Give two pieces of evidence for seafloor spreading?
Paleomagnetic stripes on either side of mid-ocean ridges demonstrate the symmetric pattern of magnetic reversals found in oceanic crust, supporting the idea of seafloor spreading. Age dating of oceanic crust samples reveals that the further away from mid-ocean ridges, the older the crust gets, providing direct evidence for the continuous creation of new seafloor at spreading centers.
Is plate tectonics the main lines of evidence are fossils climate clues rock and the theory of seafloor spreading?
Yes, plate tectonics is supported by various lines of evidence such as fossils showing similar species on different continents, climate clues like ancient glaciers in tropical regions, rock formations matching across continents, and the theory of seafloor spreading confirmed by magnetic striping on the ocean floor. These pieces of evidence collectively support the concept of plate tectonics and the movement of Earth's lithosphere.
What are two pieces of evidence for sea-floor spreading?
The existence of mid-ocean ridges where new oceanic crust is being formed through volcanic activity. Magnetic stripes recorded on the seafloor that show symmetric patterns of reversed and normal polarity, providing evidence of past magnetic field reversals and thus the movement of tectonic plates.
The ocean floor spreading from the ridge what are three kind of evidence scientist have found to support this ideas?
Three types of evidence supporting the idea of seafloor spreading include magnetic striping of the ocean floor (paleomagnetism), the presence of young volcanic activity near mid-ocean ridges, and the discovery of deep-sea hydrothermal vents that release hot mineral-rich water. These pieces of evidence suggest that new oceanic crust is continuously forming at mid-ocean ridges and spreading outward.
What evidence was used to support continental drift?
Evidence supporting continental drift includes the fit of the continents like pieces of a giant jigsaw puzzle, matching geological features across different continents, similarities in rock formations and mountain chains, distribution of fossils across continents, and the pattern of magnetic stripes on the ocean floor that support seafloor spreading. These pieces of evidence collectively support the theory of continental drift proposed by Alfred Wegener.
What three pieces of evidence for Wegener's theory came from the sea floor?
seafloor spreading, age of the sea floor and ocean trenches.

What do pieces of oceanic crust do during sea floor spreading?
During sea floor spreading, pieces of oceanic crust move apart as new magma rises to the surface at mid-ocean ridges. As the crust spreads, it carries with it the magnetic signature of Earth's magnetic field, providing evidence for the process of seafloor spreading.

What is the 5 pieces to prove contenential drift?
Fit of continents: The edges of continents like South America and Africa fit together like puzzle pieces. Fossil evidence: Similar fossils of plants and animals found on different continents suggest they were once connected. Rock formations: Matching rock formations and mountain ranges across continents support the idea of continental drift. Paleoclimate data: Evidence of past climates, such as glaciers in regions that are now tropical, can be explained by continental drift. Seafloor spreading: Mid-ocean ridges and magnetic striping on the seafloor provide evidence of tectonic plate movement and support the theory of continental drift.
How can a T-chart help you gather evidence?
A T-chart can help you gather evidence by organizing information into two columns: one for "pros" and one for "cons". This structure makes it easier to compare different perspectives or pieces of evidence, leading to a more balanced and comprehensive analysis of a topic or issue.
What is the difference between subduction and seafloor spreading?
Sea floor spreading is where new oceanic crust is formed through volcanic activity and then moves away from the ridge. Subduction is when one tectonic plate moves under another tectonic plate. Hope this helped :)
What are four pieces of evidence for continental drift?
Continents fitting together like a jigsaw puzzle, such as the matching coastlines of South America and Africa. Similar rock formations and mountain ranges found on different continents that line up when the continents are placed together. Fossil evidence of similar plants and animals found on different continents that were once connected. The discovery of mid-ocean ridges and magnetic stripes that indicate seafloor spreading and movement of continents.
What process in earth's interior causes subduction and sea floor spreading?
Subduction and sea floor spreading are both a result of the movement of the tectonic plates.Plate Tectonics
