| Globe | A spherical scale model of Earth |
| Latitude | Geographic coordinate that specifies the north or south of the Equator |
| Longitude | Distance measured in degrees east or west from an imaginary line passing through Greenwich, England |
| Hemisphere | A half of earth, usually divided into northern and southern halves by the equator, or into western and eastern halves by an imaginary line passing through the poles |
| Weather | The state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, and precipitation |
| Land breeze | a breeze blowing usually at night toward the sea from the more rapidly cooling land |
| Sea breeze | a cooling breeze blowing generally in the daytime inland from the sea |
| Air Pressure | The weight of the air pushing on everything around it |
| Barometer | A weather instrument that measures air pressure |
| Low Pressure | A mass of warm, rising, moist air that brings stormy weather like rain, snow and strong winds. Caused by a drop in air pressure followed by colder weather. |
| High Pressure | |
| El Nino | a warming of the ocean surface, or above-average sea surface temperatures, in the central and eastern tropical Pacific Ocean. |
| Climate | the average weather conditions in an area over a long period |
| Atmosphere | The envelope of gasses surrounding the earth |
| Cirrus | White wispy clouds that form at high altitudes and are always made of ice crystals. |

| air mass | a large “bubble” of air that has about the same temperature and humidity throughout it |
| La Nina/El Nino | unusual warming or cooling of the seawater in the Pacific Ocean |
| Temperature | the average speed of the particles in a substance |
| air pressure | the weight of the air pushing on everything around it |
| Humidity | water vapor in the air |
| Thermometer | a tool that measures temperature |
| Barometer | a weather instrument that measures air pressure |
| Anemometer | a weather instrument that measures wind speed |
| wind vane | a weather instrument that shows the direction the wind is coming from |
| rain gauge | a weather instrument that measures rainfall |
| front | a place where one air mass meets and pushes aside another air mass |
