What evidence do we have for continental drift?
Evidence for continental drift includes the matching shapes of coastlines across different continents, similarities in rock formations and geological features between continents, and the distribution of fossils of the same species on different continents that were once connected. Additionally, the alignment of mountain ranges and earthquake patterns also support the theory of continental drift.
What are two forms of evidence used to support the continental drift theory?
Two forms of evidence used to support the continental drift theory are the fit of the continents (jigsaw-like arrangement of continents' coastlines) and matching geological formations (similar rock types, structures, and mountain ranges on different continents). Additionally, paleontological evidence, such as similar fossil records found across separate continents, also supports the theory.
How do mid-ocean ridges support both the idea of continental drift and the theory of plate tectonics?
Mid-ocean ridges are divergent boundaries where new oceanic crust forms, supporting the idea of continental drift by providing evidence of seafloor spreading. This process explains how continents can move apart and supports the theory of plate tectonics by demonstrating the movement of tectonic plates and the renewal of the Earth's crust.
Why would wegener have considered the presence of coal in Pennsylvania evidence of continental drift?
Wegener would have considered the presence of coal in Pennsylvania as evidence of continental drift because coal forms from the remains of ancient plants, which typically grow in swampy environments. The presence of coal in Pennsylvania suggests that the region was once located in a different climate zone, which aligns with the idea of continents moving over time. This supports Wegener's theory of continental drift, which proposed that the continents were once connected and have since moved apart.
What layer of earth forms the continents?
the crust. the layer below that is the layer of molten lava called the mantle. the continental plates move and float on this. this is known as continental drift

What are the four forms of evidence Alfred wegener used to support his hypothesis he called continental drift?
Alfred Wegener used fossil evidence (matching plant and animal species across continents), geological evidence (similar rock formations and mountain ranges on different continents), climate evidence (glacial deposits and ancient climate patterns that suggested continents were once connected), and fit of continents (the way the continents seem to fit together like a puzzle) to support his hypothesis of continental drift.
What two forms of evidence used to support continental drift?
glssopteris and other fossels were found on different contenents and could not swim across. also all of the contenents fit together like a. jiggsaw puzzle
Is the continental drift the new crust that forms magma?
yes it is

What are three forms of evidence that Wegner used to support his idea of continental drift and which interested him the most?
Geological evidence such as the matching of rock formations and mountain ranges across continents Fossil evidence, specifically the presence of identical fossils on different continents separated by vast oceans Paleoclimatic evidence, including glacial deposits and coal seams found in regions where they shouldn't be if the continents were positioned differently Wegner was particularly interested in the matching of geological features across continents, as this provided strong evidence for his theory of continental drift. Additionally, the distribution of fossils on different continents intrigued him due to the implications for how species could have migrated and evolved.

How was the forms the Mid-Atlantic Ridge?
The theory of continental drift that we gender worked out the continents were together but gradually drifted apart
How Continental drift changes earth?
continental drift can change there earth in many different ways like land forms and climates for example the Hawaiian islands were originally and under water volcano but over the years it has traveled under the crust making new land.
New oceanic lithosphere forms as a result of?
New oceanic lithosphere forms as a result of seafloor spreading at mid-ocean ridges. Magma rises from the mantle, solidifies at the mid-ocean ridge, and creates new oceanic crust. This process leads to the continuous expansion of the ocean floor.
What is a good sentence for continental drift?
The term 'continental crust' is a compound noun, a word for therelatively thick part of the earth's crust that forms the large landmasses. A noun functions in a sentence as the subject of a sentence or a clause, and as the object of a verb or a preposition. Examples:Bobby has no idea what a continental crust is. I explained to him that continental crust is land (territory).
