weathering
Weathering is the most direct process that helps create soil from rocks. Physical weathering involves breaking down rocks into smaller pieces through mechanisms like freeze-thaw cycles and abrasion. Chemical weathering involves the breakdown of rocks through processes like hydration, oxidation, and dissolution, which help to further break down rocks into soil particles.
Basalt not 100% but most of it. About 10% is other rocks. I hope that helps

No. Most rocks and earth are not directly from volcanoes.

A volcanologist most directly studies the geosphere, which encompasses the Earth's solid components, including rocks, minerals, and geological processes. Their focus is primarily on volcanic activity, the formation of volcanoes, and the associated geological phenomena. Additionally, they may also consider interactions with the atmosphere and hydrosphere when studying the effects of volcanic eruptions.
Metamorphic rocks are formed from existing rocks that undergo extreme heat and pressure, causing them to recrystallize without melting. Most other rocks, like igneous and sedimentary rocks, are formed through processes such as cooling from molten material or compaction and cementation of sediments.
No, the most important agent of chemical weathering is typically water. Water helps break down rocks through processes like hydration, hydrolysis, and oxidation. Abrasion, which is the physical wearing down of rocks by friction and impact, is an example of mechanical weathering rather than chemical weathering.
Most mineral resources originate from geological processes such as volcanic activity, weathering of rocks, and hydrothermal processes. These processes contribute to the formation and concentration of minerals in the Earth's crust, where they are eventually mined for various industrial purposes.
Although sedimentary rocks form in a variety of processes, the first process that would occur in the formation of the most common sedimentary rocks would be that of weathering, which is the breakdown of rocks into smaller pieces through chemical or mechanical means by nature.
A geologist, particularly one specializing in volcanic activity or petrology, is most likely to study the cooling of lava after a volcanic eruption. They analyze the physical and chemical properties of lava, its crystallization processes, and how it interacts with the environment as it cools. Their research helps in understanding volcanic processes and the formation of igneous rocks.
Because metamorphic rocks from very deep underground, they have to be brought to the surface by some geologic processes before they are exposed. There are many processes that could do this, but the most common is a mountain building event. Mountainous areas often have very large areas of exposed metamorphic rocks.
