Coal can weather and erode through physical and chemical processes. Physical weathering occurs when coal is exposed to temperature changes, leading to cracking and fragmentation. Chemical weathering happens when coal reacts with moisture and oxygen, resulting in the breakdown of its organic compounds. Over time, these processes can lead to the disintegration of coal deposits, especially in areas with significant environmental exposure.

What is after lava but before boulder?

After lava cools down and solidifies, it forms rocks. These rocks can then weather and erode into small fragments called boulders.


Does heat and metamorphism cause rock to weather and erode?

Heat and metamorphism do not directly cause rocks to weather and erode. Weathering and erosion are primarily driven by physical processes like water, wind, and ice acting on rocks at the Earth's surface. However, heat and metamorphism can alter the mineral and chemical composition of rocks, potentially making them more susceptible to weathering and erosion over time.

What can affect the rate at whick a rock weathers?

Rocks weather due to physical changes. They can also weather as a result of chemical processes. Things that can affect the rate at which a rock weathers includes weather conditions. Rocks can decompose due to wind and water. The more intense the weather conditions, the more progressive the weathering process will be.


What type of rocks weather and erode to form sedimentary rocks?

Igneous, metamorphic, and existing sedimentary rocks can weather and erode to form sedimentary rocks. Igneous and metamorphic rocks can break down into sediments through processes like weathering and erosion, which then may accumulate and lithify into sedimentary rocks. Existing sedimentary rocks can also be reworked and lithified to form new sedimentary rocks through processes like compaction and cementation.
