Context: Its been over a year since the Alaskan town of Barrow's population was decimated by a gang of vampires during its annual month long sunset. Riddled with grief over the death of her husband, bound by nightmares and void of all emotions beyond hate and sorrow, Stella (Kiele Sanchez) has spent the past months traveling the world, trying to convince others that vampires exist in this world.Constantly feeling as though she is being hunted, Stella is well aware the impending threat on her life, the death of her husband Eben having taken from her her ability to feel emotions, leaving her feeling cold and empty inside. Following instructions from a mysterious man named Dane, she eventually ends up in Los Angeles.One night, while giving a lecture to an audience of people with whom she hopes to convince that vampires exist and aware that they attend when she speaks, she activates overhead ultraviolet lamps that incinerate several of the vampires in the audience before the humans. She is quickly arrested and harassed by a man named FBI Agent Norris whom she quickly learns that he is a 'familiar' (bug-eater) one of the many thousands of human followers of the vampires all over the world, placed to keep their activities covered up. After they release her from custody with a warning to keep quiet about the existence of vampires, she returns to her hotel room to find three people waiting for her; Paul (Rhys Coiro), Amber (Diora Baird) and Todd (Harold Perrineau) who had been sent by Dane to collect her in order to hunt down the vampire queen Lilith, whom they are convinced once out of the way, the vampires will fall into more-or-less form of dormancy as she is responsible for their every move and for keeping them hidden, when Stella asks if she is responsible for the incident at Barrow and is notified that she was. She is taken to meet Dane (Ben Cotton) and is shocked to discover that he too is a vampire, though due to a superficially inflicted wound he has maintained a grasp of humanity, only drinking blood from packaged hospital stocks he keeps.At first hesitant to join in on a plan to attack a vampire nest, Paul eventually convinces Stella to join them, telling her of his daughter being killed by one and his accusations of a vampire killing her resulting in a divorce with his wife.The following day, the four of them find their way to a vampire's nest and they are ambushed by a group of them. In the attempt to flee, Todd is bitten and turns after they lock themselves in a cellar room. When Paul hesitates, Stella manages to kill him by smashing in his head with a cinder block. They decide to wait for night when the vampires go out to feed in order to make their escape.After night falls, Dane comes and frees them, on their way out they capture a vampire. Taking him back to their base of operations, Dane interrogates the non-English speaking animalistic vamp with ultraviolet lamps, eventually following him back to another nest. They invade the nest and rescue a human they were using as a feeding station and with her memories of Lilith's lair aboard one of the ships on the bay they are able to plan an attack on her directly.At Dane's place, Stella and Paul get intimate and have sex. Meanwhile, Lilith (Mia Kirshner) decides that Agent Norris should prove his worth to become a vampire (in order to cure throat or lung cancer he has been suffering from) and he bites the neck of a captive girl, named Stacey (Katharine Isabelle), drinking her blood until dead. Afterward she turns him to hunt Stella and the others.Dane is killed when Norris arrives, and the others flee with the survivor from the nest, they travel to a boat yard and Jennifer points out the boat that they are set to sail to Alaska in for another 30 day feeding period. They tell Jennifer to leave and the three of them stowaway on the ship and discover that vampires can be resurrected after death if their corpses are fed human blood. They eventually confront the human captain who says

Context: All volcanoes share the same basic features. First, mantle rock melts. The molten rock collects in magma chambers that can be 160 kilometers (100 miles) beneath the surface. As the rock heats, it expands. The hot rock is less dense than the surrounding rock. The magma rises toward the surface through cracks in the crust. A volcanic eruption occurs when the magma reaches the surface. Lava can reach the surface gently or explosively. Eruptions can be explosive or non-explosive. Only rarely do gentle and explosive eruptions happen in the same volcano. An explosive eruption produces huge clouds of volcanic ash. Chunks of the volcano fly high into the atmosphere. Explosive eruptions can be 10,000 times as powerful as an atomic bomb (Figure 8.6). Hot magma beneath the surface mixes with water. This forms gases. The gas pressure grows until it must be released. The volcano erupts in an enormous explosion. Ash and particles shoot many kilometers into the sky. The material may form a mushroom cloud, just like a nuclear explosion. Hot fragments of rock, called pyroclasts, fly up into the air at very high speeds. The pyroclasts cool in the atmosphere. Some ash may stay in the atmosphere for years. The ash may block out sunlight. This changes weather patterns and affects the temperature of the Earth. For a year or two after a large eruption, sunsets may be especially beautiful worldwide. Volcanic gases can form poisonous, invisible clouds. The poisonous gases may be toxic close to the eruption. The gases may cause environmental problems like acid rain and ozone destruction. Mt St. Helens was not a very large eruption for the Cascades. Mt. Mazama blew itself apart in an eruption about 42 times more powerful than Mount St. Helens in 1980. Today all that remains of that huge stratovolcano is Crater Lake (Figure 8.18). Some volcanic eruptions are non-explosive (Figure 8.7). This happens when there is little or no gas. The lava is thin, fluid and runny. It flows over the ground like a river. People generally have a lot of warning before a lava flow like this reaches them, so non-explosive eruptions are much less deadly. They may still be destructive to property, though. Even when we know that a lava flow is approaching, there are few ways of stopping it! Great volcanic explosions and glowing red rivers of lava are fascinating. All igneous rock comes from magma or lava. Remember that magma is molten rock that is below Earths surface. Lava is molten rock at Earths surface. Magma forms deep beneath the Earths surface. Rock melts below the surface under tremendous pressure and high temperatures. Molten rock flows like taffy or hot wax. Most magmas are formed at temperatures between 600o C and 1300o C (Figure 8.8). Magma collects in magma chambers beneath Earths surface. Magma chambers are located where the heat and pressure are great enough to melt rock. These locations are at divergent or convergent plate boundaries or at hotpots. The chemistry of a magma determines the type of igneous rock it forms. The chemistry also determines how the magma moves. Thicker magmas tend to stay below the surface or erupt explosively. When magma is fluid and runny, it often reaches the surface by flowing out in rivers of lava. The way lava flows depends on what it is made of. Thick lava doesnt flow easily. It may block the vent of a volcano. If the lava traps a lot of gas, the pressure builds up. After the pressure becomes greater and greater, the volcano finally explodes. Ash and pyroclasts shoot up into the air. Pumice, with small holes in solid rock, shows where gas bubbles were when the rock was still molten. Fluid lava flows down mountainsides. The rock that the flow becomes depends on which type of lava it is and where it cools. The three types of flows are aa, pahoehoe, and pillow lava. Aa Lava Aa lava is the thickest of the non-explosive lavas. Aa forms a thick and brittle crust, which is torn into rough, rubbly pieces. The solidified surface is angular, jagged and sharp. Aa can
