science exam

Precipitation

Water in liquid or solid form that falls from the atmosphere

Front

Boundary between 2 air masses

Dew point

Temperature at which air is saturated and condensation can occur

Weather

Atmospheric conditions of a certain place at a certain time

Isobar

Lines that connect all places on a map where pressure is the same

Relative humidity

Amount of water vapor present in the air compared to the maximum amount of water vapor the air could contain that temperature

Isotherm

Lines on a map that connect places with the same temperature

Meteorology

Study of weather

Wind speed, temperature, and air pressure

3 standard weather variables

Gas to liquid

When this happens clouds form

High pressure system

Which sinking air situations usually brings fair weather

Surface report

Which contains measurements of temperature, air pressure, humidity, wind, speed, wind direction, and precipitation

Air mass

What causes weather to remain the same several days in a row

Dropping temperatures

What causes air to reach its dew point

Winds are strong

What do close isobars on a weather map represent

Millibars

Unit of air pressure

G/m³

Unit for humidity

modified Fujitsu scale

Scale used to describe intensity of tornadoes

Stationary

Type of front that forms when a boundary betweeen 2 air masses stall

Occluded

Type of front that forms when a cold front catches up with a slow warm front

Wind direction and speed

Weather variable that describes the wind direction and how fast it blows

Humidity

Weather variable that is the amount of water vapor in the air

Temperature

Measure of average kinetic energy of molecules in the air

Air pressure

Pressure a column of air plies on the air or surface below it

Cloud coverage

How much of the sky is covered by clouds

Thermometer

Instrument that measure temperature of air

Radiosonde

Instrument that measures weather variables above earths surface

Anemometer

Instrument that measures wind speed

Doppler scale

Instrument that measure speed of movement of perception

Barometer

Instrument that measures air pressure

Psychrometer

Instrument that measures relative humidity

Front, precipitation, temperature, and cloud cover

4 things you can see on a weather map

Season

Changes in climate dude to the changing tilt of the earth

Climate

Long term average weather conditions for a particular region

Specific heat

Amount of heat needed to raise the temperature of 1 kg of water by 1 degree Celsius

Greenhouse effect

Term for effect of greenhouse gases on the earths temperature

Global warming

Rise in earths average surface temperature during the past 100 years

Higher

Specific heat of water higher or lower than specific heat of land

Earths orbit, tilt of earth, and slow movement

3 things that cause long term climate cycles

Temperature, precipitation, and vegetation

3 things used to classify climate

Absorb earths radiation

How do greenhouse gases keep earth warm

June 21 or 22

Date of summer solstice

December 21 or 22

Winter solstice

September 22 or 23

Fall equinox

March 21 or 22

Spring equinox

Adhesion

Attraction of unlike molecules

Evaporation

Process of a liquid changing to a gas at the surface of the liquid

Turbidity

Measure of the cloudiness of water, from sediments, organisms

Water quality

Chemical, biological, and physical status of a body of water

Hydrosphere

All the water on and below earths surface and in the atmosphere

Cohesion

Attraction of like molecules to each others

Condensation

Process of a gas changing to a liquid

Transpiration

Evaporation of water from plants

Water cycles

Series of natural processes by which sate continually moves through the hydrosphere

Opposite ends have opposite charge

This makes the water molecule a polar molecule

Less dense

Why do ice cubes float in water

Ice insulates the lake

Why do fish in lakes survive cold winters

Adhesion and cohesion

What moves water from the roots to the leaves of a plant

Oceans

Where is most of the water on earth

Decrease

What happens to oxygen levels in water as it gets hotter

Gravity and suns energy

2 main factors that drive the water cycle

Too much nitrate

What could cause an algal bloom

Secchi disk

Instrument used to measure the level of turbidity of water

Water quality poor

If pollutant intolerant dish are missing in river what does this mean

Water

Substance considered to be the universal solvent

Cryosphere

This is made up of frozen water on earth

Cohesion

Insects walking in water is due to this

Adhesion

Meniscus on a graduated cylinder is due to this

Turbidity, amount of dissolved oxygen, water temperature, and nitrates

4 things that are tested for to determine water quality
