Chemistry
particles have the least amount of energy so they stay in a fixed position but vibrate. Solids have a definite mass, shape, and volume.
solid
are large bodies of air that have a certain temperature and humidity throughout.
air masses
formed when magma cools underground (intrusive rock) or lava cools above ground (extrusive rock)
igneous
is an object's tendency to resist a change in motion.
inertia
Atoms are the basic units of matter but are made of three subatomic particles.
atomic theory
is anything that has mass and volume.
matter
develop over warm waters in the Caribbean and are characterized by strong winds, heavy rains, and coastal floods
hurricanes
formed when layers of sediments are compacted together over time in bodies of water. They are easily identified because the layers are visible
sedimentary
An object at rest remains at rest, and an object in motion remains in motion at a constant speed in a straight line unless acted on by an unbalanced force.
Newton's First Law of Motion
positively charged particle that is found in the nucleus
proton
a pure substance atom that cannot be separated or broken down into simpler substances by physical or chemical means.
element
are boundaries where two or more air masses meet.
weather fronts
formed underground when rocks are subjected to extreme heat and/or pressure
metamorphic
Whenever one object exerts a force on a second object, the second object exerts and equal and opposite force on the first.
Newton's Third Law of Motion
have no charge, found in nucleus
neutron
a pure substance composed of two or more elements chemically combined.
compound
the atmospheric conditions at a given location at a certain time
weather
the relatively thin layer of gases that surrounds our Earth
atmosphere
The acceleration of an object depends on the mass of the object and the amount of force applied.
Newton's Second Law of Motion
negatively charged particles, orbit nucleus in electron cloud
electron
particles have enough energy to break apart from one another and slide past each other.
liquid
The amount of water vapor in the air as a percentage of the maximum amount the air can hold
relative humidity
lowest layer of the atmosphere in which we live, temperature decreases as altitude increases
troposphere
is a force that opposes motion between two surfaces that are in contact.
friction
H
hydrogen
