Water Pollution

Front

What is an aquifer?

Back

An aquifer is a geological formation that can store and transmit water, typically found underground.

Front

What are dead zones in water bodies?

Back

Dead zones are areas in water bodies where oxygen levels are so low that marine life cannot survive, often caused by nutrient pollution.

Front

What is the primary cause of most water pollution?

Back

Most water pollution is primarily caused by human activities, such as industrial discharge, agricultural runoff, and urban waste.

Front

What are the main parts of the water cycle?

Back

The main parts of the water cycle include condensation, evaporation, and precipitation.

Front

What is eutrophication?

Back

Eutrophication is the process by which water bodies become enriched with nutrients (like nitrogen and phosphorus), leading to excessive growth of algae and depletion of oxygen.

Front

What is thermal pollution?

Back

Thermal pollution refers to the degradation of water quality by any process that changes ambient water temperature, often due to industrial discharges.

Front

What is the role of evaporation in the water cycle?

Back

Evaporation is the process where water changes from liquid to vapor, contributing to the movement of water into the atmosphere.

Front

What is the impact of fertilizer runoff on water bodies?

Back

Fertilizer runoff can lead to nutrient pollution, causing eutrophication and harmful algal blooms in water bodies.

Front

What is the significance of low oxygen concentrations in water?

Back

Low oxygen concentrations in water can lead to dead zones, where aquatic life cannot survive due to insufficient oxygen.

Front

What is the difference between point source and non-point source pollution?

Back

Point source pollution comes from a single, identifiable source (like a factory), while non-point source pollution comes from diffuse sources (like agricultural runoff).
