Final answer:
The Earth's crust is formed through folding of bedrock, accretion of exotic terranes, orogenesis, and volcanic eruptions.
Step-by-step explanation:
The Earth's crust, or lithosphere, is formed through a combination of processes including folding of bedrock, accretion of exotic terranes, orogenesis, and volcanic eruptions. These processes contribute to the creation of the Earth's crust and the formation of different landforms.
Folding of bedrock occurs when tectonic forces cause compression and bending of rocks, resulting in folded layers. This process is commonly observed in mountain ranges.
Accretion of exotic terranes refers to the addition of land masses to existing continents through tectonic collisions. This process leads to the formation of diverse geological features.
Orogenesis refers to the process of mountain building, which involves intense tectonic forces causing the uplift and folding of rocks, resulting in the formation of mountain ranges.
Volcanic eruptions contribute to crustal formation through the extrusion of molten rock, or lava, onto the Earth's surface. This process adds layers of solidified lava, contributing to the growth of the crust.
