The two sources of new materials involved in geologic processes are:
magma
soil
erosion products
deltas
Although this is not my area of expertise, I would go with magma and deltas.
Magma brings up new material from underneath the earth, and rivers bring new materials into the delta.
The two sources of new materials involved in geologic processes are magma and erosion products. Let me explain how each of these sources contributes to the formation of new materials.
1. Magma: Magma is molten rock that is located beneath the Earth's surface. It is commonly found in the Earth's mantle and occasionally rises to the surface during volcanic eruptions. Magma is a significant source of new materials because, when it cools and solidifies, it forms igneous rocks. These igneous rocks are then subject to various weathering and erosion processes that slowly break them down, creating new sedimentary materials.
To access information about magma as a source of new materials, you can refer to geology textbooks or scholarly articles. These materials will provide detailed explanations about the formation of magma, its composition, and the subsequent processes it undergoes to become new geological materials.
2. Erosion products: Erosion involves the wearing down and removal of rocks and soil from the Earth's surface, primarily due to the action of water, wind, or glaciers. The materials eroded from one location are transported and deposited in another area, leading to the formation of distinct landforms. These eroded materials, such as sediments, contribute significantly to the creation of new geological materials.
To understand erosion as a source of new materials, you can study the field of geomorphology, which explores landforms and the processes that shape them. Geomorphology textbooks and research papers provide insights into erosion mechanisms, the types of materials formed through erosion, and how they contribute to altering landscapes over time.
While soil and deltas are indeed geological components, they are not sources of "new" materials in the same sense as magma and erosion products. Soil is formed through processes involving weathering, erosion, and the accumulation of organic matter, but it primarily represents the weathered and eroded remnants of pre-existing rocks. Deltas, on the other hand, are landforms created by the deposition of sediments at the mouth of a river, but these sediments are typically derived from erosion and transportation rather than being entirely new materials.
