Weathering is the process that changes rocks into soil, sand, and sediment through physical, chemical, or biological means. It involves the breakdown and alteration of rocks at or near the Earth's surface over time.
The process in which rocks first bend and then break is called deformation. Deformation occurs when rocks experience stress, which can be caused by tectonic forces, pressure, or temperature changes. Initially, rocks may bend or fold under this stress, but if the stress is too great, the rocks can eventually break or fracture.
The Rock Cycle.
Answering "What process changes igneous rocks into metamorphic types?"Igneous rocks convert into metamorphic due to extreme pressure and heat, which can come from magma/lava or the movement of tectonic plates. For example, the igneous rock basalt eventually turns into the metamorphic rock granulite.
Subduction and high pressure.
When heat from nearby magma causes changes in surrounding rocks, a process called contact metamorphism occurs. This process includes changes in rock texture and mineral composition due to the high temperature and pressure from the magma. This usually results in the formation of new minerals and textures within the rocks.
A process that changes rocks without changing the minerals they are made of is called metamorphism. This occurs when rocks are subjected to high temperatures and/or pressures, causing them to undergo physical and chemical changes. Metamorphism can result in the formation of new mineral crystals, recrystallization of existing minerals, and the development of new textures within the rock.
The process that changes the shape of rocks is called weathering. Weathering occurs through physical (e.g. freezing and thawing) or chemical (e.g. acid rain) processes that break down rocks into smaller particles, ultimately changing their shape and composition over time.
The process in which rocks change shape is called deformation. During deformation, rocks undergo changes in shape, volume, or orientation in response to stress. This can result in the formation of folds, faults, and other structural features in rocks.
Rocks weather due to the breakdown and alteration of their minerals over time. Factors like water, wind, temperature changes, and living organisms contribute to the process of rock weathering by causing physical and chemical changes to the rock's surface.
Sedimentary rocks must be subjected to high temperature and pressure within the Earth's crust to become metamorphic rocks. This process, known as metamorphism, causes changes in the mineral composition and texture of the sedimentary rock, resulting in the formation of metamorphic rocks.
