The Atmosphere

Chapter 1 Weather and Climate

Key TermDefinition
weather The condition of Earth's atmosphere at a particular time and place.
atmosphere The layer of gases that surrounds Earth.
ozone A form of oxygen that has three oxygen atoms in each molecule instead of the usual two.
water vapor Water in the form of a gas.
pollutant Harmful substances in the air, water or soil.
photochemical smog A brownish haze that is a mixture of oxone and other chemicals, formed when nitrogen oxides, hydrocarbons and other pollutants react with each other in the presence of sunlight.
acid rain Rain that contains more acid than normal.
density the amount of mass of a substance to a given volume.
pressure The force pushing on an area or surface.
air pressure A force that is the result of the weight of a column of air pushing down on an area.
barometer An instrument used to measure changes in air pressure.
mercury barometer An instrument that measures changes in air pressure, consisting of a glass tube partially filled with mercury, with its open end resting in a dish of mercury. Air pressure pushing on the mercury in the dish forces the mercury in the tube higher.
aneroid barometer An instrument that measures changes in air pressure without using a liquid. Changes in the shape of an airtight metal box cause a needle on the barometer dial to move.
altitude Elevation above sea level.
troposphere The lowest layer of Earth's atmosphere, where weather occurs.
stratosphere The second-lowest layer of Earth's atmosphere; the ozone layer is located in the upper stratosphere.
mesosphere The middle layer of Earth's atmosphere; the layer in which most meteroroids burn up.
thermosphere The outermost layer of Earth's atmosphere - the ionosphere and the exosphere make up the thermosphere.
ionosphere The lower part of the thermosphere, where electrically charged particles called ions are found.
aurora borealis A colorful, glowing display in the sky caused when particles from the sun strike oxygen and nitrogen atoms in the ionosphere; also called the Northern Lights.
exosphere The outer layer of the thermosphere, extending outward into space.
Lewis structure An electron dot diagram where valence electrons are represented as dots.
electrons A tiny, negatively charged particle that moves around the nucleus of an atom.
protons A small, positively charged particle in the nucleus of the atom.
neutrons A small particle in the nucleus of the atom, with no electrical charge.
valence electrons One of the electrons farthest away from the nucleus of the atom; these electrons are involved in a chemical reaction.
