Question

Plate Boundaries and Crust Types

Using the plate tectonics map, find one example of each of the following combinations tectonic plate boundary type and crust type. For each one, indicate where it is located geographically, name the plates involved, and list the tectonic, seismic, volcanic, and surface features that found there.

Convergent boundary between oceanic crust and continental crust

Convergent boundary between continental crust and continental crust

Divergent boundary between oceanic crust and oceanic crust

Divergent boundary between continental crust and continental crust

Transform boundary between continental crust and continental crust

Plate Movement

A. Indicate the approximate direction of movement of both the North American and Pacific plates. Indicate the direction the plate is moving towards. Examples: north, northeast, east, southeast, etc.

Direction of North American Plate:

Direction of Pacific Plate:

B. Explain why Seattle, Washington, and Portland, Oregon, have to worry about the direct effects of volcanoes, but San Francisco, Los Angeles, and San Diego don’t?

Explanation / Answer

A- divergent boundary condition is acting there and there expected movement is-

north american plate - west-southwest

pacific plates- northwest

B- Seattle,Washington Portland and Oregon should be worried because volcano situates there or near by them are active which can affect tremendusly where as on the other hand volcano near by San Francisco, Los Angeles and San Diego are not active so yet safe.

Examples of given question above A and B

# convergent boundry betweeen oceanic crust and continental crust - its between nazca plate and south american plate.

# convergent boundry between continental crust and continental crust- eurasian plate and arabian plate.

# divergent boundry between oceanic crust and oceanic crust- pacific plate and antartic plate.

#divergent boundry between continental crust and continental crust- african plate and arabian plate.

# transform boundry between continental crust and continental crust- northen amreca plate and san abdreas.
