Answer They let light and heat in and keep it in, raising the temperature inside. ____________ is when the surface is heated by electromagnetic Radiation waves in sunlight. Surface benefits more than atmosphere. _____________ is when currents circulate warm air up and cool Convection air down. It is a major cause of weather. _____________ is when objects come in direct contact and Conduction heat is passed from one to the other. Objects resting on the earth’s surface are affected by this. A(n) _________________ front happens when a fast moving Occluded cold front overtakes a slower warm front. What evidence best supports the big bang theory? The galaxies are moving away from each other What direction do weather patterns generally travel in the From west to east United States? On a station model, what is the wind portion pointing to? The direction the wind is coming from What do isolines that are close together mean? It means the slope is steep, the wind is strong, the pressure changes rapidly What measures relative humidity? Psychrometer What does a barometer measure? Atmospheric pressure Lines of equal atmospheric pressure. Isobar Lines of equal temperature. Isotherms Boundary between two air masses. Front 3 What layer of the atmosphere hold most of the Ozone (O )? Stratosphere Heat moving in the atmosphere in the form of wind is caused by Convection currents due to the Sun What heats the air close to the surface of the Earth? Conduction What is the name of the wind that blows from 30 degrees to Trade winds the equator in the northern and southern hemispheres? How do the Ozone (O3) molecules protect the Earth? From the Sun’s harmful ultraviolet (UV) radiation What natural event can contribute to global cooling? Volcanic eruptions What does most research say about carbon dioxide levels and That they are directly related global temperatures Where do hurricanes that affect North America originate from? Warm waters west of Africa What do hurricanes need to build? Heat and moisture What kind of cloud will produce lightning and thunder? cumulonimbus What kind of cloud will produce tornadoes? cumulonimbus What was the early Earth atmosphere composed of? Hydrogen and helium When and how do land breezes move? Toward the sea during the night. When and how do sea breezes move? Toward the land during the day. How do you know what direction the front is moving? The symbols are on the side of the line that the front is moving toward What kind of air do warm fronts bring? Warm, moist What kind of air do cold fronts bring? Cool, dry What happens to a hurricane if it passes over land? It gets weaker Valley & Ridge Long parallel ridges and valleys Appalachian Plateau Contains most of VA’s coal 35. What is the correct order of U.S. space exploration? 36. Which two inner planets have atmospheres composed mostly of carbon dioxide? 37. What are the coordinates for Richmond, VA? 38. What greenhouse gas made it possible for the early atmosphere to absorb and maintain heat? 39. What gas was released by early cyanobacteria? 40. How is hail formed? 41. What is the largest storm on earth? 42. What causes thunder? 43. How is the Earth’s atmosphere layers divided? 44. What is the correct order of the layers of the Earth’s atmosphere from the Earth up? 45. What happens if the global ice cap melts? Mercury, Gemini, Apollo, STS(Shuttle) Program Mars, Venus Approximately 38 degrees N, 75 degrees W Carbon dioxide Oxygen Repeated updrafts within a cumulonimbus cloud Hurricane Expanding superheated air Temperature gradient Troposphere, Stratosphere, Mesosphere, Thermosphere. Earth reflects less light
