What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation, involving igneous, sedimentary, and metamorphic rocks.

What causes sedimentary rocks to form?

Back

Sedimentary rocks form from the accumulation and compaction of sediments, which can include minerals, organic matter, and fragments of other rocks.

Front

What is metamorphism?

Back

Metamorphism is the process by which existing rocks are transformed into metamorphic rocks through heat, pressure, and chemical processes.

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other, causing geological activity such as earthquakes and volcanic eruptions.

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks into smaller pieces, while erosion is the movement of those pieces from one location to another.

How do fossils form?

Back

Fossils form when organisms are buried by sediment, which hardens over time, preserving the shape and structure of the organism.

What is the significance of plate tectonics?

Back

Plate tectonics explains the movement of continents, the formation of mountains, earthquakes, and volcanic activity.

What is the role of pressure in the formation of metamorphic rocks?

Back

Increased pressure can cause existing rocks to change their structure and mineral composition, resulting in metamorphic rocks.

Front

What is the process of cementation?

Back

Cementation is the process where dissolved minerals precipitate and bind sediment particles together, forming solid rock.

What are igneous rocks?

Back

Igneous rocks are formed from the cooling and solidification of molten rock (magma or lava).
