Question

question 31
which of the following factors influence the intensity of an earthquake, measured according to the mmi scale? select all that apply.
distance from the hypocenter
type of rock or sediment
surface area of the fault rupture
displacement along fault
time since initiation of the earthquake
question 32
which of the following lines of evidence was not available to alfred wegener when he was developing the continental drift hypothesis?
paleomagnetic polarity records.
the distribution of plant and animal fossils.
the apparent matching shapes of coastlines.
the distribution of paleozoic glacial deposits.

Explanation:

For Question 31: The intensity of an earthquake on the MMI scale is affected by the distance from the hypocenter (the closer, the stronger), the type of rock or sediment (affects shaking), surface - area of the fault rupture (larger can mean stronger), and displacement along the fault (more displacement, more energy released). Time since initiation doesn't directly affect intensity.
For Question 32: Alfred Wegener developed the Continental Drift hypothesis in the early 20th century. Paleomagnetic polarity records were discovered later and were not available to him. The other options (fossil distribution, coastline shapes, and Paleozoic glacial deposits) were evidence he used.

Answer:

Question 31: Distance from the hypocenter, Type of rock or sediment, Surface area of the fault rupture, Displacement along fault
Question 32: Paleomagnetic polarity records
