Climate is the description of _____ weather conditions. Long-term, regional TERM 2 The earth's earliest atmosphere was probably composed mainly of ______, which has/have since largely dissipated into space. DEFINITION 2 Hydrogen and helium TERM 3 Elements such as _______ were added to the Earth's early atmosphere through _____. DEFINITION 3 Carbon, nitrogen, oxygen and sulfur; volcanic emissions TERM 4 The atmospheric zone where most weather events occur is DEFINITION 4 Troposphere TERM 5 The two main gases making up the lower atmosphere are DEFINITION 5 Nitrogen and oxygen
Aerosols are tiny particles and droplets suspended in the air TERM 7 The correct sequences of atmospheric zones upward from the earth's surface is DEFINITION 7 Troposphere, stratosphere, mesosphere, thermosphere TERM 8 The different layers of the atmosphere are kept from mixing by DEFINITION 8 Sharp temperature boundaries TERM 9 The "ozone hole" that causes concern among scientists and the public is an ozone depletion in the DEFINITION 9 Stratosphere TERM 10 In the diagram, which layer(s) has/have a rapid drop in temperature with increasing altitude? DEFINITION 10 Both I and III
Which of the following would be the highest albedo A snowfield TERM 17 Eventually,all of the energy that reaches the Earth's surface is DEFINITION 17 reflected or radiated back to space TERM 18 Energy absorbed at the Earth's surface is radiated back to space in the form of DEFINITION 18 Infrared radiation (heat) TERM 19 Intense sunlight causes a band of hot, rising air laden with evaporated water near the equator. This moisture then falls because DEFINITION 19 The rising air cools and loses it ability to hold water vapor TERM 20 The greenhouse effect in the atmosphere occurs because DEFINITION 20 CO2, water vapor, methanol and other gases absorb infrared radiation
The phenomenon causing the greenhouse effect is that _____ in the lower atmosphere selectively absorbs reradiated___ radiation. Carbon dioxide, methane and other gases, infrared(heat) TERM 22 Convection currents in the atmosphere are driven by DEFINITION 22 The different temperatures and densities of warm and cold air masses TERM 23 When an area of the Earth's surface becomes very hot, the air above it DEFINITION 23 Warm, expands and rises TERM 24 When cool, dry air sinks from the upper atmosphere toward the Earth's surface it is DEFINITION 24 Compressed and becomes warmer TERM 25 Rising, expanding air masses create a region of DEFINITION 25 Low pressure
The boundary between two air masses of different temperature and density is known as a Front TERM 32 Narrow, violent bands of rain and storms are characteristic of DEFINITION 32 Advancing cold fronts TERM 33 If you see high wipsy cirrus clouds with layers of other clouds in a wedge shape, you can expect _____ due to an ____. DEFINITION 33 Drizzle ad cloudy skies; advancing warm front TERM 34 Hurricane are powered by DEFINITION 34 heat released from condensing water vapor TERM 35 Why don't storms over land have as much energy as storms over oceans? DEFINITION 35 Convection currents are intensified by the latent energy of condensation
Which of the following events is NOT part of the explanation of how tornadoes form? The air mass is set spinning by the Coriolis effect TERM 37 Milankovitch cycles involve the periodic _____ and could be responsible for _____ weather changes. DEFINITION 37 Wobbling of the earth's axis and the orbital shifts ; cyclic TERM 38 When El Nino occurs every three to five years, a mass of warm Pacific water that is usually pushed westward by trade winds DEFINITION 38 Surges back eastward toward South America TERM 39 As far we are currently aware, who were the first people to notice the El Nino Southern Oscillation cycle? DEFINITION 39 Peruvian fisherman TERM 40 Proponents of climate change says that given what we know about the probability of the greenhouse effect the best thing to do is DEFINITION 40 Severely cut back on production of Greenhouse gaes
Ocean circulation pattern have no effect on climate conditions on land. (True or False) False TERM 47 Most of the excessive carbon dioxide that is expected to cause global warming is generated by green plants. (True or False) DEFINITION 47 False TERM 48 Since biodiversity is usually higher in warmer, milder climates, biodiversity will probably be increased with global warming. (True or False) DEFINITION 48 False
