A tsunami occurs when a 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's crust that slopes, or rises, from the ocean floor up to the land.

A tsunami washes ashore with often disastrous 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 happens because ...

• The displaced rock pushes water above it.
  
  

• A significant fault under the ocean floor slips suddenly.

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

• The waves move across the ocean until they reach the beach.

What are the impacts of tsunami?

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

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

• A tsunami is a very large sea wave that is not generated by a disturbance along the ocean floor.

• A tsunami is detectable far out in the ocean.

We understand from the text that tsunami ...

• cause the movemnet of the earth

• Forms a new shape of the coastline

• Makes unfortunate events

• Rises a new coastal land

"... producing powerful water waves at the ocean surface." The synonym of the underlined word is ...

• Fast

• Deep

• Quick

• Strong

Recycling is the collection, processing, and reuse of materials that would otherwise be thrown away. Materials ranging from precious metals to broken glass, from old newspapers to plastic spoons, can be recycled. The recycling process reclaims the original material and uses it in new products.

In general, using recycled materials to make new products costs less and requires less energy than using new materials. Recycling can also reduce pollution, either by reducing the demand for high-pollution alternatives or minimizing the pollution produced during the manufacturing process.

Paper products that can be recycled include cardboard containers, wrapping paper, and office paper. The most commonly recycled paper product is newsprint. In newspaper recycling, old newspapers are collected and searched for contaminants such as plastic bags and aluminum foil. The paper goes to a processing plant where it is mixed with hot water and turned into pulp in a machine that works much like a big kitchen blender.

The pulp is screened and filtered to remove smaller contaminants. The pulp then goes to a large vat where the ink separates from the paper fibers and floats to the surface. The ink is skimmed off, dried, and reused as ink or burned as boiler fuel. The cleaned pulp is mixed with new wood fibers to be made into paper again.

Experts estimate the average office worker generates about 5 kg of wastepaper per month. Every ton of paper that is recycled saves about 1.4 cu m (about 50 cu ft) of landfill space. One ton of recycled paper saves 17 pulpwood trees (trees used to produce paper).

The following things can be recycled except ...

• precious metals

• broken glass

• old newspapers

• fresh vegetables and fruits

Which of the following is not the benefit of recycling?

• It costs a lot of money for the process of recycling.
  

• It costs less to make new products.
  

• It requires less energy.

• It reduces the demand for high-pollution alternatives.

We can make use of the ink after being separated from the paper fibers by doing the followings, except ...

• Skim it off

• Dry it

• Reuse as ink

• Mix it with the pulp

All planes need air to presure under their wings to stay up in the air. As they move forward. The higher air pressure underneath their wings pushes them upward and gives them lift. The smooth, streamlined shape of the plane allows the air to flows easily over its surface. This helps to reduce the drag caused by the air pushing against the plane and allows it to move rapidly through the air. Planes move forward using engines. This movement is called thrust. Moving forward Keeps a stream of moving air passing over the wings. If the engines fail, theplanes will begin to descend very quickly. The air above the wing moves faster, so it is at a lower pressure than the air under the wing. The air under the wing moves more slowly and is slightly squashed, so it is at a higher pressure than the air above the wing.

What does the text explain?

• How the wings of a plane work

• How the plane moves forward

• How the plane is made

• The engine of a plane
