Human body is made up of countless millions of cells. Food is needed to built up new cells and replace the worn out cells. However, the food that we take must be changed into substances that can be carried in the blood to the places where they are needed. This process is called digestion.

The first digestive process takes place in the mouth. The food we eat is broken up into small pieces by the action of teeth, mixed with saliva, a juice secreted by glands in the mouth. Saliva contains digestive juice which moisten the food, so it can be swallowed easily.

From the mouth, food passes through the esophagus (the food passage) into the stomach. Here, the food is mixed with the juices secreted by the cells in the stomach for several hours. Then the food enters the small intestine. All the time the muscular walls of the intestine are squeezing, mixing and moving the food onwards.

In a few hours, the food changes into acids. These are soon absorbed by the villi (microscopic branch projections from the intestine walls) and passed into the bloodstream.

Tsunami

Tsunami occurs when major fault under the ocean floor suddenly slips. The displaced rock pushes water above it like a giant paddle, producing powerful water waves at the ocean surface. The ocean waves spread out from the vicinity of the earthquake source and move across the ocean until they reach the coastline, where their height increases as they reach the continental shelf, the part of the earth crust that slopes, or rises, from the ocean floor up to the land.

A tsunami washes ashore with oftendisastrous effects such as severe flooding, loss of lives due to drowning and damage to property.

A tsunami is a very large sea wave that is generated by a disturbance along the ocean floor. This disturbance can be an earthquake, a landslide, or a volcanic eruption. A tsunami is undetectable far out in the ocean, but once it reaches shallow water, this fast traveling wave grows very large.

A natural disaster is a terrible accident, e.g. a great flood , a big fire, or an earthquake. It usually causes great suffering and loss of a large sum of money. The causalities are injured or died. Some people are homeless and need medical care.

Floods occur when the water of rivers, lakes, or stream overflow their banks and pour out into the surrounding land. Floods are caused by many different things. Often heavy rainstorms that last for a brief time can cause a flood. But not all heavy storms are followed by flooding. If the surrounding land is fl at and can absorb the water, no flooding will occur. If, however, the land is hard and rocky, heavy rain cannot be absorbed. Where the banks are low, a river may overflow and flood adjacent lowland.

In many parts of the world floods are caused by tropical storms called hurricanes or typhoons. They bring destructive winds of high speed, torrents of rain, and flooding. When a flood occurs, the destruction to the surrounding land can be severe. Whole villages and towns are sometimes swept away by water pouring swiftly over the land. Railroad tracks and buckles are uprooted from their beds. Highways are washed away.

When a building caught fire, the firemen pitched in to help battle the blaze. Before the pumps were invented, people formed bucket brigades to fight fires. Standing side by side, they formed a human chain from the fire to nearby well or river. They passed buckets of water from hand to hand to be poured on the flames.

The damage of fire did depend a great deal on where it happened. In the country or a small village, only a single house might burn down. But in crowded cities, fire often destroyed whole blocks and neighborhoods before being controlled.

What can possibly prevent rivers and lakes from overflowing?

How to Build Confidence?

Self-confidence is one of very important parts of humanity. Someone with self-confidence generally likes themselves and thinks positively about their future. A person who lacks of self-confidence, however, tend to be pessimistic and is less likely to feel that they can achieve their goals in life. The good news is that self-confidence is something you can build! So, how to build your self-confidence?

First of all, you need to identify your negative thoughts because your negative thoughts will always whisper like this: "I can't do that," "Many people say that I will not succeed", "no one understands my efforts." These pessimistic thoughts will hold you back from achieving high self-esteem and greater self-confidence.

After identifying your negative thoughts, you must turn them to positive thoughts. You must be more energized to prove that all of those pessimistic thoughts are incorrect. This may be started by having the positive affirmations to overcome those negative perspectives, such as "I am going to try it," "I can be successful if I work at it," or "people will listen to me." You must try to repeat these sentences over and over to burn your spirits.

Next, you should refuse negative thoughts to occur more often than positive thoughts. Your positive thoughts should be given more “brain space” than your negative thoughts. The more you counter your negative self-thinking with positivity, the better confidence you will have.

In conclusion, as your confidence grows day by day, you must eliminate reminders of your negativity that can make you feel bad about yourself again. Always boost all of your positivity to achieve your dreams! Negativities might be reminders from the past and let the positivity become the flashlight to lighten up your map of dreams. This will go a long way in building your self-confidence up.

Earthquake

An earthquake is a shaking of the ground caused by the sudden breaking and movement of large sections (tectonic plates) of the earth’s rocky outermost crust.

Earthquakes are usually caused when a rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing catch on each other. The rocks are still pushing against each other, but not moving. After a while, the rocks break because of all the pressure that’s built up. When the rocks break, the earthquake occurs.

The night sky that occur most frequently in high latitudes of both hemispheres. They are categorized specifically according to their location. Auroras in the Northern Hemisphere are called the northern lights (aurora borealis), and in the Southern Hemisphere, auroras are called the southern lights (aurora australis). Auroras are caused by the sun, but they are not sunlight. In addition to light, the sun also sends out electrically charged particles stream of electrons and protons, called the solar wind. This stream of particles travels from the sun towards the Earth at high speed.

The earth is surrounded by a magnetic field, consisting of north and south magnetic poles. These magnetic poles are not the same as the North and South poles. As the charged particles in the solar wind penetrate the earth’s magnetosphere and enter the lower Van Allen radiation belt, the earth magnetic field deflects it to the magnetic poles. Then they collide with gas molecules, mostly oxygen and nitrogen, in the atmosphere. These collisions cause them to emit visible light at various wavelengths, creating the colors of the aurora. Because the light of auroras is not strong enough, they are generally only visible at night.
