Answer the following question given this paragraph: Chemical reactions are described using chemical equations. Q: How do we describe chemical reactions? Choices: - balanced reactions - equilibrium - atomic numbers - chemical equations A:
chemical equations
Answer the following question given this paragraph: Scientists search for answers to questions and solutions to problems by using a procedure called the scientific method. This procedure consists of makingobservations, formulating hypotheses, and designing experiments, which in turn lead to additional observations, hypotheses, and experiments in repeated cycles (Figure 1.4 "The Scientific Method"). Q: Scientists search for answers to questions and solutions to problems by using a procedure called this? Choices: - measured method - continued method - careful method - scientific method A:
scientific method
Q: Answer the following question given this paragraph: Near-Earth asteroids have orbits that cross Earth's orbit. This means that they can collide with Earth. There are over 4,500 known near-Earth asteroids. Small asteroids do sometimes collide with Earth. An asteroid about 510 m in diameter hits about once per year. Five hundred to a thousand of the known near-Earth asteroids are much bigger. They are over 1 kilometer in diameter. When large asteroids hit Earth in the past, many organisms died. At times, many species became extinct in a mass extinction. Astronomers keep looking for near-Earth asteroids. They hope to predict a possible collision early so they can to try to stop it. Q: Near-earth asteroids cross paths with earth, meaning they could collide; what are the paths called? Choices: - trajectory - curves - galaxies - orbits A:
A: orbits
Question: Answer the following question given this paragraph: Some springs have water that contains minerals. Groundwater dissolves minerals out of the rock as it seeps through the pores. The water in some springs is hot because it is heated by hot magma. Many hot springs are also mineral springs. That's because hot water can dissolve more minerals than cold water. Q: The water in some springs are hot because they're heated by what? Choices: - gravity - the sun - fires - hot magma A:
Answer: hot magma

Answer the following question given this paragraph: A soil is a residual soil when it forms in place. Only about one third of the soils in the United States form this way. The material comes from the underlying bedrock. Residual soils form over many years since it takes a long time for solid rock to become soil. First, cracks break up the bedrock. This may happen due to ice wedging. Weathering breaks up the rock even more. Then plants, such as lichens or grasses, become established. They cause further weathering. As more time passes and more layers of material weather, the soil develops. Q: Soil that forms in place over a very long period is called what? Choices: - leakage soil - antique soil - resultant soil - residual soil A:
**Answer**
residual soil
Q: Answer the following question given this paragraph: Deciduous trees are common in humid continental climates. Conifer forests grow in the subarctic. Q: In what type of climate might one find deciduous trees? Choices: - thick continental - Dry Continental - moist continental - humid continental A:
A: humid continental
