Q: The energy in sunlight is also known as what kind of energy? Read this paragraph and choose the correct option from the provided answers: The energy in sunlight, or solar energy, can be used to heat homes. It can also be used to produce electricity in solar cells. However, solar energy may not be practical in areas that are often cloudy. Choices: - kinetic energy - potential energy - geothermal energy - solar energy A:
**Answer**
solar energy

Q: Biomass, solar, wind, water, and geothermal power are examples of what kinds of energy resources? Read this paragraph and choose the correct option from the provided answers: Renewable energy resources include solar, water, wind, biomass, and geothermal power. These resources are usually replaced at the same rate that we use them. Scientists know that the Sun will continue to shine for billions of years. So we can use the solar energy without it ever running out. Water flows from high places to lower ones. Wind blows from areas of high pressure to areas of low pressure. We can use the flow of wind and water to generate power. We can count on wind and water to continue to flow! Burning wood ( Figure below ), is an example of biomass energy. Changing grains into biofuels is biomass energy. Biomass is renewable because we can plant new trees or crops to replace the ones we use. Geothermal energy uses water that was heated by hot rocks. There are always more hot rocks available to heat more water. Choices: - mechanical - electrical - fossil fuel - renewable A:
**Answer**
renewable

*Question*
Q: Recrystallization is a process that can remove what, which result when compounds are synthesized? Read this paragraph and choose the correct option from the provided answers: When compounds are synthesized, they often have contaminating materials mixed in with them. The process of recrystallization can be used to remove these impurities. The crystals are dissolved in a hot solvent, forming a solution. When the solvent is cooled the compound is no longer as soluble and will precipitate out of solution, leaving other materials still dissolved. Choices: - chemicals - substances - minerals - contaminants A:
**Answer**
contaminants
