Q: Earthquake waves that travel trhough underground rocks in all directions are known as? Read this paragraph and choose the correct option from the provided answers: Another example of transverse waves occurs with earthquakes. The disturbance that causes an earthquake sends transverse waves through underground rocks in all directions from the disturbance. Earthquake waves that travel this way are called secondary, or S, waves. An S wave is illustrated in Figure below . Choices: - tertiary waves - primary waves - typical waves - secondary waves A:
secondary waves

Q: What term is used to describe potential energy due to an object's shape? Read this paragraph and choose the correct option from the provided answers: Irrigation is the single biggest use of water. Overhead irrigation wastes a lot of water. Drip irrigation ( Figure below ) wastes a lot less. Water pipes run over the surface of the ground. Tiny holes in the pipes are placed close to each plant. Water slowly drips out of the holes and soaks into the soil around the plants. Very little of the water evaporates or runs off the ground. Choices: - stimulated potential energy - flexible energy - kinetic energy - elastic potential energy A:
elastic potential energy

Q: Q: While matter is recycled, ecosystems need a constant input of what? Read this paragraph and choose the correct option from the provided answers: In all biomes, ecosystems need a constant input of energy. Matter, on the other hand, is constantly recycled in ecosystems. Choices: - heating - food - light - energy A:
A: energy

Question: Q: What kind of electricity can you generate with the energy found in flowing water? Read this paragraph and choose the correct option from the provided answers: The mechanical energy of rapidly flowing water can turn a turbine and generate electricity. Electricity produced in this way is called hydroelectric power. The water may flow over a waterfall or through a dam. You can see a picture of a dam in the Figure below . A drawback of dams is that they flood land upstream from the dam and reduce water flow downstream from the dam, and this can destroy ecosystems. At the following URL, you can learn more about hydroelectric power and see an animation of a hydroelectric power plant. Choices: - wind energy - electrical power - transient power - hydroelectric power A:
Answer: hydroelectric power

Q: What kind of muscle is responsible for making the human heart beat? Read this paragraph and choose the correct option from the provided answers: Muscle tissue consists of cells that can contract, or shorten. Examples include skeletal muscle, which is attached to bones and makes them move. Other types of muscle include cardiac muscle, which makes the heart beat, and smooth muscle, which is found in other internal organs. Choices: - deltoid - teres minor - respiratory muscle - cardiac muscle A:
**Answer**
cardiac muscle

Q: Ocean ridges formed by marine invertebrates living in warm shallow waters within the photic zone of the ocean are called what? Read this paragraph and choose the correct option from the provided answers: In which of the following regions would you expect to find photosynthetic organisms? a. The aphotic zone, the neritic zone, the oceanic zone, and the benthic realm. The photic zone, the intertidal zone, the neritic zone, and the oceanic zone. The photic zone, the abyssal zone, the neritic zone, and the oceanic zone. The pelagic realm, the aphotic zone, the neritic zone, and the oceanic zone. Coral Reefs Coral reefs are ocean ridges formed by marine invertebrates living in warm shallow waters within the photic zone of the ocean. They are found within 30 north and south of the equator. The Great Barrier Reef is a well-known reef system located several miles off the northeastern coast of Australia. Other coral reefs are fringing islands, which are directly adjacent to land, or atolls, which are circular reefs surrounding a former island that is now underwater. The coral-forming colonies of organisms (members of phylum Cnidaria) secrete a calcium carbonate skeleton. These calcium-rich skeletons slowly accumulate, thus forming the underwater reef (Figure 20.29). Corals found in shallower waters (at a depth of approximately 60 m or about 200 ft) have a mutualistic relationship with photosynthetic unicellular protists. The relationship provides corals with the majority of the nutrition and the energy they require. The waters in which these corals live are nutritionally poor and, without this mutualism, it would not be possible for large corals to grow because there are few planktonic organisms for them to feed on. Some corals living in deeper and colder water do not have a mutualistic relationship with protists; these corals must obtain their energy exclusively by feeding on plankton using stinging cells on their tentacles. Choices: - lagoon - trenches - break water - coral reefs A:
coral reefs
