Because of the convection currents of the molten rock in the interior of the Earth.
A tectonic plate The Earth's surface is made up of a series of large plates (like pieces of a giant jigsaw puzzle). These plates are in constant motion travelling at a few centimetres per year. The ocean floors are continually moving, spreading from the centre and sinking at the edges.
The Earth's crust is not stationary; it is made up of tectonic plates that constantly move and interact with each other. This movement results in earthquakes, volcanic activity, and the formation of mountains. It is a dynamic process known as plate tectonics.
A fracture in the crust of the earth is called a fault. Faults are caused by the movement of tectonic plates and they can result in earthquakes when the built-up energy is released suddenly.
The thick inner soup on Earth is known as the mantle and is composed of solid rock that can flow over long periods of time. It lies between the Earth's crust and core.
Sea floor spreading occurs due to the movement of tectonic plates away from each other. This movement creates a gap or rift at the mid-ocean ridge where magma rises up from below the Earth's crust, solidifying to form new crust. Over time, this process results in the continuous widening of the sea floor.
The tectonic plates are constantly moving
Yes, materials such as oil, gas, and minerals can leak into the Earth's crust through natural processes like tectonic movements and volcanic activity. Additionally, human activities like drilling for oil or gas can also lead to unintentional leaks into the Earth's crust, which can have environmental consequences.

Tectonic Plates
No, the Earth's crust is not stationary. It is divided into several tectonic plates that are constantly moving due to the convection currents in the Earth's mantle. This movement is responsible for phenomena like earthquakes, volcanic eruptions, and the creation of mountain ranges.
They are called plate tectonics.
The amount of crust on Earth remains relatively constant because crust is neither created nor destroyed in significant amounts. Earth's crust is continually recycled through processes like subduction and seabed spreading, leading to a balanced crustal mass over time.

Yes, the crust is the top layer. It continually changes.
The Earth's crust is not stationary; it is actually broken into several large pieces called tectonic plates that are constantly moving. These plates interact at their boundaries, leading to geological phenomena like earthquakes, volcanoes, and mountain formation.
