Weather and the Oceans
100

As the ocean depth increases, _______ also increases.

water pressure

100

The deepest part of the ocean are the...

Trenches

100

An ocean motion that is caused by wind and seen on the water's surface.

Waves

100

Clouds that occur in fair weather. (They look like cotton balls.)

Cumulus

100

The weight of the air causes:

air pressure

100

What three factors are needed for a thunderstorm to form? 

1. Moisture

2. Lifting Air (convection)

3. Unstable atmosphere

100

Air masses are distinguished by a two letter code.  The first letter describes the ____________ properties and the second letter describes the __________ properties. 

1. moisture

2. temperature

200

The salinity of the ocean varies.  Salinity means...

Saltiness
200

The greatest variety of ocean life is in the shallowest part of the ocean above the...

continental shelf

200

The ocean current which carries warm water from the equator to Europe. (The name of the current)

The Gulf Stream

200

High, thin, wispy clouds.

cirrus clouds

200

Air circulates around the Earth in big chunks called...

air masses

200

These two things can cause an air mass to lift

Cities, mountains (topography)

200

What do these letters stand for?  They describe air masses. 

m                         T                 P

c                          A     


m = moist, maritime

c = dry, continental

T = tropical (warm)

P = polar (cold, dry)

A = arctic (colder and drier than polar)

300

Wind patterns and different water densities cause...

Ocean currents

300

The area at the end of the continental slope where sediments gather causing a small rise in the land.

continental rise

300

As the depth of the ocean increases, these two things  decrease.

Temperature and light

300

Clouds that bring rain and look like a gray blanket covering the sky.

strattus

300

The boundary between two air masses is called a...

FRONT

300

There are two types of air masses.  Name them. 

1. Mountain

2. Sea-breeze

300

This term describes the column of air extending from the ground to the upper atmosphere.  The column of air puts 14.7 pounds per square inch of air on your body. 

Air Pressure

400

It is mostly the pull of the moon's gravity that causes...

Tides

400

The deep flat portion of the ocean floor.

Abyssal plain

400

These plant-like organisms produce much of the Earth's oxygen and serve as the basis of the ocean ecosystem.

Phytoplankton

400

The kind of cloud that forms a tower and brings stormy weather.

Cumulonimbus

400

A warm front occurs when a warm air mass pushes out a cold mass.  A warm front brings:

steady rain or drizzle followed by warmer temperatures

400

This type of rotating column of air forms at the leading edge of a cold front where winds converge to a center of low pressure. 

Tornado (when it touches the ground)

Funnel cloud (does not touch ground)

Water spout (occurs on water instead of land)

400

Name 3 factors that impact climate

1. latitude

2. altitude

3. topography

500

How much does one gallon of water weigh?  

8 pounds....milk weighs more per gallon and gasoline weighs less.  

For a piece of candy or a sticker, can you explain why two liquids of equal volume would have a different mass? 

500

These are underwater mountains caused by plate movements.

mid-ocean ridges

500

Phytoplankton, like other plants, need sunlight for photosynthesis, and therefore live _____________. (Where in the ocean?)

on the ocean's surface.

500

The weather when the barometer is falling showing low pressure. 

Rainy weather

500

A cold front occurs when a cold air mass pushes out a warm air mass.  A cold front brings:

a short period of heavy rain or thunder, followed by clear colder weather.

500

During this stage of storm development, updrafts driven by convection currents bring moisture to the upper atmosphere.  When the updrafts are no longer able to support the weight of the moisture, precipitation falls.  

Cumulus stage (stage 1)

500

In three steps, describe how sea surface temperatures (SSTs) contribute to wet weather on land. 

1. As SSTs rise, the kinetic energy of water molecules increases

2. More energy means more water will evaporate

3. Warm, moist air rises and condenses to clouds, which will fall as precipitation on land.
