What theory explained how earth was once a single?
The theory that explains how Earth was once a single supercontinent is called the "Theory of Plate Tectonics." This theory suggests that Earth's outer shell is divided into several plates that move and interact with one another over time, causing continents to drift apart or come together. The supercontinent that is believed to have existed in the past is known as Pangaea.
What proposed explanations overcame the problem of how continents moved?
The theory of plate tectonics provided a comprehensive explanation for how continents moved. This theory suggests that the Earth's rigid outer shell, called lithosphere, is divided into plates that float and move on the semi-fluid asthenosphere below. The movement of these plates drives the shifting of continents over time.
Which of the three types of plate movement provided some evidence and supported Wegener's theory?
The movement of plates at divergent boundaries, where new crust is created as plates pull apart, supported Wegener's theory of continental drift. This movement of plates helped explain how continents could have once been connected and then drifted apart over time.
How do plates pull apart?
The process called plate tectonics is responsible for plates pulling apart. Over time, and with the combination of carbon dioxide, erosion, and force, plates are able to pull apart. This will eventually cause some plates to separate from one another.
Wegner's theory of continental drift?
His theory is that all the continents were connected and made a super continent called Pangaea then eventually the moving of tectonic plates over the millions of years caused the continents moves apart.
What is theory called that explains how the continents moved apart?
The theory that explains how the continents have moved apart is called plate tectonics. This theory suggests that the Earth's outer shell is divided into several plates that move and interact with each other, causing continents to drift over long periods of time. This movement is driven by processes such as seafloor spreading and subduction.
What is the theory that continents can drift apart from one another?
The theory is called continental drift, which suggests that Earth's continents were once connected as a single landmass called Pangaea and have since moved apart over millions of years due to plate tectonics. This process is driven by the movement of the Earth's tectonic plates, resulting in the shifting and separation of continents.
What is the theory that continents have moved slowly over time to their current locations?
The theory that continents have moved slowly over time to their current locations is called continental drift. This theory was proposed by Alfred Wegener in the early 20th century and later developed into the theory of plate tectonics, which explains the movement of Earth's lithosphere through the interaction of tectonic plates.

What is the theory in which scientists believe that the continents have moved over time?
The theory that scientists believe explains how the continents have moved over time is called plate tectonics. This theory suggests that the Earth's outer shell, or lithosphere, is divided into large plates that float on the semi-fluid asthenosphere beneath. The motion of these plates is responsible for various geological phenomena such as earthquakes, volcanic activity, and the shifting of continents.
How did Wegener explain the way the continents moved?
Wegener proposed the theory of continental drift, suggesting that the continents were once connected in a single landmass called Pangaea. He proposed that the continents drifted apart over time due to the movement of the Earth's crustal plates.
What is a theory proposing the continents slowly moved into their current locations called?
The theory proposing that continents slowly moved into their current locations is called "plate tectonics." This theory suggests that Earth's outer shell is divided into several plates that glide over the mantle, causing the continents to shift over time.

What did Alfred Wegender mean by ''continental drift''?
Alfred Wegener proposed the theory of continental drift, suggesting that continents were once joined together in a supercontinent called Pangaea and have since moved apart. He argued that the continents drift slowly over time due to the movement of Earth's tectonic plates. This theory laid the groundwork for the development of the modern theory of plate tectonics.
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.
How did the continents move apart?
The theory of plate tectonics suggests that the movement of the continents is driven by the gradual movement of huge plates of Earth's crust, which float on the semi-fluid mantle beneath them. These plates constantly drift and collide, leading to the separation and movement of continents over millions of years through processes like seafloor spreading and subduction.
Which of the three types of plate movement provided some evidence and supported Wegener's theory?
The movement of plates at divergent boundaries, where new crust is created as plates pull apart, supported Wegener's theory of continental drift. This movement of plates helped explain how continents could have once been connected and then drifted apart over time.
