Answer 1

Sedimentary cycles have their reservoirs in the Earth’s crust or rocks. Nutrient elements are found in the sediments of the Earth. Elements such as sulphur, phosphorus, potassium, and calcium have sedimentary cycles.

Sedimentary cycles are very slow. They take a long time to complete their circulation and are considered as less perfect cycles. This is because during recycling, nutrient elements may get locked in the reservoir pool, thereby taking a very long tim

Answer 2

Answer:

• Sedimentary cycles have reservoirs in the crust of earth or rocks. Nutrient elements such as phosphorus, sulphur, potassium and calcium are present in the sediments of the earth.
• These sedimentary cycles are unhurried, and slow.
• It takes a long time to complete their circulation and are deemed to be less perfect cycles.
• It is because when recycling, the nutrient elements may get sealed in the reservoir pool taking a long time to come out and continue circulation.
• Hence, they typically go out of circulation for a long period of time.
