| A | B |
|---|
| Density= | mass (m) /volume (v) |
| Warm (air, water, magma) | rises because it is less dense |
| Cold air | sinks |
| Latitude | lines run east and west |
| Longitude | lines run north and south |
| The closer the Contour Lines | the steeper the slope of the land |
| Countour lines form V's point | downstream of rivers |
| Water Cycle | includes evaporation, condensation, precipitation, and runoff |
| We have 2 high tides | and 2 low tides |
| Tides are caused by | gravitiational pull of Earth, Moon, and Sun |
| Waves | mostly generated by wind |
| Weather | describes day-to-day changes |
| Climate | describes long term weather patterns |
| Areas near the Equator | receive the most isolation |
| High pressures | bring cool and dry weather |
| Low pressures | bring warm and wet |
| Two types of planets | Inner and Outer |
| Inner Planet (rocky) | Mercury, Venus, Earth, and Mars |
| Outer Planet (Gaseous) | Jupiter, Saturn, Uranus, and Neptune |
| Venus' atmosphere | mostly CO2 and dense due to greenhouse effects |
| Comets | known as dirty snowballs |
| Asteroid | rocky or metallic iron objects |
| Apollo 11 | first manned landing on the moon |
| Neil Armstrong | first man on the moon |
| a mineral | found in nature, inorganic, solid, with definite composition and structure |
| Oxygen and silicon | major elements found in Earth's crust |
| Igneous rocks | produced by the cooling of magma or lava |
| Extrusive | fast cooling |
| Intrusive | slow cooling |
| Metamorphic rocks | formed by heat and pressure |
| Sedimentary Rocks | formed from rock fragments, organic material, or chemical precipitation |
| Fossils | found in layers of sedimentary rocks |
