River Basins & Water Distribution
This is the largest reservoir of water on Earth.
What are the Oceans ?
Cold, salty water becomes more dense and does this.
What is sinks?
A pH below 7 means water is becoming more this.
What is acidic?
This property allows water to move up a thin tube or plant stem.
What is Capillary Action?
This greenhouse gas is most connected to climate change.
What is Carbon Dioxide?
These frozen freshwater sources hold much of Earth’s freshwater.
What are Glaciers and ice caps ?
Warm water is usually less dense and does this.
What is Rises?
Too many nitrates in water are often caused by this farming material.
What is fertilizer?
This property allows insects or small objects to rest on the surface of water.
What is Surface Tension?
Water helps moderate temperature because it has this type of specific heat.
What is High Specific Heat?
If pollution enters a stream, people downstream in the same river basin should be concerned because water flows through the same drainage area.
What is a river basin?
Earth’s rotation causes currents to curve right in this hemisphere.
What is the Northern Hemisphere?
Treating wastewater before releasing it helps protect this.
What is Water Quality?
Water expands when it freezes, which can cause a full plastic bottle to do this.
What is Break?
Urban areas often have higher temperatures because they have low albedo (reflective power) and high this.
What is Heat absorption?
Water found underground in soil and rock layers is called this.
What is an Groundwater?
This combination increases water density and causes it to sink, helping drive deep ocean currents.
What are low temperature and high salinity? ?
A lake’s pH drops from 6 to 4 over time. Predict the impact on fish populations.
What is increased fish stress, slower growth, or death due to acidic conditions?
This property explains why water dissolves many substances due to its uneven charge distribution.
What is polarity?
This surface condition leads to the highest temperatures due to low albedo and high heat absorption.
What are urban areas?
Put these in order from greatest to least abundance on Earth: oceans, groundwater, glaciers/ice caps, surface water.
What is Oceans → Glaciers/Ice Caps → Groundwater → Surface Water ?
In polar regions, less solar energy causes temperature to ___, density to ___, and water to ___.
What is Decrease, increase, sink ?
Which TWO actions are most effective for reducing nitrate pollution in water systems?
What are preventing untreated sewage and reducing fertilizer runoff?
When water freezes, it expands due to this molecular behavior, making ice less dense than liquid water.
What is hydrogen bonding causing molecules to spread apart?
Explain why oceans play a major role in regulating global climate patterns.
What is oceans absorb, store, and redistribute heat through currents, influencing weather and climate globally?
