Q: What are topographic maps that show water depths called? Read this paragraph and choose the correct option from the provided answers: Topographic maps that show water depths are called bathymetric maps . An example of one is pictured below ( Figure below ). Bathymetric maps are made of any water body, including lakes and oceans. On these maps, the contour lines represent depth below the surface. Therefore, high numbers are deeper depths and low numbers are shallow depths. Choices: - solenoid maps - morainic maps - Water Table maps - bathymetric maps A:
(Answer)
bathymetric maps

Q: Why do microwaves have a higher energy than radio waves? Read this paragraph and choose the correct option from the provided answers: Find the microwave in the Figure above . A microwave is an electromagnetic wave with a relatively long wavelength and low frequency. Microwaves are often classified as radio waves, but they have higher frequencies than other radio waves. With higher frequencies, they also have more energy. That's why microwaves are useful for heating food in microwave ovens. Microwaves have other important uses as well, including cell phone transmissions and radar. These uses are described below. You can learn more about microwaves and their uses in the video at this URL: http://www. youtube. com/watch?v=YgQQb1BVnu8 . Choices: - higher resonance - lower frequency - higher decibel - higher frequency A:
(Answer)
higher frequency

Q: What states that chemical reactions occur when atoms, ions, or molecules collide? Read this paragraph and choose the correct option from the provided answers: Collision theory states that chemical reactions occur when atoms, ions, or molecules collide. In other words, these species need to make contact with one another in order for a reaction to take place. Based on this concept, along with a couple of other key points, collision theory helps to explain why certain factors will influence the rate of a chemical reaction. Choices: - disturbance theory - reaction theory - elemental theory - collision theory A:
(Answer)
collision theory
