The rock cycle consists of the processes in which rocks are continually changed over long periods of time.

At a convergent boundary, plates move toward each other and collide.

A volcano is an opening in Earth's crust that releases lava, smoke, and ash when it erupts.

An Earthquake is the shaking of the ground caused by the sudden release of energy stored in rocks.

A sheild valcano is made of gentaly sloping layers composed entirely of cooled lava. Sheild valcanoes are the largest (in area)of the three main types of valcanoes. Sheild valcanoes do not erupt violently as do the cinder cones.

Erosion is the transportation of sediments to another location.

at a divergent boundary, plates move away from each other.

An eruption is when a volcano becomes alive.

A fault is the surface along which rocks break and move.

A hot spot is an area of valcanic activity produced by magma riasing from the mantle. The tempeture under the crust at a hot spot is much higher than elsewhere. As a result,magma is forced upward through cracks in Earth's crust.

Chemical weather occurs when chemical changes disolve the minerals in rocks or change thwe minerals into diffrent minerals.

he proposed that some plates slide passed each other along what he called transform boundary.

A non-active volano is called a dormant.

A primary wave or P wave is the fastest traveling wave out of all three waves. P waves can pass through solids, liquids, and gases. Primary waves cause a slight vibration (compression) that might rattle dishes on the shelves.
What is a Primary wave?

The place deep in the crust where an Earthquake begins is called the focus of an Earthquake.
What is Focus?

Weathering is breaking down of rocks into sediments.

The theory of plate tectonics proposes that the plates on Earth's lithosphere interacts with each other.

A vent is a hole in the volcano which magma emerges from.

A secondary waves or S waves travel more slowly than P waves. S waves can pass only through solidds, not through liquids or gases.
What are Secondary wave?

The surface location directly above the focus is called the epicentre. Surface waves travel out of the epicentre.
What is Epicentre?

Mechanical weathering occurs when rocks are broken apart physical processes.

Tectonics is the study of the movement of large scale structual features on earths crust.

a cinder cine valcano is made of cinder with steep and a bowl-shaped crater at the top.
What is a cinder cone volcano?

Surface waves are the slowest of all three waves, but their rolling motion breaks up roads and buildings. Surface waves cause the most damage during earthquakes.
What are Surface waves?

The record of seismic waves detected by a seismograph is called a seismogram. Most modern seidmographs are elctronic, but they are based on the same principles.
