| Twice a year when the length of day and night are approximately equal all over the planet for an instance is an ___________ | equinox |
| What is the date for the fall equinox | September 22 or 23 |
| What is the date for the spring equinox | March 20 |
| Twice each year the sun reaches it's greatest angular distance from the equator, an event known as __________ | solstice |

| what is the date for the winter solstice | December 21 or 22 |
| what is the most obvious evidence of the sun's influence | the seasons |

| The latitude zone closest to the equator is called the | tropics |
| in which latitude is the sunlight nearly direct half of each year creating seasonal changes | middle latitude |
| regions that have neither the constant warmth of the tropics nor the extreme cold of the poles are called | temperate zones |
| regions that receive only small amounts of sunlight in the winter are called _______ regions | polar |

| what are the 5 basic elements of weather | temperature, atmospheric pressure, wind, precipitation, and humidity |
| an indication of the amount of thermal energy in the air is | temperature |
| the weight of gases in the atmosphere on a surface area | atmospheric pressure |
| What are some factors that affect atmospheric pressure | air temperature and moisture |
| the movement of air caused by the heating and cooling of air masses | wind |
| a large area of moving air with a similar temperature is called an | air mass |
| why don't we feel the earth moving | The Coriolis Effect |
| which area has the most powerful prevailing winds | the hot tropics |
| The prevailing winds that blow over middle latitudes are called the | westerlies |
| most precipitation is in the form of | rain |
| the process of evaporation, condensation, and precipitation is called the | hydrologic cycle |
| the measure of the amount of moisture in a given volume of air at a given temperature is called | humidity |
| the point in which water vapor begins condensation is called | the dew point |
| the slowest ocean currents are called | drifts |
| which 3 situations cause a humid air mass to cool and produce precipitation | the presence of mountains, the meeting of cold and warm air masses, the rise of warm air over a hot surface (convection) |
