Temperature and Pressure

When molecules get hotter…

molecules expand and take up more space

Moving faster…

expands

moving slower…

shrinks

Temperature

degrees of hotness

Heat

quantity of hotness

As volume increases, pressure…

decreases

Conduction

must be touching, ex: flame touching paper

Radiation

electromagnetic waves, ex: sun, microwave

Convection

gas or liquid, ex: water boiling on stove

What causes shifting of tectonic plates?

currents against crust

Convergent boundary

makes islands, super low sea level

Divergent boundary

new seafloor, increase in elevation

Percent error formula

(actual value - measured value) / actual value x 100

Density formula

D = m / v

Troposphere

weather occurs, lowest, first layer

Stratosphere

ozone, jet planes fly in to avoid weather, 2nd layer

Mesosphere

very low density of gases, meteors burn up, 3rd layer

Thermosphere

very few air particles, still cold due to density, 4th layer

Exosphere

air particles escape to space, satelites orbit, last layer

Greenhouse effect

atmosphere holds in heat around the earth

Climate

what you expect/predict

Weather

what actually happens
