Ocean
Brings cold, nutrient-rich water to the surface and boosts marine life and fishing industries.
Upwelling
Comes from a single, identifiable source (e.g., pipe, factory).
Point- Source Pollution
All river basins lead to?
Oceans or Larger bodies of Water
Monitoring water quality is to ensure water is safe to drink. What is another term used to describe this type of water?
Potable
Everyone lives in a watershed, what watershed do you live in?
Catawba (Charlotte) or Rocky River (Concord) or Yadkin (Concord)
Currents are influenced by?
Temperature and Salinity
Comes from many different sources (e.g., runoff from roads, farms, and lawns)
Non-Point Source Pollution
A large watershed that drains into a major river.
River Basin
A measure of how clear or cloudy water is?
Turbidity
In the global ocean conveyor belt, this location's current plays a crucial role in transporting warm water northward from this location, influencing climate patterns in the North.
Equator or Gulf Stream
What are two types of Ocean Currents?
Surface and Deep Currents
After a heavy rain, fertilizers from many lawns wash into a nearby lake, causing algae to grow out of control. What type of pollution is this?
Non-Point Source Pollution
All the land where water drains to a common point, often making up part of a river basin.
Watershed
What is the pH scale used to measure?
Determines if a substance is an acid or base.
What does water with high turbidity do?
Blocks sunlight, affects plant growth and fish health, indicates pollution
These large systems of circular ocean currents, caused by the Coriolis effect and wind patterns, are found in each major ocean.
Gyres
This happens when too much nutrients (nitrogen & phosphorus) enter a body of water.
Eutrophication
Areas where fresh and saltwater mix
Estuaries
Dissolved Oxygen is best stored in what type of water?
Cold, deep water with low salinity levels
Eutrophication causes?
Algae growth, Low Oxygen, and Decrease in marine life
This term describes the worldwide system of surface and deep ocean currents that circulates heat and nutrients around the globe.
Global Ocean Conveyor Belt
A broken sewage pipe is leaking waste into a river at a specific location. What type of pollution is this?
Point Source Pollution
What is a Drainage Divide?
a high point of land, like a ridge or mountain, that separates water flow.
Two lakes are tested. Lake A has a pH of 6, low turbidity, and high dissolved oxygen. Lake B has a pH of 4, high turbidity, and low oxygen. Which lake has better water quality and why?
Lake A because it is closer to neutral pH, is clearer, and has more oxygen for aquatic life?
Only about 2.5% of Earth’s water is fresh. Most of that is located where?
Ice (glaciers and polar ice caps)
