Evidence about ancient climates indicate that
Glaciers once covered much of what is now India and parts of Africa
No continent occupied the Southern Hemisphere
Rafts were used to transport plants and animals to new continents
Evidence from meteorites were found in Europe.
Where do deep ocean trenches occur?
diversion boundaries
oceanic-continental convergent boundaries
subduction zones
both answers two and three
Even with the multiple pieces of evidence, why was Wegener's continental drift idea still rejected by scientists?
He didn't have a mechanism for what caused the continents to move away from one another.
Glacial striations were found on multiple continents so it was inaccurate evidence.
He couldn't clearly communicate his evidence ideas when speaking.
There wasn't enough fossil evidence to support his idea - island hopping sounded more accurate.

crust
mantle
outer core
inner core

Pegusus
Permethia
