Volcanoes

Volcanoes normally originate in the mantle,the layer of earth about 80km below the crust.The heat inside this layer causes the rocks to melt and produce gas.The molten rocks,called magma,mix with the gas and become lighter than the surrounding rocks.Magma gradually rises upward making its way through the solid rocks above.Here it undergoes two types of action -intrusive and extrusive.In intrusive action,the magma solidifies within the faults and cracks and in its extrusive action,it moves upward.In its upward course,the magma forms a large magma chamber when it is just a few kilometers from the earth.There are solid rocks around magma chamber.The pressure of the solid rocks causes the magma to blast through the weaker parts crevices of the rock.Magma that finds its way through weaker rocks and spurts out is known as lava.

The volcanoes which have a constant emission of lava are known as active volcanoes.Those that spurt after a very long time span are dormant ones.The volcanoes which have erupted once and are not likely to emit lava ever again are known as extinct volcanoes.The crates of such volcanoes may fill with rainwater and eventually become a lake.

PACIFIC OCEAN

The pacific is some 166,241,00sq.km.in area.It is the largest of the oceans on Earth.It is more than twice the size of the Atlantic,the next largest ocean.Pacific occupies nearly half the Earth's surface.

It has an average depth of about 3,900m,but in its deepest regions,which are off the Philippine Islands,a depth of 36,198 feet has been recorded.
The pacific is dotted with some 20,000 volcani and coral islands are covered with lush vegetation.
The native island people of the Pacific fall into three main groups,Micronesian and polynesian.
These islanders had originally come from South East Asia.The European settlers arrived here in 1500s.
By the 1800s the islands had become colonies of various powerful countries overseas.Some of these islands have gained independence,yet some others are still under strong foreign control.

Tips to increase brains efficiency

1 Enough sleep
During sleep,brain cells remove toxic compounds dangerous to our brain,sleep for 7-8 hours every night at right time.

2 Avoid Stress
Prolonged stress destroys the brain.Avoid stress and stay calm,practice meditation so that it rewires  your brain. 

3 Hydration
The brain is very sensitive to dehydration,so keep yourself hydrated by drinking 3-4 liters of water every day at regular time intervals.

4 Avoid sugar
The abundance of fructose in diet slows down the brain and reduces its ability to learn,remember information and concentrate.

5 Art
Painting and drawing improves the work of the brain.

6 Reading
Reading books,articles and learning new languages not only enriches our knowledge,it also trains cognitive abilities of brain.It also activates areas that aren't used at other times.

7 Exercise
Exercise not only strengthens you physically,it helps in fighting stress and develops your brain.

Power of knowledge

Brain is powerful than muscle,knowledge is powerful than any physical act.Gaining knowledge is a key to success,hence feed your knowledge with right nutrition.A person with great knowledge and behavior can stay in the hearts of people.
