What is the equator
An imaginary line dividing the earth into the Northern and Southern hemispheres
The elements before the arrows in a chemical equation
Reactants
What region is the United States in
North America
What are the big numbers at the front of an element in a chemical equation
Coefficients
What is energy
The capacity to do work
What is wind and how does it move
Air in motion, moving horizontally from high to low pressure
What are the small numbers placed slightly below the elements in a chemical equation
Subscripts
Define regional climate
Long-term, average weather patterns for a specific area
The elements after the arrows in a chemical equation
Products
What is the difference between kinetic energy and potential energy
Kinetic- energy of motion
Potential- Stored energy
Why does wind blow?
warm, low-pressure air rises and cool, high-pressure air sinks causing air to flow to balance it out
What does it mean when two elements are in parentheses in a chemical equation
The elements are bonded
What does the tilt of the Earth affect
Earth's tilts affects the seasons
Law of Conservation with atoms
Atoms can not be created of destroyed
What is the difference between mass and weight
mass is how much matter, while weight is how hard gravity pulls on that matter.
How will climate change affect air circulation
The air above oceans will not be as cool during the day and there will be less air circulation between water and land
When is a chemical equation balanced
When there are the same number of atoms for each element on both sides of the equation
Ocean circulation is a result of what
Wind pushing on the surface of the water
How do you simplify a chemical equation
Divide the coefficients
Name the 8 planets in our solar system
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune
Atmospheric circulation is a driven by what?
Uneven solar (sun) heating that takes heat from the equator and pushes it towards towards the poles
What values can change on a chemical equation to balance it
Only the coefficients (subscripts never change)
Describe the Coriolis effect ?
Because of the Earth's spins, air or water moving long distances seem to curve instead of going straight. Curving right in the Northern Hemisphere and left in the Southern Hemisphere.
What happens to the atomic mass when iron and oxygen combine
Their atomic mass will equal that of iron oxide
Why is ice slippery
because of a super-thin layer of liquid water on its surface, created by friction, pressure, or surface melting
