These waves can move through solid rock and fluids, like water or the liquid layers of the earth?

(a)  

It pushes and pulls the rock it moves through just like sound waves push and pull the air

(a)  

It is also known as compressional waves, because of the pushing and pulling they do?

(a)  

These waves particles move in the same direction that the wave is moving in, which is the direction that the energy is traveling in, and is sometimes called the direction of wave propagation?

Earthquakes occur along the fractures that appear as?

(a)  

Causing one of the slabs of the lithosphere to subduct beneath an overriding plate?

(a)  

It is a region where the crustal plates are moving apart?

(a)  

It is a boundary produced when two plates slide past each other?

(a)  

It is a cracks in the lithosphere caused by the stresses created as sections of a plate (or two plates) which are moving in different directions?

(a)  

In some ways, our planet resembles like a giant jigsaw puzzle because its outer surface is composed of about?

(a)  

20 tectonic plates with enormous sections that roughly fit together and meet at places called?

(a)  

It is important since they are often associated with earthquakes and volcanoes?

(a)  

When Earth’s tectonic plates grind past one another, enormous amounts of ? can be released in the form of earthquakes.

(a)  

Volcanoes are also often found near?

(a)  

The thinner and denser oceanic plate is overridden by the thicker and less dense continental plate. The oceanic plate is forced down into the mantle in a process known as?

(a)  

At a depth of about ?, materials in the subducting plate begin to approach their melting temperatures and a process of partial melting begins.

(a)  

These are produced as a result of this melting, and the magma is lower in density than the surrounding rock material?

(a)  

Magma chambers that reach the surface break through to form a?

(a)  

In divergent boundaries, extensional forces stretch the lithosphere and produce a?

(a)  

It forms a transform plate boundary is known as a transform fault?

(a)  

It is warm mantle currents drive and carry plates of lithosphere along a like a conveyor belt?

(a)  

It is newly formed plates at oceanic ridges are warm, and so have a higher elevation at the oceanic ridge than the colder, more dense plate material further away?

(a)  

It is older, colder plates sink at subduction zones, because as they cool, they become more dense than the underlying mantle?

(a)  

Gravity causes the higher plate at the ridge to push away the lithosphere that lies further from the ridge?

(a)  

The cooler sinking plate pulls the rest of the warmer plate along behind it?

(a)  

It describes the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth’s lithosphere, since tectonic processes began on Earth between 3.3 and 3.5 billion years ago?

(a)  

It deals with the dynamics of Earth’s outer shell- the Lithosphere- that revolutionized Earth sciences by providing a uniform context for understanding mountain-building processes, volcanoes, and earthquakes as well as the evolution of Earth’s surface and reconstructing its past continents and oceans?

(a)  

These are three of the forces that have been proposed as the main drivers of plate movement?

(a)  

On the other hand, recent research has shown that the major driving force for most plate movement is?

(a)  

It is also presented in recent researches to be a force that drives the movement of plates?

(a)  

This Pangaea started to break into two smaller supercontinent called?

(a)  

This Pangaea started to break into two smaller supercontinent called Laurasia and Gondwanaland during the?

(a)  

It is a system is a device that bounces sound waves off underwater objects and then records the echoes of these sound waves?

(a)
