How long was it before new evidence emerged to support wegeners theory of the continental drift?
New evidence supporting Alfred Wegener's theory of continental drift began to emerge in the late 1940s and early 1950s, approximately 30 years after he first proposed the theory in 1912. The development of plate tectonics, particularly the discovery of seafloor spreading and paleomagnetism, provided crucial evidence that validated Wegener's ideas. This shift in understanding revolutionized geosciences and established a comprehensive framework for explaining the movement of continents.
What did Albert Einstein think of plate tectonics?
When Einstein died in 1955 the theory was not yet known as plate tectonics, it was called continental drift and had almost no evidence supporting it. It was not until the early 1960s that the discovery of the magnetic stripes on the oceanic floor demonstrated a practical mechanism by which the theory could operate. Therefore I doubt he had much of an opinion on the theory (also it was not in his field of expertise).
Which statements are true regarding scientific evidence supporting the big bang theory CMB radiation and a very early form of helium were discovered. The universe has structure and uniformity. Redshif?
The statements that are true regarding scientific evidence supporting the Big Bang theory include the discovery of cosmic microwave background (CMB) radiation, which is a remnant of the early universe and provides strong evidence for the Big Bang. Additionally, the observed redshift of distant galaxies supports the expansion of the universe, indicating that it was once much smaller and denser. The presence of helium in the universe, formed during the Big Bang nucleosynthesis, further corroborates this theory. Overall, the universe exhibits both large-scale structure and uniformity, consistent with predictions made by the Big Bang model.
What scientist did not have experimental evidence to support his theory of the atom?
John Dalton did not have experimental evidence to support his theory of the atom when he proposed it in the early 19th century. His atomic theory was based on observational patterns rather than direct experimental data.
Who discovered the second piece of evidence that supports the big bang theory?
The second major piece of evidence supporting the Big Bang theory was the discovery of cosmic microwave background radiation (CMB), which was made by Arno Penzias and Robert Wilson in 1965. This faint radiation, uniform across the universe, is considered a remnant of the hot, dense state of the early universe. Their discovery provided crucial support for the Big Bang model, confirming predictions made by cosmologists about the early universe's conditions.
What is one major piece of evidence that supports the validity of the Big Bang theory?
One major piece of evidence supporting the validity of the Big Bang theory is the cosmic microwave background radiation, which is a faint glow of radiation that fills the universe and is considered a remnant of the early stages of the universe's expansion.
What period of time was evidence supporting continental drift?
The evidence supporting continental drift emerged in the early to mid-20th century, with key contributions from scientists like Alfred Wegener and Arthur Holmes. By the 1960s, advancements in technology, such as ocean floor mapping and paleomagnetism, provided further support for the theory.
Where did the earliest humans to visit North America probably come from?
The likely origin of the first visitors to North America is Central Siberia, located in northwestern Asia. Evidence supporting the theory include genetic comparisons between early native Americans and early Siberians, and etymological evidence, comparing the early languages of the Inuit and Indians with that of Asian languages.
Evidence that supports the theory of evolution of the studies of what?
Evidence supporting the theory of evolution comes from various fields, including genetics (DNA similarities between species), paleontology (fossil record showing transitional species), embryology (similarities in early stages of development), and biogeography (distribution of species across different regions). These studies collectively provide strong evidence for the process of evolution by natural selection.
Where does one early piece pieceof evidence that the continents were once joined together in a single large continents come from?
One early piece of evidence is the remarkable fit of the coastlines of South America and Africa, suggesting they were once part of the same landmass. This observation was noted by Abraham Ortelius in 1596 and later popularized by Alfred Wegener as part of his theory of continental drift.
What was the first evidence that led people to think that the continents were once connected?
The first evidence that led people to think that the continents were once connected because of earthquakes

Why embryos used as evidence of evolution?
Embryos are used as evidence of evolution because they display striking similarities across different species during early development. These similarities suggest a common ancestry, supporting the theory of evolution. The study of embryonic development provides insights into the evolutionary relationships between species.

What is the coastal route theory?
The coastal route theory suggests that early human populations migrated from Asia to the Americas along the Pacific coastline, utilizing boats and coastal resources. This theory posits that these early migrants traveled through a series of coastal habitats, which provided ample food and shelter, facilitating their movement. Evidence supporting this theory includes archaeological findings of ancient sites along the coast and the presence of maritime adaptations in these populations. It contrasts with the more traditional land-based route theories, emphasizing the importance of marine environments in early human migration.
