Q: Answer the following question given this paragraph: Elastic rebound theory. Stresses build on both sides of a fault. The rocks deform plastically as seen in Time 2. When the stresses become too great, the rocks return to their original shape. To do this, the rocks move, as seen in Time 3. This movement releases energy, creating an earthquake. Q: What theory says stresses build on both sides of a fault? Choices: - Geiger theory - seismic load theory - Big Bang theory - elastic rebound theory A:
A: elastic rebound theory

Q: Answer the following question given this paragraph: Eventually plants evolved. Plants produce oxygen as a product of photosynthesis. Oxygen spread around the planet about 2.5 billion years ago. Many organisms died off because they could not handle the oxygen. But this development was extremely important for other life. Animals need oxygen to breathe. If photosynthesis had not evolved there would be no animals. Q: Because it produces oxygen, what plant process was necessary for the evolution of animals? Choices: - germination - death - reproduction - photosynthesis A:
A: photosynthesis

Q: Answer the following question given this paragraph: A solution is another name for a homogeneous mixture. http://catalog. flatworldknowledge. com/bookhub/reader/2547 - gob-ch01defined a mixture as a material composed of two or more substances. In a solution, the combination is so intimate that the different substances cannot be differentiated by sight, even with a microscope. Compare, for example, a mixture of salt and pepper and another mixture consisting of salt and water. In the first mixture, we can readily see individual grains of salt and the flecks of pepper. A mixture of salt and pepper is not a solution. However, in the second mixture, no matter how carefully we look, we cannot see two different substances. Salt dissolved in water is a solution.
