By reading on screen, students gain not only reading comprehension skills but also computer confidence. Again, it is well to advise students of the advantages of distributed practice. They should be made aware that it is better to read two passages every day for five days than to read ten passages in one lab period. | 4. The word it in paragraph 1 refers to 6. As depth increases water X depth O pressure GD surface Beginning 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 about 1 F for every sixty feet under the Earth s surface and pressure increases with depth water that seeps down in cracks and fissures until it reaches very hot rocks in the Earth s interior becomes heated to a temperature of approximately 290 F. Water under pressure can remain liquid at temperatures above its normal boiling point but in a geyser the weight of the water nearer the surface exerts so much pressure on the deeper water that the water at the bottom of the geyser reaches much higher temperatures than does the water at the top of the geyser. As the deep water becomes hotter and consequently lighter it suddenly rises to the surface and shoots out of the surface in the form of steam and hot water. In turn the explosion agitates all the water in the geyser reservoir creating further explosions. Immediately afterward the water again flows into the underground reservoir heating begins and the process repeats itself. 5.

Why does the author mention New Zealand and Iceland in paragraph 4 C To compare areas of high volcanic activity GD To describe the Yellowstone National Park GD To provide examples of areas where geysers are located GD To name the two regions where all geysers are found Paragraph 4 is marked with an arrow - .
