Students have asked these similar questions
Place these events in the history of life on Earth in the order that they occurred. a. accumulation of O2 in Earth’s atmosphere b. colonization of land by plants and fungi c. diversification of animals (Cambrian explosion) d. origin of eukaryotes e. origin of humans f. origin of multicellular organisms g. origin of prokaryotes
The Cambrian Explosion occurred approximately 542 million years ago. During the Cambrian, what ‘exploded’?
a. The diversity of species on Earth, including many major animal phyla that exist today
b. The Yucatan Peninsula, which was hit by an asteroid
c. The quantity of oxygen in the atmosphere due to the expansion of coniferous forests
d. Numerous volcanoes worldwide, leading to the fourth mass extinction
We live in the Cenozoic era, and scientists know more
about this era and the epochs it’s divided into than any other time period. Why is this?
A. We know more about the Cenozoic era because this is the only era that has had a wide diversity of species living on Earth.
B. We know more about the Cenozoic era because this is the most recent time period in the history of the Earth, and we have more information available to study.
C. We know more about the Cenozoic era because the planet’s poles reversed magnetic fields at the beginning of this era.
D. We know more about the Cenozoic era because fossils don’t exist to document previous eras.
