Arthur Holmes proposed the theory of continental drift in the early 20th century. He suggested that the continents were once joined together in a supercontinent called "Pangaea" and have since drifted apart due to the movement of the Earth's tectonic plates. Holmes' hypothesis laid the groundwork for the modern theory of plate tectonics.

Which theory explains how the continents drifted from one landless to their present locations?
The theory that explains how the continents drifted from one landmass to their present locations is called plate tectonics. It suggests that the Earth's outer shell is divided into several plates that move and interact with each other, leading to the drifting of continents over time. This movement is driven by processes like seafloor spreading and subduction.
What are the arguments against the wegener continents theory?
Some arguments against Alfred Wegener's theory of continental drift include lack of a plausible mechanism to explain how continents could move, insufficient evidence to support the idea of continents drifting over time, and skepticism from the scientific community at the time due to the lack of detailed data and research. Additionally, Wegener's theory faced opposition because it challenged the widely accepted theory of fixed continents.
Who came up with the theory of Pangaea?
The theory of Pangaea was proposed by Alfred Wegener in 1912. He suggested that the continents were once joined together before breaking apart and drifting to their current positions.
What is the term for the separation of the continents?
The term for the separation of the continents is "continental drift." This theory, proposed by Alfred Wegener in the early 20th century, suggests that the Earth's continents were once joined as a single landmass called Pangaea before drifting apart over millions of years.
What its the theory that the continents we're once joined and slowly drifted apart?
The theory is called plate tectonics, which posits that Earth's outer shell is divided into several large, rigid plates that move and interact with one another. This movement can result in phenomena such as earthquakes, volcanic activity, and the drifting of continents over millions of years.
What was Arthur Holmes' theory?
Arthur Holmes theory was that the mantle under goes thermal convection.
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.
What is the Wagners theory?
Wegener's theory was that all continents were once connected and are slowly drifting around.
Who modernly states the theory of Pangaea?
Arthur Holmes i believe.
What evidence did Arthur Holmes have to support his theory?
he didn't have anything to prove
When was Arthur Holmes' theory proved?
Arthur Holmes' theory of plate tectonics was not proven by a single event or discovery. Instead, it was gradually accepted as more evidence from seafloor spreading, magnetic anomalies, earthquakes, and volcanic activity supported the theory. Holmes' work laid the foundation for the development of the modern theory of plate tectonics.
Whose idea later assisted in the recognition of wegener's theory?
Arthur Holmes's idea of mantle convection helped provide a mechanism for plate tectonics, which later supported the recognition of Wegener's theory of continental drift. Holmes's work contributed to advancing the understanding of Earth's geology and the movement of continents.
What theory that continents move apart form each other?
The theory that explains how continents move apart from each other is called plate tectonics. This theory states that the Earth's lithosphere is divided into several large plates that float on the semi-fluid asthenosphere underneath, causing the plates to interact and move over time. As the plates move, they can separate from each other, leading to the drifting of continents apart.
Is it the fact that the continents are drifting away with constant speed?
Continental drift is a theory that describes the movement of Earth's continents over time. The continents are not drifting away at a constant speed but are moving slowly due to the shifting of tectonic plates. This movement is around 2-5 centimeters per year, which is relatively slow on a human timescale.
Which theory explains how the continents drifted from one landless to their present locations?
The theory that explains how the continents drifted from one landmass to their present locations is called plate tectonics. It suggests that the Earth's outer shell is divided into several plates that move and interact with each other, leading to the drifting of continents over time. This movement is driven by processes like seafloor spreading and subduction.
What is the theory of pangae?
The theory of Pangaea is the theory that the Earth was once covered by one giant continent or land mass. The land mass supposedly started to break apart when the dinosaurs went extinct. The theory explains why different continents look like they are part of a jigsaw puzzle, and how the same type of fossil was found on to different continents. The theory also explains why our continents today are slowly drifting apart.
Whose ideas later assisted in the recognition if Wegener's theory?
Arthur Holmes's ideas in the 1920s about mantle convection and radioactive heating helped support Alfred Wegener's theory of continental drift by providing a mechanism for how the continents could move. This helped pave the way for the eventual acceptance of Wegener's ideas as the theory of plate tectonics.
