5Th Grade Ocean And Weather

Front 1

what is a thermometer

Back 1

this device measures the temperature of the air

Front 2

what does it mean to have a low pressure area

Back 2

this kind of air pressure usually means bad weather is on the way

Front 3

what is an anemometer

Back 3

this device measures wind speed

Front 4

what is the water cycle

Back 4

this is where water runs off into streams,lakes and oceans; the water then evaporates and goes up into the clouds; the water droplets get heavier and heavier and eventually fall to the ground in the form of precipitation

Front 5

what is a cumulonimbus cloud

Back 5

these are tall clouds; they are a type of cumulus cloud; they bring thunderstorms; and they are usually called thunderclouds

Front 6

what is rain gauge

Back 6

this device measures the amount of rain we get

Front 7

what are cirrus clouds

Back 7

these are high, wispy clouds; they are made mostly of ice crystals; and they usually mean good weather

Front 8

what is a hygrometer

Back 8

this device measures the amount of humidity in the air

Front 9

what does it mean if we have a high pressure area

Back 9

this area of pressure usually means good weather

Front 10

what happens to the energy from the sun's rays that reach the earth

Back 10

50% of this is absorbed by the earth's surface and 5% of it is reflected off the earth's surface

Front 11

what is wind

Back 11

this is caused by the surface of the earth being heated unevenly by the sun

Front 12

what is climate

Back 12

this is the average of all weather conditions through all seasons over a period of time

Front 13

what is a local wind

Back 13

this is the wind in your area

Front 14

what determines climate

Back 14

temperature, precipitation, wind speed, and wind direction have a direct effect on this

Front 15

what are land breezes

Back 15

this is caused by sea breezes moving away toward the land; at night they cool off and move back toward the sea

Front 16

what are prevailing winds

Back 16

these are global winds that blow from the same direction. they are caused by the uneven heating of large parts of the earth's atmosphere and by the earth's rotation

Front 17

what is temperature

Back 17

this is determined by latitude or how far a place is from the equator

Front 18

what are the different types of winds

Back 18

polar easterlies, northeast tradewinds, southeast tradewinds, prevailing westerlies, and jet streams are types of this

Front 19

what affects the climate

Back 19

the distance a place is from the equator; the amount of precipitation, the winds, ocean currents; and the shape of the land itself affects this

Front 20

what is a cumulus cloud

Back 20

these are piled up, puffy clouds which usually means fair weather; but it can produce some type of precipitation too

Front 21

what are sea breezes

Back 21

these are winds that move away from shore toward land

Front 22

what is the greenhouse effect

Back 22

this is where carbon dioxide absorbs some of the heat given off by the earth

Front 23

what is global warming

Back 23

this is a prediction that scientists have made in which excess carbon dioxide makes the termperatures rise on earth

Front 24

what is a stratus cloud

Back 24

this type of cloud looks like "layers of clouds" in the sky; they often produce rain or snow. if they touch the ground, it is called fog

Front 25

what is a surface current

Back 25

this is an ocean current that is caused by prevailing winds

Front 26

what is a rip current

Back 26

this is a current that flows away from the beach quickly and causes trouble for swimmers

Front 27

what causes a rip current

Back 27

this is where a long ridge of sand forms offshore from the beach and the waves can't pass back over it until a small break opens up. the water then flows over it quickly, producing a strong current

Front 28

what is the gulf stream

Back 28

this is a warm ocean current that flows from the Caribbean, past the east coast of the United States, and across the North Atlantic Ocean

Front 29

why can palm trees grow along the southern coast of England

Back 29

the Gulf Stream makes this climate mild enough to grow palm trees along the southern coast of England

Front 30

what is a shoreline current

Back 30

these are local ocean currents that run along the coast

Front 31

what is a longshore current

Back 31

this when waves strike the shore at an angle and then move water forward along the shore. this is the type of current that "erodes" the beach and "deposits" the sand somewhere else

Front 32

what does the earth's rotation do the ocean currents

Back 32

this causes the ocean currents to bend to the right in the northern hemisphere and to the left in the southern hemisphere

Front 33

what causes deep ocean currents

Back 33

the differences in water temperature cause this type of ocean current

Front 34

what causes high and low tide

Back 34

these are caused by the gravity of the sun and the moon on the earth's waters

Front 35

what has the greatest effect on the tides

Back 35

the moon has the greatest effect on this because it is closer to the earth

Front 36

what is a tidepool

Back 36

this is a pool of seawater found along a rocky shoreline

Front 37

how much of the earth's surface is covered by water

Back 37

70% of this covers the earth's surface

Front 38

what is a wave

Back 38

this is the up and down movement of surface water

Front 39

what causes a wave to slow down when it comes ashore

Back 39

friction with the bottom of the ocean causes this to happen to a wave as it gets close to shore

Front 40

what produces waves

Back 40

the wind produces this in the ocean

Front 41

what is a storm surge

Back 41

this is a large amount of water that comes ashore during a hurricane

Front 42

what determines the height of the waves

Back 42

this is determined by how hard the wind blows

Front 43

what is a rogue wave

Back 43

this is a huge wave that is formed when large storm waves join together

Front 44

what is an ocean current

Back 44

this is a stream of water that flows like a river through the ocean

Front 45

what is a tsunami

Back 45

this is a giant wave that is caused by an earthquake

Front 46

what does the word sonar mean

Back 46

this is a device that uses sound waves. scientists use this to map the ocean floor
