The plate tectonic theory states that new Earth crust is being formed while old crust descends back into the mantle. Uneven heating in the mantle causes convection which keeps the crust in motion. The constant movement of Earth's plates are the result of the three types of boundaries, divergent, convergent, and transform, and the convection in the mantle.
What else can I help you with?
What hypothesis proposed that earth's continents were once joined in a single landmass and then gradually moved apart?
The hypothesis that Earth's continents were once joined in a single landmass and then gradually moved apart is known as the theory of continental drift, proposed by Alfred Wegener in 1912. This theory laid the foundation for the development of the theory of plate tectonics.
What did the theory of plate tectonics replace?
The theory of plate tectonics replaced the older theory of continental drift. It provided a more comprehensive explanation for the movement of Earth's lithospheric plates and the processes that shape our planet's surface.
What theory states that plates move around on the athenosphere?
The theory that states that plates move around on the asthenosphere is called plate tectonics. This theory explains the movement of the Earth's lithosphere into different plates and their interactions at plate boundaries due to the convective currents in the asthenosphere beneath them.
Which theory describes the motion of earth's crust on its mantle?
plate tectonics=D
What geological theory states that pieces of the Earth's lithosphere are in constant slow motion?
The theory of plate tectonics states that pieces of the Earth's lithosphere, called tectonic plates, are in constant slow motion, driven by processes such as seafloor spreading, subduction, and continental drift. These movements can result in events like earthquakes, volcanic eruptions, and mountain formation.
THEORY OF PLATE TECHTONIC?
When the Continental Drift Theory applies; when two plates either collide, smash, or slide to move plate techtonics.
What techtonic plate is japan on?
Ur mummas plate
What builds up to make an earthquake?
energy from plate techtonic
How is plate tectonics related to landslides?
because it is a type of techtonic plates
What does plate tectonics mean?
It's a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle.
What massive techtonic plate does the United states reside over?
San Andreas
What formed the island maui?
A volcanic 'hot spot' in the pacific techtonic plate.
What is the Plate under the ocean?
Techtonic plates move under the earth moving land and water.
What is a thrust volcano?
its the techtonic plates. one plate slides over the other which = trust from action
What created the Himalayan mountain range?
It is caused by the Techtonic plate on which India sits colliding with the techtonic plate to its north. This process is still going on and the Himalayas are still increasing in height as a result of it.
Why do earthquakes happen in California more often than Texas?
more techtonic plate coliding in California
What happens to the layers of the Earthduring a earthquake?
The techtonic plates are shifting. One plate is being overlaped by the other.
