Major geologic events such as earthquakes, volcanic eruptions, and mountain building result from lithospheric plate motions. Landforms and sea-floor features are the result of a combination of constructive (crustal deformation, volcanic eruptions, deposition of sediment) and destructive (weathering, erosion) processes. The primary cause of continental drift, earthquakes, and volcanic eruptions is
A. convection currents beneath Earth's crust.
B. the rotation of Earth on its axis.
C. the gradual sinking of the earth's crust D. heat form the Sun warming Earth

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
