C Correct answer
Explanation

The Rocky Mountains formed along the western edge of Laurasia during the Mesozoic era. This was due to the collision of the North American and Pacific plates.

Multiple choice

What was the main evidence supporting Wegener's theory?

  1. Fossil record

  2. Rock formations

  3. Climate patterns

  4. Ocean currents
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Wegener's theory was primarily supported by the fossil record, which showed that similar fossils were found on different continents that are now separated by oceans.

  4. Rodinia
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, approximately 250 million years ago.

  3. About 1 million years ago

  4. About 100 years ago
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The CMB occurred about 13.8 billion years ago, which is the estimated age of the universe.

Multiple choice

What is the primary principle underlying biostratigraphy?

  1. Fossils evolve over time, and their presence or absence can be used to determine the relative age of rocks.

  2. Fossils are randomly distributed throughout the rock record, and their presence or absence cannot be used for dating.

  3. Fossils are only found in certain types of rocks, and their presence or absence cannot be used for dating.

  4. Fossils are not useful for dating rocks because they are too rare.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Biostratigraphy relies on the principle that fossils evolve over time, and the presence or absence of specific fossils in a rock layer can be used to determine the relative age of that layer compared to other layers.

Multiple choice

Which type of fossil is most commonly used for biostratigraphic dating?

  1. Index fossils

  2. Trace fossils

  3. Body fossils

  4. Microfossils
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Index fossils are fossils of organisms that are widely distributed, easily recognizable, and have a short geologic range, making them useful for precise dating and correlation of rock layers.

Multiple choice

  2. Mesozoic

  3. Paleozoic

  4. Precambrian
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Mesozoic Era, also known as the Age of Dinosaurs, lasted from approximately 252 to 66 million years ago and is characterized by the dominance of dinosaurs as the dominant terrestrial vertebrates.
