II. Answer the following questions in about 20-25 words each:

What are fossils?
Ans: Fossils are the preserved remains or impressions of prehistoric plants or animals in rock. For animals, these are often their bones, teeth, and sometimes skin or tendons.

Why did the Brontosaurus prefer to live in water?
Ans: Brontosauruses were very large, and their legs could not support them well on land, so they preferred living in water for better support.

Why does the writer say that the ways of nature are not understandable to human beings?
Ans: The writer says this because the mighty dinosaurs, once dominant creatures on Earth, were completely wiped out due to unknown natural causes.

III. Answer the following questions in about 50-60 words each:

How do scientists know about dinosaurs?
Ans: Scientists learn about dinosaurs from fossils. They reconstruct the dinosaurs’ bodies using bones, teeth, and other hard parts. Footprints and fossilized eggs also provide information about their movement and reproductive behaviour. Over time, these remains have hardened into stone, giving scientists more insights into their lives.

Describe some of the habits of dinosaurs.
Ans: Dinosaurs were land reptiles. Some were carnivores, feeding on flesh, while others were herbivores, eating plants and leaves. Many large dinosaurs, like the Brontosaurus, spent much of their time in water to support their heavy bodies. They grazed on vegetation along the banks of rivers and lakes.

Give the probable reasons for the disappearance of dinosaurs.
Ans: Scientists aren’t completely sure why dinosaurs disappeared, but it is believed that climate changes, drying swamps, rising mountains, and colder winters made it difficult for dinosaurs to adapt. Changes in vegetation also made it hard for herbivores to find food. These factors, combined with other unknown causes, led to their gradual extinction.
