Answer the following question given this paragraph: Landslides often occur on steep slopes in dry or semi-arid climates. The California coastline, with its steep cliffs and years of drought punctuated by seasons of abundant rainfall, is prone to landslides. Wet soil becomes slippery and heavy. Earthquakes often trigger landslides. The shaking ground causes soil and rocks to break loose and start sliding. Q: What often occurs on steep slopes in dry climates? Choices: - volcanoes - earthquakes - tsunamis - landslides A:
landslides
Answer the following question given this paragraph: Coriolis is an effect rather than a force. Coriolis does not force a motion. An object appears to have a change of motion due to the Coriolis effect. Q: What effect causes an object to appear to have a change of motion? Choices: - momentum effect - resonant effect - centrifugal effect - coriolis effect A:
coriolis effect
Q: Answer the following question given this paragraph: Organisms that are obligate aerobes need oxygen to live. That is, they use oxygen as a terminal electron acceptor while making ATP (see the "Cellular Respiration" concept). Humans are obligate aerobes, and so are Mycobacterium tuberculosis bacteria. M. tuberculosis causes tuberculosis (TB). Obligate aerobes are found only in places with molecular oxygen. Q: What do obligate aerobes need to live? Choices: - blood - acid - dioxide - oxygen A:
A: oxygen
Question: Answer the following question given this paragraph: The most common cause of hearing loss is exposure to loud sounds. Loud sounds can damage hair cells inside the ears. Hair cells change sound waves to electrical signals that the brain can interpret as sounds. Louder sounds, which have greater intensity than softer sounds, can damage hair cells more quickly than softer sounds. You can see the relationship between sound intensity, exposure time, and hearing loss in the following Figure below . The intensity of sounds is measured in decibels (dB). Q: The scale that is used to measure the loudness of sound measures their loudness in what? Choices: - waves - weight - centimeters - decibels A:
Answer: decibels

Answer the following question given this paragraph: Near the time of birth, the amniotic sac breaks in a gush of fluid. Labor usually begins within a day of this event. Labor involves contractions of the muscular walls of the uterus, which cause the cervix to dilate. With the mother's help, the contractions eventually push the fetus out of the uterus and through the vagina. Within seconds of birth, the umbilical cord is cut. Without this connection to the placenta, the baby cannot exchange gases, so carbon dioxide quickly builds up in the baby's blood. This stimulates the brain to trigger breathing, and the newborn takes its first breath. Q: During labor, what do contractions of the muscular walls of the uterus cause? Choices: - spontaneous abortion - excretion - premature birth - cervical dilation A:
**Answer**
cervical dilation

Answer the following question given this paragraph: What portion of Earth makes up the "plates" in plate tectonics? Again, the answer came about in part due to war. In this case, the Cold War. The scientists set up seismometer networks during the 1950s and early 1960s. The purpose was to see if other nations were testing atomic bombs. Since seismometers measure ground shaking, they also recorded earthquakes. Q: What are the things moving under the earth's mantle that move the crust? Choices: - crystals - ridges - lava channels - plates A:
(Answer)
plates
