Write true or false in the blank following each statement to indicate whether it is accurate or not.
a) the existence of the supercontinent pangea led to a high degree of geographic uniqueness (endemism) among species during the late triassic.
b) the jurassic period marks the time when dinosaurs began to dominate among terrestrial vertebrates.
c) the scarcity of sediments from the middle jurassic may explain the apparent decrease in dinosaur diversity during this time.
d) mammals and dinosaurs co-existed throughout the jurassic and cretaceous periods.
e) the greatest leap in dinosaur diversity occurred during the jurassic period.
f) there is a correlation between the rise of angiosperms and the diversity of herbivorous dinosaurs during the cretaceous period.
g) there is a significant body of evidence suggesting that dinosaur evolution was responsible for the simultaneous evolution of angiosperms.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
