Ocean Currents, Air Currents and Weather

Multiple Choice

Why are surface currents at the surface of the ocean?

colder temperature

colder temperature & more salinty

warmer temperature & less salinty

less salinty

Multiple Choice

What process brings the deep cold ocean currents up to the surface?

Conduction

Global Wind Patterns

Convection Currents

Temperature and salinity

Multiple Choice

Cold ocean currents generally come from

The North Pole

The South Pole

The Equator

Both A and B

Multiple Choice

Warm ocean currents generally come from

The North Pole

The South Pole

The Equator

Both A and B

Multiple Choice

Ocean currents have an affect on which two things

climate and weather

temperature and density

land and sea

equator and poles

Multiple Choice

Two types of water currents are

local and global

sea and land

surface and deep

warm and cold

Multiple Choice

________ and _______ affect the ocean's density and cause the Global Conveyor Belt to travel

gravity and the Coriolis Effect

temperature and salinity

wind and climate

temperature and the Coriolis Effect

Multiple Choice

_______ causes the Coriolis Effect

Earth's rotation

gravity

wind

density

Multiple Choice

Nutrients are brought to the surface for phytoplankton to use at _______.

gyres

eddies

upwellings

the equator

Multiple Choice

Decreasing ocean temperature causes the density of the water to ______.

decrease

increase

stay the same

fluctuate

Multiple Choice

______ causes deep ocean currents

The Coriolis Effect

gravity

wind

density differences

Multiple Choice

______ causes surface currents.

The Coriolis Effect

gravity

density differences

wind

Multiple Choice

The average weather conditions of a region--

daily temperature

weather

climate

Multiple Choice

The main reason that we have currents in the ocean and air is

the sun heats the air and ocean evenly everywhere

the heat inside the earth heats the ocean and the ocean heats the air

the sun cannot heat both the air and water, so one must heat the other

the sun heats air and water more at the equator because it receives more direct sunlight

Multiple Choice

The condition of the air outdoors is-

climate

weather

average temperature

Multiple Choice

What causes winds to form on Earth?

solar energy

ocean currents

elevation differences

uneven heating of the Earth by the sun

Multiple Choice

Which of the following is true about the unequal heating of land (sand) and water?

land/sand heats up and cools off faster than water

water heats up and cools off faster than land/sand

land and water heat and cool at the exact same rate

Multiple Choice

Which system causes clear skies and nice weather?

High Pressure

Low Pressure

Multiple Choice

Which system causes storms and cloudy weather?

High Pressure

Low Pressure

Multiple Select

An air mass has similar .....

check all that apply

temperature

color

humidity

air pressure

shape

Multiple Choice

The boundary that forms between two air masses when they meet is called a...

front

storm line

squall line

midaltitude

Multiple Choice

What is an air mass?

large body of air that has about the same characteristics

large body of air that has different characteristics

Weather Instruments

Ways to Measure Our Weather

Barometer

Measures air pressure.

Anemometer

Measures wind speed.

Rain Gauge

Measures the amount of rain that has fallen over a specific time period.

Sling Psychrometer

Measures the relative humidity of the air.

Thermometer

Measures the temperature of the air.

Weather Balloon

An instrument sent into the atmosphere to provide information about the weather.

Wind Vane

Determines the direction from which the wind is blowing.
