This tool
Mercury Barometer
Two or more different atoms bonded together
Compound
This temperature of air is most dense and will sink
Cold air
What the conditions are like in a specific area over a long period of time.
Climate
This kind of pressure happens when cool air sinks.

Most of Somalia and much of other African countries are this type of climate.
Desert
This type of front is formed when a colder air mass moves toward a warmer air mass.
Cold front
This is how a warm front is shown on a weather map.
red line with half circles
Tool used to measure how fast molecules are moving
Thermometer
O3 is an example of this type of bond
Molecule
Rain, Hail, Snow, and Sleet are examples of this.
Precipitation
In NYC, the weather is coldest in this season and we typically see snow.
Winter
This is a type of front happens when a warm air mass slowly moves over a cold air mass.
warm front
This is shown as a red and blue line with half-circles AND spikes.
