An organized approach to

gathering, analyzing, verifying,

and utilizing information

about the world.

Suggested answer

to a question.

A logical explanation based on

data gathered and verified

by many scientists.

The systematic study of

solid Earth, the water on it,

and the air around it,

as well as Earth's place

in the universe.

The study of solid Earth,

including Earth's surface

and interior.

The study of Earth's atmosphere

and its changing conditions.

The study of the characteristics

and dynamics of Earth's oceans,

which cover about 70%

of the planet.

The study and protection

of the environment.

A piece of information

obtained directly

through our

senses.

Observation that is

relative,

but

not

specific.

Observation

when you count

objects or make a

measurement.

INTERNATIONAL

SYSTEM OF

MEASUREMENT

(SI)

A decimal system of

measurement.

(These mix of units are related

in multiples of 10.)

An imaginary line

around Earth

located halfway

between the poles.

An imaginary straight line

through the planet

between the North Pole

and the South Pole.

The force of attraction

that every object

in the universe

exerts on

every other object.

Equal to the

gravity (g) times (x) mass (m)

The land, or solid part

of Earth.

Includes oceans, rivers and

streams, ponds and lakes,

and other bodies of water,

covering about 70%

of the lithosphere.

The shell of gases

that surrounds

Earth.

The lowest layer of the Earth,

which becomes cooler

as you rise to the top.

The top boundary

of the troposphere,

at which the temperature

decrease stops.

The layer above the

troposphere which has

strong, steady winds,

such as jet stream.

The lower end of the stratosphere

is as cold as the top of the

tropopause, but it warms up

as you rise to its top.

The next layer after the stratosphere,

in which temperature

decreases with height.

The next layer after the stratosphere,

in which temperature

increases with height.

All living things

are part of this

on Earth.
