Not much change has taken place over a hundred years, but huge changes have taken place over the many millions of years of the earth's existence.

In the last 100 years, the continents have not significantly changed in terms of their positions, but there have been gradual shifts due to plate tectonics. Ocean levels have risen due to climate change, leading to coastal erosion and changes in marine ecosystems. Human activities have also caused pollution and depletion of ocean resources.

What is the main reason continents look very different from 100 years ago?
The main reason continents look very different from 100 years ago is due to the process of plate tectonics, which causes the movement of Earth's continents over time. This movement can result in the reshaping of continents, the formation of mountain ranges, and the opening or closing of oceans.
Is there a possibility that the current location of a continent would be different 100 years from now?
Yes. Continents are constantly moving, though at very low speeds, just a few inches in a year. In 100 years a continent would have moved, but not by a very large amount.
How and why have the shapes of the continents changed over millions of years?
Continental drift, driven by plate tectonics, explains how continents have moved over millions of years. The Earth's lithosphere is divided into several large tectonic plates that float on the semi-fluid asthenosphere beneath them. These plates move due to forces generated by mantle convection. As plates collide, pull apart, or slide past each other, continents can change their positions, leading to the shapes we see today.
How far is palm springs from the ocean?
Palm Springs is approximately 100 miles east of the Pacific Ocean.
How many miles of coast line does Georgia have?
Georgia has about 100 miles of coastline along the Atlantic Ocean.
Which continents moved apart during the time period 100 - 200 million years ago?
Pangea began to drift apart about 200 million years ago. Pangea split into two smaller continents: Gondwana and Laurasia. These continents lasted from about 200 million years ago to 100 million years ago.
What will the earth look like in 50 100 million years time?
The passage of 50 - 100 million years is long enough for a substantial amount of continental drift to take place, which will not only change the distance between continents but also raise new mountain ranges where continents collide with eachother, as well as opening new oceanic rifts.

What is the name of the supercontinetal that existed about 200 million through 100 million years ago?
The supercontinent that existed several million years ago is called Pangea. It combined all of today's continents into one supercontinent, mostly in the Southern Hemisphere. It was surrounded by a super ocean, Panthalassa, and started to break up 175 million years ago.

How might earth's surface change if tectonic plates continue to move?
The earth's continents in the past were originally one huge continent known as pangea. However convection currents and the force of gravity caused this single giant continent to split into a series of separate tectonic plates which moved and split away from each other, ultimately resulting in the position of the continents we know today. If this continues (and there is no reason to think it won't) then the position of the continents will continue to shift, new oceans will form (this has already started in the East African rift which will over 100's of millions of years eventually form a new ocean) and continents will collide forming new mountain chains.
The Atlantic Ocean did not exist 250 millions ago during the Permian period?
During the Permian period 250 million years ago, all of the continents were massed together into one supercontinent, Pangaea. The Atlantic Ocean didn't form until Pangaea broke apart, with the Americas moving west and Africa and Europe moving east. That didn't begin until the late Jurassic, about 100 million years later.
Did cell phones change over the past 100 years?
Yes, but they haven't been around over 100 years yet
Are the present continents a permanent feature on your planet?
No, they are moving and changing. But they do that very slowly, so we don't see much change even if we live to be 100.
How small did the Atlantic Ocean start out?
The atlantic ocean started out to be a land 100 years ago but now it is water because of a great flood that sank it down
