Front

What major environmental issue occurred due to the diversion of water for cotton in the Aral Sea?

Back

The diversion of water for cotton in the Aral Sea led to a 90% reduction in water levels, resulting in salt flats and air pollution.

Front

What is nutrient pollution and its impact on watersheds?

Back

Nutrient pollution, often from sewage, can lead to algal blooms in watersheds, which can deplete oxygen and harm aquatic life.

Front

What is drip irrigation and its efficiency?

Back

Drip irrigation is an irrigation method that delivers water directly to the roots of plants through a system of tubing, and it is 95% efficient but can be time-consuming and costly.

Front

What is the consequence of California's aqueduct systems for water management?

Back

California's aqueduct systems, while necessary for water diversion, can lead to significant water evaporation.

Front

Define spray irrigation.

Back

Spray irrigation is a method of applying water to crops through a system of pipes and pumps that spray water over the plants, similar to rainfall.

Front

What is the Ogallala Aquifer and its significance?

Front

Explain the concept of water conservation.

Back

Water conservation involves strategies and activities to manage fresh water resources sustainably, reducing water waste and ensuring availability for future generations.

Front

What are the effects of algal blooms on aquatic ecosystems?

Back

Algal blooms can lead to hypoxia (low oxygen levels), harming fish and other aquatic organisms, and can produce toxins that affect water quality.

Front

What is the role of aqueducts in water distribution?

Back

Aqueducts are man-made channels or pipelines used to transport water from one location to another, often over long distances.
