Where do volcanoes most commonly happen?
cracks in the plates which make up the crust. the earths crust is not connected. its made up of plates that moves and they are formed by plates pushing together then collapsing. they erupt when it gets a lot of friction from the plates pushing together
How do earthquakes can be used to infer plate boundaries?
alright so when tectonic plates meet there are earthquakes because when the plates collide with each other because the earth is always moving it creates giant earthquakes that push and pull the tectonic plates on the crust of earth causing earth quakes. Volcanoes form at the boundaries of tectonic plates because it is one of the only places on the earths crust where there are holes in the crust so the liquid mantle (lava) can escape through the earths crust. forming volcanoes.
Earthquakes result when forces push what along faults in earths lithosphere?
Earthquakes result when forces push plates along faults in the Earth's lithosphere. These plates are comprised of the crust and a portion of the upper mantle.
What is the tectonic plates in earth's crust?
plates of the earth's crust that float on top of the molted mantle layer.
The crust is only what of earths thickness?
half of earths layer

What theory explains how the continents rest on large plates on the earth's crust?

What is the theory that explains how large pieces of Earths outermost layer move around?
It's called 'plate tectonics' - and explains that the Earth's crust is composed of large pieces (or plates) that 'glide' over the molten mantle beneath.
What theory of the formation and movement of the plates that cover the earths surface?
the movement and formation of the plates or continents is caused by conduction under the crust.
What is the theory of formation and movement of the plates that cover the earths surface?
the movement and formation of the plates or continents is caused by conduction under the crust.
What is the scientific theory that says the large plates of the Earths outer crust float on the surface?
Plate Tectonics!
What part of earth contains plates?
The crust. All of the Earths crust are part of techtonic plates.

earths crust
How many plates are on the earths crust?
