The San Andreas fault in California is visible at the Earth’s surface. Would you like to live in a house right there?

The San Andreas Fault Line: Is Your Home At Risk? Many People Do!

Transform (Rotational) Boundaries Occur where tectonic plates slide by each other. Do not make or destroy crust. Create earthquakes in California.

The Hawaiian Islands were made by a hot spot. The Hot Spot stays in one place, but the crust above it moves.

Hot Spots Thin parts of the Earth’s crust. Heat from the Mantle can “escape”. Creates Volcanoes & Geysers.

Which block diagram best represents the relative direction of plate motion at the San Andreas Fault?
