Salt water, • then frozen ice, • groundwater, • surface water, • water vapor
Is Earth’s water steadily increasing, decreasing, or staying in balance?
What process takes place when liquid water absorbs enough energy to change into water vapor?
What is the process where four forms of water fall from clouds to Earth’s surface?
Fresh water enters the ocean (ex. from rivers and rain); but water also evaporates from the ocean, leaving the salt behind.
As you descend in the ocean, through the water column, how do the conditions change? (include temperature, light, pressure, and density)
First, continental shelf, continental slope, abyssal plain • Then possibly seamounts and volcanic islands, midocean ridge, trenches
How do surface currents (ex. Gulf Stream, California Current, EAC) affect coastal climates?
Surface currents warm or cool the air above affecting temperatures and the climate of nearby places.
High tide is when water reaches its highest point; low tide is when water reaches its lowest point. High tides occur about every 12 hours; low tides occur about every 12 hours.
Spring tides: full moon and new moon phases (all in a straight line); sun-Earth-moon and sun-moon-Earth
Neap tides: 1st quarter and 3rd quarter phases (lined up at 90 degree angles)
Nitrogen 78%, • Oxygen 21%, • other 1%
As altitude increases, air pressure ____________ and air density ____________.
Caused by differences in pressure, due to unequal heating of land vs. water
