Type $344616.16 \mathrm{~N} 1184458.19 \mathrm{~W}$ into the search bar in Google Earth and zoom out to an eye altitude of 10 miles. Quail Lake is a dammed river that is sitting directly over top of the San Andres Fault, which is a well-known transform boundary with the North American Plate on the northern side and the Pacific Plate on the southern side. This boundary is running East-West in this area and you may be able to see the boundary better by zooming out. Examine the path of the river that feeds into and flows out of Quail Lake. What direction is the North American plate moving in comparison to the Pacific Plate at this location? a. East b. West

Key Concepts

Plate Tectonics

This fundamental concept describes the large-scale motion and interaction of Earth’s lithospheric plates. It encompasses the processes by which plates move over the semi-fluid asthenosphere, leading to various geologic phenomena including earthquakes, mountain building, and the creation or destruction of oceanic and continental crust.

Transform Boundaries

A transform boundary is a type of plate boundary where two plates slide past one another horizontally. The relative lateral motion along these faults can result in prominent strike?slip faults, such as the San Andreas Fault system, where two plates grind against each other without the typical convergent or divergent interactions.

Relative Plate Motion

This concept refers to the movement of one tectonic plate in relation to another. At transform boundaries, observing the relative motion—such as the way the North American Plate and the Pacific Plate slide past each other—helps geologists interpret the direction and rate of plate movement and its geologic consequences.

Geomorphology as an Indicator of Tectonic Processes

Geomorphic features, including river paths and offsets, can serve as indicators of underlying tectonic activity. In regions along transform boundaries, the deformation of river courses can reveal the direction of plate motions, as the landscape is continuously shaped by the relative sliding of adjacent plates.
