The evidence for continental drift included the fit of the continents;
the distribution of ancient fossils, rocks, and mountain ranges
; and the locations of ancient climatic zones.
Which two pieces of fossil evidence support the idea of continental drift quizlet?
How does each fossil support the hypothesis of continental drift? Each fossil supports this idea because they were found on different continents. What three key evidence supports continental drift?
Fossil clues, plants, rock clues and climate clues were discovered on the
different continents.
What are 6 pieces of evidence that support continental drift?
- Fossils.
- Continents fit like Puzzle Pieces. Matching fossils preserved in rocks of the same age but found on different continents. Ex. …
- Matching Rocks. Puzzle – like fit of continental shelves. Ex. …
- Mountain Ranges.
- Glacier Striations.
- Coal Beds.
Which of the following supports the continental drift theory?
Wegener
used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. … Wegener suggested that these creatures were alive in warm climate zones and that the fossils and coal later had drifted to new locations on the continents.
Which land feature supports the theory of continental drift?
Canyon
supports the theory of continental drift.
Which statement accurately describes plate tectonics?
Answer:The statement that accurately describes the aspects of plate tectonics that involve sub-duction and seafloor spreading is :
Crust is created at the coastlines of continents.
Which is one piece of evidence of seafloor spreading?
There is lots of evidence that proves that seafloor spreading is occurring. One piece of evidence is
mid-ocean ridges
. Rocks found near mid-ocean ridges are young and get older as the distance from the ocean ridge increases.
What are 5 pieces of evidence that support continental drift?
The evidence for continental drift included
the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones
.
What are two pieces of evidence for seafloor spreading?
Several types of evidence from the oceans supported Hess’s theory of sea-floor spreading-
evidence from molten material, magnetic stripes, and drilling samples
. This evidence also led sci- entists to look again at Wegener’s theory of continental drift.
What is continental drift theory explain?
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 are 4 pieces of evidence for continental drift?
The four pieces of evidence for the continental drift include
continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones’ locations
.
Why was the continental drift theory rejected?
This idea was quickly rejected by the scientific community primarily because
the actual forces generated by the rotation of the earth were calculated to be insufficient to move continents
.
What are the two main factors of tectonic plates movement?
Heat and gravity
are fundamental to the process
The energy source for plate tectonics is Earth’s internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces. It was once thought that mantle convection could drive plate motions.
Why is the continental drift theory important?
continental drift, large-scale horizontal movements of continents relative to one another and to the ocean basins during one or more episodes of geologic time. This concept was
an important precursor to the development of the theory of plate tectonics
, which incorporates it.
What is the meaning of Pangea?
Pangea’s existence was first proposed in 1912 by German meteorologist Alfred Wegener as a part of his theory of continental drift. Its name is derived from the Greek pangaia, meaning
“all the Earth.”
What is the theory of plate tectonics?
The theory of plate tectonics states that
the Earth’s solid outer crust, the lithosphere, is separated into plates that move over
the asthenosphere, the molten upper portion of the mantle. … Thus, at divergent boundaries, oceanic crust is created.
