Composite VolcanoSometimes called stratovolcanoes, are typically deep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 ft above their bases.,
Drainage BasinA drainage basin is an extent of land where water from rain and melting snow or ice drains downhill into a body of water, such as a river, lake, reservoir, estuary, wetland, sea or ocean.,
FaultingThe process in which internal forces cause Earth’s crust to break and slide along a fracture called a fault.,
GraphiteA form of the element carbon in which carbon atoms form flat layers.,
Latent HeatThe quantity of heat absorbed or released by a substance undergoing a change of state, such as ice changing to water or water to steam, at constant temperature and pressure. Also called heat of transformation.,
Metamorphic RockA rock produced igneous & sedimentary rock go through change by heat, pressure, or both.,
Nuclear ReactorIs a device to initiate and control a sustained nuclear chain reaction. The most common use of nuclear reactors is for the generation of electrical power and for the power in some ships. This is usually accomplished by methods that involve using heat from the nuclear reaction to power steam turbines.,
PlutoA dwarf planet that until 2006 was classified as the ninth planet in our solar sytem, having a sidereal period of revolution about the sun of 248.5 years, 4.4 billion kilometers (2.8 billion miles) distant at perihelion and 7.4 billion kilometers (4.6 billion miles) at aphelion, and a diameter less than half that of Earth.,

UranusThe planet seventh in order from the sun, having an equatorial diameter million miles (2,871 million km), a period of revolution of 84.07 years, and 15 moons.of 32,600 miles (56,460 km), a mean distance from the sun of 1,784,
WesterliesThe Westerlies, anti-trades or Prevailing Westerlies, are the prevailing winds in the middle latitudes between 35 and 65 degrees latitude, blowing from the high pressure area in the horse latitudes towards the poles.,
