Tectonic plates is a theory that the lithosphere is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.
Tectonic plates float on top of the molten rock and moving around the planet. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.

Answer:
False.
Explanation:
The Mid-Ocean ridge is the<u> largest </u>chain of mountains in the world. The majority of it is underwater. It forms due to the movement of the different tectonic plates in the world, which allows the raising and solidification of magma where the plates diverge from each other, creating the ridge.
As it forms where the plates diverge, which is in several places on Earth, it extends along the seafloor into all the Earth's oceans.
The main factor that shapes the life and eventual death of a star is how much mass it began with. A star that is 2.8 times the mass of our sun will most likely end up as a white dwarf.
When medium size stars are near the end most of the hydrogen core has been changed to helium. The helium core then begins to shrink and as this happens the core heats up. The energy that is released by the core heating up causes the the outer hydrogen shell to expand greatly. As the shell expands it cools and the colour changes to red.
The helium core will continue to heat up until the helium atoms start to fuse to form carbon atoms. When all the helium is fused to carbon it begins to die and gravity causes the last of of the star's matter to collapse inward forming a white dwarf.
Answer: The Himalayan mountain range and Tibetan plateau have formed as a result of the collision between the Indian Plate and Eurasian Plate which began 50 million years ago and continues today.
