Answer the following question given this paragraph: Fossils are preserved remains or traces of organisms that lived in the past. Most fossils form in sedimentary rock. Fossils can also be preserved in other ways. Fossilization is rare. It's very unlikely for any given organism to become a fossil. Q: What is the term for preserved remains or traces of organisms that lived in the past? A:

OPTIONS:
- deposits
- bones
- remains
- fossils

Answer: fossils

Problem: OPTIONS:
- combustion
- fermentation
- precipitation
- condensation
Q: Answer the following question given this paragraph: When air is very humid, it doesn't have to cool very much for water vapor in the air to start condensing. The temperature at which condensation occurs is called the dew point. The dew point varies depending on air temperature and moisture content. It is always less than or equal to the actual air temperature, but warmer air and moister air have dew points closer to the actual air temperature. That's why glasses of cold drinks "sweat" more on a hot, humid day than they do on a cool, dry day. For more details on the dew point, read the short article at this URL: http://www. kidsgeo. com/geography-for-kids/0108-dew-point. php. Q: Dew point is the temperature at which what occurs? A:
Answer: condensation

Problem:OPTIONS:
- refraction
- sonic wave
- reflection
- diffraction

Answer the following question given this paragraph: When a series of straight waves strike an impenetrable barrier, the waves stop at the barrier. However, the last particle of the medium at the back corner of the barrier will create circular waves from that point, called the point source. This can be seen in the image below. This phenomenon is called diffraction , and it occurs in liquid, sound, and light waves. While the waves become circular waves at the point source, they continue as straight waves where the barrier does not interfere with the waves. Q: What is the phenomenon in which light and sound waves become circular at the point source of a barrier? A:
****
A: diffraction

Answer the following question given this paragraph: Unlike amphibians, reptiles do not have a larval stage. Instead, newly hatched reptiles look like smaller versions of the adults. They are able to move about on their own, but they are vulnerable to predators. Even so, most reptile parents provide no care to their hatchlings. In fact, most reptiles don't even take care of their eggs. For example, female sea turtles lay their eggs on a sandy beach and then return to the ocean. The only exceptions are female crocodiles and alligators. They may defend their nest from predators and help the hatchlings reach the water. If the young remain in the area, the mother may continue to protect them for up to a year. Q: Unlike amphibians, reptiles do not have what stage? A:
OPTIONS:
- egg
- reproductive
- adult
- larval
larval

Answer the following question given this paragraph: Average speed is distance divided by time. Q: Average speed is equal to distance divided by what? A:
