question:
Context: Extrusive igneous rocks cool at the surface. Volcanoes are one type of feature that forms from extrusive rocks. Several other interesting landforms are also extrusive features. Intrusive igneous rocks cool below the surface. These rocks do not always remain hidden. Rocks that formed in the crust are exposed when the rock and sediment that covers them is eroded away. When lava is thick, it flows slowly. If thick lava makes it to the surface, it cannot flow far from the vent. It often stays right in the middle of a crater at the top of a volcano. Here the lava creates a large, round lava dome (Figure A lava plateau is made of a large amount of fluid lava. The lava flows over a large area and cools. This creates a large, flat surface of igneous rock. Lava plateaus may be huge. The Columbia Plateau covers over 161,000 square kilometers (63,000 square miles). It makes up parts of the states of Washington, Oregon, and Idaho. Thin, fluid lava created the rock that makes up the entire ocean floor. This is from multiple eruptions from vents at the mid-ocean ridge. While not exactly a lava plateau, its interesting to think about so much lava! New land is created in volcanic eruptions. The Hawaiian Islands are shield volcanoes. These volcanoes formed from fluid lava (Figure 8.21). The island grows as lava is added on the coast. New land may also emerge from lava that erupts from beneath the water. This is one way that new land is created. Magma that cools underground forms intrusions (Figure 8.22). Intrusions become land formations if they are exposed at the surface by erosion. Water works its way through porous rocks or soil. Sometimes this water is heated by nearby magma. If the water makes its way to the surface, it forms a hot spring or a geyser. When hot water gently rises to the surface, it creates a hot spring. A hot spring forms where a crack in the Earth allows water to reach the surface after being heated underground. Many hot springs are used by people as natural hot tubs. Some people believe that hot springs can cure illnesses. Hot springs are found all over the world, even in Antarctica! Geysers are also created by water that is heated beneath the Earths surface. The water may become superheated by magma. It becomes trapped in a narrow passageway. The heat and pressure build as more water is added. When the pressure is too much, the superheated water bursts out onto the surface. This is a geyser. There are only a few areas in the world where the conditions are right for the formation of geysers. Only about 1,000 geysers exist worldwide. About half of them are in the United States. The most famous geyser is Old Faithful at Yellowstone National Park (Figure 8.23). It is rare for a geyser to erupt so regularly, which is why Old Faithful is famous. 
 Question: hot water under pressure that forcefully erupts out of the surface
answer:
geyser


question:
Context: The Raiders traveled across the bay to Monster Park in San Francisco to take on the 49ers. The 49ers got on the board first with an Alex Smith to Arnaz Battle touchdown pass midway through the first quarter. The Raiders responded with a 33-yard field goal by Sebastian Janikowski. Janikowski then converted a 36 yarder early in the second quarter. Randy Moss scored his 100th career touchdown reception on a 22-yard pass from Andrew Walter, as the Raiders went into halftime with a 13-7 lead. The 49ers then went on to score 24 unanswered points in the second half, as Smith connected on touchdown passes with Battle once again, and Maurice Hicks in the third quarter. Joe Nedney converted a chip shot 19-yard field goal early in the fourth quarter. On the next Raiders play from scrimmage, Melvin Oliver recovered a fumble for a touchdown, as Walter tried to lateral a pass to LaMont Jordan, who let it hit the ground, and assumed it was an incomplete pass. Marques Tuiasosopo hit Courtney Anderson with a touchdown pass late in the game, but it was too little too late. Nedney completed the scoring with a 39-yard field goal. 
 Question: Who scored first in the first quarter?
answer:
the 49ers
