Question

question 3 (2 points)
two volcanoes erupt: one explodes violently, and the other releases slow - moving lava flows. what is the most likely cause of this difference?
○ a the age of the volcanoes
○ b the amount of rain in the area
○ c the thickness and behavior of the lava
○ d the height of the volcanoes
question 4 (2 points)
an earthquake occurs, but very little damage is reported at earth’s surface. which explanation best fits this situation?
○ a the earthquake released very little energy
○ b the earthquake occurred far below the surface
○ c the earthquake happened near a volcano
○ d the earthquake was not recorded by instruments

Explanation:

For Question 3: The thickness and viscosity (behavior) of lava directly determine volcanic eruption style. Thick, viscous lava traps gas, causing violent eruptions, while thin, runny lava flows slowly.
For Question 4: The amount of energy an earthquake releases dictates the level of surface damage. Low energy earthquakes result in little to no damage.

Answer:

Question 3: c. The thickness and behavior of the lava
Question 4: a. The earthquake released very little energy
