Water Properties
What is the chemical formula for water?
H20
What process in the water cycle involves water vapor cooling and turning into liquid droplets?
Condensation
What is the path a stream follows?
Channel
What do we call underground layers of rock or sediment that hold water?
Aquifers
What causes surface currents?
Wind
What is the process called when water changes from a liquid to a gas?
Evaporation
What powers the water cycle?
Sun
What do we call the area of land where all water drains to a common point, like a river or lake?
Watershed
What is the upper level of groundwater called?
Water Table
What is the rise of cold, nutrient-rich water from deep in the ocean?
Upwelling
Why is water considered a "universal solvent"?
Because it dissolves many substances
What is precipitation?
Any form of water that falls from the sky, such as rain, snow, or sleet
What is the name of the process by which rivers carve through the land and change the landscape over time?
Erosion
What is the water that collects on the surface of the Earth, such as in rivers, lakes, ponds, and streams
Surface Water
What is the difference between surface currents and deep ocean currents?
Surface currents are driven by wind, while deep ocean currents are driven by differences in water density
What is the phenomenon called when water molecules stick to other surfaces?
Adhesion
How does transpiration contribute to the water cycle?
Plants release water into the atmosphere
What term is used to describe water that moves over the land surface and into bodies of water after rainfall?
Runoff
What is the process called when groundwater is pumped to the surface for human use?
Well Drilling
What water is more dense? Fresh or Salty?
Salty
What is called when water sticks to itself causing droplets on surfaces?
Cohesion
What is sublimation?
Sublimation is when ice or snow changes directly into water vapor without becoming liquid first.
What is a smaller stream or river that flows into a larger river, contributing additional water, sediment, and nutrients to the main river system
Tributary
What is water that is stored beneath the Earth's surface in soil and rock formations?
Groundwater
What is it called when surface currents collide or combine with deep currents creating a continuous cycle?
Convection Currents
