Answer the following question given this paragraph: The transfer of electrons from the van de Graaff generator to the man is an example of conduction. Conduction occurs when there is direct contact between materials that differ in their ability to give up or accept electrons. A van de Graff generator produces a negative charge on its dome, so it tends to give up electrons. Human hands are positively charged, so they tend to accept electrons. Therefore, electrons flow from the dome to the man's hand when they are in contact. Q: A van de graff generator produces what type of charge on its dome, causing the tendency to give up electrons? A:
OPTIONS:
- positive charge
- similar charge
- no charge
- negative charge

Answer: negative charge

Question: Answer the following question given this paragraph: Every chemical reaction occurs with a concurrent change in energy. Q: Every chemical reaction occurs with a concurrent change in what? A:

input with options: Answer the following question given this paragraph: The weathering of rocks and minerals can be mechanical or chemical. Mechanical weathering changes the size of a mineral or rock. Mechanical weathering does not change the chemical composition of that material. Chemical weathering changes the composition of a mineral or rock. Different types of weathering can alter the same material. Soil forms on top of rock. The type of soil that forms depends on the environment of the region. For example, warm and wet climates form different soils than cold and dry climates. A profile through the soil shows different horizons. Topsoil is the most important layer for crops. Water, ice, wind, and gravity create or modify landforms on Earth's surface. These agents can erode or deposit features that indicate their presence. Erosion by water and ice lowered and rounded the Appalachians. These old mountains no longer look like the Himalaya. Someday the Himalaya may look like the Appalachians do now. Q: What kind of weathering changes the size of a mineral or rock but does not change its chemical composition? A:
OPTIONS:
- molecular weathering
- chemical reaction
- radiation
- mechanical weathering
output: mechanical weathering

Q: Answer the following question given this paragraph: Every plant and animal depends on its traits to survive. Survival may include getting food, building homes, and attracting mates. Traits that allow a plant, animal, or other organism to survive and reproduce in its environment are called adaptations .

OPTIONS:
- additions
- advantages
- settings
- adaptations

A: adaptations
