Tectonic Activity on Venus Differs from That on Earth in That

question 98

Multiple Choice

Tectonic activity on Venus differs from that on Earth in that

• A) active crustal deformation appears to be completely absent.
• B) the lithosphere appears to be softer or more plastic and cannot support the creation and motion of solid plates (flake tectonics).
• C) the lithosphere appears to be cooler and thicker and is therefore too rigid to break up into moving plates.
• D) mantle convection appears to be more vigorous and has broken the lithosphere into a multitude of small plates instead of a few large ones.

Observed Frequencies

The actual number of occurrences of events measured or recorded during a study or experiment.

Normal Distribution

A symmetric bell-shaped frequency distribution that is fully defined by its mean and standard deviation.

Intervals

Ranges between two points or values, often used in statistics to indicate the confidence or probability associated with a specific estimate.
