Question: Answer the following question given this paragraph: Surface mining is used to obtain mineral ores that are near the surface. Blasting breaks up the soil and rocks that contain the ore. Enormous trucks haul the broken rocks to locations where the ores can be removed. Surface mining includes open-pit mining, quarrying, and strip mining. Q: What type pf mining is used to obtain mineral ores that are near the surface? Choices: - multi-layered mining - function mining - core mining - surface mining A:
Answer: surface mining

Question: Answer the following question given this paragraph: Echo sounders were used to search for enemy submarines during World War II. The depths they recorded allowed scientists to piece together bathymetric maps of the seafloor. Multi-beam sounders work on research vessels today. Q: What do waves deposit in relatively quiet areas along a shore? Choices: - fish - mud - snow - sand A:
Answer: sand

Question: Answer the following question given this paragraph: Resistors in Series: All resistors are connected end to end. There is only one river, so they all receive the same current. But since there is a voltage drop across each resistor, they may all have different voltages across them the sum of the voltage drops will equal the total voltage of the circuit. The more resistors in series the more rocks in the river, so the less current that flows. Q: Resistors connected end to end are said to be in what? Choices: - parallel - groups - lines - series A:
Answer:
series
