How Much Do You Know About Jurassic Period?

Explanation
The correct answer is both a & b. The Jurassic Period started at the end of the Triassic Period and continued into the beginning of the Cretaceous Period. This period is known for the dominance of dinosaurs and the evolution of many new species. It is defined by specific geological and fossil evidence, making it a distinct period in Earth's history.

Explanation
The correct answer is "All of the above" because the Jurassic period is divided into three distinct periods: Early, Middle, and Late. These periods are determined based on the age of the rock formations and the fossils found within them. Each period represents a different stage in the evolution and development of life during the Jurassic era. Therefore, selecting "All of the above" encompasses all three periods correctly.

Explanation
The period mentioned in the question lasted for approximately 56 million years. This means that the specific time frame being referred to lasted for this duration.

Explanation
The statement that T. Rex lived in the Jurassic period is false. T. Rex, also known as Tyrannosaurus Rex, lived during the Late Cretaceous period, which was after the Jurassic period. T. Rex existed around 68 to 66 million years ago, while the Jurassic period occurred between 201.3 and 145 million years ago. Therefore, T. Rex did not live in the Jurassic period.

Explanation
Approximately 65 million years after the extinction of dinosaurs, people appeared on Earth. This is based on scientific evidence and fossil records that suggest dinosaurs went extinct around 65 million years ago, and the earliest human ancestors appeared around 6 million years ago. The time gap between the extinction of dinosaurs and the appearance of humans is a significant period in Earth's history.

Explanation
During the Jurassic period, a day was 23 hours long. This can be inferred from scientific studies and geological evidence that suggest the Earth's rotation has been gradually slowing down over time. By analyzing the growth rings of ancient corals and studying the fossil record, researchers have been able to estimate the length of a day during different geological periods. In the case of the Jurassic period, the evidence points to a day lasting 23 hours.

Explanation
Allosaurus being the top predatory dinosaur of the late Jurassic period in North America is supported by scientific evidence and fossil records. Allosaurus was a large carnivorous dinosaur with sharp teeth and strong jaws, making it an apex predator in its ecosystem. Fossils of Allosaurus have been found in various locations in North America, further confirming its dominance as a top predator during the late Jurassic period.

Explanation
The sandstone monoliths in Utah's Capitol Reef National Park were dubbed as the Temple of the Sun and the Temple of the Moon. Both names were given to these towering rock formations that rise above the desert flats in the park.

Explanation
The explanation for the given correct answer is that domelike mogotes in Valle de Viñales National Park, Cuba, evolved from a blanket of fog. This means that over time, the fog has played a significant role in shaping the landscape and forming these unique geological features. Fog can contribute to the erosion and weathering of rocks, leading to the formation of mogotes. This process takes place over a long period, gradually transforming the landscape into its current domelike shape. Therefore, the statement "True" is the correct answer.

Explanation
A tuatara does not look similar to its Jurassic relatives. While tuataras are reptiles that have been around since the time of the dinosaurs, their appearance has evolved over millions of years. They have unique physical characteristics, such as a spiky crest on their back and a third eye on top of their head, which set them apart from their Jurassic relatives. Therefore, the statement that a tuatara looks similar to its Jurassic relatives is false.
