A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot, molten rock, ash, and gases to escape from below the surface.

Earthquakes are caused by the slow deformation of the outer, brittle portions of "tectonic plates", the earth's outermost layer of crust and upper mantle.
What causes earthquakes?
100
Divergent boundaries occur where two crustal plates are moving away from each other. Remember that this movement is in a relative sense, as both plates could be moving in the same direction, just one moving faster than the other.
What causes divergent boundary to form?
100
Places where plates slide past each other are called transform boundaries.In other places, transform boundaries are marked by features like stream beds that have been split in half and the two halves have moved in opposite directions.
Steps of a Transform Boundary?
100
Yes, this is true when two continental plates are moving towards each other or during an oceanic-continental convergence.
What is the convergent boundary importance understanding the theory of plate tectonics ?

Volcanic rock is an igneous rock of volcanic origin. Volcanic rocks are usually fine-grained or aphanitic to glassy in texture. They often contain clasts of other rocks and phenocrysts.
What are volcanic rocks?
200
Yes! Minor earthquakes have been triggered by human activities such as mining (rockbursts and cavity collapse), the filling of reservoirs behind large dams, and the injection of fluids into wells for oil recovery or waste disposal.
Can people cause earthquakes?

A boundary where the crust/tectonic plates move apart, crust is destoryed, and this forms mid ocean ridges.
What is Divergent Boundary?

A transform boundary is also known as a strike-slip fault.
What is a transform boundary?
200
Where two plates run into each other somtimes one subducts below the other or they go into each other and make folded mountains.
What is Convergent Boundary?
300
When there are no signs of an active magma chamber beneath the volcano (no unusual seismic activity, no volcanic gasses escaping etc.), and when there hasn't been any activity for a long time span (at least 10,000 years).
How do you know when a volcano cannot erupt anymore?

Most earthquake damage is caused by ground shaking. The magnitude or size (energy release) of an earthquake, distance to the earthquake focus or source, focal depth, type of faulting, and type of material are important factors in determining the amount of ground shaking that might be produced at a particular site.
How do earthquakes cause damage?

Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. They are the energy that travels through the earth and is recorded on seismographs.
What Are Seismic Waves?
300
That's where two plates grind past each other with no (or little) compression or tension. You don't build mountains.
What happens at a transform boundary?
300
The three types of convergence can be subdivided into subduction and non-subduction. n the subduction types, you have two plates meeting, and the heavier, denser, cooler plate will dive below the lighter, more buoyant one. As it gets deeper into the mantle, it melts and creates a new magma.
What are three types of convergent boundaries?

Kilauea volcano on Hawaii is the world's most active volcano, followed by Etna in Italy and Piton de la Fournaise on La Réunion island.
What is the the most active volcanoes in the world?
400
No! A common misconception is that of a hole in the ground that opens during an earthquake to swallow up unfortunate victims.
Does the earth open up during an earthquake?

In plate tectonics, a divergent boundary (divergent fault boundary or divergent plate boundary), (but also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
What occurs at a divergent boundary?
400
A transform fault or transform boundary, also known as conservative plate boundary, is a fault which runs along the boundary of a tectonic plate.
What is an example of a transform boundary?
400
Convergent boundary forms when two continental plates collide. Neither plate subducts because the crusts have approximately the same density.
How are mountains formed in convergent boundaries?
500
here are many ways to become a volcanologist, but most volcanologist have gone more traveling and visited many volcanoe in the world, attended conferences and workshopy about volcanoes.
How did you become a volcanologist?
500
No, except for very rare exceptions. Every year, hundreds of earthquakes occur in Canada. Only a very tiny minority of these precede a larger earthquake.
Does a small earthquake mean that a larger earthquake is coming?
500
The boundary between Pacific and Antarctic plate.
Examples of a divergent boundary?
500
Transform boundaries are boundaries where two tectonic plates are sliding next to one another.
Transform boundaries, what do they form?
500
Well, a convergent boundary is when two plates are heading the same direction and one submerges beneath the other. an example of such is the himalaya mountains.. they occurred when two continental plates collided.
Can you name one example of a convergent boundary plate?
