Which layers of the earth compose the earth's plates?
The lithosphere (which is composed of the crust and solid brittle upper mantle) makes up the Earth's tectonic plates.
What is it called when scientists refer to the earth being all as one large land mass before the tectonic plates shifted and parts of the earth were divided?
This was known as Pangaea.
How much can tectonic plates move by?
The average rate of movement of tectonic plates per year is roughly one to two inches. Individual parts of interacting plates can move more than several feet during earthquakes. Over large time spans, tectonic plates can move to all parts of the globe.
What is the 'why' and not the 'how' for earthquakes happening?
Because heat rises from the earth's mantle and creates such pressure that the parts of the crust called tectonic or lithospheric plates move is the reason why earthquakeshappen.
Where do oceanic trenches form?
At the margins of colliding tectonic plates.
What are the moving parts of the earth's crust?
Tectonic Plates
What cause faults and earthquakes?
Movement of tectonic plates which are parts of the Earth's crust.
What is stable and does not move with tectonic plates?
Nothing, all parts of the earth are moving relative to the other parts.

What is the jigsaw like parts of the earths crust called?
Tectonic Plates
Why are no volcanoes found in certain parts of world?
Volcanoes are only found on the edge of tectonic plates & they can also be found on cracks in the tectonic plates which is un-common
Im the gap that forms as tectonic plates move apart?
Oceanic trenches are the gaps which form when the tectonic plates move apart. They are the very deepest parts of the ocean.
Are tectonic plates large and small slabs of rocks?
Tectonic plates are very large (their highest points form the continents) and constitute the hard crust of the planet. They sit afloat the mantle - molten material called magma - and they are formed from- and return to- magma as parts of the plates are cooled or heated.

Because heat rises from the earth's mantle and creates such pressure that the parts of the crust called tectonic or lithospheric plates move is the reason why earthquakeshappen.
What kind of tectonic plate is mt.erebus?
Mt. Erubus has tectonic plates made up of parts of the lithosphere. These plates grind together or pull apart and this causes volcanoes to erupt.
