Warm air masses and cool air masses collide the denser cool air sinks under the less dense warm air
Plates moving away from each other divergent
Plates moving toward each other convergent
Plates sliding alongside each other transform
Evidence of continental drift fossils, glaciers in warm areas, and rocks
Evidence of sea floor spreading ages of rocks, magnetic fields, life-forms (giant clams, mussels, tube worms)
Type of fault caused in the rock when plates slide strike-slip fault
What causes wind and ocean currents? the unequal heating of the Earth/atmosphere
The cycle of heating, rising, cooling, and sinking convection currents
High speed, high altitude winds jet streams
Part of North Atlantic gyre that brings warm water along US east coast towards Europe Gulf Stream
Unusual warming of waters off the coast of Peru due to weak trade winds El Nino
To use a smaller amount of material reduce
When waste is separated by different material types recycle
Symbols used to indicate the amount of cloud cover of an area empty circle = clear / quarter filled circle = somewhat cloudy / half filled circle = partly cloudy / filled circle = overcast
Renewable resources resources replaced quickly in nature

Solar wind consists of particles from the sun's corona that escape
Nicholas Copernicus (3) sun centered the solar system (heliocentric) / distance of the planets from the sun directly relates to the size of the planets orbit / daily movement of stars and planets due to Earth's rotation
Galileo Galilei (4) invented telescope in 1609; 3x sight, then 20x / discovered 4 satellites of Jupiter / discovered sunspots / observed that Venus went through the same phases as the moon
Johannes Kepler (1605) (2) orbits are elliptical (circular) around offset sun / planets travel at different speeds
Parts of the sun innermost = core / second layer = radiative zone / third layer = convection zone / photosphere / chromosphere / corona
Features of the sun (4) sunspots = areas appearing dark because they are cooling / prominences = huge, arching columns of gas erupting from sun / solar flares = gases near sunspot suddenly brighten and shoot outward from sun's corona / CME's = coronal mass ejection
