meteorology

the study of weather

precipitation

moisture falling from the atmosphere as rain or snow or hail

air pressure

A force exerted onto a surface by a weight of air molecules

matter

anything that takes up mass or space

atoms

the smallest chemical unit of matter

molecules

2 or more atoms linked together to make a substance with unique properties

mixtures

a substance that contains different compounds and/or elements

physical change

a change in which the atoms or molecules in a substance stay the same

chemical change

a change that affects the type of molecules or atoms in a substances

is the day to day state of the atmosphere, sometime changing hourly

weathering

has to do with the conditions of a long period of time

climate

is the closest layer of the earths surface

troposphere

is the second layer to the earths surface

stratosphere

mesosphere

is the third layer to the earths surface

is the fourth layer earths surface

theremosphere

exosphere

is the highest layer of our atmosphere

which one of these do airplanes fly in

stratosphere

which of these layer is consider the exit layer

exosphere

what are three step to the hydro-logic system

1.water evaporates

2. condensation

3. precipitation

what are the three major types of clouds and describe them

1. cumulus - white puffy clouds with a flatten bottom

2. stratus - they look like layer of strata

3. cirrus- from a high altitude and are feathery in appearance

is the study of the oceans

oceanography

ocean covers - of our planet

warm front

is the mass of warm air

cold front

a mass push of cold air

what is the difference between warm front and cold front

warm front is when a warm air pushes out or against a cold front

cold front is when a mass push of cold air pushes out a warm front

the atmosphere can be divided into 2 majors region, what are they

heteroshpere and hemosphere

if a scientist add heat to a solid material so that it becomes a liquid, what do we call the temp at this happened

melting point

rusting iron is an example of what of what kind of change

chemical

positive ions are called

cations

negative ions are called

anions

bonding is when 2 more atoms share a pair of electrons

convent bond

bond are formed when ions are attracted to each other

ionic
