What is Primary Succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, such as after a volcanic eruption or glacier retreat.

Front

What is Secondary Succession?

Back

Secondary succession is the process of ecological change that occurs in an area where a disturbance has destroyed an existing community but left the soil intact.

Front

What are Climax Communities?

Back

Climax communities are stable, mature ecological communities that undergo little change in species composition, typically reached after a series of successional stages.

Front

What is Sedimentary Rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles, often found in layers.

Front

What is Igneous Rock?

Back

Igneous rock is formed from the solidification of molten rock (magma or lava) and can be classified as intrusive or extrusive.

Front

What is Metamorphic Rock?

Back

Metamorphic rock is formed from the alteration of existing rock types through heat, pressure, and chemically active fluids.

Front

What is Ecological Succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of stages leading to a stable community.
