3. It is a matter of great pleasure & pride for us to introduce
you all this english presentation “adventure”. This project
has not only helped us understand the topics clearly but
also developed & sharpen our skills.
We would like to thank our teacher Mrs. Ritu srivastava
for this interesting project. It is her inspiration that has
encouraged us to bring up this presentation. We
hope, with our earnest efforts ,this project will surely
express our understanding towards the subject .

4. Adventure
An adventure is an exciting or unusual experience. It
may also be a bold, usually risky undertaking, with
an uncertain outcome. Adventures may be activities
with some potential for physical danger such as
skydiving, mountain climbing, river rafting or
participating in extreme sports. The term also
broadly refers to any enterprise that is potentially
fraught with physical, financial or psychological risk,
such as a business venture, or other major life
undertakings.

5. Why Adventure ?
Adventurous experiences create psychological arousal, which can be interpreted as
negative (e.g. fear) or positive (e.g. flow), and which can be detrimental as stated by
the Yerkes-Dodsonlaw. For some people, adventure becomes a major pursuit in and
of itself.
Outdoor adventurous activities are typically undertaken for the purposes of recreation
or excitement, examples are adventure racing and adventure tourism. Adventurous
activities can also lead to gains in knowledge, such as those undertaken by explorers
and Adventure education intentionally uses challenging experiences for learning.

6. What they said……..
According to adventurer André Malraux,
in his book La Condition Humane , "If a
man is not ready to risk his life, where is
his dignity?".
Helen Keller stated that "Life is either a
daring adventure or nothing."
J.M.Barrie said “To die would be an
awfully big adventure”
Andre Gide quoted “It is only in

7. • Caving — also traditionally known as spelunking
in the United States and Canada and potholing in
the United Kingdom and Ireland — is the
recreational pastime of exploring wild cave
systems.
• Caving is often undertaken for the enjoyment of
the outdoor activity or for physical exercise, as
well as original exploration.
• Caving has also been described as an
"individualist's team sport.
• Physical or biological science is also an
important goal for some cavers, while others are
engaged in cave photography.
• In well-explored regions (such as most developed
nations), the most accessible caves have already
been explored, and gaining access to new caves
often requires cave digging or cave diving. 5

8. Caving equipments
• Coveralls, helmet-mounted lights, heavy
boots and gloves.
• Halogen lamps
• A warm base layer in cold caves and light
clothes in warm caves.
• First-aid kits, emergency equipment, and
food.
• Rappel rack

9. The challenges involved in caving
The total absence of light beyond the entrance the
negotiation of pitches and squeezes.
Water hazards.
Cave diving is a distinct, and much more
hazardous, sub-specialty undertaken by a small
minority of technically-proficient cavers.
Hypothermia, falling, flooding, falling rocks and
physical exhaustion are the main risks.
Cave passages look different from different
directions.

10. History of caving
Caving was pioneered by Eduard-Alfred Martel (1859–1938) who first
achieved the descent and exploration of the Gouffre de Padirac, France
as early as 1889 and the first complete descent of a 110 metre wet
vertical shaft at Gaping Gill, in Yorkshire, England in 1895. He
developed his own techniques based on ropes and metallic ladders.
Martel visited Kentucky and notably Mammoth Cave National Park in
October 1912. In the 1920s famous US caver Floyd Collins made
important explorations in the area and in the 1930s, as caving became
increasingly popular, small exploration teams both in the Alps and in
the karstic high plateaus of southwest France (Causes and Pyrenees)
transformed cave exploration in both a scientific and recreational
activity. The scaling-pole (1940), nylon ropes (1942), use of explosives
in caves (1947) and mechanical rope-ascenders (Henri Brenot's
"monkeys", first used by Chevalier and Brenot in a cave in 1934) can
be directly associated to the exploration of the Dent de Crolles cave
system.

11. Paragliding
Also known as parascending or parakiting is majorly
a recreational kiting activity where a person is
towed behind a vehicle [usually a boat] while
attached to a specially designed canopy wing [like a
parachute] .
Parasailing is one of the fastest growing sports in
the nation.
Para-sails can be generally be seen in beach resorts
destination.

12. History
1962- A French engineer by the name of Pierre-
Marcel, developed the Ascending-Gliding
Parachute. Lemoigne’s concept was achieved by
modifying a Para Commander design was based
on the 24 – gore ‘suspension line ‘ parachute that
incorporated steering slots making it very
maneuverable on descent and parachute of
choice for most skydivers and the military .
Lemoigne sealed the top steering and exhaust
vents allowing on oncoming air flow to be
redirected to provide lift.

13. Difficulties in Parasailing
The boat should be stopped completely just before splashdown to
avoid dragging the flyer and chute through the water.
Weather problems.
Tidal speed.
The person doing parasailing is inexperienced.
Emergency landing is not possible .

14. Requirements for Para-sailing
• A boat with a minimum of 100 HP.
• 300 feet as the standard tow rope .
• A skilled driver and observer, a two man
ground crew, favorable winds.
• Wind speed should not exceed 15 mph.
• A helmet, approved life vest, and foot
protection
