rock
Melting of a rock at temperatures below its melting point would not produce liquid rock below the surface. The other processes, such as increased temperature or pressure, would lead to the formation of liquid rock.

Processes on and near Earth's surface primarily produce sedimentary rocks. These rocks form through the accumulation and compaction of sediments, which can include fragments of other rocks, minerals, and organic material. Additionally, volcanic activity can lead to the formation of igneous rocks at or near the surface. Weathering and erosion also play crucial roles in creating and transporting materials that contribute to sedimentary rock formation.
Processes on and near Earth's surface primarily produce sedimentary rocks. These rocks form through the accumulation and lithification of sediments, which can include fragments of other rocks, minerals, and organic materials. Additionally, weathering and erosion of igneous and metamorphic rocks contribute to the formation of sedimentary layers. Examples include sandstone, limestone, and shale.
Weathering is the process by which rocks break down in place to produce soils and sediments. It can occur through physical processes like freezing and thawing, as well as chemical processes like oxidation and hydrolysis. Over time, weathering contributes to the formation of Earth's surface features.
The study of Earth's surface landforms is known as geomorphology.
Minerals can form on Earth's surface through various processes such as crystallization from molten rock, precipitation from water, and deposition from volcanic gases. These processes involve the cooling and solidification of materials, resulting in the formation of mineral crystals. Weathering and erosion of existing rocks can also contribute to the formation of new minerals on the Earth's surface.
The two processes that result in the formation of igneous rocks are cooling and solidification of molten magma, and crystallization of magma within the Earth's crust or on the surface. These processes lead to the solidification of molten material, which then forms igneous rocks.
Chemical processes involve using chemical reactions to produce desired products, while bio-processes use biological systems like enzymes, microorganisms, or cells to produce products or carry out reactions. Bio-processes are often considered more sustainable and environmentally friendly compared to chemical processes, as they make use of renewable resources and can potentially generate less waste.
Surface ozone is produced by the reaction of volatile organic compounds (VOCs) and nitrogen oxides (NOx) in the presence of sunlight. Emissions from vehicles, industrial processes, and power plants are major sources of VOCs and NOx, leading to the formation of ground-level ozone.
Igneous rocks are formed through two processes: cooling and solidification of molten rock (magma) on or beneath the Earth's surface (extrusive), and cooling and crystallization of magma deep beneath the Earth's surface (intrusive).
Plutonism refers to the formation of igneous rocks beneath the Earth's surface, through the cooling and solidification of magma. Volcanism, on the other hand, involves the eruption of magma from beneath the Earth's surface onto the surface, resulting in the formation of volcanic landforms like mountains and lava flows. Both processes are part of the larger geological cycle of rock formation and erosion.
