The fundamental landforms are thought to be the result of the Earth's subsurface motions, according to the scientific theory of plate tectonics.
The magnetic field of the planet is created by the spinning of the Earth's liquid outer core.
Unsurprisingly, the internal makeup of the Earth has an impact on plate tectonics. Because it is cooler and more dense than the deep mantle, the upper mantle is similar to the overlying crust in many ways.
Mountains will grow when plates converge or push together, and as plates pull apart or diverge, continents will split and oceans will arise.
The Earth's geography has changed significantly over the span of millions of years as a result of the continents passively drifting with the plates.
<h3>What is the theory of plate tectonics?</h3>
The widely recognized scientific hypothesis known as plate tectonics postulates that the Earth's lithosphere is made up of many sizable tectonic plates that have been steadily moving for around 3.4 billion years.
An estimated 50-80% of all life on earth is found under the ocean surface and the oceans contain 99% of the living space on the planet. Less than 10% of that space has been explored by humans.
