Water Cycle
Name the process where liquid changes to gas
Evaporation
What is the chemical formula for water
H2O
What is salinity, and what is its unit?
How much salt is dissolved in a substance. ppt (parts per thousand)
In what layer of the atmosphere does weather occur?
Troposphere
Direct transfer of heat between matter (two things, objects, substances)
In order for condensation to occur, what needs to be present
A surface like glass or dust to stick to.
What is the difference between cohesion and adhesion?
Cohesion: water molecules attracted to and sticking to one another
Adhesion: water molecules attracted to and sticking to other surfaces
What is known as the 'global conveyor belt?'
Thermohaline Circulation
What is the role of Nitrogen, when supporting life on Earth
Help living things make proteins
What instrument measures air pressure
barometer
Name the process where water evaporates from plants
Transpirtation
What type of bond forms water
Covalent Bond
Thermosphere and Mesosphere
Name the four major Greenhouse Gases
Nitrous Oxide, Water Vapor, Methane, Carbon Dioxide?
What processes of the water cycle are driven by gravity?
Precipitation, Runoff, Infiltration
Name this term: the ability of liquid to flow through narrow spaces against gravity due to cohesion and adhesion.
Capillary Action
Which is more dense?
Cold, salty water or Warm, less salty water
Cold, salty water
How do clouds affect Earth's temperature during the day and at night
Clouds reflect heat/sunlight during the day and absorb heat/sunlight at night
In order for air pressure to be recorded, what has to happen first
It has to be converted to sea level
Water stored in between the rocks that eventually flows back into bodies of water. It is created by infiltration.
Why does water freezes from top to bottom?
Ice is less dense than water, and it insulates the water (aquatic life) below
Which way does the currents curve in the Northern and Southern Hemisphere
Northern Hemisphere: right
Southern Hemisphere: left
What is the boundary in between each layer called?
Pauses
The Greenhouse effect prevents heat loss from what process?
Convection
