Geological evidence has shown that the movement of tectonic plates, which make up the Earth's crust, is responsible for the continents moving apart. This movement is driven by the process of seafloor spreading, where new oceanic crust is formed along mid-ocean ridges, pushing the continents farther apart over time. This evidence is supported by studies of magnetic anomalies in seafloor rocks and the distribution of fossils and rock formations across different continents.
What else can I help you with?
What convinced scientists that the the continents were slowly moving?
Scientists were convinced that continents were slowly moving due to evidence such as fit of the continents' coastlines, matching geological features across continents, and the discovery of mid-ocean ridges and seafloor spreading. This evidence supported the theory of plate tectonics, which explains how continents move over time.
What evidence do we have for continental drift?
Evidence for continental drift includes the matching shapes of coastlines across different continents, similarities in rock formations and geological features between continents, and the distribution of fossils of the same species on different continents that were once connected. Additionally, the alignment of mountain ranges and earthquake patterns also support the theory of continental drift.
Pieces of evidence does NOT support the continental drift theory?
the continents fit together like a puzzle
How sea-floor spreading provides a way for continents to move Explain?
Sea-floor spreading is the process where new oceanic crust is formed at mid-ocean ridges, pushing the existing crust apart. As the crust spreads, it carries the continents on tectonic plates with it, causing the continents to move. This movement is called plate tectonics, and it is responsible for the shifting of continents over geological time scales.
What theory that continents move apart form each other?
The action of continents drifting apart from each other is called, "Continental Drift". It is no longer a theory, as it has been proven to be so. Of course, as certain continents move apart from each other, they also are moving closer to other continents.
What made Alfred wegener think the continents move?
Alfred Wegener proposed the theory of continental drift in the early 20th century because he observed similar plant and animal fossils on continents that are now far apart, as well as matching geological formations and evidence of ancient climates that suggest the continents were once joined together and have since drifted apart.
How were the fossils symbols and mountains belts helpful in deciding where to move the continents?
Fossils found on different continents suggested that they were once connected due to similar species being found far apart. Mountain belts on different continents lined up when the continents were pieced together, indicating a shared geological history. These pieces of evidence helped in understanding continental drift and the movement of continents over time.
How were mountain belts helpful in deciding where to move the continents?
You can not DECIDE where to move continents, the movement of continents is a natural geological process, nothing man does can affect it.
What information did Wegner need to strengthen his argument?
Wegner needed evidence of a mechanism by which continents could move, data supporting the idea of past and present continental positions, geological similarities between continents, and paleoclimatic evidence to strengthen his argument for continental drift.

How were the fossil symbols helpful in deciding where to move the continents?
Fossil symbols were helpful in deciding where to move the continents because they provided evidence of past connections between landmasses. Similar fossils found on continents that are now far apart suggest that they were once joined together. By using fossil evidence, scientists could determine the past positions of continents and reconstruct ancient supercontinents like Pangaea.
How have continents moved in the past?
Plate tectonics. Continents are the exposed (from the oceans) geological areas of tectonic plates. Continents can also be on top of more than one tectonic plate. When these plates move, continents move with them. Millions of years ago, continents were split apart and also created by tectonic plate movement.
What evidence do we have for continental drift?
Evidence for continental drift includes the matching shapes of coastlines across different continents, similarities in rock formations and geological features between continents, and the distribution of fossils of the same species on different continents that were once connected.

How can magma cause the plates that carry the continents to move apart?
magma is very hot so as it boils it moves the plates of the earth causing the continents to slowly move apart
