SCIENCE WEEK 6 - EVIDENCES OF PLATE MOVEMENTS Flashcards
hypothesized that all of the modern-day continents had
previously been clumped together in a supercontinent
he called Pangaea
Alfred Lothar Wegener
Any evidence of past life preserved in geologic context; They are a tangible connection to life, landscapes, and climates of the past.
They show us how life, landscapes, and climate have changed over time and how living things responded to those changes.
Paleontological Evidence
is the scientific study of life of the geologic past that involves the analysis of plant and animal fossils
Paleontology
a French Scientist, argued that the presence of identical fossil
plants in both North American and European coal deposits
could be explained if the two continents had formerly been connected
Antonio Snider Pellegrini
described how plants in Late Paleozoic coal beds of India, Australia,
South America were all similar
Edward Seuss
Is an interval of time withinthe ice age that is marked by
colder temperature and glacier advances
Glaciation
Alfred Wegener proposed that the rock layers were made when all the continents were part of Pangaea
Evidence from Structure and Rock Type
is the study of climactic conditions of past geologic ages.
Paleoclimatology
it is the study of ancient magnetic field directions by studying the magnetism frozen into rocks of different ages
Paleomagnetism
the apparent movement of themagnetic poles illustrated in magnetized rocks
Polar Wandering
