Q: Answer the following question given this paragraph: Q: An irreversible increase in size is known as? A:

OPTIONS:
- mass
- strength
- volume
- growth

A: growth

input: OPTIONS:
- Convection Zone
- Chromosphere
- Photosphere
- the core Now, answer this question: Answer the following question given this paragraph: Because the Sun is not solid, it does not have a defined outer boundary. It does, however, have a definite internal structure with identifiable layers ( Figure below ). Since the layers are not solid, the boundaries are fuzzy and indistinct. From inward to outward, the layers are: the core, the radiative zone, and the convection zone. Q: What is the innermost layer of the sun called? A:
A:
output: the core

Answer the following question given this paragraph: Scientists are searching for ways to create controlled nuclear fusion reactions on Earth. Their goal is develop nuclear fusion power plants, where the energy from fusion of hydrogen nuclei can be converted to electricity. How this might work is shown in Figure below . Q: Scientists goal is develop nuclear fusion power plants, where the energy from fusion of hydrogen nuclei can be converted to what? A:

OPTIONS:
- oil
- gasoline
- wind
- electricity

Answer: electricity

Problem: OPTIONS:
- troposphere
- magnetosphere
- hydrosphere
- asthenosphere
Q: Answer the following question given this paragraph: Below the lithosphere is the asthenosphere . The asthenosphere is also in the upper mantle. This layer is solid, but it can flow and bend. A solid that can flow is like silly putty. Q: What layer is below the lithosphere and in the upper mantle? A:
Answer: asthenosphere

Problem:OPTIONS:
- calcification
- migration
- evaporation
- erosion

Answer the following question given this paragraph: Mountain streams may erode waterfalls. A waterfall forms where a stream flows from an area of harder to softer rock ( Figure below ). The water erodes the softer rock faster than the harder rock. This causes the stream bed to drop down, like a step. This creates a waterfall. As erosion continues, the waterfall gradually moves upstream. Q: What process is involved in the formation of a waterfall, when a stream flows from an area of harder to softer rock? A:
****
A: erosion

Problem:OPTIONS:
- hill
- groundwater
- mountain
- sinkhole

Answer the following question given this paragraph: 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. Q: What is formed when the ceiling of an underground cave collapses? A:
****
A:
sinkhole
