Answer the following question given this paragraph: Waves that travel through mattersuch as the fabric of a flagare called mechanical waves. The matter they travel through is called the medium. When the energy of a wave passes through the medium, particles of the medium move. The more energy the wave has, the farther the particles of the medium move. The distance the particles move is measured by the wave's amplitude. Q: What term describes waves that travel through matter? Choices: - replaced waves - water waves - heat waves - mechanical waves A:
mechanical waves

Answer the following question given this paragraph: Fission is the process in which an atomic nucleus breaks apart into two less massive nuclei. Energy is released in the process in many forms, heat, gamma rays and the kinetic energy of neutrons. If these neutrons collide with nuclei and induce more fission, then a runaway chain reaction can take place. Fission is responsible for nuclear energy and atom-bomb explosions: the fission of uranium acts as a heat source for the Earth's molten interior. Q: The process where an atomic nucleus breaks apart into two less massive nuclei is known as ______. Choices: - diffusion - fusion - collision - fission A:
fission

Answer the following question given this paragraph: When two plates of continental crust collide, the material pushes upward. This forms a high mountain range. The remnants of subducted oceanic crust remain beneath the continental convergence zone. Q: When two plates of continental crust collide, the material pushes upward and forms what? Choices: - fault lines - valleys - low mountain range - high mountain range A:
high mountain range
