It changes because when the 2 tectonic plates collide they form mountains and volcanoes. Also with Alfred Weigners hypothesis the continents are always moving
Continental drift and subduction zones the tectonic plates along the earth. continental drift causes tectonic plates to either "pull apart" or "crash" into each other. plates that crash into each other either form mountains, or when one slides under the other (a subduction zone) volcanoes from. *see "Volcanoes" for further explanation)
What else can I help you with?
What are moving pieces under the earths surface that form the earths crust?
Tectonic plates are the moving pieces under the Earth's surface that form the Earth's crust. These plates float on the semi-fluid asthenosphere and interact with each other through processes like subduction, spreading, and collision, which contribute to the shaping of Earth's surface features.
Why is the earths crust always moving?
Simple- Convection in the mantle causes mantle to slowly move, and it pushes against the crust. As it does this, the tectonic plates move.
How many plates are on the earths crust?
46
Plates are large sections of Earths what?
The crust
What is plate tectonic plates?
its the earths crust
What are the sections of earth's are the plates in?
earths crust
What are volcanoes and what causes them?
a volcano is a rupture or opening in the earths crust. caused by convergent (coming together) or divergent (moving apart) plates
What causes the earths crust to rise and fall?
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
Are the tectonic plates in the earths inner core?
No the tectonic plates are on top of the crust.
How many large plates on earths crust?
7
What are plate movement?
the movement of earths plates or crust
What is the movements of plates of the earths crust you?
Plate Techtonics.
