Science Interactions Coourse 4 Chapter 3

Front 1

Evacuation

Back 1

Action taken as a devastating storm approaches, when people are asked to leave the area for their safety.

Front 2

Storm surge

Back 2

Usually high rises in the level of the ocean during a hurricane.

Front 3

Salinity

Back 3

Concentration of salt in the environment

Front 4

Gusts

Back 4

Sudden increase in the wind velocity

Front 5

Can hurricanes create tornadoes when they hit land?

Back 5

Yes

Front 6

Do hurricanes redistribute heat from tropical oceans over land?

Back 6

Yes

Front 7

What distinguishes a hurricane from a thunderstorm?

Back 7

Gusty winds

Front 8

Water damage from a hurricane is often more destructive than wind damage. Why?

Back 8

Water can be very destructive and a hurricane can cause flooding.

Front 9

How can people prepare for a hurricane?

Back 9

Evacuate homes, board up windows, stock storm supplies.

Front 10

What is the relationship between an increase in the speed of moving air or water and the force the wind or water exerts?

Back 10

If the speed doubles (2x) the force quadruples (4x)

Front 11

Why do hurricanes eventually die over land?

Back 11

They are cut off form the warm ocean water, and friction is increased causing the storm to loss energy.

Front 12

How do storms damage the marines ecosystem?

Back 12

Salt and mineral content of a part of the ocean may change, shallow water creatures can be damaged.

Front 13

pathogen

Back 13

term for disease causing bacteria or viruses

Front 14

typhoon

Back 14

large violent strom originating in the Pacific Ocean

Front 15

salinity

Back 15

concentration of salt in the environment

Front 16

flash flood

Back 16

sudden rise in a stream or river often causing severe damage to the surrounding country

Front 17

gust

Back 17

sudden increase in the wind

Front 18

tetanus

Back 18

deadly disease caused by bacteria in the soil

Front 19

storm surge

Back 19

unusually high rise in level of ocean during a hurricane that can create a wall of water.

Front 20

erosion

Back 20

wearing away of soil or rock by natural forces such as wind and water

Front 21

counterclockwise

Back 21

describes the direction of a hurricane winds in the Northern hemisphere.

Front 22

Where do most Atlantic Ocean hurricanes start?

Back 22

in warm tropical water west of Africa

Front 23

What ingredients contribute to the formation of a hurricane?

Back 23

low pressure areas, warm ocean, energy from water vapor, the rotation of the Earth

Front 24

The force of wind hitting a building depends on what?

Back 24

The speed of the wind

Front 25

Which hurricane-caused phenomenon is responsible for the most deaths during a storm?

Back 25

storm surges

Front 26

What is one way in which thunderstorms and hurricanes differ?

Back 26

hurricane winds spiral, thunderstorm winds blow in a straight line

Front 27

What are some problems caused by hurricanes?

Back 27

spread of infectious diseases, damage to crops, and interruption of water supply

Front 28

What is one benefit of storms?

Back 28

provide water for plants and animals.

Front 29

What causes the most physical damage from a hurricane?

Back 29

wind and water

Front 30

What are some problems caused by hurricanes?

Back 30

spread of infectious diseases, damage to crops, and interruption of water supply

Front 31

What is one way in which thunderstorms and hurricanes differ?

Back 31

hurricane winds spiral, thunderstorm winds blow in a straight line

Front 32

What happens as a hurricane approaches land?

Back 32

The energy from the wind is transferred to the shallow waters and creates waves.

Front 33

What threat does a hurricane pose to areas far inland?

Back 33

smaller storms, such as tornadoes can spin off and cause damage.
