Condensation Level This is a gas made up of three atoms of Oxygen, found in the upper Stratosphere, and absorbs UV radiation. Ozone This is the type of cloud made of ice crystals and resembling the tail of a horse. Cirrus (Mares’ Tails) This is the temperature at which condensation first appears. Dew Point This is the maximum amount of water vapor a certain volume of air can hold at a particular temperature. Saturation Value This is a flat-topped underwater seamount. Guyot This is the measure of the amount of salts dissolved in seawater. Salinity This occurs when sea level rises and causes the shoreline to move inland. Transgression These are rapidly flowing ocean currents that can cut deep-sea canyons in the continental slope. Turbidity Currents This is the branch of earth science dealing with the Earth’s oceans. Oceanography These are dark-colored igneous rocks that are rich in iron and magnesium. Mafic This is the partially molten, plasticlike layer of the Earth located below the solid part of the mantle. Asthenosphere This is the difference in elevation between adjacent contour lines. Contour Interval This is the movement of weathered material from one place to another. Erosion This is Wegener’s hypothesis that Earth’s continents were joined as a single landmass 200 million years ago. Continental Drift This type of chemical bond holds together atoms of opposite charges. Ionic Bond This is molten rock found beneath the surface of the Earth. Magma This is the instrument that measures an earthquakes’s waves. Seismograph This is the soil texture which is a combination of equal parts sand, silt, and clay. Loam Mt. Kilauea, which erupts mostly fluid lava nonexplosively, is this type of volcano. Shield Cone The tails of a comet always point this direction. Away from the Sun This element, along with Helium, makes up most of Jupiter, Saturn, Uranus, and Neptune. Hydrogen Large size, rapid rotation, and many moons and rings would all be characterized by this type of planet. Jovian (Outer) Planet This results when Earth’s orbit intersects a comet’s orbit. Meteor Shower This is interplanetary material that enters the Earth’s atmosphere and collides with the ground rather than burning up. Meteorite
