What is the hydrological cycle?

The continuous movement of water within the Earth and atmosphere.

What are the main storages in the hydrological cycle?

Oceans, ice caps and glaciers, groundwater, lakes and rivers, and the atmosphere.

What percentage of Earth's water is freshwater?

Only 2.5% of Earth's water is freshwater.

What is the primary source of ocean currents?

Surface currents are driven by wind patterns and the Earth's rotation.

What is thermohaline circulation?

A deep ocean current driven by differences in water density due to temperature and salinity.

How does urbanization affect the hydrological cycle?

It increases surface runoff and decreases infiltration due to impermeable surfaces.

What are the two types of water scarcity?

Economic water scarcity and physical water scarcity.

What is desalination?

The process of converting seawater to freshwater.

What is aquaculture?

The farming of aquatic organisms to meet increasing demand for aquatic food resources.

What is eutrophication?

The excessive enrichment of water bodies with nutrients, leading to rapid growth of algae.

What are the key parameters for measuring water quality?

Dissolved Oxygen, Biochemical Oxygen Demand, pH, Turbidity, Nutrient Levels, and Bacterial Counts.

What is the impact of eutrophication on aquatic ecosystems?

It leads to oxygen depletion, fish kills, loss of biodiversity, and reduced water quality.

What are catch quotas?

Limits on the amount of fish that can be caught to manage fish populations.

What is the role of marine protected areas (MPAs)?

Designating areas where fishing is restricted or prohibited to protect marine ecosystems.

What is the significance of primary productivity in aquatic ecosystems?

It is the rate at which energy is converted to organic substances by photosynthetic organisms.

What are best management practices in agriculture for water pollution control?

Precision fertilizer application, buffer strips along waterways, and contour plowing to reduce runoff.
