Answer the following question given this paragraph: Underground water can be heated by magma. The hot water moves through cracks below Earth's surface. Hot water can hold more dissolved particles than cold water. The hot, salty solution has chemical reactions with the rocks around it. The water picks up more dissolved particles. As it flows through open spaces in rocks, the water deposits solid minerals. When a mineral fills cracks in rocks, the deposits are called "veins. " Figure below shows a white quartz vein. When the minerals are deposited in open spaces, large crystals grow. These rocks are called geodes. Figure below shows a "geode" that was formed when amethyst crystals grew in an open space in a rock. Q: What are the mineral deposits that fill in underground cracks called? Choices: - cores - currents - motherlode - veins A:
(Answer)
veins
Ques: Answer the following question given this paragraph: Two planets are on a collision course, heading directly towards each other at 0.250c . A spaceship sent from one planet approaches the second at 0.750c as seen by the second planet. What is the velocity of the ship relative to the first planet? 28. When a missile is shot from one spaceship towards another, it leaves the first at 0.950c and approaches the other at ships?. Q: Spinal cord injuries are notoriously difficult to treat because spinal nerves do not do what? Choices: - cover - cartilage - moisture - regenerate A:

Answer the following question given this paragraph: Your feet feel cold as you walk barefoot across the living room carpet in your cold house and then step onto the kitchen tile floor. This result is intriguing, since the carpet and tile floor are both at the same temperature. The different sensation you feel is explained by the different rates of heat transfer: the heat loss during the same time interval is greater for skin in contact with the tiles than with the carpet, so the temperature drop is greater on the tiles. Some materials conduct thermal energy faster than others. In general, good conductors of electricity (metals like copper, aluminum, gold, and silver) are also good heat conductors, whereas insulators of electricity (wood, plastic, and rubber) are poor. Q: There is a positive correlation between the ability to conduct thermal energy and what other energy, as exemplified by metals? Choices: - nuclear - gravitational - elastic - electricity A:
(A).
electricity
