ENVIRONMENT:CAVE CREATION

0

Caves can for many where whether it’s in the surface of the Earth,underwater or even inside mountains.In fact,any lump of rock has the potential to turn into a cave because they’re created by erosion, which can happen by a number of means. The most common kind of cave is called a solution cave. These tend to be made of rocks such as limestone or gypsum, as they dissolve faster in water than other kinds of rock. Water falling as rain collects carbon dioxide from the atmosphere before descending through the ground. The carbon dioxide mixed with rainwater can form carbonic acid, which is a key ingredient in dissolving the rock, especially in places where there is an existing fi ssure. Further erosion and collapse transforms these cracks into networks of tunnels and caves. The water will either stay in the base of the cave once it reaches rock that it can’t dissolve, or flows out through a hole to begin the whole process again. Some of the most incredible formations in cave structures are stalactites and stalagmites. Stalactites are the pointy shards that descend from the roof of a cave. These are created when the dripping rainwater collects calcium carbonate on its way through the rock. Once it reaches the open space the calcium carbonate solidifies. This builds up as water drips along the stalactite before hardening. Stalagmites are made of calcium carbonate too, but build from the base of the cave upward if the water has dripped down before becoming solid. Underwater and overground caves are formed in similar ways. Rock is repeatedly attacked by a force of nature, such as ocean tides, winds or sand. This bombardment wears away at the rock, creating a dent that gets steadily bigger until a cave is formed

Four main types of cave 
Solution cave 
This is the most common kind of cave in the world. Formed from water moving through carbonate or sulphate rock, these types of cave grow to form some of the largest caverns on Earth.

Lava cave 

Created when lava is fl owing along a path and part of it cools and hardens. This leaves the still molten lava inside to continue fl owing, ultimately resulting in hollow lava tubes.

Glacier cave 

The most common cause is melt water running through, or under, the glacier. This widens crevices and carves out chutes, which will then increase in size during the summer months.

Sea cave 

Underwater and coastal rocks are constantly battered by waves. This action erodes the weaker parts of the rock. Some of these get flooded and become underwater cave systems.

WALT DISNEY FAMOUS QUOTATIONS

1

Walter Elias "Walt" Disney (December 5, 1901 – December 15, 1966) was an American film producer, director, screenwriter, voice actor, animator, entrepreneur, entertainer, international icon, and philanthropist, well known for his influence in the field of entertainment during the 20th century. Along with his brother Roy O. Disney,he was co-founder of Walt Disney Productions, which later became one of the best-known motion picture producers in the world. The corporation is now known as The Walt Disney Company and had an annual revenue of approximately US$36 billion in the 2010 financial year.Disney is particularly noted as a film producer and a popular showman, as well as an innovator in animation and theme park design. He and his staff created some of the world's most well-known fictional characters including Mickey Mouse, for whom Disney himself provided the original voice. During his lifetime he received four honorary Academy Awards and won 22 Academy Awards from a total of 59 nominations, including a record four in one year, giving him more awards and nominations than any other individual in history. Disney also won seven Emmy Awards and gave his name to the Disneyland and Walt Disney World Resort theme parks in the U.S., as well as the international resorts Tokyo Disney Resort, Disneyland Paris, and Hong Kong Disneyland.
The year after his December 15, 1966 death from lung cancer in Burbank, California, construction began on Walt Disney World Resort in Florida. His brother Roy Disney inaugurated the Magic Kingdom on October 1, 1971.

WALT DISNEY FAMOUS QUOTATIONS

The flower that blooms in adversity is the rarest and most beautiful of all.

All our dreams can come true, if we have the courage to pursue them.

What ever you do, do it well. Do it so well that when people see you do it they will want   to come back and see you do it again and they will want to bring others and show them  how well you do what you do.

There is more treasure in books than in all the pirate’s loot on Treasure Island.

I have been up against tough competition all my life.I wouldn’t know how to get along without it.

No matter how your heart is grieving, if you keep on believing, the dreams that you    wish will come true.

The way to get started is to quit talking and begin doing.

The more you like yourself, the less you are like anyone else, which makes you unique.

Our greatest national resource is the minds of our children.

The past can hurt. But the way I see it, you can either run from it, or learn from it.

Disneyland will never be completed. It will continue to grow as long as there is imagination left in the world.

Laughter is America's most important export.

If you can dream it, you can do it.

Whatever we accomplish is due to the combined effort.

Nothing is impossible

You'll be a poorer person all your life if you don't know some of the great stories and great poems.

Get a good idea and stay with it. Dog it, and work at it until it's done right.

A lie keeps growing and growing until it's as plain as the nose on your face.

A man should never neglect his family for business.

Adults are only kids grown up.

The difference in winning & losing is most often, not quitting.

We keep moving forward, opening new doors, and doing new things, because we’re   curious and curiosity keeps leading us down new paths.

I never called my work an 'art' It's part of show business, the business of building  entertainment.

The era we are living in today is a dream of coming true.

We allow no geniuses around our Studio.

You can design and create, and build the most wonderful place in the world. But it takes people to make the dream a reality.

We are not trying to entertain the critics. I'll take my chances with the public.

Disneyland is a work of love. We didn't go into Disneyland just with the idea of   making money.

There's nothing funnier than the human animal.

A good story can take you on a fantastic journey.

THE SURVIVOR: Self-repairing plane technology with ‘human-like’ skin

0

Movies like The Terminator may have warned us not to create technology that can heal itself,but the folks at BAE Systems decided to press on regard less.The UK company has unveiled futuristic designs that could revolutionise the method and speed that planes are repaired by 2040. The aircraft’s body would be covered in ten soft thousands of micro sensors that detect wind speed,temperature and any damage sustained.The craft would be able to heal itself in mid air thanks to a grid of carbon nano tubes that hold a light weight adhesive fluid.This would be released to the damaged area and quickly harden–like blood forming as carbon a cut enabling the craft to continue its flight. This advanced use of materials would create an extremely hardy jet capable of entering the most dangerous of scenarios to complete vital missions,according to a BAE Systems spokesman.They are calling it The Survivor, and that’s not the only technology the company believes could be incorporated in military aircraft in the future.An other type of jet,known as The Transformer,would combine smaller sub-aircraft during travel and then split off.This would increase range and save fuel by reducing drag when they fly together. Despite edging use over closer to Sky net, this technology is hugely exciting for the aviation industry as smart planes would send maintenance costs and times plummeting,leaving us much more time to plan how to prevent them from rising up against us!
