Ques:Answer the following question given this paragraph: The figure above also shows how the size of waves is measured ( Figure above ). The highest point of a wave is the crest . The lowest point is the trough . The vertical distance between a crest and a trough is the wave height . Wave height is also called amplitude . The horizontal distance between two crests is the wavelength . Both amplitude and wavelength are measures of wave size. Q: To figure out the height of a wave you measure the distance between the crest and what? Choices: - drift - core - crater - trough A:

Ans:trough

Ques:Answer the following question given this paragraph: At divergent plate boundaries hot mantle rock rises into the space where the plates are moving apart. As the hot mantle rock rises, it goes from higher to lower pressure. This is because there is no longer the weight of all the rock above it. Lower pressure lowers the melting temperature of the rock (2 in the previous section). This is why there is volcanism at divergent plate boundaries. Lava erupts through long cracks in the ground, or fissures. Q: Lava erupts through long cracks in the ground, also called what? Choices: - ridges - crevasses - faults - fissures A:

Ans:fissures
