EXPLANATION TEXT SMA 5

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.

• How can we swallow the food easily?

• The food changes into acids absorbed by the villi.

• The food must be digested first through the process.

• The food is directly swallowed through esophagus into the stomach.

• The food is mixed with the juices secreted by the cells in the stomach.

• The food we take must be changed into substances carried in the blood to the places.

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.

Tsunami happened because of.....

• The displaced rock pushes water above it

• A major fault under the ocean floor slips suddenly

• The ocean waves spread out from the vicinity of the source

• The waves moves across the ocean until they reach the beach

• A tsunami is undetectable far out in the ocean

What are the impacts of tsunami?

• The part of the Earth’s crust that slopes, or rises, from the ocean floor down to the land

• A tsunami washes ashore with often disastrous effects such as flooding and loss of lives

• A tsunami is a very large sea wave which is not generated by a disturbance a long the ocean floor

• A tsunami is detectable far out in the ocean

• Once tsunami reaches shallow water, the wave never grows very large

We understand from the text that tsunami ....

• Causes the movement of earth

• Forms a new shape of coastline

• Makes unfortunate event

• Rises a new coastal land

• Displaces rocks to land

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.

What does the text mainly explain?

• the meaning of earthquake

• the types of earthquake

• the cause of earthquake

• the effects of earthquake

• the place where earthquake happens

• the rock underground suddenly breaks

• the ground is moved
