The theory that suggests continents move across the Earth's surface is called plate tectonics. This theory explains how the Earth's outer shell is divided into large, rigid plates that move and interact with each other, causing phenomena like earthquakes, volcanic activity, and the formation of mountains.
What else can I help you with?
Idea that continents move slowly across earth's surface is called what?
The idea that continents move slowly across Earth's surface is called plate tectonics. This theory explains how the Earth's lithosphere is divided into plates that move and interact with each other, leading to processes such as earthquakes, volcanic activity, and the formation of mountain ranges.
Wegener's theory that the continents slowly moved over earths surface became known as?
Wegener's theory that the continents slowly moved over Earth's surface became known as the theory of continental drift.
What are four pieces of evidence used by Alfred Wagner to support his theory of continental drift?
Fossil similarities across continents. Matching geological formations across continents. Alignment of mountain ranges across continents. Distribution of ancient climates and glacial deposits.
What 3 factors did wegener use to support his theory of drifting continents?
Wegener used evidence from the fit of the continents, the distribution of fossils, and similarities in rock formations and mountain ranges across different continents to support his theory of drifting continents.
Why is ''cotinental drift'' an appropriate title for wegeners theory?
"Continental drift" is an appropriate title for Wegener's theory because it describes the movement of continents over long periods of time, drifting across the Earth's surface. The theory suggests that continents were once joined as a single landmass, called Pangaea, and have since drifted apart to their current positions.
What is the hypothisis that the continents slowly move across earth's surface?
The theory of plate tectonics.

The theory of how earth's continents move over its surface its known as?
Plate tectonics.

What is the fixed continent theory?
The fixed continent theory is an outdated idea that suggested continents were stationary and fixed in one location on the Earth's surface. It was replaced by the theory of plate tectonics, which explains that continents move due to the shifting of tectonic plates in the Earth's crust.
What information did Wegener not have?
Alfred Wegener did not have a mechanism to explain how continents could move across the Earth's surface. He proposed the theory of continental drift in the early 20th century, but it wasn't until the development of plate tectonics in the 1960s that a satisfactory explanation for the movement of continents was provided.
How did the continents get their current positions?
The movement of tectonic plates over millions of years is responsible for the current positions of continents. Plate tectonics, a theory that explains how Earth's outer shell is divided into several plates that move across the Earth's surface, has caused continents to drift and collide, leading to the formation of the current landmass configurations.
Do some scientists think the continents once formed a single landmass?
Yes, the theory of continental drift suggests that the Earth's continents were once joined together in a single landmass called Pangaea. This theory is supported by evidence such as the matching shapes of continents, distribution of fossils, and geological similarities across continents.
What does the theory of plate tectonics and continental drift say about the positions of the continents?
The theory of plate tectonics states that the Earth's outer shell is divided into several large plates that move and interact with each other. Continental drift is the idea that continents move across the Earth's surface over time. Both theories suggest that the positions of the continents have changed and continue to change due to the movement of these tectonic plates.
