2 What was probably the first evidence that led some to suspect the continents were once connected?
The matching coastlines and geologic similarities between continents, specifically between South America and Africa, led some to suspect that the continents were once connected. This evidence, known as continental drift, was proposed by Alfred Wegener in the early 20th century.
How do we know that the continents have moved?
The theory of plate tectonics provides evidence that continents have moved over time. This evidence includes matching geological features between continents that were once part of the same landmass, like the coastlines of Africa and South America. Additionally, the distribution of fossils and the alignment of mountain ranges suggest that continents were once connected and have since drifted apart.
What are the evidence supporting the existence of Pangaea?
Fossil evidence: Identical fossils of plants and animals have been found on continents that are now widely separated, suggesting they were once connected. Geological evidence: Matching rock formations and mountain ranges on different continents provide evidence of their past connection. Climate evidence: Similar coal deposits and glacial striations found across continents support the idea of a single supercontinent with a consistent climate.
What evidence proves that Pangaea once existed?
Evidence to support the theory of Pangaea includes the fit of continents like South America and Africa, the distribution of similar fossils and rock formations across continents, and matching mountain ranges and geological structures on different landmasses. Furthermore, the study of plate tectonics has provided additional evidence by explaining how continents have moved over time.
What are 3 pieces of evidence that support the idea of continental drift?
Matching geological formations: Similar rock formations and mountain ranges are found on opposite sides of the Atlantic Ocean, suggesting they were once connected. Fossil evidence: Similar plant and animal fossils found on different continents suggest they were once part of the same landmass. Paleoclimatic evidence: Past climate data, such as glacial striations and ancient climate indicators, support the idea that continents were once positioned differently.
What is evidence that Africa was once cold?
glossopteris
Evidence that Africa was once cold?
Fossil, climate, and rock.
The geographic distribution of the swimming reptile Mesosaurus provides evidence that .?
South america and Africa were once joined.
What is the evidence that Africa and Europe were once joined?
Well , fossils were found ! : D
How did wegner use climate evidence to support his evidence?
In Africa there are scratch marks that could only have been caused by glaciers but Africa is by a hot place by the equate so once it was colder there
What evidence does the geographic distribution of the swimming reptile Mesosaurus provide?
South America and Africa were once joined.
How did wegner use climate evidence to support his hypothosis?
In Africa there are scratch marks that could only have been caused by glaciers but Africa is by a hot place by the equate so once it was colder there
What evidence does the continental drift have that the continents were once connected?
Evidence for continental drift includes the fit of continents like South America and Africa, similar rock formations and mountain ranges on different continents, and the distribution of fossils that were once found on now widely separated landmasses. These pieces of evidence suggest that the continents were once connected in a single landmass called Pangaea.
How cold is it in South Africa?
Its not cold its warm in south Africa :) What about the Drakensburg escarpments, there is snow there in winter
Which evidence exists of a migration in ancient Africa?
Linguistic Evidence
Evidence that north America and Africa was once joined?
Fossils of the glossopteris fern, which have been found across South America, Africa, India, Antarctica, and Australia. Fossil eveidence of a triassic land reiple lystrosaurus are also found across Africa, India, Antarctica and Australia.
What is a cold desert of Africa?
Africa has no cold deserts but the Namib Desert is classified as a cool coastal desert.
