Text Book Questions & Answers - NCERT Exercises

Direct from assessment (page 336). Answers based on chapter content, point-wise for exams.

Long Answer Questions

1. Write down the use of Variometer in paragliding.

Answer:

Main purpose: Help pilot find/stay in thermal core for height gain; indicate sinking air to find rising.
Features: Audio signals (beeps increase pitch/tempo in ascent, drone deepens in descent); visual display; shows altitude (takeoff/sea level/flight level).

2. Explain ‘tow-surfing’.

Answer:

Definition: Associated with big wave surfing; motorized vehicle (e.g., personal watercraft) tows surfer into wave front.
Purpose: Matches large wave speed (higher than self-propelled); helps access deep faces.

3. Discuss the safety measures to keep in mind during paragliding.

Answer:

Certified/skilled before starting.
Carry instruments: Variometer, GPS, Radio for dangers.
Wear gear: Helmet, knee/chest guards, protective equipment.
Assisted by licensed personnel.
Inspect brakes/lines regularly.
Practice before long routes.
Maintain physical/mental fitness for quick decisions.

4. Briefly explain Sea beds and Rip Currents.

Answer:

Seabed: Poses danger in falls; wave tumbles surfer down to shallow reefs/beaches (low tide); serious injuries/kills from collisions.
Rip Currents: Channels flowing from shore; appear flat, carry swimmers out beyond waves; up to 50 ft wide; exit by paddling parallel to shore.

5. How does Global Positioning System work?

Answer:

Necessary for competitions; records flight track for technique analysis/sharing.
Determines wind drift at altitude; provides position to avoid restricted airspace.
Identifies location post-landing for retrieval in unfamiliar areas.

Short Answer Questions

1. Name the person who invented paragliding.

Answer: No single inventor; key: Domina C. Jalbert (1954 governable parachutes); term coined by Patrick Gilligan/Bertrand Dubois (1985 manual).

2. Name the two flying techniques in paragliding.

3. Classify the categories of adventure sports.

Answer: 1. Adventure water sports, 2. Adventure land sports, 3. Adventure air sports.

4. In which year, the first world championship for surfing was held?
