What is the name of the hypothesis that states that the continents were once together but moved away from one another?
Continental drift
Continental drift was a theory that explained how continents shift position on Earth’s surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.
What hypothesis states that the continents were once joined to form a single supercontinent group of answer choices?
Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. He called his hypothesis continental drift.
What is a theory stating that the Earth’s surface is broken into many pieces?
Plate tectonics is the theory that Earth’s outer shell is divided into large slabs of solid rock, called “plates,” that glide over Earth’s mantle, the rocky inner layer above Earth’s core.
What do you think made the continents move?
Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.
Does the theory of the plate tectonics explain where volcanoes are located and why they are located in those places?
The theory of plate tectonics explains most of the features of Earth’s surface. It explains why earthquakes, volcanoes and mountain ranges are where they are. It explains where to find some mineral resources. Plate tectonics is the key that unlocks many of the mysteries of our amazing planet.

The theory of continental drift
What was the name of the supercontinent that formed Continental Drift?
Pangaea was a supercontinent that formed roughly 200 to 250 million years ago, according to the U.S. Geological Survey (USGS) and was responsible for the fossil and rock clues that led Wegener to his theory. [ Have There Always Been Continents?] When Wegener proposed continental drift, many geologists were contractionists.
How are magnetic anomalies related to continental drift?
Alternating patterns of magnetic anomalies on the ocean floor indicated seafloor spreading, where new plate material is born. Magnetic minerals aligned in ancient rocks on continents also showed that the continents have shifted relative to one another.
How are the different types of hypotheses developed?
Typically based on aspects such as accepted theory, literature printed on the topic at hand, past research, and even accepted theory, researchers normally develop this type of hypothesis from research questions, and they use statistical methods to check its validity.
