Q: Answer the following question given this paragraph: Reflected waves have the same speed and frequency as the original waves before they were reflected. However, the direction of the reflected waves is different. When waves strike an obstacle head on, the reflected waves bounce straight back in the direction they came from. When waves strike an obstacle at any other angle, they bounce back at the same angle but in a different direction. This is illustrated in the Figure below . In this diagram, waves strike a wall at an angle, called the angle of incidence. The waves are reflected at the same angle, called the angle of reflection, but in a different direction. Notice that both angles are measured relative to a line that is perpendicular to the wall. Q: When waves are reflected at the same angle, what is it called? A:

OPTIONS:
- field of view
- refraction
- phenomenon of reflection
- angle of reflection

A: angle of reflection

input: OPTIONS:
- no effect
- more moderate
- it drops
- it increases Now, answer this question: Answer the following question given this paragraph: The rise in greenhouse gases due to human actions is too much of a good thing. It increases the greenhouse effect and causes Earth's average temperature to rise. Rising global temperatures, in turn, are melting polar ice caps and glaciers. Figure below shows how much smaller the Arctic ice cap was in 2012 than it was in 1984. With more liquid water on Earth's surface, sea levels are rising. Q: The rise in greenhouse gases has what effect on the temperature of earth? A:
A:
output: it increases

Answer the following question given this paragraph: Regional metamorphism occurs over a large area when a rock is buried or compressed. Q: What occurs over a large area when a rock is buried or compressed? A:

OPTIONS:
- metamorphic diffusion
- cavern system
- landslide
- regional metamorphism

Answer: regional metamorphism

Problem: OPTIONS:
- melt
- fuse
- dissolve
- evaporate
Q: Answer the following question given this paragraph: The presence of solute particles blocks some of the ability for liquid particles to evaporate. Thus, solutions of solid solutes typically have a lower vapor pressure than the pure solvent. Q: The presence of solute particles blocks some of the ability for liquid particles to do what? A:
Answer: evaporate
