This Text is for question 9 to 10

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.

A geyser is the result of underground water under the combined conditions of high temperatures and increased pressure beneath the surface of the earth. Since temperature rises approximately 1 F for every sixty feet under the earth'S surface, and pressure increases with depth, the water that seeps down in crack and fissures until it reaches very hot rock in the earth interior becomes heated to temperature in excess of 290 F.

Because Of the greater pressure, the water shoots out of the surface in the form of steam and hot water. The result is a geyser. In order to function, then a geyser must have a source of heat, reservoir where water can be stored until the temperature rises to an unstable point, an opening through which the hot water and steam can escape, and underground channels for resupplying water after an eruption.

Favorable conditions for geyser exist in some regions of the world including New Zealand, Iceland, and the Yellowstone National Park area of the United States. The most famous geyser in the world is ld Faithfull in Yellow Park. Old Faithfull erupts almost every hour, rising to a height of 125 to 170 feet and expelling more than ten thousand gallons during each eruption.

Soal 11

How geyser is produced?

A. By the rise of temperature pressure functioning hot steam.
B. From a huge tension of heated water that coming out from the earth crack.
C. From the heated temperature in earth cracK that absorbing water.
D. By the hot water and temperature of hot rock that occurs on earth surface.

Soal 12

Steam and hot water shoot out of the surface because of ...

A. hot rock and water
B. temperature and pressure
C. greater pressure
D. high temperature and increased pressure
