The rock cycle is a continuous process that involves the formation, breakdown, and transformation of rocks within Earth's crust. It plays a crucial role in shaping the Earth's surface and geology. Rocks are constantly being formed through processes like cooling and solidification of magma, weathering and erosion of existing rocks, and the deposition and compaction of sediments. These rocks can then undergo further changes through processes like heat and pressure, melting and recrystallization, and uplift and exposure. The rock cycle helps to recycle and redistribute materials within the Earth's crust, contributing to the dynamic nature of the planet's geology.
Magma that hardens within the Earth's crust is called intrusive igneous rock. This type of rock forms when magma cools and solidifies beneath the Earth's surface, resulting in the formation of intrusive features like batholiths, dikes, and sills.
Pressure plays a significant role in the formation and transformation of rocks. High pressure can cause rocks to change their structure and composition, leading to the formation of new types of rocks through processes like metamorphism. This pressure can come from the weight of overlying rocks or tectonic forces, and it can also affect the temperature at which rocks form. Overall, pressure is a key factor in shaping the Earth's crust and the rocks within it.
Processes such as melting, recrystallization, and metamorphism occur deep in the Earth's crust. These processes involve high temperatures and pressures that cause rocks to change their form and composition.
Continental crust contains granite. This type of crust is thicker and less dense compared to oceanic crust. Granite is a common rock in the continental crust due to its formation through the cooling and solidification of magma below the Earth's surface.
crust
It shows that the rock is a plutonic rock and was formed as a result of slow cooling within the earths crust/interior.
the movement and formation of the plates or continents is caused by conduction under the crust.

magma
Earth's plates or crust can cause earthquakes, volcanic eruptions, and the formation of mountain ranges due to tectonic plate movements and interactions. Subduction zones can also lead to the formation of deep ocean trenches and volcanic arcs.
Geothermal energy is from heated water within the earth's crust.
Tectonic plates which may be either oceanic or continental in nature.
Physical samples of rock extracted (taken) from deep within Earths crust.

No. Earth's crust does not convect. Convection in the mantle, however can create hot spots and rifting, which can lead tot he formation of volcanoes.
The Earths crust is approximately 650 km deep.
