Chapter 19 Study Guide

Scientists have used 'volcanoes' to help locate transform plate boundaries.

The lithosphere consists of:

A scientist who studies seismic waves is called a:

P-Waves are able to travel through:

Secondary waves are only able to travel through liquids inside Earth.

When 2 oceanic plates collide, and cause the subduction of older plates, this is called:

The primary cause of convection currents in the Earth's mantle is believed to be the:

The type of boundary formed as 2 lithospheric plates slide past each other is labeled a_______.

Metamorphic rocks are formed when:

The scientist who first put forth the idea of continental drift was:

Mountain ranges are most often formed at ______ boundaries.

Continental crust is primarily made of:

The name of the ancient super-continent composed of earlier forms of today's continents is:

S-Waves can NOT pass through:

One of the main pieces of evidence for sea-floor spreading is:

The center of the Earth is called:

Seismic waves that mover through the Earth with a side-to-side motion are called:

The best way to detect transform faults is by the _______ they cause.

Metamorphic rocks are formed from intense heat and pressure at 'Convergent'plate boundaries.

The boundary formed as two plates are moving apart from each other is called:

Long chains of undersea mountains called mid- oceanic ridges form at 'Convergent' plates.

As you move from the surface of Earth to the inner core, the density of the materials of Earth:

The distinctive lava found at mid-oceanic ridges is known as:

Oceanic plates are composed mainly of Basalt.

Seismic waves that move with a forward and backward motion are called:

The process which creates new ocean floor is:

Metamorphic rock is formed when heat and pressure change:

Divergent fault boundaries are especially likely to cause earthquakes.

Earth's magnetic field is generated by powerful electric waves inside the:

The Asthenosphere is a zone located:

Sea-floor spreading is the tectonic process that occurs at 'subduction zones'.

Because of the enormous pressure deep inside Earth, the inner core is a :

The movement of tectonic plates is caused by convection cells in the:

Divergent boundaries found on land are known as:

The outermost layer of the Earth is called:

As you move from the surface of Earth to the inner core, the temperature of the layers:

Vibrations that travel through Earth's interior are known as:

The layer which includes all of Earth between the crust and the outer core:

Long chains of undersea mountains are known as:

Rocks are caused to move in a side-to-side motion, in one direction by S-waves.
