The Rock Cycle – Diagram and Explanation - Science Notes and …
2023年8月22日 · The rock cycle is the natural, continuous process that forms, breaks down, and reforms rock through geological, chemical, and physical processes. Through the cycle, rocks convert between igneous, metamorphic, and sedimentary forms.
Rock cycle - Wikipedia
The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions.

2023年4月23日 · Sedimentary Rock Cycle Process. Rocks exposed to the atmosphere are variably unstable and subject to weathering and erosion. Abrasion and erosion break down the original rock into smaller pieces and remove dissolved materials. This shredded material accumulates and is embedded by additional material.
3.3: The Rock Cycle - Geosciences LibreTexts
Sedimentary rocks form by the compaction and cementing together of sediments, broken pieces of rock-like gravel, sand, silt, or clay (figure 5). Those sediments can be formed from the weathering and erosion of preexisting rocks.

2020年11月2日 · The rock cycle is the process that describes the gradual transformation between the three main types of rocks: sedimentary, metamorphic, and igneous. It is occurring continuously in nature through geologic time.
The Rock Cycle - Education
2023年12月13日 · There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.
Sedimentary rocks are formed by the lithification of inorganic and/or organic sediments, or as chemical precipitates. There are two types of sedimentary rocks: Clastic and Chemical
5.1: The Rock Cycle - Geosciences LibreTexts
2024年4月11日 · Rock is weathered, both physically (breaking into smaller pieces) and chemically (by alteration of the minerals). These weathering products—mostly small rock and mineral fragments—are eroded, transported, and then deposited as sediments.
The rock cycle - The Earth and atmosphere - KS3 Chemistry - BBC
Sedimentary rocks can change into metamorphic rocks due to heat and pressure from the movements of the Earth. Those metamorphic rocks can be weathered, eroded, and the pieces transported away.
5.4: Sediments and Sedimentary Rocks - Geosciences LibreTexts
2024年4月11日 · The cycle begins with the exposure of pre-existing rock to the “agents” of weathering and erosion. Weathering involves exposure of pre-existing rock to Earth’s surface weather conditions. These “agents” include wind, water and ice — plus gravity.
