4. Write how the use of science and technology has changed the system of water and air transportation.
Ans: The use of science and technology has changed the system of water and air transportation are mentioned below:
(i) Water Transportation:
(a) Advanced Materials: Modern ships are constructed with lightweight, durable materials like advanced composites and alloys, improving fuel efficiency and durability.
(b) Hydrodynamics: Improved understanding of hydrodynamics has led to better hull designs that reduce drag and increase speed and fuel efficiency.
(ii) Navigation and Safety:
(a) GPS and Satellite Navigation: GPS and other satellite-based navigation systems provide precise positioning, route planning, and real-time updates, enhancing safety and efficiency.
(b) Autonomous Ships: Development of autonomous and semi-autonomous ships equipped with advanced sensors and AI for navigation and operations is reducing the need for large crews and minimising human error.
(iii) Propulsion Systems:
(a) Efficient Engines: Modern engines, such as dual-fuel engines that can run on both traditional fuels and LNG (liquefied natural gas), reduce emissions and improve fuel efficiency.
(b) Electric and Hybrid Propulsion: The use of electric and hybrid propulsion systems is becoming more common, further reducing the environmental impact of shipping.
(iv) Environmental Technologies:
(a) Ballast Water Treatment Systems: Technologies to treat ballast water reduce the transfer of invasive species between ecosystems.
(b) Emission Control: Advanced scrubbers and other emission control technologies help reduce pollutants like sulphur oxides (SOx) and nitrogen oxides (NOx) from ship exhaust.

5. Give three arguments in favour of the statement that ‘Transport’ systems are veins and arteries of a country?
Ans: Three arguments in favour of the statements of ‘transport’ system are veins and arteries of country of a country are mentioned below:
(i) Economic Vitality: Transport systems are crucial for the economic vitality of a country. They facilitate the movement of goods and services, enabling trade and commerce. Efficient transportation networks lower the costs of goods, increase market accessibility, and help businesses to thrive. Without robust transport systems, economic activities would be severely hampered, leading to stagnation and inefficiencies.
(ii) Social Connectivity: Transport systems connect people, fostering social cohesion and integration. They allow for mobility within and between urban and rural areas, making it possible for individuals to access education, healthcare, and employment opportunities. By linking diverse regions, transportation helps bridge social divides and enhances the quality of life.
(iii) National Security and Emergency Response: Effective transport systems are essential for national security and emergency response. They enable the rapid movement of military personnel and equipment during times of national defence needs. Additionally, in the event of natural disasters or emergencies, well-developed transport networks facilitate quick and efficient evacuation, delivery of relief supplies, and mobilisation of rescue operations.
6. Write the names of the following with the help of an atlas:
(a) Names of the district headquarters in Assam connected by nation.
Ans: The district headquarters in Assam connected by nation are mentioned below:
(i) Guwahati (Kamrup Metropolitan).
(ii) Nagaon (Nagaon).
(iii) Jorhat (Jorhat).
(iv) Dibrugarh (Dibrugarh).
(v) Silchar (Cachar).
(vi) Tezpur (Sonitpur).
(vii) Lakhimpur (North Lakhimpur).
(viii) Kokrajhar (Kokrajhar).
(ix) Bongaigaon (Bongaigaon).
(x) Dhubri (Dhubri).
(b) Names of the north-eastern states of India not connected by highways.
Ans: North-eastern states (Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Tripura, and Sikkim) have some level of highway connectivity.
