Imagine that you set your watch to the Greenwich Mean Time

the stick casts the shortest shadow, your watch reads 8 am. Your
watch is still set to GMT. What is your longitude? - ANS 60
degrees east (idk why)
Evidence for Continental Drift - ANS 1) Fits of continental edges
across the Atlantic Ocean
2) Findings of certain recurring fossils across continents
3) Rock types and Structural similarities
4) Distribution of glacial deposits
5) Paleoclimatic belts/ evidence

ANS 45 degrees.
Rotates 15 degrees each hour; will rotate full 360 degrees in 24
hours

of Earth is: - ANS liquid (not solid)
Wegener called Earth's single supercontinent ____________. -
ANS Pangea
