Are the continents and oceans always been in the same positions they are today?
No, the positions of continents and oceans on Earth's surface have changed over millions of years due to the process of plate tectonics. Continents have drifted apart and collided to form new landmasses, changing the configuration of oceans. This movement is ongoing, with the positions continuing to shift gradually over time.
Have the continents alway been in the same place?
No, the continents have not always been in the same place. Due to the process of plate tectonics, the continents have moved over geologic time scales. This movement has resulted in the formation of supercontinents and the current configuration of continents.
How long ago did Pangaea split into continents?
The original super-continent of Pangaea broke up about 200 million years ago during the Paleozoic era forming the continents of Gondwanaland and Laurasia. Gondwanaland later fragmented into Antarctica, Africa, Australia, India and South America. Similarly, Laurasia broke up into Asia, Europe and North America. The current 7 continents have been more or less in their current positions for the past few million years.
Why does the earth have 7 continents?
The Earth's continents are a result of tectonic plate movements over millions of years, leading to the current configuration of seven main landmasses. These continents have been shaped by geological processes such as continental drift, volcanic activity, and erosion. The number of continents is a human-made concept based on how we divide and categorize the Earth's landmasses.
What are two continents?
The contry that has two continents is Russia. The two continents in Russia are Europe and Asia. By the way you could have googled "The seven continents of the world" in images it would have been much quicker.
Have the continents always been where they are located today?
It is commonly accepted that the continents have not always been in their current locations. They are thought to have all been part of a super continent known as Pangaea.
What do the glossopteris fossils tell us about early positions of the continents?
That they must have been joined up in the past because the same fossils could not exist on the continents given their current position.

Have the continents and the oceans always been in the positions they are in today?
No, the continents and the oceans have not always been in the positions they are in today. The Earth's tectonic plates slowly move over time through a process called plate tectonics. This movement has resulted in the continents shifting positions and the reshaping of the oceans over millions of years.

Two contradictory beliefs to continental drift?
The concept of fixed continents in a static Earth environment, suggesting that landmasses have always been in their current positions. The belief that geological features, such as mountain ranges and ocean basins, are shaped by localized processes rather than the movement of continents.

What are the opposing views to the Pangaea theory?
One opposing view to the Pangaea theory is the theory of a static Earth, which suggests that continents have always been in their current positions. Another opposing view is the Expanding Earth theory, proposing that the Earth's continents move apart due to the planet's expansion rather than shifting on tectonic plates.
Does the case of mesosaurus by itself the theory why or why not?
The case of Mesosaurus does support the theory of continental drift, particularly in the context of plate tectonics. This freshwater reptile's fossils were found in both South America and Africa, which are now separated by the Atlantic Ocean. The presence of such a species in these two distant locations suggests that the continents were once joined, allowing Mesosaurus to inhabit both regions. Thus, it provides evidence against the idea that these continents have always been in their current positions.
