Spheres
Where most of the water on Earth can be found
what is the hydrosphere?
the most abundant gas in our atmosphere at 78%
What is nitrogen
increase in volume that results from increase in temperature
thermal expansion
the curving of the path of a moving object from an otherwise straight path
Coriolis effect
The gulf stream is the strongest type of this current
what is a surface current
all of the matter, energy, and processes within Earth's boundary
what is the Earth's systems
the measure of force with which air molecules push on an area of a surface
what is air pressure
energy that is transferred between two objects
heat
winds in the northern hemisphere curve in this direction
what is the right
3 factors that affect surface currents
continental deflection, Coriolis effect and global winds
is the most dense layer of the Earth
what is the core?
a mountain climber needs an oxygen supply at high altitudes
there are much fewer molecules of oxygen
transfer of energy as electromagnetic waves such as the sun
radiation
these winds blow between 30 and 60 degrees in both hemispheres
what are the westerlies
Southern Hemisphere global surface current flow in this direction
what is counterclockwise
this is the percentage of water covering the Earth
What is 71%? FYI 97% is salt
the 4 layers of the atmosphere
thermosphere, mesosphere, stratosphere and troposphere
transfer of energy due to movement of matter such as lava lamp
convection
a narrow belt of high speed winds that blow from east to west
what is the jet stream
movement of water that results from density difference
what are convection currents
Most of the Earth's energy comes from this
what is the sun?
these are two examples of greenhouse gases
what are water vapor and carbon dioxide
transfer of energy through direct contact such as holding a pot holder
what is conduction
during the day the high pressure breeze comes from __________ in the mountains
valley
Upwelling water contains
nutrient rich such as iron and nitrate
