Which of the following dinosaurs did not live during the Cretaceous Period?
Correct Answer
C. Diplodocus
Explanation
Diplodocus did not live during the Cretaceous Period. Diplodocus was a long-necked herbivorous dinosaur that lived during the Late Jurassic Period, around 154-152 million years ago. The Cretaceous Period occurred after the Jurassic Period, from 145-66 million years ago. Therefore, Diplodocus existed before the Cretaceous Period and is not a dinosaur that lived during that time.
2.
Dinosaurs ate:
Correct Answer
E. Both A and B
Explanation
Dinosaurs were a diverse group of reptiles, and their diet varied depending on the species. Some dinosaurs were carnivorous and primarily ate meat, while others were herbivorous and consumed plants. Therefore, the correct answer is "both A and B" because some dinosaurs ate meat, while others ate plants.
3.
Carnivores ate only
Correct Answer
A. Meat
Explanation
Carnivores are animals that primarily consume meat as their main source of nutrition. They have specialized adaptations like sharp teeth and claws to help them catch and consume other animals. Therefore, the correct answer is "meat."
4.

5.
A scientist who studies prehistoric life is a:
Correct Answer
C. Paleontologist
Explanation
A paleontologist is a scientist who studies prehistoric life, including the fossils of plants, animals, and other organisms. They analyze and interpret these fossils to understand the history of life on Earth, including the evolution of different species and the environments they lived in. Paleontologists often work in collaboration with biologists and geologists, but their specific focus is on the study of ancient life forms and their interactions with the Earth's ecosystems.

Evidence that the asteroid hit on the northwest corner of the Yucatan Peninsula includes:
Correct Answer
D. All of the above
Explanation
The correct answer is "All of the above" because all three pieces of evidence mentioned in the question support the claim that the asteroid hit on the northwest corner of the Yucatan Peninsula. The large crater approximately 200 km in diameter is a physical feature that indicates a significant impact. The increase in iridium in the clay layer as you get closer to this location suggests that the asteroid, which is rich in iridium, was responsible for the deposit. The presence of shocked quartz is another characteristic of a massive impact event. Therefore, all three pieces of evidence together provide strong support for the asteroid hit in the northwest corner of the Yucatan Peninsula.
7.
Which of the following are possible theories in the extinction of dinosaurs?
Correct Answer
E. All of the above
Explanation
All of the options listed, including large asteroid impact, disease, volcanism, and the breakup of Pangea, are possible theories in the extinction of dinosaurs. The large asteroid impact theory suggests that a massive asteroid collision with Earth caused widespread devastation and climate change, leading to the extinction event. Disease could have played a role in the decline of dinosaur populations, as it can weaken and kill individuals. Volcanism, specifically massive volcanic eruptions, could have released large amounts of ash and gases into the atmosphere, causing global cooling and environmental changes. The breakup of Pangea, the supercontinent, could have altered habitats and disrupted ecosystems, contributing to the extinction.
8.
The Triceratops has how many horns?
Correct Answer
B. 3
Explanation
The Triceratops has three horns. This is a well-known fact about the Triceratops, as its name actually means "three-horned face" in Greek. The Triceratops had a large horn on its nose and two smaller horns above its eyes. These horns were likely used for defense and display purposes, making the Triceratops a formidable and impressive dinosaur.
