At divergent plate boundaries in the ocean magma rises and melts because of what

Because of a decrease in pressure.

How much of an increase in wave amplitude is seen from an earthquake measuring 5.4 on the Richter scale compared to one measuring 4.4

Ten times

How do scientists classify intrusive igneous features

according to shape, size, and their relationship to surrounding layers of rock

The collision and joining of crustal fragments to a continent

mamga <-Lies get out.

Accretion is the correct awnser.

What are the volcanic landforms at divergent ocean plate boundaries called

The volcanic landforms at divergent ocean plate boundaries are oceanic ridges.

What is the difference of the P waves and S waves used to locate an earthquake's epicenter

P waves, also called primary waves, are the first waves to be registered on a seismograph. The S waves, or secondary waves, are the second and slower wave to register on the seismograph. When locating an earthquakes epicenter seismologists take the first reading of the P wave, and then take the reading from the S wave. At the station of where the earthquake was recorded, seismologists draw a large circle from where the earthquakes epicenter could be. TO exactly located the earthquakes epicenter there needs to be at least 3 dfferent staions where the earthquake hit to determine its epicenter using the S and P time interval. 

What is a lens-shaped intrusive igneous mass that forms close to Earth's surface

I believe it's laccolith - NovaNet

Why was Alfred wegeners idea that tidal forces might cause continental drift refuted as impossible

It would stop earth's rotation.

Showed that the tidal forces needed to move continents would stop earths rotation.

What was the reason wegeners continental drift hypothesis was rejected

His evidence was incorrect.

A caldera is a depression in a volcanic mountain A caldera may form when

The mountain collapses into an emptied magma chamber

Which factors help determine whether a volcanic eruption will be explosive or relatively quiet

The volatile content of the magma.

Weather water or Ice has ingres to the volcanic vent.

The physical stability of the volcano.

The trace that records an earthquake from seismic instruments is called a

magnitude

An accumulation of different sedimentary and metamorphic rocks combined with scraps of ocean crust is called

accretionary wedge
