What role does water play in the ways the suns energy is transferred to the earth |
Water has a high SHC and absorbs a lot of heat without changing its temp. |
|
|
Absolute humidity |
the actual amount of water vapor in the air shown as grams of water per cubic kilogram of air |
|
|
Relative humidity |
Is the percentage of water vapor in the air compared to the actual amount that could be carried by the air in its saturated state. |
|
|
The temperature outside is -22 and the relative humidity is 90%. If the temp in the house is 18, what is the relative humidity in the house -22 = 0.66 g/kg 18+ 13.3 g/kg |
.9*.66= 0.59g .59/13.2*100%=4.5% |
|
|
What kind of clouds are associated with a warm front Hint: CCANS |
Cirrus- whispy hair like, Cirrostratus- whispy layers, Altostratus-mid layers, Nimbostratus rainbearing layers, stratus- rain clouds (layers) |
|
|
Weather associated with a cold front |
moves quickly causing, cumulus clouds to form, cumulonimbus thunderheads, precipitation can fall suddenly and intensely, thunderstorms are common and lightning, but this is short and the weather clears once it has passed |
|
|
Cumulus clouds |
can be found at all levels, may cause precipitation, cotton like to thunderhead |
|
|
Stratus clouds |
can be found at all levels, usually come before rain especially in a warm from, flat, layered
|
|
|
Nimbus clouds |
tells you there will be precipitation, usually paired with lower level clouds |

What classifies a chemical change |
1. a permanent change of color 2. formation of precipitate 3. formation of gas and or energy change 4. an energy change (heat or light) 5. the original substance disappears |
|
|
What are the 3 types of changes of matter |
chemical, physical, nuclear |
|
|
what are the 5 trends of the periodic table? |
1. Atomic number increases as you go up 2. Atomic mass increases as you go up 3. Fr (Francium) to F (Fluorine) most to least metallic 4.Atomic radius, left to right decreases, top to bottom- increases 5. ionization energy - left to right increases, top to bottom - decreases |

|
|
Who discovered neutrons |
James Chadwick |
|
|
When did Mendeleev publish his table? |
1869 |
|
|
When was the first noble gas discovered? |
1894, by William Ramsey and Lord Rayleigh |
|
|
pH |
a measure of how acidic/basic something is |
|
|
What is the solar constant? |
The solar constant is the amount of energy the enters the earths outer atmosphere at a rate of 1367 J/m2s
|
|
|
Describe the variety of ways the sun transfers energy to the earth.
|
Electromagnetic waves have a variety of different wavelengths, from gamma rays to radio waves and visible light. Radiation, convection and conduction also play a part
|
|
|
Gyres |
a large system of rotating currents caused by the Coriolis effect
They bring warm water to the poles and cold water to the equator. |
|
|
Anticlones |
the centers of high pressure system |
|
|
Cyclones |
the centers of low pressure system
|
|
|
High pressure system |
when air is pushed down to earth and, since the air air is moving down, there are no clouds |
|
|
Low pressure system |
the air is moving up meaning that there will be condensation |
|
|
Thermo-hayline circulation |
The thermohaline circulation supplies heat to the polar regions, |
|
|
Characteristics of acids |
they taste sour and turn litmus paper red. They react with metals to give off hydrogen |
|
|
Characteristics of bases |

|
|
|
What are 5 types of chemical equations |
Synthesis reactions, single displacement, decomposition reaction, double displacement, combustion reaction |

|
What creates wind? |
the unequal heating of earths surface generates pressure differences, which moves warm air up and cooler air to the equator
|
|
|
Polar easterlies |
are winds that blow from thepolar high toward the subpolar low. These windsare not constant like the trade winds. |
|
|
Westerlies |
are the dominant west-to-east motionof the atmosphere that characterizes the regionson the pole-ward side of the subtropical highs |
|
|
Trade winds |
are two belts of winds that blowalmost constantly from easterly directions andare located on the north and south sides of thesubtropical highs |

|
|
Where is the jet stream found |
troposphere |
|
|
Why is the jet stream strongest in the winter? |
because the difference between the cold polar and warm tropical air is the largest, and both air masses push on the jet stream |
|
|
Jet Stream characteristics |
A jet stream is an area of strong winds ranging from 120-250 mph that can be thousands of miles long, a couple of hundred miles across and a few miles deep. Jet streams usually sit at the boundary between thetroposphere and the stratosphere |
