NCERT MCQ Solutions for Class 5 EVS Looking Around Chapter 10 Walls Tell Stories

Many ancient forts feature bastions (burj), which are fortified structures projecting from the main wall. They were built to provide better angles for defense and surveillance.

Sharp iron spokes on fort gates were a defensive measure. They were designed to injure and deter war elephants that were used to ram and break down the gates.

Bastions were built higher than the walls to give soldiers a clear, wide-angle view of approaching enemies, which greatly improved the fort’s security and defensive capabilities.

Ancient engineers used sophisticated systems to lift water. Animals like bullocks powered large wheels that lifted pots of water, which then flowed through pipes to higher levels.

Some forts were designed with advanced acoustics. A clap or shout at the entrance could travel clearly to the highest point, serving as an effective warning system.

Ancient forts were hard to conquer due to strong defenses. These included very thick walls, high bastions for surveillance, and deep ditches or moats surrounding them.

Many historical cannons were cast from bronze, an alloy of copper and other metals like tin. Bronze is strong, durable, and resistant to corrosion, making it ideal.

The remains of palaces, houses, workshops, and areas for farming and water storage indicate a fort was a self-sufficient city, not just a military post.

Many grand stone forts seen today began as simpler mud structures. Some date back to the medieval period (around the 12th-13th centuries) and were expanded by later rulers.

A major issue at historical sites is vandalism. Visitors often deface ancient walls by writing or scratching their names on them, causing irreversible damage to a shared heritage.

A deep ditch or moat served as a primary defensive barrier. It made it very difficult for an enemy army to approach the walls with soldiers or heavy siege equipment.

In ancient water systems, bullocks provided the power. By walking in a circle, they turned large wooden gears or wheels, which in turn lifted water from a well.

Even broken pieces of pottery are valuable historical artifacts. Their design, material, and craftsmanship can tell us about the daily life, art, and technology of past civilizations.

The phrase “walls tell stories” means a building’s architecture, materials, and even its damage can reveal information about the people who built it, their technology, and their history.

A ruler’s interest in the arts can be seen through historical records of their patronage. Support for musicians, dancers, and artists reflects a thriving cultural environment.

Stone carvers were constantly exposed to fine dust from chiseling. Inhaling this dust over many years could lead to serious and sometimes fatal lung diseases.

A map uses a scale to show how distances on the map relate to real-world distances. For example, a scale might state that 1 cm equals 110 meters.

The system of interlocking gears used in some ancient water wheels works on a similar mechanical principle to the gear system found on a modern multi-speed bicycle.

The existence of working fountains on the upper levels of an old fort is proof of advanced hydraulic engineering, showing a mastery of water pressure and transport systems.

Museums are crucial because they collect and preserve historical artifacts. These objects provide a direct connection to the past, helping us learn about different cultures and their technologies.
