Evidence of continental drift includes matching Coastlines, geological similarities between continents, and the distribution of fossils and ancient species across continents that are now separated. Additionally, the discovery of mid-ocean ridges and the theory of plate tectonics further support this idea.

What evidence does the continental drift have that the continents were once connected?
Evidence for continental drift includes the fit of continents like South America and Africa, similar rock formations and mountain ranges on different continents, and the distribution of fossils that were once found on now widely separated landmasses. These pieces of evidence suggest that the continents were once connected in a single landmass called Pangaea.
What connected all the continents.?
The supercontinent Pangaea connected all the continents about 300 million years ago. Over time, Pangaea split apart, leading to the formation of the continents as we know them today.
Why did Wegener believe that all continents had once been joined?
Wegener believed all continents had once been joined because of the similar shapes of coastlines, matching geological formations across continents, and evidence of past glaciation extending from multiple continents, suggesting they were once connected.
Why did early mapmakers think the continents were once connected?
Early mapmakers thought the continents were once connected because they observed similarities in coastlines, geological formations, and fossil records across different continents. Additionally, the concept of continental drift and the theory of plate tectonics have since provided scientific explanations for the movement of continents over time.
What is 1 way you know that all the continents were connected at one point?
One way we know that all the continents were connected at one point is through evidence of similar rock formations, fossils, and mountain ranges across different continents, indicating they were once part of a single landmass known as Pangaea.
Theory that continents were once connected?
The theory is called continental drift, proposed by Alfred Wegener. It suggests that continents were once part of a supercontinent called Pangaea and have since drifted to their current positions. This theory is supported by evidence such as matching coastlines and similar geological features on different continents.
What was the first evidence that led people to think that the continents were once connected?
The first evidence that led people to think that the continents were once connected because of earthquakes
If the continents were once connected what might be similar about the coastlines where they were connected?
If the continents were once connected, similarities in coastline features could include similar shapes, geological structures, and fossil evidence of past connections. Additionally, the coastlines might have similar trends or patterns that suggest common tectonic history.
Who believed the continents were once connected but drifted apart?
Alfred wegener
How do you know that the continent of today were once connected?
I SAW IT in a book about the past all the continents were all hooked together but something broke it apart.
How do scientists know about continents once existing of landmasses?
There are two main evidences for this: 1. The continents fit together like a puzzle 2. There are both extant and extinct animal and plant species present on several continents that are not connected
What is the therory of Pangaea?
The theory is is that once all the continents were connected as 1 super continent. Later they split up to create the 7 we know now.
What evidence is there that the present-day Continent were once a single landmass?
One piece of evidence that indicates the continents were once connected is the shape of the continents. Many of the continents look as if they fit together like a puzzle.
What 2 continents do historians believe were once connected by a land bridge?
its is north America
Why did wegener think the continents moved?
Wegener proposed the theory of continental drift because he noticed how coastlines of continents seemed to fit together like pieces of a puzzle. He also observed similarities in rock formations, fossils, and climate across continents that suggested they were once connected. These observations led him to suggest that the continents had moved over time.
What is the Wagners theory?
Wegener's theory was that all continents were once connected and are slowly drifting around.
All continents were once connected as one large landmass are now called?
Pangaea.
