The sphere that extends from Earth's core to Earth's crust is known as the mantle. It is the layer of the Earth located between the core and the crust and consists of solid rock that is capable of flowing over long periods of time. The mantle plays a crucial role in the movement of tectonic plates and the convection currents that drive the Earth's geological processes.

The long deep cracks in the Maria Bedrock on the Moon are called rilles. These are narrow, trench-like depressions that can be several kilometers wide and hundreds of kilometers long. Rilles are thought to have formed from a combination of volcanic and tectonic processes.
No, Earth's crust movement has been occurring for billions of years as part of the process of plate tectonics. The movement of the Earth's crust has shaped the planet's surface and continues to do so over long geological timescales.
Extrusive igneous rock- Sometimes lava erupts and flows from long cracks in the earths crust called fissures. Lava flows from fissures on the ocean floor at places where tension is causing the ocean to be pulled apart. This lava cools to form new ocean floor. Hope it helps.
