What helped prove 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 did not provide evidence for continental drift?
Which of these did NOT provide evidence for continental drift? oceanic plate theory.
Which of the following best describes the development of the theory of plate tectonics?
Which of the following best describes the development of the theory of plate tectonics? Scientists used the discovery of seafloor spreading to support continental drift, which led to the theory of plate tectonics.
How can fossils be used as evidence for continental drift?
Fossil Evidence One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined.
What are 5 pieces of evidence that support 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.
What are the 4 evidence of continental drift?
What are the 5 evidences of continental drift?
They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.
Which of the following describes continental drift?
Continental drift is the hypothesis that the Earth’s continents have moved over geologic time relative to each other, thus appearing to have “drifted” across the ocean bed.
Which of the following best explains the hypothesis of continental drift?
Which statement best explains Wegener’s hypothesis of continental drift? Volcanic activity slowly reshapes the continents throughout Earth’s geologic history. The continents shift locations as a result of major catastrophes like meteorite impacts and earthquakes.
What evidence have you discovered to explain how similar fossils could be found on continents that are now separated by vast oceans?
Also, fossils of the plant Glossopteris have been found on South America, Africa, India, Antarctica, and Australia. The only way these fossils can be found on continents that are separated by oceans is if the continents were once together (connected). These ancient animals and plants could not have swam across oceans!
Which of the following provides evidence of plate motion?
Modern continents hold clues to their distant past. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed.
What are the 3 types of continental drift?
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries.
Why must a gastric lavage be sent to the laboratory promptly?
A gastric lavage must be sent to the laboratory promptly because it must be processed as soon as possible or neutralized with 10% sodium carbonate to avoid loss of mycobacteria due to gastric acidity.
How is gastric lavage performed in the conscious animal?
In the conscious animal, gastric lavage is performed after induction of general anesthesia with the patient intubated to prevent aspiration. The cuff of the endotracheal tube should be assessed before initiation of gastric lavage to ensure a snug fit.
What are the contraindications of gastric lavage?
Absolute contraindications of gastric lavage include: the use of saline or intravenous infusion fluids as lavaging fluid may lead to hypernatremia Gastric lavage should not be used routinely, if at all, in poisoning cases.
How is the location of the gastric lavage tube verified?
Whenever gastric lavage is performed, a large-bore (36 or 40 French tube in adults) should be placed through the mouth, and proper location of the tube in the stomach should be verified clinically or radiographically. Position paper: Gastric lavage. J Toxicol Clin Toxicol 42:933–943, 2004.
