TCAP Success Grade 8 ELA Chapter 5 Sample

Read the passages and answer the questions that follow.

Passage 1:

Have you ever wondered why you have never seen a living Tyrannosaurus rex or Velociraptor? These large animals, along with many other species of dinosaur, all became extinct about 65 million years ago. The reason for the mass extinction of over half of Earth’s species is most likely an impact of a huge meteorite. Scientists have discovered a layer of the Earth’s crust that dates to 65 million years ago, which contains large amounts of the element iridium. This element is rare on the Earth’s surface; however, iridium is quite common in meteorites. A crater found in Mexico, also dating back to 65 million years ago, indicates that the iridium probably arrived when an asteroid or comet struck the Earth. The impact would have distributed iridium around the world while also kicking up dust and debris. The debris would have blocked sunlight and hindered plants’ ability to generate energy, causing them to die off. As plants died away, herbivores would lose their food sources and become extinct as well. Ultimately, large carnivores, including T. rex, would follow suit.

Passage 2:

About 65 million years ago, all the large land-dwelling dinosaurs and many other forms of life on Earth became extinct. This mass extinction event, known as the Cretaceous-Paleogene event, was brought on by a number of geological occurrences. First, widespread volcanic eruptions released high levels of dust and greenhouse gases into the atmosphere. The dust interfered with sunlight, killing off many plants, while the gases caused a rapid temperature spike. These changing conditions would have caused a slow extinction between 68 and 66 million years ago. Around the same time, sea levels dropped. Dropping sea levels led to decreased marine diversity and further climate change, causing stress to life on land. About 65 million years ago, an asteroid struck the Yucatan Peninsula in Mexico, launching more dust into the atmosphere and further blocking light. Some scientists claim that the asteroid impact alone is a sufficient explanation for the mass extinctions. However, only a combination of factors, including reduced sea levels and increased volcanic activity, would provide the right environment for the extinctions to occur.
