weather - natural movement of air on Earth, caused by the Sun's uneven heating of the Earth's surface, which creates differences in air pressure, barometer - scientific instrument used to measure atmospheric pressure, atmosphere - Earth's protective bubble of air (a mixture of gases like nitrogen and oxygen) that surrounds our planet, providing the air we breathe, regulating our temperature, and shielding us from space, ozone - acts like a protective shield, absorbing the sun's harmful ultraviolet (UV) rays before they can reach us, water vapor - forms when the sun or other heat energy causes liquid water from oceans, lakes, or even a puddle to turn into a gas, convection - the transfer of heat through the movement of a liquid or gas, like boiling water or air rising, anemometer - a scientific tool that measures the speed and sometimes the direction of the wind, greenhouse effect - the natural warming of Earth when gases in the atmosphere trap the sun's heat, density - measure of an object's mass compared to its volume, air pressure - the force of air pushing on everything around it, altitude - location's height above sea level, mesosphere - the middle layer of Earth's atmosphere where most meteors burn up, protecting Earth, conduction - when heat energy moves between objects or particles that are touching., wind vane - weather instrument that spins in the wind to show which direction the wind is blowing from, pressure - force pushing on a surface divided by the area it pushes on, troposphere - the lowest layer of Earth's atmosphere, the part of the air we live in, thermosphere - the hottest and thickest layer of Earth's atmosphere, located just before outer space, radiation - energy or tiny particles traveling through space, coriolis effect - a force that makes moving things on Earth, like air and water currents, appear to curve instead of moving in a straight line, mercury - it's a heavy, silver, metallic element that is liquid at normal temperatures and is used in thermometers, aneroid barometer - a tool for measuring air pressure that doesn't use any liquid, stratosphere - the second layer of Earth's atmosphere, found above the layer where we live (the troposphere) and below the mesosphere, exosphere - the outermost layer of Earth's atmosphere, where the air is so thin that atoms and molecules can escape into space,
