What is an aquifer?

Back

An aquifer is a permeable layer of rock or soil that holds a large amount of water in the saturated zone.

Front

What is a negative human impact on ocean systems?

Back

Fertilizers from farms runoff into rivers and create dead zones at the mouth of rivers in our world's oceans.

Front

How do oceans regulate the climate?

Back

Oceans regulate the climate by moving water through currents that heat or cool the atmosphere around the world.

Front

What are the potential sources of waste that can end up in ocean systems?

Back

Wastes produced by agriculture, households, industry, mining, and other human activities can all end up in ocean systems.

Front

What is a positive human impact on ocean systems?

Back

Recycling trash helps prevent plastic and other unwanted trash from entering our ocean systems.

Front

Define 'dead zones' in the context of ocean systems.

Back

Dead zones are areas in oceans or large lakes where the oxygen level is so low that marine life cannot survive, often caused by nutrient pollution.

Front

What role do ocean currents play in climate regulation?

Back

Ocean currents distribute heat and cold across the planet, influencing weather patterns and climate.

Front

What is nutrient pollution and how does it affect ocean systems?

Back

Nutrient pollution occurs when excess fertilizers and waste runoff into water bodies, leading to algal blooms and dead zones.

Front

What are some human activities that contribute to ocean pollution?

Back

Agriculture, industrial processes, waste disposal, and urban runoff are human activities that contribute to ocean pollution.

Front

Explain the concept of 'sustainable practices' in relation to ocean health.

Back

Sustainable practices involve using resources in a way that maintains ecosystem health and prevents degradation, such as reducing plastic use and promoting recycling.
