Basically, it's thought to be because of movements in the plastic mantle below the crust.
The hypothesis that states continents slowly moved to their present positions on Earth is known as the theory of plate tectonics. It suggests that Earth's lithosphere is divided into several large, rigid plates that move and interact with each other over time. These movements explain various geological phenomena, such as earthquakes, volcanoes, and mountain formation.
The hypothesis that states that continents slowly moved to their present-day positions on Earth is called continental drift. This theory was proposed by Alfred Wegener in the early 20th century, suggesting that continents were once part of a single supercontinent called Pangaea and have since drifted apart.
The present continents are not permanent features on Earth. They are part of the constantly shifting tectonic plates that make up the Earth's crust. Over millions of years, continents have moved and changed positions due to the movement of these plates through processes like plate tectonics.
After Pangaea started breaking up, the continents drifted apart due to plate tectonics. Over millions of years, they moved to their current positions on the Earth's surface. This process created the continents and oceans as we see them today.
North America was most recently attached to other continents as part of the supercontinent Pangaea around 300 million years ago. The breakup of Pangaea began around 175 million years ago, leading to the gradual separation of the continents to their present-day positions.
Continental drift :)
The reason is because of glacial desposits. The other reason is because of ice bergs and continental drift.
There is no city present in all continents. Each continent has its own distinct cities.
Through the passage of time, the continents have gradually moved across the earth's surface into their present positions. This is called the continental drift.

Dogs are pets bread by Man and therefore dogs are present on all continents.
Continents and tectonic plates drifted to their present positions due to the process of plate tectonics. This movement is driven by the slow shifting of the Earth's lithosphere on the more fluid asthenosphere beneath it. The movement of these plates over millions of years has resulted in the present configuration of the continents and ocean basins.
It has taken around 200 million years for continents to get to their present positions due to the process of plate tectonics, where large pieces of the Earth's lithosphere move slowly over the underlying mantle. This movement results in the shifting of continents and the formation of various landforms on Earth.
There is no city that exists on every continent. Each continent has its own unique cities, and no city is globally present on all continents.
