Q: What kind of surface would cause diffusion when light is reflected off of it? Read this paragraph and choose the correct option from the provided answers: The angle of reflection equals the angle of incidence. A mirror has a smooth surface and reflects light at specific angles. Light is diffused when it reflects from a rough surface. Mirror images can be photographed and videotaped by instruments. Choices: - hot surfaces - cold surfaces - smooth surfaces - rough surfaces A:
rough surfaces

A: evolution

Question: Q: The reaction of calcium oxide with carbon dioxide forms what? Read this paragraph and choose the correct option from the provided answers: The way in which a reaction is written influences the value of the enthalpy change for the reaction. Many reactions are reversible, meaning that the product(s) of the reaction are capable of combining and reforming the reactant(s). If a reaction is written in the reverse direction, the sign of the changes. For example, we can write an equation for the reaction of calcium oxide with carbon dioxide to form calcium carbonate. Choices: - nitrogen carbonate - carbon monoxide - nitrogen - calcium carbonate A:
Answer: calcium carbonate

Q: If pressure is exerted on the rock from one direction, the rock forms layers. this is called what? Read this paragraph and choose the correct option from the provided answers: During metamorphism, a rock may change chemically. Ions move in or out of a mineral. This creates a different mineral. The new minerals that form during metamorphism are more stable in the new environment. Extreme pressure may lead to physical changes. If pressure is exerted on the rock from one direction, the rock forms layers. This is foliation . If pressure is exerted from all directions, the rock usually does not show foliation. Choices: - protonation - stratification - sedimentation - foliation A:
**Answer**
foliation

Q: What is formed when the ceiling of an underground cave collapses? Read this paragraph and choose the correct option from the provided answers: As erosion by groundwater continues, the ceiling of a cave may collapse. The rock and soil above it sink into the ground. This forms a sinkhole on the surface. You can see an example of a sinkhole in Figure below . Some sinkholes are big enough to swallow vehicles and buildings. Choices: - hill - groundwater - mountain - sinkhole A:
(Answer)
sinkhole
