oldest rocks on the seafloor if the rock on the continents is continually formed but not removed?
The oldest rocks on the continents would be much older than the rocks on the sea floor because the rocks on the continents are not being removed unlike the rocks on the sea floor that are made by the mid-ocean ridge are being removed by deep ocean trenches. this prossess that is occuring on the sea floor is called sea floor spreading. evidence of this is the Pacific ocean shrinking and the Atlantic ocean growing.
What is the oldest state capital in the US nation?

Which is the oldest continent on the globe?

Why are the oldest parts of the earth's crust found on continents?
The older peices of the Earths crust are significantly lighter than the newer peices, (i.e. oceanic plates / basalt) forcing them to the surface.
What is older the continents or the ocean floor?
On average, continents are older than ocean basins. Due to the action of plate tectonics, ocean crust is being formed and destroyed continuously. The oldest oceanic crust is about 200 million years old, whereas continents, which are less dense than oceanic crust and tend not to be subducted into the mantle, can be more than 3,000 million years old in places.
Why is Australia the oldest continent?
Because of the lack of tectonic activity, compared to the rest of the continents. Which means features from early parts of Earths history have managed to survive, and have not been destroyed in late-Tertiary and Quaternary uplift and extensive glacial erosion that the other continents went through.
