What is the difference between the Paleozoic, Mesozoic, and Cenozoic Eras? (Provide details for each era)
Paleozoic Era- The part of geologic time that lasted from about 541 to 252 million years ago. In this era, fish, insects, amphibians, plants, and reptiles were dominant.
Mesozoic Era- The part of geologic time that lasted from about 252 to 66 million years ago, often called the "Age of Dinosaurs" or "middle life." During this era, dinosaurs dominated the Earth, while birds, mammals, and plants began to develop. It ended with a mass extinction that wiped out the dinosaurs.
Cenozoic Era- The era that began about 66 million years ago and continues to this day. Also known as the "Age of Mammals". Many species began to further develop, and humans started to appear.
What was the Cretaceous-Paleogene Extinction Event?
A. A small event that only affected plants
B. A mass extinction that occurred about 66 million years ago and marked the beginning of the Mesozoic Era
C. A mass extinction that occurred about 66 million years ago, marked the end of the Mesozoic Era, and caused dinosaurs and many other species to become extinct, likely due to a large asteroid impact and environmental changes
D. An event where mammals first appeared
C. A mass extinction that occurred about 66 million years ago, marked the end of the Mesozoic Era, and caused dinosaurs and many other species to become extinct, likely due to a large asteroid impact and environmental changes
Which of the following best describes a mammal?
A. A vertebrate whose body temperature is determined by its environment and has scales
B. A vertebrate whose body temperature is regulated by its internal heat, and that has skin covered with hair or fur and glands that produce milk to feed its young
C. An animal without a backbone that lays eggs
D. A cold-blooded animal that lives in water
B. A vertebrate whose body temperature is regulated by its internal heat, and that has skin covered with hair or fur and glands that produce milk to feed its young
What is the difference between Eons, Eras, and Periods? (Provide details for each one)
Eons- The largest division of time on the geological scale. Spans billions of years.
Era- A long and distinct period of history with a particular feature or characteristic. It spans hundreds of millions of years.
Period- A subdivision of time characterized by unique geological conditions and specific changes in the Earth's geology. Spans from tens to hundreds of millions of years.
