Flux Melting happens due to what?

Addition of volatiles (water) to the upper mantle.

200

What boundary will often have both normal and strike slip faults?

Divergent (Mid-ocean Ridge)

Which process explains magma generation and volcanism along mid-ocean ridges?

Decompression melting

300

Following a major earthquake, tsunamis typically occur at this type of plate boundary:

Subduction Zone (convergent)

300

Biblical scriptures or genealogies

300

What is the largest shield volcano in the solar system?

Olympus Mons

300

Some secondary effects of earthquakes are (4)

Fire, Tsunami, Liquefaction, and Landslides

400

Which volcanoes are associated with subduction zone volcanism?

Stratovolcanoes

400

Deep-focus earthquake occur at which type of plate boundary?

Subduction zone (convergent)

400

An unconformity can occur in the rock record due to:

Erosion

400

The largest and most explosive eruptions are

Caldera forming events.

400

Stick slip motion describes

the start and stop motion of a fault due to friction

500

Which type of volcano and eruption are associated with basaltic magma?

Shield and Effusive

These seismic body waves arrive first to the seismic station:

P-waves

500

Based on the principle of cross-cutting relations, a fault that cuts across a sedimentary rock layer, would be considered _______ than the sedimentary rock layer.

Younger

500

Why do we have decompression melting of the mantle

The removing of pressure that confines the mantle allows the mantle to melt.

500

Elastic Rebound Theory describes

the elastic release of strain due to the stick slip motion.
