How do you think low atmospheric pressures might affect a climber's breathing?
Answer:
The decreased atmospheric pressure and low levels of oxygen can have very dangerous effects on a climber's body. Even though there is less oxygen available to the climbers, their bodies can learn to compensate. The human body survives by breathing air into lungs.
According to the model proposed by geophysicist J. Tuzo Wilson, hot spots are caused by a. friction due to the lithosphere sliding atop the asthenosphere. b. unusually dense concentrations of radioactive isotopes at various points in the crust. c. hot plumes of mantle material that rise up through cooler, denser surrounding rock. d. zones of localized subduction that produce melting of the mantle.
Answer: c. hot plumes of mantle material that rise up through cooler, denser surrounding rock
Explanation:
A hot spot is simply refered to an area that is very hot below the Earth. Here, the magma is typically hotter than the magna of its surrounding. It should be noted in this case that the magma plume then results in volcanic activity.
According to the model proposed by geophysicist J. Tuzo Wilson, hot spots are caused by hot plumes of mantle material that rise up through cooler, denser surrounding rock. Therefore, the correct answer is C.
