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

Because of a decrease in pressure.

Which type of landform develops at plate boundaries where one oceanic plate descends beneath another

A volcanic island arc

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

What are the volcanic landforms at divergent ocean plate boundaries called

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

A lava flow with a surface of rough jagged blocks and sharp angular projections is called

aa (pronounced ah-ah)

What is newly formed land consisting of an arc-shaped island chain called

Volcanic island arc

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. 

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 is a sheet like body that cuts across rock layers and is produced when magma is injected into a fraction is called

A dike I got it right on a test

What was the reason wegeners continental drift hypothesis was rejected

His evidence was incorrect.

How do uplift and erosion help to form a batholith

by exposing a large body of igneous rock to the surface

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

magnitude

Rocks can melt without changing temperature when the pressure exerted on them is .

Increase

What does most magma forms from

Magma is liquid rock from volcanoes.

How do ancient glacial deposits in Africa India Australia and South America support the idea of continental drift
