Weather

Question 1

Define Albedo

Answer 1

The reflectivity of a surface. High albedo surfaces reflect sunlight while low albedo surfaces absorb light

Question 2

Define atmospheric pressure

Answer 2

The weight of air pushing down on itself on the surface. Warmer areas have lower pressure air (Less and farther apart air molecules). Cooler areas have higher pressure air (more/closer molecules)

Question 3

Climate

Answer 3

The average weather conditions of a place over many years

Question 4

Convection

Answer 4

The transfer of energy through the movement of particles in gas or liquid. It produces convection currents.

Question 5

Coriolis effect

Answer 5

As Earth rotates it causes global winds to blow diagonal over the Earth’s surface

Question 6

Equinox

Answer 6

When Earths axis isn’t tilted towards or away from the sun, causing 12 hours of the day and night.

Question 7

When is Fall and Spring equinox?

Answer 7

September 22 and March 20

Question 8

Frontal boundary

Answer 8

The boundary between warm and cold air maseu

Question 9

Humidity

Answer 9

The amount of moisture/water vapour in the air

Question 10

Prevailing winds

Answer 10

A surface wind that blows predominantly from a particular place or season

Question 11

Solstice

Answer 11

The 2 days a year where the sun reaches its maximum or maximum distance from Earth. The longest and shortest days.

Question 12

Weather

Answer 12

Day to day environmental conditions

Question 13

What gases make up the atmosphere? How much of each

Answer 13

78% nitrogen, 21% oxygen, 1% other gases: water vapour, argon, carbon dioxide

Question 14

What is the Troposphere?

Answer 14

The first layer, weather occurs here, contains 75% of the air in the atmosphere, and almost all water. Contains Nitrogen, oxygen and other gases

Question 15

What is the stratosphere?

Answer 15

The second layer, contains the most ozone layer, temperature increases with height, absorbs UV radiation

Question 16

Mesosphere

Answer 16

The third layer, gas molecules are dense, it slows down meteors and burns them up (shoot stars)

Question 17

Thermosphere

Answer 17

The fourth layer, solar particles trapped here mix with gases make light (auroras) the ISS orbits here.

Question 18

Exposphere

Answer 18

The fifth layer, no air molecules in there, it’s where space shuttles and satellites orbit earth here

Question 19

What layer of the atmosphere do you find the ozone layer?

Answer 19

The stratosphere

Question 20

What layer of the atmosphere does weather occur?

Answer 20

The troposphere

Question 21

What layer of the atmosphere has no air molecules

Answer 21

The exosphere

Question 22

Evaporation

Answer 22

Liquid changing into gas

Question 23

Melting

Answer 23

Solid changing to liquid

Question 24

Sublimation

Answer 24

Solid changing to gas

Question 25

Condensation

Answer 25

Gas changing to liquid

Question 26

Freezing

Answer 26

Liquid changing to solid

Question 27

Deposition

Answer 27

Gas changing to solid

Question 28

How does the water cycle relate to weather

Answer 28

It’s constantly moving water through the Earth’s atmosphere making precipitation

Question 29

Explain what makes something a good heat sink

Answer 29

A good hear sink is a large surface made from materials with high thermal conductivity like copper

Question 30

Explain a bad heat sink

Answer 30

A bad heat sink has small surface area made from materials with low thermal conductivity like plastic or wood

Question 31

Whats low pressure in the atmosphere

Answer 31

Air with lower pressure at its centre causes wind to blows counterclockwise pushing warm air upwards. The water vapour within condenses making precipitation.

Question 32

Air with high pressure

Answer 32

Air with higher pressure at its centre causes wind to blow clockwise pulling cold air downwards to fill space below it.

Question 33

Artic (cP)

Answer 33

The Arctic ocean and surrounding coastline, it brings low humidity, dry, and cold weather.

Question 34

continental polar (cP)

Answer 34

Northarn Canada or Alaska

Question 35

continental tropical (CT)

Answer 35

Near the equater

Question 36

maritime polar

Answer 36

North Pacitic and North Alantic Orean

Question 37

maritime tropical

Answer 37

Gulf of Mexico
